Ten cases of closed extensor tendon rupture at the musculotendinous junction are reported. In five patients the rupture occurred at work, and in five during athletic activities. In each instance, indirect tendon injury resulted from a strong stretching force applied to a contracting muscle. In one case, rupture of the extensor pollicis longus tendon occurred proximal to the extensor retinaculum. In eight cases of complete tendon rupture direct repair was impossible. Of these eight patients, five were treated by side-to-side juncture and three by tendon transfer. Two patients with incomplete rupture were treated by splinting. All patients improved after treatment.
报告了10例闭合性伸肌腱在肌-腱连接处的断裂情况。5例患者在工作时发生断裂，5例在体育活动期间发生断裂。在每个病例中，间接肌腱损伤是由于对收缩的肌肉施加强大的拉伸力所致。1例患者的拇长伸肌腱在伸肌支持带近端发生断裂。8例肌腱完全断裂的患者无法进行直接修复。在这8例患者中，5例采用侧-侧吻合术治疗，3例采用肌腱转移术治疗。2例不完全断裂的患者采用夹板固定治疗。所有患者治疗后均有改善。
