Injury Mechanics

How Broken Bones Happen in Car Accidents

Car accident fractures result from the sudden, violent transfer of kinetic energy to the human body during a collision. When two vehicles collide, the occupants’ bodies continue moving at the pre-impact speed until restrained by a seatbelt, airbag, or the vehicle interior itself. The forces involved in even moderate-speed crashes far exceed the load-bearing capacity of many bones — producing fractures that range from simple breaks requiring casting to comminuted injuries demanding complex orthopedic surgery.

The specific mechanism depends on the crash type and the occupant’s position. In rear-end collisions — the most common crash type on Long Island roads — the victim’s body is driven forward and then snapped back; the wrists and arms are often fractured as the driver grips the steering wheel or braces on the dashboard, and spinal compression fractures occur from the axial load of the jolt. Our rear-end accident lawyers handle the full spectrum of fracture injuries from these collisions.

In head-on collisions, the compressive force along the vehicle’s axis drives the lower extremities into the dashboard and floor, producing femur (thighbone) fractures, tibia and fibula fractures, and ankle fractures. The steering wheel and airbag generate chest loading that fractures ribs and the clavicle. T-bone and side-impact crashes are particularly dangerous for hip and pelvis fractures: the door intrudes into the occupant space, applying direct lateral force to the hip joint and acetabulum. Rollover accidents produce complex multi-fracture patterns as the body impacts multiple surfaces at varying angles during repeated vehicle rotation.

High-speed crashes produce more severe fractures, but low-speed collisions should not be underestimated. Even a 25 mph rear-end impact can generate forces exceeding the fracture threshold for brittle bones — particularly in older adults or those with osteoporosis. Insurance companies argue that low property damage means low injury force, but this conflates vehicle stiffness with occupant biomechanics. Our firm uses accident reconstruction experts to quantify occupant forces independently of vehicle damage. See our car accident lawyer page for a comprehensive Long Island overview.

Types of Fractures in Car Accident Cases

Car accidents produce a wide spectrum of fractures depending on the crash mechanism and the bones involved. Arm and wrist fractures result from the bracing-for-impact mechanism — drivers and passengers extend their arms to brace on the steering wheel or dashboard, transmitting axial load up the forearm and exceeding the fracture threshold of the distal radius. ORIF with plates and screws is frequently required for displaced or intra-articular wrist fractures.

Femur fractures are among the most severe in car accident cases: the femur is the strongest bone in the body, and fracturing it requires enormous force. Head-on and rear-end collisions drive the knee into the dashboard, producing mid-shaft or distal femur fractures that universally require hospitalization and intramedullary nailing or ORIF. Rib fractures result from seatbelt loading, airbag compression, and steering wheel impact; multiple rib fractures can produce life-threatening flail chest, while single rib fractures cause debilitating pain and limited activity for weeks.

Hip and pelvis fractures typically result from door intrusion in T-bone crashes, with the lateral impact driving the femur into the acetabulum. Acetabular fractures frequently require total hip replacement and carry significant lifetime post-traumatic arthritis risk. Spinal fractures occur most often at the thoracolumbar junction (T11-L2): compression fractures from axial loading, burst fractures from extreme compression, and flexion-distraction fractures from lap belt mechanisms in rollovers. Spinal fractures may threaten the spinal cord and require immediate surgical evaluation. For a detailed discussion of spinal injury claims, see our back injury lawyer page.

Clavicle fractures result from seatbelt loading and airbag deployment; they commonly require surgical fixation and produce prolonged shoulder dysfunction. Facial and orbital fractures occur from direct impact with the steering wheel, airbag, or side window. Ankle fractures (trimalleolar, bimalleolar) result from braced-foot mechanisms or floorboard intrusion and frequently require ORIF with prolonged non-weight-bearing status.

Fracture Severity and Your Legal Claim

Not all fractures are equal in medical complexity or legal claim value. Simple (closed) fractures involve a clean break managed with casting or non-surgical reduction; recovery is typically 6 to 12 weeks. These meet the §5102(d) threshold but carry more modest damages. Compound (open) fractures involve bone penetrating the skin and require emergency surgical washout, fixation, and IV antibiotic therapy — dramatically increasing both treatment costs and damages for pain, suffering, and infection risk.

Comminuted fractures are shattered into three or more fragments and almost always require ORIF with plates, screws, rods, or intramedullary nails. Recovery runs 12 to 24 months, and the risk of post-traumatic arthritis, hardware failure, and malunion is elevated. Growth plate (Salter-Harris) fractures in children can disrupt bone development, producing limb length discrepancy or angular deformity requiring long-term monitoring. ORIF surgery produces detailed operative reports — implant records, fracture pattern documentation, surgical complications — that our firm uses to quantify damages and document future hardware removal costs.

New York’s Serious Injury Threshold and Fractures

New York is a no-fault state: victims first seek PIP benefits from their own insurer for medical expenses and lost wages. To pursue a pain and suffering lawsuit against the at-fault driver, the victim must prove a “serious injury” under Insurance Law §5102(d).

The statute’s serious injury categories include several that require proof of permanence or significant limitation — but “fracture” is not one of them. It is objective and automatic: a fracture documented by imaging (X-ray, CT scan) and confirmed by a treating physician satisfies the threshold as a matter of law, with no proof of permanence, significant limitation, or 90-day disability required. A wrist fracture that heals completely in 8 weeks still satisfies §5102(d). Insurance companies cannot defeat the threshold by arguing the fracture healed well — once the fracture is documented, the threshold is met. For a complete car accident overview including all threshold categories, see our Long Island car accident lawyer page.

What Damages Can Fracture Victims Recover?

Economic damages include all measurable financial losses: ER care, hospitalization, orthopedic surgery and anesthesia, post-surgical imaging, physical therapy, medical devices, future hardware removal or joint replacement surgery, future physical therapy, and lost wages. Reduced earning capacity matters significantly for manual laborers, construction workers, and athletes whose fractures impose permanent occupational restrictions.

Non-economic damages cover pain and suffering, loss of enjoyment of life, emotional distress, and permanent impairment. New York does not cap non-economic damages. Future medical expenses are critical: post-traumatic arthritis from intra-articular fractures, hardware complications (plate loosening, screw breakage), and malunion may require joint replacement or corrective surgery decades after the original injury. Our firm retains orthopedic experts to project lifetime complication costs and build the complete damages record needed to maximize recovery. Under CPLR §1411, comparative fault reduces but does not eliminate recovery — see our car accident lawyer page for a full discussion.

Proving Fault and Comparative Negligence

While the fracture threshold is often straightforward once medical records are in hand, insurance companies fight damages hard when threshold is conceded. Building a strong liability record is foundational to maximizing recovery. Key evidence includes: the police MV-104 accident report identifying contributing factors and VTL violations; VTL violations establishing negligence per se, including VTL §1180 (speeding), VTL §1141 (failure to yield), and VTL §1163 (improper turn); EDR/black box data recording pre-crash speed and brake application; and witness statements and accident reconstruction for disputed liability.

Under CPLR §1411, recovery is reduced but not eliminated by your own contributory negligence. Even if you were speeding or inattentive, you can still recover a proportionate share of your damages. VTL §1229-c permits defendants to raise seatbelt non-use to mitigate damages; our firm addresses this proactively with biomechanical expert analysis. The defense will attempt to inflate your fault allocation — our firm builds the evidence record to accurately and favorably represent fault.

Statute of Limitations for Broken Bone Car Accident Claims

Under CPLR §214, personal injury claims for broken bones must be filed within three years of the accident. A lawsuit filed one day late is permanently barred. Do not rely on this window as an excuse for delay — EDR data may be overwritten in vehicle repairs, witnesses’ memories fade, and medical records from smaller facilities are sometimes unavailable years after treatment.

Government vehicle claims carry a critical 90-day deadline: if the at-fault vehicle was owned or operated by a municipal, county, or state government entity, you must file a Notice of Claim under General Municipal Law §50-e within 90 days of the accident. Missing this deadline permanently bars the claim. Contact our Long Island car accident attorneys immediately to identify all applicable deadlines and preserve your rights.
