Minimally invasive partial fasciectomy for Dupuytren's contractures.

BACKGROUND: Numerous options exist for the treatment of Dupuytren's contracture. This study describes the technique and early results of partial fasciectomy through a mini-incision approach as an additional treatment option for Dupuytren's disease.

METHODS: This procedure involves the excision of diseased Dupuytren's tissue with the use of multiple 1 cm transverse incisions. Patient demographics, digit involvement, the number of incisions required to release each digit, and complications were recorded for all patients. Range of motion data was obtained from a subgroup of patients that had at least 6 months of follow-up. A paired t test was used to compare preoperative and postoperative contracture.

RESULTS: Sixty-seven patients underwent 75 procedures that involved 119 digits. The mean patient age at the time of surgery was 63 years (range, 33-95 years). A total of 32 digits (47 joints) were available for range of motion analysis. After a mean of 2.2 years following surgery, metacarpophalangeal joint contractures maintained correction (34° preoperatively, 19° postoperatively, p = 0.008). After a mean postoperative duration of 2.0 years, proximal interphalangeal joint contractures trended worse than preoperative levels (39° preoperatively, 45° postoperatively, p = 0.319). There was one major complication, which consisted of a nerve laceration that was identified and repaired intraoperatively.

CONCLUSIONS: Partial fasciectomy through the described mini-incision approach provides an additional surgical option for patients who desire a less invasive surgical procedure than traditional fascietomy. Although this procedure is safe and effective at achieving immediate cord release, maintenance of correction for proximal interphalangeal joint contractures remains problematic.
