Abstract

Tarsal tunnel syndrome (TTS) is classically a compressive neuropathy of the posterior tibial nerve beneath the flexor retinaculum, presenting with plantar foot pain and paresthesias. Standard surgical management of TTS involves release of the flexor retinaculum to decompress the nerve. We report a rare and unusual case of TTS in which the posterior tibial nerve was encased within a post-traumatic osseous tunnel accompanied by dense fibrotic tissue, representing an atypical and previously undescribed etiology of nerve entrapment. In this case, surgical decompression required a modified approach involving meticulous dissection of the tibial nerve from its encasement by heterotopic ossification and surrounding scar tissue.

Postoperatively, the patient endorsed complete resolution of his neuropathic pain symptoms and demonstrated a negative Tinel’s sign, consistent with successful and durable decompression. This case highlights the importance of recognizing post-traumatic anatomical variations, as well as the need for adaptable surgical techniques to effectively address these complex and uncommon presentations.
