Management of recurrence of carpal tunnel syndrome by using the abductor digiti minimi muscle flap to cover the median nerve

Recurrent carpal tunnel syndrome is a clinical problem that continues to be a challenge in the hand surgery practice.It is a different entity with less favorable successes in diagnosis and treatment compared to primary carpal tunnel syndrome.Results after surgery depend on the strategy chosen to address the problem. A second, more ulnar incision has been propagated [1, 2].Intraoperative findings consist of extensive fibrosis with nerve adhesions with flexor tendons or the roof of the tunnel. This implies that pathophysiology may be the lack of nerve gliding as well as compression of the nerve.Besides neurolysis it might be worthwhile bringing vascularized tissue to the bed of the median nerve [3].
