One hundred thirty-one patients with reoperation for carpal tunnel syn
drome were followed for a mean of 11 years. Reoperation failed in 15 p
atients, necessitating a third operation. Satisfaction, symptom severi
ty, and functional status scores were assessed with a standardized que
stionnaire in the other 116 patients. Patients with normal findings on
preoperative nerve conduction studies, those who filed for compensati
on, and those who had pain in the distribution of the ulnar nerve had
significantly worse results. Those with abnormal findings on nerve con
duction studies who had not filed for compensation had the best sympto
m and function scores and satisfaction al latest follow-up examination
; those with normal findings on nerve conduction studies who had filed
for compensation had the poorest outcome. Although most patients were
satisfied with the overall outcome, many reported residual symptoms;
in addition to the 15 patients wile required a third operation, 22 pat
ients were dissatisfied with the final result.
