Spine injury causation surgeon

Expert class library · Personal injury · Plaintiff side

An orthopedic spine surgeon or neurosurgeon, often the treating surgeon, who testifies that a crash or fall caused a disc herniation or other spinal injury and the surgery that followed. Courts admit causation opinions built on plausibility, timing and ruling out other causes, but they police the step that matters most in spine cases: accounting for degenerative disease and other accidents or injuries. A surgeon who relies on the timing of symptoms without addressing a prior trauma may be limited to saying the injury is consistent with the crash, and the defense is entitled to confront the surgeon with alternative causes.

What this expert is retained to answer

• Has the surgeon reviewed imaging and records from before the incident, and how do they distinguish acute from degenerative findings?
• Does the opinion rest on more than the timing of the patient's symptoms?
• How does the surgeon account for other accidents, assaults or injuries that could have caused the same condition?
• Is the surgeon offering a medical causation opinion, or a biomechanical opinion about crash forces they have not studied?
• Is the surgeon a treating physician or a retained expert, and was the causation opinion disclosed?

Methods

• Review of imaging such as MRI and CT, before and after the incident
• Clinical history, examination and temporal relationship
• Differential diagnosis of traumatic and degenerative causes
• Review of prior medical records, injuries and accidents
• Surgical findings and treatment planning

How the testimony is attacked

• Temporal relationship alone. Defendants argue that pain beginning after a crash does not prove the crash caused it. In Etherton v. Owners Insurance the Tenth Circuit upheld a physician's three-step method, which asked whether the injury was plausible, whether the timing fit, and whether something else was a more likely cause.
• Alternative causes not ruled out. A surgeon who ignores another plausible cause can be limited. In Castro v. Schlumberger Technology the Texas court upheld confining an orthopedic surgeon to testifying that a cervical herniation was consistent with the crash, because he had not accounted for a prior assault or the forces involved.
• Cross-examination on a second accident. Excluding evidence of another accident can be reversible error. In JLG Trucking v. Garza the Texas Supreme Court ordered a new trial because the jury never heard about a later collision and the plaintiff's orthopedic surgeon could not be cross-examined about it.
• Biomechanics outside the surgeon's field. Surgeons are challenged when they opine on crash forces, vehicle damage or how the collision happened, which may require biomechanical expertise.
• Degenerative disease. Most adults show degenerative disc changes on imaging, and defense experts argue the findings predate the incident.

What the public record shows

Courts have filed at least 61 opinions since 2015 that address this class of testimony under Daubert or Rule 702, as of October 4, 2026. Three that show how courts handle this class of testimony:

Under amended Rule 702

Since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.
