Complications of a simple procedure: de Quervain's disease revisited.

We reviewed the results of 22 operations performed on 21 patients for the relief of de Quervain's disease over the last six years. At a mean follow-up of 34 months (range 4-78 months), 18 of 22 wrists had complete relief of their original symptoms. One patient required reoperation because of inadequate decompression, and two others await further surgery. Most operations (14 out of 22) were performed under local anaesthesia, and 17 out of 22 used a longitudinal incision. The use of a longitudinal incision was associated with a significant risk of complications: four patients had a poor cosmetic result, and six showed evidence of superficial radial nerve injury. Two patients had a wound infection, and one developed reflex sympathetic dystrophy. Although surgical decompression for de Quervain's disease is effective in curing the symptoms in most patients, using a longitudinal incision is associated with poor wound healing and damage to the terminal branches of the radial nerve.
