This study was performed to determine whether patients who sustain an intertrochanteric fracture have better outcomes when stabilized using a sliding hip screw or an intramedullary nail. A 20% sample of Part A and B entitled Medicare beneficiaries 65 years or older was used to generate a cohort of patients who sustained intertrochanteric femur fractures between 1999 and 2001. Two fracture implant groups, intramedullary nail and sliding hip screw, were identified using Current Procedural Terminology and International Classification of Diseases, 9th Revision codes. The cohort consisted of 43,659 patients. Patients treated with an intramedullary nail had higher rates of revision surgery during the first year than those treated with a sliding hip screw (7.2% intramedullary nail versus 5.5% sliding hip screw). Mortality rates at 30 days (14.2% intramedullary nail versus 15.8% sliding hip screw) and 1 year (30.7% intramedullary nail versus 32.5% sliding hip screw) were similar. Adjusted secondary outcome measures showed significant increases in the intramedullary nail group relative to the sliding hip screw group for index hospital length of stay, days of rehabilitation services in the first 6 months after discharge, and total expenditures for doctor and hospital services.

本研究旨在确定使用滑动髋螺钉或髓内钉固定转子间骨折患者时,哪种方法能带来更好的治疗效果。我们从名为“医疗保险受益人(65岁及以上)”的A部分和B部分中抽取了20%的样本,以生成一个1999年至2001年间发生股骨转子间骨折的患者队列。利用现行手术操作术语和《国际疾病分类》第九版编码确定了两个骨折植入物组,即髓内钉组和滑动髋螺钉组。该队列由43659名患者组成。与接受滑动髋螺钉治疗的患者相比,接受髓内钉治疗的患者在第一年进行翻修手术的比例更高(髓内钉组为7.2%,滑动髋螺钉组为5.5%)。30天(髓内钉组为14.2%,滑动髋螺钉组为15.8%)和1年(髓内钉组为30.7%,滑动髋螺钉组为32.5%)的死亡率相似。调整后的次要结局指标显示,相对于滑动髋螺钉组,髓内钉组在索引医院住院时间、出院后前6个月的康复服务天数以及医生和医院服务总费用方面均有显著增加。
