当科における足根管症候群の手術例の検討

Abstract

We examined the clinical results of surgical treatment for tarsal tunnel syndrome. During the period from April 1986 to August 2002, we treated 81 feet in 62 patients including 11 feet in 6 recurrent cases. Twenty-five feet were left, 26 were right and 15 were bilateral. There were 26 males and 36 females. The average age was 50.2 years (range: 13 to 79 years). Evaluation was performed at a mean follow-up of 27.8 months (range: 1 to 177 months) after the operation. Causes of the tarsal tunnel syndrome were fascia cruris in 6 feet, flexor retinaculum in 30 feet, level of abductor hallucis muscle in 81 feet, tendonitis or tenosynovitis in 7 feet, ganglion or tumors in 7 feet, deformity of bone or joints, varix in 5 feet, and muscle anomaly in 1 foot. Recurrent cases were caused by scar or adhesion of the tibial nerve except for a recurrence case of ganglion. Results were excellent in 78 feet and poor in 3 feet. We believe that careful hemostasis is important for the surgical treatment of tarsal tunnel syndrome to prevent or minimize scar formation or adhesion around the operative nerve.
