A stepwise logistic regression analysis was made to assess the influence of various factors on the rate of healing complications after femoral neck fracture. A prospective series comprising 101 patients with fresh fractures treated by closed reduction and internal fixation was included in a roentgenographic follow-up study. The single most important factor was the quality of reduction, followed by the type of fracture, and the position of the internal fixation material. Age, gender, and type of internal fixation device (three screws or three nails) were not found to influence the healing complication rate. The predicted probability of a healing complication for different combinations of the three most important factors ranged from 0.05 to 0.99. The highest value was found for the combination Garden Type IV fracture, which had unacceptable reduction and position of the internal fixation material. The results show that failure to achieve adequate reduction should be a strong argument in favor of primary hip arthroplasty.
进行了逐步逻辑回归分析,以评估各种因素对股骨颈骨折后愈合并发症发生率的影响。一项前瞻性研究纳入了101例接受闭合复位和内固定治疗的新鲜骨折患者,并对其进行了X线随访研究。最重要的单一因素是复位质量,其次是骨折类型和内固定材料的位置。未发现年龄、性别和内固定装置类型(三枚螺钉或三枚钉子)对愈合并发症发生率有影响。三个最重要因素不同组合的愈合并发症预测概率范围为0.05至0.99。Garden IV型骨折且复位及内固定材料位置不佳的组合预测概率最高。结果表明,未能实现充分复位应成为支持一期髋关节置换术的有力论据。
