Type III open fractures of the humerus caused by high energy missiles or shrapnel in 26 male soldiers were treated by external fixation. 12 suffered from associated injuries involving the head and chest, 12 had 14 nerve injuries, and 4 required simultaneous repair of the brachial artery. Results in 19 examined after an average of 6.5 years were excellent in 22%, good in 52%, fair in 16%, and poor in 10%. The aim of external fixation is functional limb salvage. We think high-energy gunshot fractures should be classified as III-d because of the severe damage to the soft tissue, which differs from that of low-velocity, gunshot fractures or farm injuries. We conclude that external fixation is the preferred form of primary stabilization of severe open fractures of the humerus. It has reduced the incidence of chronic infection and has improved the prognosis of vascular repairs. The treatment of the soft tissues, skin coverage, and ultimately reconstructive surgery are facilitated. Early limb function allows for a better final result. For delayed union and pin-tract infection a different definitive method, such as internal fixation or a plaster case, is required.
对26名因高能导弹或弹片导致肱骨Ⅲ型开放性骨折的男性士兵采用外固定治疗。12例伴有头部和胸部的相关损伤,12例有14处神经损伤,4例需要同时修复肱动脉。平均6.5年后对19例进行检查,结果优占22%,良占52%,可占16%,差占10%。外固定的目的是挽救有功能的肢体。我们认为,由于软组织严重损伤,高能枪伤骨折应归类为Ⅲ - d型,这与低速枪伤骨折或农业损伤不同。我们得出结论,外固定是肱骨严重开放性骨折一期稳定的首选方式。它降低了慢性感染的发生率,改善了血管修复的预后。有利于软组织处理、皮肤覆盖以及最终的重建手术。早期的肢体功能可带来更好的最终结果。对于延迟愈合和针道感染,需要采用不同的确定性方法,如内固定或石膏固定。
