Tenolysis after combined digital injuries in zone II.

A retrospective review of 23 patients with restricted motion after 32 combined digital injuries or amputations in zone II treated with tenolysis was conducted at an average follow-up of 5 years. Significant functional improvement was achieved in 28 out of 32 digits (88%). Total active motion improved on average 51 degrees after dorsal tenolysis, 55 degrees after palmar tenolysis, and 63 degrees after combined dorsopalmar tenolysis. Using the Buck-Gramcko scoring system, 15 digits reached excellent results, 8 showed a good result, 4 had a fair result, and 5 were rated as poor. No digits were lost. All patients returned to a full-time job. Complications consisted of 16% flexor tendon ruptures after palmar or combined tenolyses. In contrast, dorsal tenolysis proved to be a safe procedure. Prerequisites for success are compliant patients who are willing to undergo therapy for at least 3 months postoperatively. Despite the demanding postoperative therapy, the individual patient satisfaction is high following tenolysis.
