Understanding Pre-Existing Injuries in New York Personal Injury Claims: What You Need to Know

When pursuing a personal injury claim in New York, one of the most challenging obstacles plaintiffs face is addressing pre-existing medical conditions. The landmark case of Hoffner v Nelson, 2019 NY Slip Op 0078 (4th Dept. 2019), provides a stark reminder of how critical transparency about medical history can be to the success of a personal injury case.

The Hoffner v Nelson Case: A Cautionary Tale

Hoffner v Nelson demonstrates how undisclosed pre-existing conditions can completely derail a personal injury claim. In this case, the plaintiff’s failure to disclose a history of leg pain related to pre-existing back problems proved fatal to her lawsuit.

The Court of Appeals noted: “It is well established that a defendant may overcome an allegation of serious injury by demonstrating that the plaintiff’s injury was preexisting.” Although two expert witnesses testified that the plaintiff’s leg pain and weakness were causally related to the accident, the jury was not required to accept their opinions when facts disclosed during cross-examination contradicted the foundation of their testimony.

How Pre-Existing Conditions Affect Personal Injury Claims in New York

The Legal Standard

Under New York law, defendants can successfully defend against serious injury claims by proving that the plaintiff’s injuries were pre-existing rather than caused by the accident in question. This doesn’t mean that people with pre-existing conditions cannot recover damages, but it does mean that transparency and proper medical documentation are crucial.

The Aggravation Doctrine

New York recognizes that accidents can aggravate pre-existing conditions. Under the “eggshell plaintiff” rule, defendants must take plaintiffs as they find them. If an accident worsens a pre-existing condition, the defendant may still be liable for the additional harm caused. However, plaintiffs must be able to prove:

• The pre-existing condition existed before the accident
• The accident aggravated or worsened the condition
• The extent of the aggravation caused by the accident
• The additional damages attributable to the aggravation

Documentation Requirements

Successful personal injury claims involving pre-existing conditions require meticulous documentation:

• Complete medical records from before the accident
• Detailed records of treatment after the accident
• Expert medical testimony distinguishing between pre-existing conditions and accident-related injuries
• Honest disclosure of all relevant medical history

Common Types of Pre-Existing Conditions in New York Injury Cases

Spinal Conditions

Back and neck injuries are among the most common claims in personal injury cases. Pre-existing conditions such as:

• Degenerative disc disease
• Previous herniated discs
• Arthritis
• Prior spinal surgeries

These conditions require careful analysis to distinguish between pre-existing symptoms and accident-related aggravation.

Joint Problems

Many people suffer from pre-existing joint issues that can be aggravated by accidents:

• Previous knee injuries
• Shoulder problems from repetitive use
• Hip arthritis
• Previous fractures or dislocations

Neurological Conditions

Pre-existing neurological conditions can complicate injury claims:

• Previous traumatic brain injuries
• Chronic headaches or migraines
• Nerve damage from prior injuries
• Seizure disorders

The Importance of Full Disclosure

Why Honesty Matters

The Hoffner case illustrates why complete honesty about medical history is essential. The plaintiff’s surgeon testified that the undisclosed history of leg pain related to pre-existing back problems would have been important information. This non-disclosure undermined the credibility of the plaintiff’s entire case.

Consequences of Non-Disclosure

Failing to disclose pre-existing conditions can result in:

• Dismissal of the entire lawsuit
• Loss of credibility with the jury
• Inability to recover any damages
• Potential claims for fraud or misrepresentation
• Sanctions against the plaintiff’s attorney

Working with Your Attorney

When consulting with a personal injury attorney, it’s crucial to:

• Provide complete medical history
• Disclose all prior injuries, regardless of how minor
• Share all relevant medical records
• Be honest about ongoing symptoms or treatments
• Discuss any concerns about pre-existing conditions

Strategies for Handling Pre-Existing Conditions

Medical Expert Testimony

Successful cases involving pre-existing conditions typically require qualified medical experts who can:

• Review all medical records thoroughly
• Distinguish between pre-existing conditions and new injuries
• Explain the aggravation of pre-existing conditions
• Provide clear testimony about causation

Diagnostic Testing

Modern diagnostic tools can help establish the extent of pre-existing conditions versus new injuries:

• MRI imaging comparing before and after the accident
• CT scans showing new damage
• X-rays documenting progression of conditions
• Functional capacity evaluations

Documentation Timeline

Creating a clear timeline of medical treatment helps establish:

• The plaintiff’s condition before the accident
• Immediate symptoms following the accident
• Progression of symptoms over time
• Response to various treatments

Special Considerations for Different Types of Accidents

Motor Vehicle Accidents

Car accidents often involve complex pre-existing condition issues because:

• Many people have prior back or neck problems
• Impact forces can aggravate existing spinal conditions
• Insurance companies aggressively investigate medical histories

Slip and Fall Cases

Premises liability claims frequently involve:

• Pre-existing orthopedic conditions
• Balance or mobility issues
• Prior falls or injuries
• Age-related conditions that affect recovery

Workplace Injuries

Workers’ compensation cases must address:

• Repetitive stress injuries that developed over time
• Previous workplace injuries
• Age-related wear and tear
• Non-work related medical conditions

Frequently Asked Questions About Pre-Existing Conditions

Can I still recover damages if I have pre-existing injuries?

Yes, you may still recover damages even with pre-existing conditions, provided you can prove that the accident aggravated your condition or caused new injuries. The key is honest disclosure and proper medical documentation of the aggravation.

What happens if I forgot to mention a previous injury?

If you genuinely forgot about a minor previous injury, you should immediately inform your attorney when you remember. However, if the omission appears intentional or involves significant medical history, it could seriously damage your case.

How do insurance companies investigate pre-existing conditions?

Insurance companies will thoroughly review your medical records, often going back many years. They may also conduct surveillance, request independent medical examinations, and interview healthcare providers to establish your pre-accident condition.

Should I mention minor aches and pains from years ago?

Yes, you should disclose all relevant medical history to your attorney, even minor issues. Your lawyer can help determine what information is relevant and how to present it in the best light for your case.

Can pre-existing conditions completely bar recovery?

While pre-existing conditions don’t automatically bar recovery, they can significantly complicate your case. In extreme situations, like the Hoffner case, non-disclosure of significant pre-existing conditions can result in a complete loss of the case.
