What Is a Calcaneus Fracture?
The calcaneus — commonly called the heel bone — is the largest bone in the foot and the most commonly fractured tarsal bone. It bears the full weight of the body with every step, forming the foundation of the hindfoot complex. In car accidents, calcaneus fractures are caused by a specific and devastating mechanism: floor pan intrusion.
When a vehicle sustains a high-speed frontal collision, the crumple zone collapses and the floor pan of the passenger compartment is driven upward into the footwell. If the driver's foot is positioned on the brake pedal or accelerator at the moment of impact — as it almost always is — the rising floor pan forces the foot upward. The talus, the ankle bone sitting directly above the calcaneus, is simultaneously driven downward by the weight and inertia of the body. The result is a catastrophic axial compression: the talus is rammed into the calcaneus with thousands of pounds of force, shattering the heel bone and destroying the subtalar joint that lies between them.
This is not a minor fracture. Calcaneus fractures — particularly the displaced intra-articular fractures that constitute 75% of all calcaneus fractures — are among the most serious lower extremity injuries in orthopedic trauma. They frequently result in permanent disability, chronic pain, inability to perform physical work, and ultimately the surgical elimination of the subtalar joint through subtalar fusion.

Calcaneus Anatomy: Understanding the Injury
Understanding the anatomy of the calcaneus is essential to understanding why these fractures are so devastating and why they create substantial legal claims.
The Subtalar Joint: Three Facets, One Critical Function
The subtalar joint — the joint between the calcaneus and the talus above it — consists of three articular facets: the posterior facet (the largest, bearing the majority of load), the middle facet, and the anterior facet. Together, these three facets allow the hindfoot to invert and evert — to roll inward and outward — which is the motion required for walking on uneven terrain, going up and down stairs, and absorbing ground reaction forces during normal gait. When the talus is driven into the calcaneus during floor pan intrusion, it is the subtalar joint facets — primarily the posterior facet — that are destroyed. This articular cartilage destruction is permanent and cannot be repaired by surgery: ORIF can attempt to restore the anatomy of the joint surfaces, but articular cartilage does not regenerate, and post-traumatic arthritis is the inevitable long-term consequence.
Böhler's Angle and the Critical Angle of Gissane
Two radiographic measurements on the lateral X-ray of the calcaneus define fracture severity. Böhler's angle — formed by lines drawn from the anterior process to the posterior facet summit and from the posterior facet summit to the posterior tuberosity — is normally 25 to 40 degrees. A calcaneus fracture that collapses the posterior facet reduces Böhler's angle; the more severe the fracture, the lower the angle. An angle below 20 degrees indicates significant depression; below 10 degrees represents near-total facet collapse. The critical angle of Gissane is formed at the junction of the posterior and anterior facet surfaces on lateral X-ray and is normally 95 to 105 degrees; widening indicates posterior facet comminution. These measurements appear on the initial emergency X-ray and provide the attorney with objective, quantified, contemporaneous evidence of fracture severity documented at first medical contact.
Achilles Tendon Insertion and the Calcaneal Tuberosity
The Achilles tendon — the strongest tendon in the body — inserts into the posterior calcaneal tuberosity. Calcaneus fractures involving the posterior tuberosity can disrupt the Achilles tendon insertion, causing an avulsion fracture in which the tendon pulls a fragment of bone away from the calcaneus. These avulsion fractures require urgent surgical fixation to restore Achilles tendon continuity and prevent retraction of the tendon fragment. The calcaneocuboid joint — the articulation between the anterior process of the calcaneus and the cuboid bone — is involved in anterior process fractures, a separate but clinically significant fracture type that causes chronic lateral midfoot pain.
Sanders Classification: The CT-Based Gold Standard
The Sanders classification system — based on CT scan with coronal reconstructions through the widest point of the posterior facet — is the gold standard for classifying displaced intra-articular calcaneus fractures. It grades fractures by the number of fracture lines in the posterior facet and the resulting number of articular fragments.
Sanders Type I — Non-Displaced
Any number of fracture lines, but no fragment is displaced more than 2 mm. The articular surface remains congruent. Treatment: non-weight-bearing cast or boot for 6 to 10 weeks. Best prognosis. Still eligible for legal recovery if causally related to the accident and producing functional limitation.
Sanders Type II — Two Fragments
One fracture line divides the posterior facet into two articular fragments. Three subtypes (IIA, IIB, IIC) based on fracture line location. Treatment: ORIF with calcaneal plate and screws via extensile lateral approach — requires waiting for the "skin wrinkling sign" at 10-21 days. Good-to-fair prognosis; significant post-traumatic arthritis risk.
Sanders Type III — Three Fragments
Two fracture lines create three articular fragments. A central depression fragment is characteristically depressed and impacted. Treatment: ORIF with calcaneal plate; some surgeons prefer primary subtalar fusion for selected Type III fractures due to poor articular reconstruction prognosis. Fair-to-poor prognosis; majority develop significant post-traumatic subtalar arthritis requiring late subtalar fusion.
Sanders Type IV — Severely Comminuted
Four or more articular fragments — the posterior facet is essentially destroyed beyond meaningful reconstruction. Treatment: primary subtalar fusion is the treatment of choice; ORIF is not attempted because anatomic articular restoration is impossible. Worst prognosis. These cases represent the highest settlement and verdict values in calcaneus fracture litigation.
Intra-Articular vs. Extra-Articular: The Critical Distinction
Approximately 75% of calcaneus fractures are intra-articular — they involve one or more of the subtalar joint facets, most commonly the posterior facet. These are the fractures caused by the axial loading mechanism of floor pan intrusion and are associated with the worst long-term outcomes. Extra-articular fractures (25%) include anterior process fractures, calcaneal tuberosity avulsion fractures (Achilles attachment), and stress fractures; these have a better prognosis but still cause significant pain and disability. The Essex-Lopresti classification further divides intra-articular fractures into tongue-type (fracture line extends to the posterior tuberosity, creating a tongue-shaped fragment) and joint depression-type (central fragment depressed into the calcaneal body), which have different surgical implications.
How Car Accidents Cause Calcaneus Fractures
Floor Pan Intrusion in Frontal High-Speed Crashes
Floor pan intrusion is the dominant mechanism for calcaneus fractures in car accidents and is the most important mechanical fact your attorney must establish. When a vehicle strikes another vehicle, a barrier, or a fixed object at speed, the front end collapses in a controlled crumple designed to absorb energy. However, in high-speed or offset frontal collisions, the floor pan of the passenger compartment intrudes upward into the footwell. The driver's right foot — positioned on the brake pedal — is trapped between the rising floor pan and the pedal. The axial load is transmitted up through the foot in a fraction of a second, with the talus driven into the calcaneus from above and the floor pan driven into the plantar surface of the heel from below. The resulting compressive force is catastrophic.
Accident reconstruction engineers can calculate the delta-V (change in velocity) of the crash, measure floor pan intrusion from post-crash vehicle inspection, and quantify the axial load transmitted through the foot using biomechanical models. This expert analysis is essential for countering defense arguments that the impact was too low-energy to cause a calcaneus fracture — a common tactic when the defense hires its own biomechanical expert.
Panic Braking Mechanism
A secondary mechanism that amplifies calcaneus fracture severity is panic braking in the moments before impact. When a driver sees a collision about to occur, the natural reflex is to brake hard — pressing the brake pedal with maximum force. This pre-loads the calcaneus under axial compressive stress at the exact moment the collision occurs, effectively adding the driver's own braking force to the crash-generated axial load. This combined loading is greater than either force alone and contributes to the severity of the calcaneal comminution. In litigation, this mechanism is important because it explains why a calcaneus fracture can occur even in moderate-speed crashes: the panic braking force is additive to the crash force.
Additional Car Accident Mechanisms
Left Foot Bracing Against Firewall
In automatic transmission vehicles, some drivers reflexively brace their left foot against the firewall, dashboard, or floor during a panic stop. This creates the same axial loading mechanism as the right foot on the brake pedal, producing a left calcaneus fracture — sometimes bilateral when both feet are loaded simultaneously.
Motorcycle Accidents
Motorcyclists whose foot strikes the ground at impact, or who are thrown and land on their feet, sustain calcaneus fractures through the same axial loading mechanism. Bilateral calcaneus fractures are particularly common in motorcyclists who land on both feet after being ejected.
Pedestrian Knockdown
Pedestrians struck by vehicles are often thrown into the air and land on their heels, transmitting axial load through the calcaneus. The height of the throw and the hardness of the landing surface (concrete sidewalk versus asphalt) determine fracture severity.
Passenger Footrest Impact
Front-seat passengers who have their feet on the dashboard or footrest at the time of a frontal collision may sustain calcaneus fractures when the floor pan rises or the footrest is driven into the foot. This mechanism also commonly produces bilateral knee injuries (dashboard knee) simultaneously.
"Don Juan" Injury Pattern: Bilateral Calcaneus Fractures + Lumbar Spine Fracture
The "Don Juan" injury pattern — also called "lover's jump" syndrome — describes the simultaneous occurrence of bilateral calcaneus fractures and lumbar compression or burst fractures from a single catastrophic axial loading event. The mechanism was originally described in falls from height, but it occurs in severe car accidents through the same physics: when both lower extremities absorb simultaneous axial loading forces, the energy travels proximally from both heels, up through both tibiae, femora, and pelvis, and concentrates in the lumbar spine, fracturing the vertebral bodies as the energy dissipates.
This pattern is critical to recognize for two reasons. First, a missed lumbar burst fracture in a patient presenting with heel pain represents a serious failure of emergency care — lumbar burst fractures with posterior element involvement can compress the spinal cord or cauda equina, causing permanent neurological deficits if not identified and surgically decompressed. Second, the presence of a lumbar spine fracture in addition to bilateral calcaneus fractures dramatically increases the value of a personal injury case: it adds spinal damages, potential neurological deficit claims, anterior discectomy or pedicle screw fixation surgical costs, and chronic lumbar pain to the existing heel bone damages.
Standard of Care After Bilateral Calcaneus Fractures
The standard of care in orthopedic trauma requires lumbar spine imaging — at minimum AP and lateral lumbar X-rays, and typically a CT scan of the lumbar spine — whenever bilateral calcaneus fractures are diagnosed. If your emergency physician or orthopedic surgeon failed to order spine imaging after bilateral calcaneus fractures, and you were later found to have a lumbar fracture, this may constitute medical malpractice in addition to your personal injury claim against the at-fault driver. Your attorney should review the emergency records immediately to determine whether the spine was imaged.
Diagnosis and Treatment of Calcaneus Fractures
Diagnosis: Imaging Requirements
Plain X-Rays — Initial Screening
Standard calcaneus X-ray series includes AP (anteroposterior), lateral, and Harris heel (axial) views of the foot, plus Broden views (oblique views at specific angles to visualize the posterior facet surfaces directly). The lateral X-ray is the most important initial view: it shows Böhler's angle, the critical angle of Gissane, and gross fracture morphology. However, plain X-rays alone are insufficient for definitive fracture characterization.
CT Scan — Mandatory for All Displaced Fractures
CT scan with sagittal, axial, and coronal reconstructions is mandatory for all displaced calcaneus fractures. The coronal reconstruction through the widest point of the posterior facet is the view used for Sanders classification. CT defines the number of articular fragments, the degree of depression, the extent of posterior facet comminution, lateral wall blow-out (which impinges the peroneal tendons), subtalar joint involvement, calcaneocuboid joint involvement, and the relationships of all major fragments. Without CT, neither accurate Sanders classification nor surgical planning is possible.
MRI — Soft Tissue Evaluation
MRI is used to evaluate associated soft tissue injuries not visible on X-ray or CT: peroneal tendon tears and entrapment (from lateral wall blow-out), sural nerve injury, Achilles tendon pathology, subtalar joint cartilage loss, bone marrow edema, and early post-traumatic arthritis changes. MRI is also the diagnostic modality of choice when symptoms persist after radiographic fracture healing, to identify the source of ongoing pain.
Treatment Options
Non-Surgical Management (Sanders Type I, Selected Extra-Articular)
Non-displaced fractures (Sanders Type I) and most extra-articular fractures are managed non-surgically with strict non-weight-bearing in a posterior splint or CAM boot for 6 to 10 weeks, followed by gradual weight bearing and physical therapy. Non-surgical management avoids the wound complications of surgery but does not address articular congruency in displaced intra-articular fractures. Even with perfect conservative management, Sanders Type I fractures can develop post-traumatic arthritis if the initial articular surface disruption was not fully appreciated on CT.
ORIF with Calcaneal Plate — Sanders Type II and III
Open reduction and internal fixation (ORIF) via the extensile lateral approach — a large L-shaped incision over the lateral heel — is the gold standard for displaced Sanders Type II and III intra-articular fractures when soft tissue conditions allow. The surgeon directly visualizes and reduces the articular fragments of the posterior facet, holds them with provisional K-wires, and then applies a low-profile calcaneal plate with multiple screws. Timing is critical: surgery before 10 days post-injury, before soft tissue swelling resolves, carries a dramatically increased wound dehiscence risk of up to 25%. Surgeons wait for the "skin wrinkling sign" — the return of skin wrinkles over the lateral heel indicating edema resolution — typically at 10 to 21 days post-injury. Minimally invasive percutaneous techniques (through small stab incisions using fluoroscopic guidance) have been developed to reduce wound complication rates in high-risk patients.
Primary Subtalar Fusion — Sanders Type IV
For Sanders Type IV severely comminuted fractures where the posterior facet is destroyed beyond anatomic reconstruction, primary subtalar fusion is the treatment of choice. Rather than attempting futile articular repair, the surgeon reduces calcaneal height and alignment, grafts any bony void, and fuses the subtalar joint with a large-diameter screw through the heel (a "hindfoot nail" or subtalar fusion screw). Recovery from primary subtalar fusion requires 10 to 12 weeks non-weight-bearing and 6 to 12 months total recovery. Although fusion eliminates the painful joint motion, it permanently restricts hindfoot inversion and eversion, alters gait mechanics, and increases stress on adjacent joints.
Late Subtalar Fusion — Post-Traumatic Arthritis Salvage
The most common late complication of displaced intra-articular calcaneus fractures — regardless of whether initial treatment was surgical or non-surgical — is post-traumatic subtalar arthritis developing 2 to 5 years after injury. When arthritic pain becomes disabling and unresponsive to conservative management (orthotics, injections, physical therapy), late subtalar fusion is the definitive salvage procedure. This is a second major surgery years after the original accident, requiring another 10 to 12 weeks non-weight-bearing and significant recovery. The future need for late subtalar fusion is a major component of future damages in calcaneus fracture litigation and should be documented by the treating orthopedic surgeon in the permanence opinion.
Complications and Long-Term Disability
Calcaneus fractures are notorious for their complications and long-term morbidity. Each complication represents an additional element of damages in a personal injury case.
Post-Traumatic Subtalar Arthritis
The most significant and most common long-term complication. Articular cartilage destroyed by the fracture does not regenerate; bone surfaces grind against each other with every step, producing progressive hindfoot pain, stiffness, and loss of walking tolerance. Majority of Sanders II-III patients develop clinically significant subtalar arthritis within 5 years regardless of surgical or non-surgical treatment. Ultimate treatment is subtalar fusion — a second major surgery years after the accident.
Wound Healing Complications
The extensile lateral approach has a 5 to 25% wound dehiscence rate depending on patient risk factors including smoking, diabetes, obesity, and peripheral vascular disease. Wound breakdown can expose the calcaneal plate, requiring debridement, plastic surgery flap coverage, prolonged wound care, and sometimes hardware removal. Wound complications add weeks to months of additional treatment and disability and increase settlement value substantially.
Peroneal Tendon Injury and Impingement
Lateral wall blow-out — the lateral cortex of the calcaneus being pushed outward by the fracture — impinges the peroneal tendons (peroneus longus and brevis) as they pass behind the lateral malleolus. This can cause peroneal tendon entrapment within the fracture, longitudinal split tears of the peroneal tendons, or peroneal tendon subluxation over the lateral malleolus. Symptoms include lateral ankle pain, snapping, and weakness of foot eversion. Treatment may require arthroscopic or open tendon debridement, repair, or reconstruction.
Sural Nerve Injury
The sural nerve — which provides sensation to the lateral foot and fifth toe — passes directly over the lateral calcaneus and is at risk both from the fracture itself (stretch or laceration) and from the surgical approach. Sural nerve injury causes numbness, tingling, or burning pain along the lateral foot. Sural neuroma — a painful scar ball at the site of nerve injury — can cause debilitating neuropathic pain requiring surgical neuroma excision or nerve desensitization treatment.
Complex Regional Pain Syndrome (CRPS)
CRPS Type I (without identifiable nerve injury) or Type II (with documented nerve injury) can develop after calcaneus fracture, producing disproportionate burning pain, allodynia (pain from light touch), skin color and temperature changes, and autonomic instability in the affected foot. CRPS is diagnosed clinically and confirmed by three-phase bone scan showing characteristic uptake pattern. Treatment includes sympathetic nerve blocks, spinal cord stimulation, and pain management. CRPS cases carry among the highest values in personal injury litigation due to their devastating impact on quality of life.
Permanent Heel Deformity and Shoe Fitting Difficulties
Even after successful treatment, calcaneus fractures typically result in permanent widening and shortening of the heel due to lateral wall blow-out and calcaneal height loss. The widened heel no longer fits standard shoe widths, requiring custom-made or specially modified footwear. Many patients cannot wear dress shoes or work boots at all, requiring permanent accommodation. Fibular impingement — the widened calcaneus abutting the fibula bone — causes lateral ankle pain with weight bearing and may require surgical lateral wall decompression.
Long-Term Disability: Impact on Working New Yorkers
Calcaneus fractures cause profound and often permanent disability for workers who stand, walk, or climb as part of their occupation. Construction workers, nurses and nursing assistants, teachers, retail workers, warehouse employees, police officers, firefighters, and sanitation workers face the possibility of permanent disability or career change after a severe calcaneus fracture. The inability to stand for prolonged periods, walk on uneven terrain, climb ladders, or wear standard work boots constitutes permanent partial disability of the foot and ankle. A vocational rehabilitation expert who documents lost earning capacity — the difference between the plaintiff's pre-accident occupation and what they can earn post-injury — is an essential expert in these cases and can document economic damages of hundreds of thousands of dollars over a working lifetime.
Calcaneus Fracture Case Results
Results obtained for Long Island calcaneus fracture clients. Past results do not guarantee future outcomes.
Sanders Type III Calcaneus Fracture + Subtalar Fusion + CRPS
High-speed frontal collision on the LIE caused floor pan intrusion that drove the driver's right foot upward with extreme axial force, transmitting load through the foot and shattering the calcaneus in a comminuted Sanders Type III intra-articular fracture with total obliteration of the posterior subtalar facet. CT scan revealed three major fracture lines, Böhler's angle collapsed to 8 degrees (normal 25-40°), and significant lateral wall blow-out with peroneal tendon entrapment confirmed on MRI. ORIF was delayed 16 days for soft tissue stabilization. Postoperatively, the plaintiff developed complex regional pain syndrome (CRPS Type I) confirmed by three-phase bone scan, with allodynia, vasomotor instability, and disproportionate burning pain unresponsive to three lumbar sympathetic blocks. At 28 months, subtalar fusion was performed for post-traumatic arthritis with 80% joint space loss. Vocational rehabilitation expert documented permanent inability to return to construction work.
Bilateral Calcaneus Fractures + L1 Burst Fracture ("Don Juan" Pattern)
Plaintiff's vehicle struck a concrete median barrier at highway speed, producing severe axial loading through both lower extremities and the lumbar spine simultaneously — the classic "Don Juan" tripartite injury pattern. Bilateral calcaneus fractures were Sanders Type II on the left and Sanders III on the right, both requiring ORIF. Emergency spine imaging (ordered only after the plaintiff's attorney sent a spoliation letter) identified an L1 burst fracture with 40% vertebral body height loss, managed with percutaneous pedicle screw fixation. Plaintiff, a 38-year-old teacher, was non-weight-bearing for 18 weeks. Permanent partial disability of both feet and chronic lumbar pain prevented return to prolonged standing required for classroom teaching. Defense hired biomechanical expert to argue low-speed impact; plaintiff retained accident reconstruction expert who established delta-V of 32 mph.
Sanders Type II Calcaneus Fracture + ORIF + Post-Traumatic Subtalar Arthritis
Plaintiff's foot was positioned on the brake pedal at the moment of a rear-end collision at highway on-ramp speed. The sudden deceleration combined with active brake pressure transmitted axial load through the calcaneus, producing a Sanders Type II displaced intra-articular fracture with a single fracture line through the posterior facet and 15-degree Böhler's angle reduction. ORIF was performed via extensile lateral approach with calcaneal plate and six screws at day 14 post-injury. Recovery was complicated by wound dehiscence requiring split-thickness skin graft, adding 8 weeks of additional wound care. At 30 months, follow-up CT documented Grade 3 subtalar arthritic changes with significant subchondral sclerosis and marginal osteophyte formation, and subtalar fusion was recommended. Permanence opinion documented permanent consequential limitation satisfying §5102(d).
Calcaneus Tuberosity Avulsion + Achilles Tendon Disruption
Plaintiff's heel struck the vehicle floor pan directly during a T-bone collision, producing a calcaneal tuberosity avulsion fracture — a fragment of the posterior calcaneus was pulled off by the Achilles tendon insertion under the sudden eccentric loading of the impact. The avulsion fragment was displaced 2 cm superiorly and 8 mm posteriorly on lateral X-ray, requiring operative fixation with two cannulated screws and tension band wiring to restore Achilles tendon continuity. Plaintiff, a 52-year-old postal carrier, was non-weight-bearing for 12 weeks. At MMI, orthopedic examination documented diminished push-off strength, plantarflexion limited to 30 degrees (normal 50 degrees), and persistent pain with heel strike, supporting permanent consequential limitation.
Tongue-Type Calcaneus Fracture + Conservative Management + Peroneal Tendon Injury
Low-speed parking lot collision caused plaintiff's foot to brace against the firewall during emergency braking, producing a tongue-type calcaneus fracture (Essex-Lopresti tongue pattern — fracture line extending from the posterior facet to the posterior tuberosity) with acceptable Böhler's angle of 22 degrees. Conservative management with non-weight-bearing cast for 8 weeks was elected. Follow-up MRI identified a longitudinal split tear of the peroneus longus tendon secondary to lateral wall fracture displacement and peroneal groove impingement, requiring arthroscopic debridement at 5 months. Plaintiff reported persistent lateral heel pain and ankle instability at 18-month follow-up, with documented difficulty ambulating on uneven terrain.
Extra-Articular Calcaneus Fracture + Non-Surgical Management
Plaintiff was a pedestrian struck by a motor vehicle that mounted the curb, sustaining an axial loading injury from the fall to pavement that produced an extra-articular calcaneus fracture (anterior process fracture involving the calcaneocuboid joint but not the subtalar facets). CT confirmed the fracture was Sanders Type I with no significant displacement and intact Böhler's angle. Conservative management with a walking boot for 10 weeks resulted in radiographic healing, but plaintiff reported persistent calcaneocuboid joint pain and difficulty with prolonged walking at 14-month follow-up. Treating podiatrist documented objective tenderness at the calcaneocuboid joint and reduced walking tolerance, supporting serious injury threshold under §5102(d) significant limitation of use.
New York Personal Injury Law and Calcaneus Fractures
New York Insurance Law §5102(d): The Serious Injury Threshold
New York is a no-fault insurance state. Under Insurance Law §5102(d), a car accident victim can only sue the at-fault driver for pain and suffering if they have sustained a "serious injury" as defined by the statute. A displaced intra-articular calcaneus fracture — particularly one classified as Sanders Type II, III, or IV — qualifies as a serious injury under multiple categories simultaneously: (1) fracture (a calcaneus fracture is per se a "fracture" within the meaning of §5102(d), satisfying the threshold without further proof); (2) permanent consequential limitation of use of a body organ or member (post-traumatic subtalar arthritis causing permanent restriction of subtalar motion and inability to walk on uneven terrain); and (3) significant limitation of use of a body function or system (documented reduction in subtalar range of motion, walking tolerance, and functional capacity). Even extra-articular calcaneus fractures qualify under the "fracture" category as long as causation is established. Our experienced Long Island car accident lawyer team will ensure your calcaneus fracture is properly documented to satisfy the threshold and maximize your recovery.
No-Fault Benefits and Medical Payment
Under New York's no-fault system, your own automobile insurance pays for your medical treatment and lost wages regardless of fault, up to the mandatory $50,000 in Personal Injury Protection (PIP) benefits. For a calcaneus fracture requiring ORIF surgery, the surgical costs alone can exceed $50,000 — meaning no-fault benefits may be exhausted before completion of treatment. If you have additional no-fault coverage (Supplemental SUM or excess PIP), coordinate with your attorney to ensure all available coverage is utilized. After no-fault is exhausted, health insurance becomes the primary payer, and your attorney will handle any health insurance liens at settlement. Do not make any recorded statements to the at-fault driver's insurance company before retaining counsel.
Statutes of Limitations and Filing Deadlines
New York personal injury claims must be commenced within 3 years of the accident date under CPLR §214. No-fault benefit applications must be submitted within 30 days of the accident. If a government entity is involved — a New York City bus, MTA bus, Nassau County vehicle, Suffolk County vehicle, NYSDOT truck, LIRR vehicle, school bus, or police car — a Notice of Claim must be filed within 90 days of the accident under General Municipal Law §50-e. Missing the 90-day Notice of Claim deadline is typically fatal to a claim against a government entity. Do not assume you have time to wait — retain counsel immediately after a calcaneus fracture diagnosis.

How to Pursue a Calcaneus Fracture Claim in New York
Five essential steps from accident to maximum recovery
Seek Emergency Evaluation and Obtain Complete Calcaneus Imaging
After a car accident involving floor pan intrusion, foot pain, heel pain, inability to bear weight, or visible deformity of the foot, go immediately to an emergency room. The standard calcaneus imaging series includes AP, lateral, and Harris heel (axial) views of the foot plus Broden views to evaluate the subtalar joint facets. Critically, you must demand a CT scan of the calcaneus with sagittal and axial reconstructions — plain X-rays alone are insufficient to classify the fracture, determine articular involvement, or plan surgery. The CT is mandatory for Sanders classification, which will drive all subsequent treatment decisions and will be one of the most important evidence documents in your legal case. Tell the emergency physician exactly how the injury occurred: floor pan intrusion, foot on brake pedal at impact, foot braced against firewall, or fall from height following collision. If both heels hurt, bilateral calcaneus fractures must be imaged. If a bilateral calcaneus fracture is diagnosed, insist on lumbar spine imaging to rule out the 'Don Juan' pattern of simultaneous lumbar burst fracture. Request copies of all imaging including the CT scan on disc before leaving the hospital.
Follow Up With a Foot and Ankle Orthopedic Surgeon for Classification and Surgical Planning
Emergency care stabilizes the acute fracture and manages compartment syndrome if present — a true surgical emergency. Within 5 to 7 days, follow up with an orthopedic surgeon specializing in foot and ankle surgery for definitive fracture classification and surgical planning. The surgeon will review your CT scan, classify the fracture using the Sanders system (Type I through IV), and determine surgical versus non-surgical management. For Sanders Type II and III fractures requiring ORIF, timing is critical: the 'skin wrinkling sign' — return of skin wrinkles over the lateral heel indicating resolution of swelling — is the clinical indicator that soft tissue is ready for surgery, typically occurring at 10 to 21 days post-injury. Surgery performed before soft tissue is ready carries a dramatically increased wound dehiscence and infection risk. For Sanders Type IV severely comminuted fractures, the surgeon may recommend primary subtalar fusion rather than ORIF. Your attorney should retain a biomechanical expert to document the floor pan intrusion mechanism and axial loading force transmitted to the calcaneus — this establishes causation and counters any defense argument that the impact was low-energy.
Complete Surgical Rehabilitation and Monitor for Complications
Post-operative rehabilitation for ORIF calcaneus fractures is a prolonged process. The standard protocol involves: non-weight-bearing in a well-padded posterior splint for 2 to 3 weeks until wound healing is confirmed; transition to a CAM boot; progressive range of motion exercises for the subtalar and ankle joints; and gradual weight bearing beginning at 10 to 12 weeks if CT scan confirms fracture healing. Attend every follow-up appointment and physical therapy session — gaps in treatment create defense arguments of non-serious injury. Monitor vigilantly for the most significant complications: wound dehiscence and infection (5-25% of extensile lateral approach ORIF cases — may require debridement, flap coverage, or hardware removal); peroneal tendon entrapment or subluxation from lateral wall blow-out (causing lateral ankle pain and snapping requiring surgical release); sural nerve injury (causing lateral foot numbness, paresthesias, or neuroma pain); fibular impingement from calcaneal widening; complex regional pain syndrome (CRPS — disproportionate burning pain, allodynia, vasomotor changes, confirmed by three-phase bone scan, treated with sympathetic blocks); and post-traumatic subtalar arthritis (progressive hindfoot pain developing over 2 to 5 years, the most common long-term complication). If your heel continues to hurt after fracture healing, insist on standing CT or weight-bearing X-rays to document early arthritic changes.
Obtain a Permanence Opinion Documenting Subtalar Arthritis and Functional Limitations
At maximum medical improvement — typically 18 to 24 months post-injury for calcaneus fractures — obtain a permanence opinion letter from your treating orthopedic surgeon documenting: (1) the calcaneus fracture confirmed on imaging with Sanders classification and Böhler's angle measurement; (2) causal relationship to the car accident mechanism (floor pan intrusion, axial loading); (3) all surgical procedures including ORIF with plate and screws, wound procedures, peroneal tendon surgery, or subtalar fusion; (4) subtalar joint range of motion measurements (normal subtalar inversion 20 degrees, eversion 10 degrees) compared to the contralateral foot; (5) standing CT or weight-bearing X-ray evidence of post-traumatic subtalar arthritis including joint space narrowing, subchondral sclerosis, and osteophyte formation; (6) calcaneal width measurement documenting permanent widening or shortening; (7) any associated injuries including sural nerve injury, peroneal tendon pathology, or CRPS; and (8) future medical needs including hardware removal, subtalar fusion, or CRPS treatment. Subtalar range of motion measurement is as critical to calcaneus fracture cases as ankle range of motion is to ankle fracture cases — these objective measurements satisfy the §5102(d) significant limitation of use and permanent consequential limitation categories.
Retain a Long Island Calcaneus Fracture Attorney and File Within All Deadlines
New York personal injury claims must be filed within 3 years of the accident date under CPLR §214. No-fault benefits must be applied for within 30 days of the accident. If a government vehicle was involved — a municipal bus, MTA bus, sanitation truck, LIRR vehicle, NYSDOT vehicle, or police car — a Notice of Claim under General Municipal Law §50-e must be filed within 90 days. Do not delay retaining counsel. A Long Island calcaneus fracture attorney experienced in §5102(d) threshold litigation will: immediately send preservation letters to prevent destruction of surveillance video (which is overwritten within 24-72 hours), EDR/black box data, and the defendant's vehicle; file the no-fault application; retain a biomechanical expert to document floor pan intrusion and axial load calculation; coordinate with your orthopedic surgeon on Sanders classification documentation, Böhler's angle measurement, subtalar arthritis imaging, and permanence opinion; retain a vocational rehabilitation expert if you perform physical labor and cannot return to your occupation; and handle all insurance communications while you focus on recovery. Calcaneus fracture cases with ORIF, subtalar fusion, CRPS, bilateral fractures, or associated lumbar spine injury are complex litigation requiring early and experienced legal representation.
