Tarsal tunnel syndrome with double causes (ganglion, tarsal coalition) evoked by ski boots. Case report.

We report a 19-year-old female with tarsal tunnel syndrome arising from a ganglion and a bony prominence from talocalcaneal coalition. However, in this case, tarsal tunnel syndrome was caused by ski boots compressing the tibial nerve within the tarsal tunnel. The patient was successfully treated by surgery. This is believed to be the first case with double causes (ganglion, tarsal coalition) evoked by trauma (skiing).
