Purpose. Tarsal Tunnel Syndrome (TTS) was first reported by Keck and Lam separately in 1962. It has been regarded as the lower limb equivalent to Carpal Tunnel Syndrome (CTS). The gold standard of diagnosis proposed over the years is nerve conduction study (NCS). In reality, TTS is much harder to diagnose and treat compared to CTS. Signs and symptoms can be mimicked by other foot and ankle conditions. Our unit had not seen a single positive nerve conduction result of TTS in clinically suspicious cases. We have therefore audited our 10 year experience. Methods and Results. This is a retrospective audit. Patient list retrieved from
