黑晶头和陶瓷头假体在人工髋关节置换中的疗效比较

Comparison of clinical efficacies between black crystal head and ceramic head prosthesis in artificial hip joint replacement

目的探讨黑晶头和陶瓷头假体在人工髋关节置换术的近期临床疗效、生物性能及应用价值。方法回顾性分析56例髋关节置换术患者的临床资料,A组36髋为黑晶头人工髋关节置换(n=28);B组32髋为陶瓷头人工髋关节置换(n=28)。结果A组平均手术时间(56.13±1.25)min,术中平均出血量(245.00±18.26)mL;B组手术时间(57.02±1.01)min;术中出血量(243.00±20.67)mL(P>0.05)。术后随访48例,患者伤口愈合良好,愈合时间4~6个月。A组Harris术前评分(23.12±4.23)分,术后评分(86.33±3.56)分;B组Harris术前评分(23.47±3.98)分,术后评分(88.22±3.42)分(P>0.05)。X线片显示两组患者术后48个月人工关节均未引起任何并发症,假体与患者髋骨间连接紧密,假体无松动、磨损现象。结论黑晶头和陶瓷头假体髋关节置换术的临床疗效相当,但黑晶头相比陶瓷头具有价格优势。

Objective To explore the short-term clinical curative effect,biological properties and application value of black crystal head and ceramic head prosthesis in artificial hip replacement.Methods The clinical data in 56 cases of hip arthroplasty were retrospectively analyzed.The group A(36 hips,n=28)used the black crystal head artificial hip replacement;the group B(32 hips,n=28).Results The mean time of operation was(56.13±1.25)min and the average intraoperative blood volume was(245.00±18.26)mL in the group A;while which was(57.02±1.01)min and(243.00±20.67)mL in the group B(P>0.05).Forty-eight cases were followed up with good healing,the healing time ranged 4-6 months.The Harris scores were(23.12±4.23)points before operation and(86.33±3.56)after surgery in the group A;while which were(23.47±3.98)points and(88.22±3.42)points after surgery in the group B(P>0.05).The X-ray film showed that postoperative 48 months did not cause any complications,the prosthesis was closely connected with the hip bone of patients,and no loose or abrasion occurred.Conclusion The clinical efficacy of black crystal head and ceramic head prosthesis hip arthroplasty is similar,but black crystal head has price advantage over ceramic head.
