Chronic subluxation of the extensor tendons of the metacarpal phalangeal joint has been documented in six patients on active duty in the United States Navy. These patients had painful full flexion and gripping in the knuckle, especially when they were performing their jobs. No extension lag was noted. Three patients had a severed junctura tendinum between the long and index fingers, which was believed to be a contributing factor to extensor tendon subluxation. Local anesthesia was administered to these patients, and the lesions were surgically corrected by reefing of the extensor hood and the sagittal band and repair of the junctura tendinum.
美国海军现役的6名患者被记录存在掌指关节伸肌腱慢性半脱位。这些患者在指关节处进行完全屈曲和抓握时会感到疼痛，尤其是在执行任务时。未发现伸展滞后。3名患者的示指与中指之间的腱间结合部断裂，这被认为是伸肌腱半脱位的一个促成因素。对这些患者实施了局部麻醉，并通过收紧伸肌帽和矢状带以及修复腱间结合部对病变进行了手术矫正。
