Forty-three fractures of the shaft of the femur secondary to low-velocity gunshot wounds were evaluated to determine healing time, fracture alignment after healing, complications, and fracture characteristics. This study confirmed the previous reports of low infection rates and the need for minimal debridement for such fractures. The healing time was faster than that of closed fractures treated by similar means: the average healing time was 144.3 days. Alignment was easy to obtain and maintain, the average angular deformity being 5 degree or less with no rotational deformities. Three characteristic fracture types were noted: the double butterfly configuration of the shaft of the femur, the drill-hole fracture of the distal third of the femur as previously described experimentally, and a third type of fracture with an incomplete fracture secondary to the gunshot wound which acted as a stress riser with a resultant spiral fracture either proximal or distal to the impact site.
对43例因低速枪伤导致的股骨干骨折进行评估，以确定愈合时间、愈合后的骨折对线情况、并发症及骨折特征。本研究证实了先前关于此类骨折感染率低以及清创需 minimal 的报道。其愈合时间比采用类似方法治疗的闭合性骨折更快：平均愈合时间为144.3天。对线易于获得并维持，平均角畸形为5度或更小，无旋转畸形。记录到三种特征性骨折类型：股骨干双蝶形骨折、如先前实验所描述的股骨远端三分之一的钻孔骨折，以及第三种骨折类型，即枪伤导致的不完全骨折，其作为应力集中点，在撞击部位近端或远端引发螺旋骨折。
