A prospective, randomized clinical study has been performed on 104 patients with an acute femoral neck fracture, comparing internal fixation (von Bahr screws) with primary prosthetic replacement (Christiansen endoprosthesis). Immediate weight bearing was allowed in both groups. The postoperative mortality rate was similar in the two groups. Internal fixation proved to be a less time-consuming operation, gave a shorter hospitalization time and was associated with a significantly reduced morbidity rate compared with prosthetic replacement. No blood transfusion was needed in the internal fixation group. Primary prosthetic replacement was associated with earlier postoperative mobilization, probably gave a more definitive treatment with fewer reoperations, and showed better results at 1-year follow-up.
对104例急性股骨颈骨折患者进行了一项前瞻性随机临床研究，比较了内固定（冯·巴尔螺钉）与一期假体置换（克里斯蒂安森内置假体）。两组均允许立即负重。两组术后死亡率相似。与假体置换相比，内固定被证明是一种耗时较少的手术，住院时间更短，发病率显著降低。内固定组无需输血。一期假体置换与术后更早活动相关，可能提供更确切的治疗，再次手术更少，并且在1年随访时效果更好。
