Foot drop cases usually turn on two questions: when the deficit was first documented, and what was done once it was. I review foot drop and peroneal nerve injury claims for plaintiff and defense counsel as a board-certified foot and ankle surgeon in active practice, and I am direct about where a podiatric opinion carries weight and where you need a second expert.

Where these cases come from

• Positioning and compression during surgery or anesthesia — common peroneal nerve compression at the fibular head from prolonged lateral positioning, stirrups, or an unpadded leg holder
• Cast, splint, brace and boot pressure — a device applied tightly over the fibular neck, and a reported complaint that was not acted on
• Knee and hip arthroplasty, knee arthroscopy and knee dislocation — traction or direct injury to the common peroneal nerve
• Proximal fibula and fibular head fracture
• Delayed recognition of leg compartment syndrome
• Injection injury
• Entrapment — common peroneal nerve at the fibular neck, deep peroneal nerve at the ankle
• L5 radiculopathy — clinically the most common non-surgical cause of foot drop, and the one most often confused with a peripheral nerve lesion

Where my opinion stops

I am a foot and ankle surgeon. I can speak to peripheral nerve anatomy below the knee, to the foot and ankle consequences of a dropped foot, to bracing and tendon-transfer management, and to whether the foot and ankle care met the standard. If the case turns on lumbar spine surgery, on the conduct of an arthroplasty, or on anesthesia positioning protocol, you need an expert in that specialty as well — and I will tell you so at the conflict check, not after you have paid for a report.

What the record has to show

• A baseline motor exam. The most valuable document in these files, and the one most often missing. Without a documented pre-procedure dorsiflexion and eversion strength, the causation argument narrows to timing.
• Timing of onset. Nursing notes and therapy notes usually date the deficit more precisely than the physician notes do.
• Complaints and what followed. A documented complaint of numbness, burning or a tight cast, and what happened in the hours after it was made.
• Electrodiagnostic studies, and when they were run. A study performed in the first days after injury will not yet show denervation changes, and that timing is routinely misread as evidence that no injury occurred.
• Management. Whether an ankle-foot orthosis was provided and when, therapy, and whether nerve decompression or tendon transfer was ever considered.

Damages, medically

A permanent foot drop is not a nuisance injury. It means brace dependence, an altered gait, a measurably higher fall risk, and over time a fixed equinus contracture if the ankle is not managed. Tendon transfer is a salvage procedure, not a restoration of normal function. Where the deficit is incomplete or still recovering, I will say that too — the recovery curve for a compression neurapraxia is very different from that of a transected nerve, and a life-care plan built on the wrong one does not survive cross-examination.
