Fracture dislocations of the proximal interphalangeal (PIP) joint of the finger are often caused by axial load applied to a flexed joint. The most common injury pattern is a dorsal fracture dislocation with a volar lip fracture of the middle phalanx. Damage to the soft-tissue stabilizers of the PIP joint contributes to the deformity seen with these fracture patterns. Unfortunately, these injuries are commonly written off and left untreated. A late-presenting PIP joint fracture dislocation has a poor chance of regaining normal range of motion. The provider must be suspicious of these injuries. Treatment options and algorithm are reviewed.
手指近端指间关节（PIP）的骨折脱位通常由施加于屈曲关节的轴向负荷引起。最常见的损伤类型是伴有中节指骨掌侧唇骨折的背侧骨折脱位。PIP关节软组织稳定器的损伤导致了这些骨折类型所出现的畸形。不幸的是，这些损伤常常被忽视且未得到治疗。晚期出现的PIP关节骨折脱位恢复正常活动范围的机会很小。医疗人员必须对这些损伤保持警惕。本文对治疗选择和治疗方案进行了综述。
