Comparison of surgical treatments for mucous cysts of the distal interphalangeal joint.

Mucous cysts of the interphalangeal joints are common. Several surgical techniques have been described, but none has proven to be superior. We compared three techniques that entail complete removal of the cyst together with the concomitant osteophytes. In group A wound closure was obtained by full thickness skin graft, in group B by primary closure and in group C by a local skin graft. Sixty-four patients with 70 cysts were reviewed. An overall recurrence rate of 8.6% was observed. Forty-five of the studied patients received a full thickness skin graft (4 out of 45 recurred), 23 were closed primarily (2 out of 23 recurred) and 2 by a local skin graft (no recurrences). Full thickness skin graft showed no significant higher recurrence compared to primary closure. Full thickness skin graft showed no significant higher pain or satisfaction compared to primary closure. Patients with a recurrent cyst were less satisfied and had more pain than those without recurrences.
