After an injury to the right ring finger, a 44-year-old woman experienced pain in the distal interphalangeal joint. A subcutaneous mucoid cyst was noted near the joint. The x-ray films revealed no fracture but a narrowing of the joint space and a well-defined radiolucent area in the ulnar condyle of the middle phalanx. The biopsy specimen of this area excluded infection or tumor and revealed active osteogenic remodelling. These elements permitted a diagnosis of distal interphalangeal osteoarthritis that was associated with highly localized Sudeck's dystrophy (also called " parcellar algodystrophy"). This unusual case suggests the possibility that this dystrophy might be favored by an "osteoarthritic terrain" and might also play a role in the evolution of the osteoarthritis.
一名44岁女性右手环指受伤后，远侧指间关节出现疼痛。在关节附近发现一个皮下黏液样囊肿。X线片显示无骨折，但关节间隙变窄，中节指骨尺侧髁有一个边界清晰的透亮区。该区域的活检标本排除了感染或肿瘤，显示有活跃的成骨重塑。这些表现支持诊断为与高度局限性苏戴克营养不良（也称为“局限性痛性营养不良”）相关的远侧指间关节骨关节炎。这个不寻常的病例提示，这种营养不良可能因“骨关节炎环境”而更易发生，并且可能在骨关节炎的发展过程中起作用。
