The MRI Says “Degenerative.” Did the Florida Crash Still Cause Your Injury?

The radiology report uses a word that insurance adjusters notice immediately: degenerative.

Maybe an MRI from years before the crash already showed disc narrowing, arthritis, a bulge, or a torn structure. Maybe there was no earlier scan, but the new report describes “chronic” changes. The insurer then moves from a medical description to a legal conclusion: the collision did not cause the injury.

Florida law does not make that leap. A person does not lose the right to recover merely because the body was not perfect before an accident. But a prior condition also does not automatically make every later symptom the defendant’s responsibility. The real question is what changed—and whether reliable evidence connects that change to the accident.

“Preexisting” can describe very different medical histories

Two people can receive the same “degenerative changes” notation and have very different claims.

One person may have been treating the same body part every month, reporting the same pain level, facing the same work restrictions, and considering the same surgery before the collision. Another may have an old imaging finding that never caused symptoms, required no treatment, and did not limit work or daily life until the crash. A third may have recurring but manageable symptoms that became constant, more severe, or neurologically different afterward.

Those histories should not be collapsed into one label. The first may present a difficult causation dispute. The second may involve the activation of a latent condition. The third may involve the aggravation of a symptomatic condition. In each situation, the investigation should compare the person’s actual condition and function before the incident with the medical course afterward.

That comparison is part of the larger causation analysis in a Florida car-accident claim. The question is not simply whether degeneration existed. It is whether the defendant’s conduct caused a new injury, activated a previously silent condition, aggravated an existing condition, or did none of those things.

Florida’s jury instruction does not treat a fragile plaintiff as a free pass

Florida’s current standard civil jury instructions address the aggravation or activation of an existing disease or physical defect. In substance, the jury is asked to determine what portion of the claimant’s condition resulted from the aggravation or activation. If the jury can separate the conditions, damages are limited to the portion caused by the incident. If the effects cannot be separated, or the condition cannot be said to have existed apart from the injury, the instruction permits the jury to consider the entire condition.

This is sometimes described as the “eggshell plaintiff” principle: a negligent person generally takes the injured person as that person was found. It does not mean the accident is deemed to have caused every medical problem. It means an unusual susceptibility does not excuse the harm that the accident actually caused.

The distinction is important. A collision might not have created spinal degeneration, yet it may have transformed an asymptomatic spine into a painful one. It might not have caused the original shoulder tear, yet it may have enlarged the tear or made previously tolerable limitations disabling. The compensable injury is the proven change, not the mere presence of an abnormal scan.

An accident plus an old condition is not proof of aggravation

Florida appellate law also supplies an equally important warning: aggravation must be established with evidence.

In State Farm Mutual Automobile Insurance Co. v. Davis, decided by Florida’s Fifth District Court of Appeal in 2022, the plaintiff had a substantial pre-crash treatment history involving her neck and back. Her medical witnesses attributed her injuries to the collision, while the defense expert said her complaints were unrelated to it. Neither side offered evidence that the crash had aggravated the prior conditions. The court held that aggravation was not something the jury could simply infer from the existence of a prior condition and a later crash.

The decision also addressed pleading. The Fifth District treated aggravation of a preexisting condition as special damages that had to be specifically claimed. Because the theory was neither properly pleaded nor supported by evidence in that case, the court reversed the judgment and excluded aggravation damages from the new trial it ordered.

That holding does not turn a prior diagnosis into a defense victory. It shows why the theory must be identified and developed. “The crash caused everything” and “the crash caused nothing” are not the only possibilities. If the truthful medical theory is aggravation, the pleadings, discovery, medical testimony, and damages presentation need to say so.

The before-and-after record is more useful than the word “degenerative”

A strong causation analysis begins before the accident date.

Prior records may show whether the same area was symptomatic, how often treatment occurred, what diagnoses were made, and whether surgery, injections, or restrictions had already been recommended. Pharmacy records can show whether pain medication was occasional or continuous. Employment records may document accommodations or missed time. Fitness, travel, household, and caregiving activities can help establish functional baseline when supported by reliable witnesses and records.

The post-accident record then needs the same level of detail. Did symptoms begin immediately, emerge gradually, or return after an unrelated event? Were they different in location, intensity, frequency, or type? Did numbness, weakness, headaches, instability, or reduced range of motion appear for the first time? Did the person require new treatment, stronger medication, injections, surgery, assistance at home, or time away from work?

Imaging matters, but it should be placed on a timeline. Comparing actual prior and current images can be more informative than comparing two written summaries. The age of a finding does not necessarily reveal when symptoms began, and a radiologist’s use of “chronic” does not resolve legal causation by itself. Treating physicians and qualified experts may need to explain whether the objective findings, mechanism of injury, symptom progression, examination results, and prior history fit a new injury or aggravation theory.

Tucker Law’s article on delayed car-accident symptoms discusses why the medical timeline matters when pain or neurological complaints are not fully apparent at the scene. A delayed symptom is not automatically unrelated, but the longer the gap, the more important careful documentation becomes.

Old records can help the claimant as much as the defense

People sometimes fear that disclosing earlier treatment will destroy the claim. Concealing it is usually far more damaging.

A prior record can establish that the claimant recovered, had reached a stable baseline, or had gone months or years without needing care. It can distinguish occasional stiffness from daily radicular pain. It may show that the earlier injury involved a different level of the spine, different symptoms, or different functional limitations. It can also reveal that a procedure now being blamed on the crash was already planned beforehand—which is precisely why the records must be assessed honestly.

In Snedegar v. Arnone, the Fourth District found a basis for allowing the jury to consider aggravation where the evidence included prior injuries and more recent symptoms that the accident could have worsened. The case illustrates that relevant evidence can emerge through either side’s proof. What matters is whether competent evidence supports the theory presented to the jury.

Credibility becomes central when medical history is disputed. Insurance applications, intake forms, deposition answers, prior claims, and recorded statements may all be compared. “I never had pain before” can become a damaging absolute if one record shows otherwise. “I had occasional low-back treatment, but this was the first time pain traveled into my leg” is more precise when true.

Before providing a statement to an insurer, it is worth understanding how early descriptions may later be used. Tucker Law’s guidance on recorded insurance statements explains why accuracy matters, while the firm’s overview of a Florida personal-injury deposition addresses sworn questioning later in the case.

The doctor’s opinion must address the real dispute

A medical opinion is more useful when it explains the reasoning rather than announcing a conclusion. The analysis may consider the force and direction of the event, the person’s immediate complaints, objective examination findings, prior imaging, changes on later imaging, treatment history, alternative causes, and whether the clinical course is consistent with trauma.

The terminology should also match the evidence. A new traumatic injury, an activation of a latent condition, a permanent aggravation, and a temporary exacerbation are not interchangeable descriptions. If symptoms returned to their former baseline after several weeks, the claimed damages may differ sharply from a condition that remained permanently worse.

Medical records should document function, not only pain scores. The inability to lift a child, drive for more than twenty minutes, perform overhead work, sleep through the night, or stand through a shift can help explain the practical difference between the pre-accident and post-accident condition. Family members, coworkers, and supervisors may supply relevant observations, but those accounts should align with the medical and documentary record.

Auto cases add Florida’s permanent-injury threshold

In many Florida motor-vehicle cases, proving that the crash aggravated a condition does not by itself establish entitlement to noneconomic damages. Florida Statute § 627.737 limits recovery of pain, suffering, mental anguish, and inconvenience unless the claimant proves one of the statutory threshold injuries, such as a permanent injury within a reasonable degree of medical probability, significant and permanent loss of an important bodily function, significant and permanent scarring or disfigurement, or death.

A temporary aggravation may support medical expenses or other economic damages caused by the crash while failing to satisfy that threshold. A permanent aggravation may present a different analysis. The medical evidence must address not only whether something changed, but also the expected duration and degree of that change.

This is one reason the word “degenerative” should neither end the inquiry nor be ignored. The law asks a more disciplined set of questions: What existed before? What changed after? What caused the change? Can the effects be separated? Is the change temporary or permanent? And what damages are supported by the evidence?

Build the comparison before memories and records disappear

Prior medical providers may retire, imaging systems may not retain studies indefinitely, and people’s recollection of their old symptoms becomes less precise over time. Requesting the relevant records and original imaging early allows doctors and counsel to compare rather than speculate. A short written chronology of prior treatment, symptom-free periods, the accident, new symptoms, and subsequent care can also help identify gaps that need explanation.

Florida’s general limitation period for many negligence claims is two years under Florida Statute § 95.11, although different claims and defendants can produce different deadlines. The evidentiary clock is often shorter.
