Implication

Case report demonstrates proximal tibial neuropathy mimicking tarsal tunnel syndrome in a rock climber, highlighting climbing biomechanics as an emerging cause of nerve injury.

Key Points

To describe an atypical case of proximal tibial neuropathy resembling tarsal tunnel syndrome in a recreational indoor rock climber.
Clinical evaluation of a 36-year-old male indoor rock climber presenting with progressive medial plantar paresthesia and left hallux flexion weakness.
Comprehensive diagnostic workup utilizing electromyography, nerve conduction studies, and high-resolution neuromuscular MRI extending from the mid-thigh through the foot.
Electrodiagnostic studies revealed active, widespread denervation in proximal tibial-innervated muscles rather than isolated distal nerve entrapment.
Neuromuscular MRI demonstrated continuous, diffuse T2 hyperintensity along the sciatic nerve from the mid-thigh down through the tibial nerve without evidence of focal compressive mass.
Clinical presentation exhibited a relapsing-remitting course closely aligned with frequency and intensity of climbing activity.
