Open fractures of both left ulna and radius, in which a segment of the radius was found to be missing, occurred in a 27-year-old man. The fractures were treated by open reduction, internal fixation with ASIF semitubular plates, and bone graft. Because of slow radiological union, regrafting was required twice. Approximately six months after the third operation, roentgenograms showed that the bone plate was broken, even though the fractures had been protected in a long-arm cast. The fatigue fracture of the plate, positioned on the posterior surface of the ulna, was presumably caused by the force of the finger flexors, most of which originate above the fracture site, and which were still able to contract because the fingers were not immobilized.
一名27岁男性出现左尺桡骨开放性骨折,其中桡骨有一段缺失。骨折采用切开复位、ASIF半管状钢板内固定及植骨治疗。由于放射学愈合缓慢,需要进行两次再次植骨。第三次手术后约六个月,X线片显示骨板断裂,尽管骨折部位用长臂石膏固定。位于尺骨后表面的钢板疲劳骨折,可能是由手指屈肌的力量引起的,这些屈肌大多起于骨折部位上方,且由于手指未固定仍能收缩。
