In the patient with scarring of just the central band and lateral bands, there is a loss of active and passive flexion of the proximal interphalangeal (PIP) joint because the lateral bands have lost their normal volar shift. Surgical freeing of the lateral bands from the central band using parallel incisions may be required to allow full flexion of the PIP joint. This study reports on 10 patients with post-traumatic extension contracture of the PIP joint treated by lateral band release. All operations were successful, with an average gain in range of motion of 47.5 degrees. This technique is simple, quick, and can be performed effectively on an out-patient basis.
在仅中央束和外侧束瘢痕形成的患者中，近端指间关节（PIP）的主动和被动屈曲丧失，因为外侧束失去了正常的掌侧移位。可能需要使用平行切口将外侧束从中央束上手术松解，以使PIP关节完全屈曲。本研究报告了10例经外侧束松解治疗的创伤后PIP关节伸直挛缩患者。所有手术均成功，平均活动范围增加47.5度。该技术简单、快速，可在门诊有效实施。
