Rupture of the extensor pollicis longus tendon at the tip of a prominent fixation screw occurred in two cases after fixation of fractures of the radial shaft and in one case after fixation of a fracture of the scaphoid. Patients were referred because of their inability to extend the thumb. Active thumb extension was restored in two patients by screw removal and tendon transfer. The third patient elected nonoperative care. Close scrutiny of good-quality intraoperative x-ray films after internal fixation about the wrist may detect screws that are too prominent and thereby prevent rupture of the extensor pollicis longus tendon.
在两例桡骨干骨折固定术后及一例舟骨骨折固定术后，突出的固定螺钉尖端处发生了拇长伸肌腱断裂。患者因无法伸直拇指前来就诊。两名患者通过取出螺钉和肌腱转移恢复了拇指的主动伸直功能。第三名患者选择了非手术治疗。对腕部内固定术后高质量术中X线片进行仔细检查，可能会发现过于突出的螺钉，从而预防拇长伸肌腱断裂。
