Thirty-nine consecutive patients with little finger Dupuytren's contracture underwent open fasciectomy. Diseased abductor digiti minimi (ADM) pretendinous (PT) cords were identified. The mean pre-operative PIPJ contracture was 77 degrees in the PT group and 66 degrees in the ADM group. Mean residual deformity was 12 degrees in the PT group and 9 degrees in the ADM group. At six months, ten out of 27 patients had developed a recurrent deformity in the PT group (mean 24 degrees ) and seven out of 11 in the ADM group (mean 18 degrees ). There was no statistically significant difference between the two groups at any stage. Dupuytren's contracture of the little finger is as a result of an ADM cord in 29% of cases. In this series it led to an isolated contracture of the PIPJ in the majority of cases and rarely affected the MCPJ. Disease of the ADM cord was not associated with a difference in contracture or prognosis compared to a PT cord.
39例患有小指掌腱膜挛缩症的患者连续接受了开放性筋膜切除术。确定了患病的小指展肌（ADM）假腱性（PT）条索。PT组术前近端指间关节（PIPJ）挛缩平均为77度，ADM组为66度。PT组平均残留畸形为12度，ADM组为9度。在六个月时，PT组27例患者中有10例出现复发畸形（平均24度），ADM组11例中有7例（平均18度）。两组在任何阶段均无统计学显著差异。29%的小指掌腱膜挛缩症病例是由ADM条索引起的。在本系列中，大多数病例导致PIPJ孤立性挛缩，很少影响掌指关节（MCPJ）。与PT条索相比，ADM条索疾病与挛缩或预后差异无关。
