Thirty patients with classical or definite rheumatoid disease (RD) with foot pain and radiologically demonstrated erosions were studied electrodiagnostically to ascertain the frequency of the tarsal tunnel syndrome and peripheral neuropathy. Four patients (13.3%) had evidence of the tarsal tunnel syndrome. The electrical abnormalities were mild and unassociated with specific clinical features. ...

Tarsal tunnel syndrome (TTS) is defined as the entrapment of the posterior tibial nerve in the tarsal tunnel of the ankle. The etiologies of tarsal tunnel syndrome are mainly the presence of a ganglion, osseous prominence with tarsal bone coalition, trauma, varicose veins, neurinoma, hypertrophy of the flexor retinaculum, or systemic disease (rheumatoid arthritis, ankylosing spondylitis). Howev...

Tarsal tunnel syndrome characterises a complex of symptoms that result from compression of the posterior tibial nerve as it passes through the fibro-osseus tunnel located beneath the flexor retinaculum on the medial aspect of the ankle.' The syndrome has been described in several case reports and review articles24 since Keck's5 and Lam's6 original case reports in 1962. Whereas other nerve entra...

In 14 patients tarsal tunnel syndrome was associated with varus heels and pronated, splayed forefeet. Review of the literature and the author's experience suggest that these conditions may be a common cause of the tarsal tunnel syndrome. Treatment of fixed varus deformities of the heel by outer heel wedges has been shown to be ineffective. Although outer heel wedges provide symptomatic relief i...

Tarsal tunnel intracompartment pressures were determined in 10 fresh-frozen normal human adult cadaver specimens. With the foot and ankle held in mild plantarflexion and neutral eversion-inversion, mean tarsal tunnel pressure was minimal (2 +/- 1 mmHg). However, when the foot and ankle were positioned in full eversion, mean tarsal tunnel pressure increased to 32 +/- 5 mmHg (P < or = 0.005); in ...

Background/objective Tarsal tunnel syndrome is a relatively rare entrapment neuropathy with the lateral and medial plantar nerves entrapped inside of the tarsal tunnel. When conservative treatment fails, standard open decompression of the nerve can be achieved by releasing the flexor retinaculum of the foot through a several-centimetre-long skin incision made along the tarsal tunnel. By contras...

Seven patients with clinical and electroneurographic evidence of tarsal tunnel syndrome were managed surgically, after failed attempts for non-surgical treatment. Post-operative results were more satisfactory than the previous responses to non-surgical therapies. Tarsal tunnel syndrome appears to respond better to surgical intervention than to conservative management.

Tarsal tunnel surgery complicated with ganglia or any other type of cystic mass can be a very challenging operation. Preoperative planning before any tarsal tunnel surgery involving a soft-tissue mass is imperative. Plans to reconstruct the posterior tibial nerve and/or artery should be in place. The authors will present a case study that involved tarsal tunnel syndrome with an associated gangl...

The near-nerve sensory nerve conduction in the medial and lateral plantar nerves was studied in 25 cases of tarsal tunnel syndrome. Sensory nerve conduction was abnormal in 24 cases (96%) The most common abnormalities were slow nerve conduction velocities and dispersion phenomenon (prolonged duration of compound nerve action potentials). These two electrophysiological abnormalities are indicati...
