Tarsal tunnel syndrome: an endoscopic approach with 4- to 28-month follow-up.

The authors have used instrumentation developed by Smith & Nephew Dyonics, Inc., designed for endoscopic carpal tunnel release (ECTRA) in the endoscopic treatment of tarsal tunnel syndrome. This new technique reduces trauma to the patient and decreases scar formation over the release site. These appear advantageous over the open surgical technique. A retrospective study was conducted with a resultant 89% success rate.
