Abstract

The thirty-five patients of carpal tunnel syndrome which were confirmed by clinical and electrodiag- nostic methods from July, 1990 to October, 1995 were treated by surgical release of transverse carpal ligament. Among the thirty-five patients, the severe carpal tunnel syndrome was the thirty-three hands in twenty-two patients which were followed up from twelve months to fifty-seven months and evaluated the changes of nerve conduction studies, two point discrimination, muscle strength and muscle atrophy, preoperatively and postoperatively. Five(55.6% ) of the nine hands that was greater than 15mm preoperatively improved to the normal. The other four cases improved to an average 8.5mm. Of the 18 cases with preoperative two-point discrimination less than 15mm, the average preoperative measurement was 10.26mm, changing to 5.45mm, postoperatively. Fourteen(51.8%) of twenty-seven hands that had had hypotrophy of thenar muscle regained normal muscle bulk. The twelve hands had had severe hypotrophy and fifteen hands had had mild to moderate hypotrophy preoperatively. Eighteen(94.7%) of nineteen hands that had weakness of the thenar muscles(grade 3 strength or less) regained grade 4 or 5 strength. Seventeen(77% ) of the twenty-two patients had complete resolution of symptoms and signs of carpal tunnel syndrome.
