Volar rotatory dislocation of the proximal interphalangeal (PIP) joint often cannot be reduced by closed manipulation because of interposition of soft tissues. In this case, the condyle of the proximal phalanx was trapped between the central slip and the lateral band. This case is reported to reemphasize the importance of recognizing serious injuries involving the soft tissues around the PIP joint. Deprival of its normal dorsal stabilizing forces can cause a loss of both static and dynamic joint support. Secondary scarring and contractures affect all damaged structures of the joint.
近端指间关节（PIP）掌侧旋转脱位通常因软组织嵌入而无法通过闭合手法复位。在本病例中，近节指骨髁被困于中央束与侧束之间。报道此病例是为了再次强调认识到涉及PIP关节周围软组织严重损伤的重要性。其正常背侧稳定力的丧失可导致静态和动态关节支持功能的丧失。继发性瘢痕形成和挛缩会影响关节的所有受损结构。
