Simultaneous dislocation of the distal and proximal interphalangeal joints is an uncommon injury. Treating chronic cases proves challenging due to severe contractures affecting both joints and surrounding soft tissues. Here, we report an unusual chronic contracture case in a 46-year-old man who suffered a dorsal dislocation of the distal and proximal interphalangeal joints of the little finger. The patient underwent primary joint distraction followed by open reduction, leading to stable radiographic restoration and a functional range of motion in the affected finger 6 months postoperatively. Joint distraction was a reliable approach for the treatment of chronic joint dislocation with severe soft tissue contracture, especially for multiple joint contractures. In addition, the Ilizarov mini-fixator device was effective in enabling individualized traction on both the distal and proximal interphalangeal joints.
远侧指间关节和近侧指间关节同时脱位是一种罕见的损伤。由于影响两个关节及周围软组织的严重挛缩,治疗慢性病例具有挑战性。在此,我们报告一例不寻常的慢性挛缩病例,患者为一名46岁男性,其小指的远侧指间关节和近侧指间关节发生背侧脱位。患者接受了初次关节牵张,随后进行切开复位,术后6个月患指在影像学上恢复稳定且活动范围功能良好。关节牵张是治疗伴有严重软组织挛缩的慢性关节脱位的可靠方法,尤其是对于多个关节挛缩的情况。此外,伊利扎罗夫微型固定器装置有效地实现了对远侧指间关节和近侧指间关节的个体化牵引。
