We performed a radiographic review of a consecutive series of 87 resurfacing arthroplasties of the hip, performed between 2004 and 2006. There were 54 cemented femoral components and 33 uncemented femoral components. All of the procedures were performed by the same surgeon using the same approach. There was no difference between the groups with regards to gender, age, pre-operative diagnosis and the average diameter of the components. The primary outcome measured was the neck-prosthesis ratio on standard anterior-posterior pelvis radiographs taken post-operatively and at a minimum follow up of two years. The difference between the immediate post-operative ratio and the most recent radiograph was statistically significant in patients with cemented femoral components (p=0.006), but not in the group with uncemented components (p=0.173). We have demonstrated a difference in narrowing of the femoral neck between cemented and uncemented femoral components in the first two years following surgery.
我们对2004年至2006年间连续进行的87例髋关节表面置换术进行了影像学回顾。其中有54个骨水泥固定的股骨组件和33个非骨水泥固定的股骨组件。所有手术均由同一位外科医生采用相同的方法进行。两组在性别、年龄、术前诊断和组件平均直径方面没有差异。主要测量指标是术后及至少两年随访时标准前后位骨盆X线片上的颈部假体比值。骨水泥固定股骨组件的患者术后即刻比值与最近一次X线片之间的差异具有统计学意义（p = 0.006），而非骨水泥固定组件组则无统计学意义（p = 0.173）。我们已经证明，在术后的头两年，骨水泥固定和非骨水泥固定的股骨组件在股骨颈变窄方面存在差异。
