Tarsal Tunnel Syndrome (TTS) is an entrapment neuropathy of tibial nerve which is compressed in the tarsal tunnel, an anatomic structure formed between bones (medial wall of calcaneus, talus and distal tibia) and flexor retinaculum. The cases are usually idiopathic whereas occasionally TTS occurs secondary to space occupying lesions such as ganglia, tumors, bony protrusions [1-8]. Tarsal coalition, a congenital disorder resulting in fibrous, cartilaginous or osseous union of tarsal bones is an uncommon cause of TTS [2,4,8]. We present a case with TTS due to talocalcaneal coalition in this report.
