A study of 75 patients with displaced cervical hip fractures was done utilizing two different multiple pinning techniques with threaded screws. One was the refined method of internal fixation by which the strongest bone of the femoral head was utilized to increase the stability of the fracture, and the other was the von Bahr method. As much as possible, other factors influencing healing were standardized in both groups. Forty-three of the patients were treated with the refined method and 32 with the von Bahr method. Complications occurred in 5 of 43 patients in the group treated with the new method, compared with 12 of 32 patients in the von Bahr group. Early redisplacement and nonunion were more common in the von Bahr group. Late segmental collapse was the same in both groups. In our opinion the early complications of redisplacement and nonunion are due to poor stability of the fracture. With the new, refined method, it is possible to reduce these complications.
对75例移位型股骨颈骨折患者进行了一项研究，采用了两种不同的带螺纹螺钉的多针固定技术。一种是改良的内固定方法，即利用股骨头最强壮的骨质来增加骨折的稳定性，另一种是冯·巴尔方法。两组中尽可能使影响愈合的其他因素标准化。43例患者采用改良方法治疗，32例采用冯·巴尔方法治疗。改良方法治疗组的43例患者中有5例发生并发症，而冯·巴尔组的32例患者中有12例发生并发症。早期再移位和骨不连在冯·巴尔组更为常见。两组晚期节段性塌陷情况相同。我们认为，早期再移位和骨不连并发症是由于骨折稳定性差所致。采用新的改良方法，可以减少这些并发症。
