Tarsal tunnel syndrome (TTS) is elicited by compression of the tibial nerve in the tarsal tunnel. TTS in the absence of a lesion tends to be idiopathic, and most TTS is idiopathic. Patients complain of several plantar symptoms, and TTS affects their quality of life. The symptoms tend to worsen with walking, and ankle joint movement and arterial distortion may also be involved. Because TTS symptoms are similar to those of diabetic neuropathy and lumbar disease, clinical symptoms are diagnostically important. While magnetic resonance imaging reveals nerve compression, it is difficult to identify causative factors, and false-positive results are a concern. Wound-related complications after TTS surgery may be reduced by a zigzag skin incision. Surgery for carpal tunnel syndrome yields better outcomes and greater patient satisfaction than TTS surgery.
