ABSTRACT
One year follow-up results after hypothenar fat pad flap surgery for recurrent and end stage carpal tunnel syndrome (CTS) are reported. Before surgery, the patients' complaints with a recurrent CTS were mainly pain and return of pathological symptoms (tingling, nocturnal pain, etc.) whereas the patients with end stage CTS reported problems of loss of sensation. Both groups (8 patients in each group) reported a limited functional status for activity of daily living (ADL) prior to surgery. Evaluations of sensibility, strength, pain and Boston Carpal Tunnel Questionnaire were made preoperatively and postoperatively at 3, 6 and 12 months. The major clinical issues for both groups were statistically significantly improved after one year, but already significant results were noted after 3 months. We confirm that the hypothenar fat pad flap is a good solution for recurrent CTS. Moreover, end stage CTS could be a new and promising indication for the use of this vascularized flap.
