摘　　要：目的比较保留股骨颈型(CFP)假体与Ribbed假体在全髋关节置换术(THA)患者中应用效果。方法77例THA患者分别采用CFP(CFP组,41例)和Ribbed假体(Ribbed组,36例)治疗。记录手术相关指标,采用Harris髋关节功能评分(HHS评分)和WOMAC评分评估髋关节功能,根据影像学上Gruen分区及DeLee分区法来评估假体周围骨溶解、皮质骨增生及异位骨化和判定股骨假体柄是否处于中心位置;采用Engh标准评估骨-假体接触面的稳定性。结果两组手术时间和术中出血量相仿(P>0.05)。两组术后随访均超过3年,术后末次随访时HHS评分和WOMAC评分较术前改善(P<0.05)。两组并发症发生情况相仿(P>0.05);CFP组双下肢长度差>10 mm者8例(19.5%),Ribbed组则仅有1例(2.8%)(P<0.05)。结论THA中采用CFP假体或Ribbed假体均可取得良好临床疗效,但相比之下采用CFP更容易出现双下肢长度不等。Objective To compare the clinical efficacy of collum femoris preserving(CFP)prosthesis and Ribbed prosthesis applied in total hip arthroplasty(THA).Methods Seventy-seven THA patients(79 hips)were treated with CFP(group A,41 cases)prosthesis or Ribbed prosthesis(group B,36 cases).The operation-related indicators were recorded.Harris hip score(HHS)and Western Ontario and McMaster University Osteoarthritis Index(WOMAC)were used to evaluate hip joint function.The osteolysis,cortical bone hyperplasia and ectopic ossification around the prosthesis according were assessed acording to the Gruen zone and Delee zone on imaging.That whether the femoral prosthesis is in a neutral position was judged.The stability of bone-prosthetic contact was evaluated using Engh criteria.Results The operation time and blood loss in two groups were similar(P>0.05).The patients of two groups were followed up for more than 3 years.The last follow up showed that the HHS and WOMAC scores of two groups were significantly improved postoperatively(P<0.05).Complications of both groups were similar(P>0.05).There were 8 cases(19.5%)with leg-length difference>10 mm in group A,which was seen only 1 case(2.8%)in group B(P<0.05).Conclusion The use of CFP prosthesis or Ribbed prosthesis in THA can achieve good clinical efficacy.Compared to Ribbed prosthesis,the use of CFP prosthesis in THA is more prone to cause leg-length differences.
