Rare Common Peroneal Nerve Neuropraxia after Removal of Upper Tibial Pin Traction.

Common peroneal nerve (CPN) injury is an uncommon complication associated with skeletal traction. Neurological deficits occurring after removal of upper tibial pin traction (UTPT) are exceedingly rare and sparsely reported in the literature. A 27-year-old male sustained a closed left subtrochanteric femur fracture following a road traffic accident. Preoperative UTPT was applied with no immediate neurological deficit. UTPT was removed intraoperatively before definitive fixation. Postoperatively, the patient developed left-sided foot drop. Electromyography and nerve conduction velocity studies at 6 weeks demonstrated neuropraxia of the CPN. Although UTPT is considered a safe and effective method for temporary fracture stabilization, clinicians should be aware of the potential for rare traction-related nerve injuries. Early recognition, appropriate splintage, and rehabilitation can result in favorable outcomes.
