Tarsal tunnel syndrome is a complex of symptoms resulting from the compression of the posterior tibial nerve or its branches. Many studies have done on etiologic agents. We reported two cases of tarsal tunnel syndrome secondary to the varicosis of posterior tibial vein. Symptoms were relieved after excision of the varicosis, neurolysis and reposition of posterior tibial nerve.

Management of postoperative tarsal tunnel syndrome is a perplexing problem to the surgeons. Autogenous vein wrapping graft is a effective method to decompress the tarsal tunnel. We treated 2 cases of postoperative tarsal tunnel syndrome with autogenous saphenous vein wrapping graft technique, and could get good results. Autogenous vein wrapping graft seems to be a good technique for tarsal tunnel syndrome with severe adhesion, particularly after surgery, and postoperative nerve adhesion can be prevented.

Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve or its branches in the fibro-osseous tunnel beneath the flexor retinaculum. This pathology is associated with multiple etiologies, including trauma, space-occupying lesions, and impaired biomechanics. We report a case of tarsal tunnel syndrome associated with gout tophi in a patient with untreated gout along with a review of the relevant literature on tarsal tunnel syndrome.

Tarsal tunnel syndrome is defined as a compressive neuropathy of the posterior tibial nerve in the tarsal canal. Schwannoma is a benign tumor that arises from the peripheral nerve sheath. It presents as a discrete, often tender, and palpable nodule associated with neurogenic pain or paresthesia when compressed or traumatized. The growth rate is usually slow, and these lesions seldom exceed 2 cm in diameter. In addition, local recurrence occurs less than 5%. We report on a case of tarsal tunnel syndrome caused by a large recurred space-occupying lesion measuring 4.3x2.7x2.7 cm3.

OBJECTIVE: To demonstrate the bifurcation pattern of the tibial nerve and its branches. METHODS: Eleven legs of seven fresh cadavers were dissected. The reference line for the bifurcation point of tibial nerve branches was an imaginary horizontal line passing the tip of the medial malleolus. The distances between the reference line and the bifurcation points were measured. The bifurcation branching patterns were categorized as type I, the pattern in which the medial calcaneal nerve (MCN) branched most proximally; type II, the pattern in which the three branches occurred at the same point; and type III, in which MCN branched most distally. RESULTS: There were seven cases (64%) of type I, three cases (27%) of type III, and one case (9%) of type II. The median MCN branching point was 0.2 cm (range, -1 to 3 cm). The median bifurcation points of the lateral plantar nerves and inferior calcaneal nerves was -0.6 cm (range, -1.5 to 1 cm) and -2.5 cm (range, -3.5 to -1 cm), respectively. CONCLUSION: MCN originated from the tibial nerve in most cases, and plantar nerves were bifurcated below the medial malleolus. In all cases, inferior calcaneal nerves originated from the lateral plantar nerve. These anatomical findings could be useful for performing procedures, such as nerve block or electrophysiologic studies.

Tarsal tunnel syndrome caused by space occupying lesion is unusual but it rarely occur by ganglion which is presented below the flexor retinaculum due to compression neuropathy of posterior tibial nerve and its branches. The object of the current study is to report our experience of surgical treatment about tarsal tunnel syndrome caused by the ganglion of flexor digitorum longus tendon sheath and multifocal myxoid degeneration of medial plantar nerve with a review of the literatures.

During routine dissection, additional muscular head of extensor digitorum brevis muscle attaching to the third toe and accessory muscle perforated by the branch of the deep peroneal nerve were observed in the right foot of a 71-year-old male cadaver. The additional muscular head originated from the dorsal surface of cuboid bone, and ran parallel with the third tendon of the extensor digitorum brevis muscle. It was conjoined with the third tendon of extensor digitorum brevis at the middle of its course. The accessory muscle was a small muscle which was covered with the muscle belly of the extensor hallucis brevis muscle. It originated from the dorsal surface of the calcaneus, and inserted to the lateral one-third of transverse retinacular band. These two variants were innervated by the branches of deep peroneal nerve. The branches of deep peroneal nerve were compressed under the tendon of extensor hallucis brevis and around the site where the nerve branch perforated the small muscle. The clinical significances of these variations and tendon of extensor hallucis brevis muscle were discussed.

Tarsal tunnel syndrom is characterized by pain, paresthesias in the foot in either the entire distribution of the tibial nerve or the distribution of one or two of its major branches and caused by compression of the posterior tibial nerve as it passes posterior and inferior to the medial malleolus. This syndrome is not recognized as readily as its counterpart in the upper extremity, the carpal tunnel syndrome. Anatomically unlike the transv erse carpal ligament the laciniate ligament(flexor retinaculum) has several deep fibrous septa which blend with the periosteum covering the medial side of the calcaneus. The neurovascular bundle in the tarsal tunnel is often attached to some of these septa, rendering itself more liable to minor degrees of traction on movements of the foot. A case of tarsal tunnel syndrome, the patient 24 years old policeman, treated succesfully with surgical release of laciniate ligament is reported.

Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the posterior tibial nerve or one of its branches within the tarsal tunnel, and is often caused by ganglia, lipoma, accessory muscles, varicosities, neural tumours, trauma and systemic diseases. We have successfully treated a patient with tarsal tunnel syndrome which was associated with os sustentaculi.
