Traumatic dislocation of the interphalangeal of the fifth toe is an unusual foot injury.
We report the case of a 47-year-old woman who sustained a minor foot injury for more than 30 years, resulting in chronic, irreducible dislocation of the proximal interphalangeal joint of the fifth toe. The affected proximal interphalangeal joint was accessed via a dorsal incision over the unstable interphalangeal joint. It was found that the interposed interphalangeal joint capsule and attenuated lateral collateral ligament were reconstructed, and it was stabilized by temporary insertion of a Kirschner wire. The affected joint was found to be stable, well-positioned and pain-free at the 12-month post-surgical check-up.
This unusual presentation of a chronic joint dislocation responded favorably to open reduction, soft tissue reconstruction and restabilization of the affected joint. It is suggested that this approach will provide a good and functional outcome even in cases of very long-standing joint injury.
第五趾趾间关节创伤性脱位是一种不常见的足部损伤。
我们报告一例47岁女性，其足部受轻伤30多年，导致第五趾近侧趾间关节慢性、不可复位性脱位。通过不稳定趾间关节上方的背侧切口显露受影响的近侧趾间关节。发现重建了嵌入的趾间关节囊和变细的外侧副韧带，并通过临时插入克氏针使其稳定。术后12个月复查时，发现受影响的关节稳定、位置良好且无疼痛。
这种慢性关节脱位的不寻常表现对切开复位、软组织重建及受影响关节的重新稳定治疗反应良好。建议即使在关节损伤时间很长的情况下，这种方法也能提供良好的功能结果。
