One hundred and six patients with 108 femoral shaft fractures were treated with a cast-brace. Ninety-eight cast-braces included an abdominal band and hip hinge. At follow-up three femora showed coronal malalignment that exceeded 9 degrees and sixty-nine showed varying degrees of sagittal malalignment (thirty-eight having anterior bowing and thirty-one, posterior bowing). Four patients regained only 100 degrees of knee flexion or less and four others had hyperextension of the knee of more than 10 degrees. Thirty-eight patients showed signs of knee instability but only four of them had symptoms of instability. Four fractures were treated operatively to correct excessive shortening or angulation and another fracture was bone-grafted to promote union. The mean shortening was 10.9 millimeters (standard deviation, 8.8 millimeters). Although the more comminuted of the eighty-five middle-third fractures shortened more than the others, the results of this method of treatment for these comminuted fractures were acceptable.
106例患有108处股骨干骨折的患者接受了石膏支具治疗。98个石膏支具包括腹带和髋关节铰链。随访时，3个股骨出现超过9度的冠状面畸形，69个股骨出现不同程度的矢状面畸形（38例向前成角，31例向后成角）。4例患者膝关节仅恢复到100度或更小的屈曲度，另外4例患者膝关节过伸超过10度。38例患者有膝关节不稳定的体征，但只有4例有不稳定症状。4处骨折接受了手术治疗以纠正过度缩短或成角，另一处骨折进行了植骨以促进愈合。平均缩短为10.9毫米（标准差，8.8毫米）。虽然85处中1/3骨折中粉碎程度较高的骨折比其他骨折缩短更多，但这种治疗方法对这些粉碎性骨折的效果是可以接受的。
