Severe contractures of the proximal interphalangeal joint in Dupuytren's disease: combined fasciectomy with capsuloligamentous release versus fasciectomy alone.

Severe proximal interphalangeal joint contracture in Dupuytren's disease presents a frustrating problem for hand surgeon. Some surgeons argue for fasciectomy alone, avoiding violation of the proximal interphalangeal joint, which may prolong morbidity and result in permanent limitation of flexion; this loss of flexion can be more disabling than a mild flexion contracture. Others favor capsulotomy in addition to fasciectomy, especially for severe contractures, to obtain additional release, arguing that one cannot completely correct secondary contracture by fasciectomy alone. We performed a retrospective review of severe flexion contractures (60 degrees or greater) involving 42 proximal interphalangeal joints in 28 patients with Dupuytren's disease. Twenty-seven joints in 18 patients underwent fasciectomy alone, and 15 joints in 10 demographically similar patients underwent capsulotomy in addition to fasciectomy. In the noncapsulotomy group, preoperative contracture averaged 78.4 degrees. Postoperative contracture averaged 36.6 degrees, with a 53 percent improvement. In the capsulotomy group, preoperative joint contracture averaged 82.5 degrees. Postoperative contracture averaged 36.8 degrees, with a 55 percent improvement. Intraoperative residual contracture for 21 of the 27 joints in the noncapsulotomy group averaged 7 degrees compared with 8 degrees for 9 of the 15 joints in the capsulotomy group. Preoperative proximal interphalangeal joint flexion averaged 100.6 degrees in the noncapsulotomy group and 98.6 degrees in the capsulotomy group. Postoperative flexion averaged 92.2 degrees in the noncapsulotomy group, which was 91.7 percent of preoperative flexion, and 82.7 degrees, which was 83.9 percent of preoperative flexion, in the capsulotomy group. No statistically significant difference was seen in the percentage of contracture correction in the capsulotomy group compared with the noncapsulotomy group at follow-up. The degree of correction initially obtained at surgery using either method was not maintained during the short follow-up period. There was a significant decrease in postoperative proximal interphalangeal joint flexion compared with preoperative flexion following either surgical approach; however, there was no significant difference between the two groups with respect to the percentage of flexion lost. Complications developed in both groups but tended to occur more commonly in the capsulotomy group. This study failed to show any advantage to capsuloligamentous release in addition to fasciectomy in treating severe proximal interphalangeal joint contracture due to Dupuytren's disease.
