Injury to the central slip of the extensor tendon may occur with open and also with closed injuries, such as volar dislocation of the proximal interphalangeal (PIP) joint. For adequate treatment, it is necessary to identify all injured structures. Without appropriate primary management, the patient is likely to develop a subacute to chronic posttraumatic boutonnière deformity. A fixed boutonnière deformity requires recovery of joint mobility. Once joint mobility is achieved, secondary surgical reconstruction of the central slip can be performed with a tendon transfer or a tendon transplant.
伸肌腱中央束损伤可发生于开放性损伤，也可发生于闭合性损伤，如近端指间关节掌侧脱位。为了进行充分治疗，有必要识别所有受损结构。如果没有适当的初期处理，患者很可能发展为亚急性至慢性创伤后纽扣指畸形。固定性纽扣指畸形需要恢复关节活动度。一旦实现关节活动度，可通过肌腱转移或肌腱移植对中央束进行二期手术重建。
