In a series of 70 consecutive patients with nonpathologic intertrochanteric or subtrochanteric hip fractures, the first 35 were treated by a single semi-flexible condylocephalic nail. The second 35 patients were treated by a sliding compression screw and side-plate. The groups were comparable regarding age and intercurrent medical illness. The average anesthesia time and blood loss were nearly the same in each group. The incidence of failure of fracture fixation was high in the group treated by the condylocephalic nail, statistically significant at p less than .001. None of the patients treated by the sliding compression screw and side-plate lost fracture fixation. In this series, condylocephalic nails did not provide good fixation of this type of fracture and did not lessen surgical morbidity.
在连续70例非病理性转子间或转子下髋部骨折患者中，前35例采用单根半柔性髁头钉治疗。后35例患者采用滑动加压螺钉和侧板治疗。两组在年龄和并存疾病方面具有可比性。每组的平均麻醉时间和失血量几乎相同。采用髁头钉治疗的组骨折固定失败发生率较高，p值小于0.001，具有统计学意义。采用滑动加压螺钉和侧板治疗的患者均未出现骨折固定失败。在本系列研究中，髁头钉不能很好地固定此类骨折，也不能降低手术并发症的发生率。
