摘要 目的:Delta陶瓷较Forte陶瓷在材料复合方面进步明显,并采用了36 mm大直径球头的设计,其组成的界面具有耐磨性好,关节活动度大,稳定性佳,不易脱位等优点,适合年轻及活动量大的患者,但其价格较其他界面更为高昂。观察采用Delta陶瓷-陶瓷界面与Delta陶瓷-高交联聚乙烯界面假体行全髋关节置换术的患者术后效果的差异。方法:选取2009年10月-2012年10月在我院选择Delta陶瓷-高交联聚乙烯界面行全髋关节置换术的35例患者(A组),以同期在我院选择Delta陶瓷-陶瓷界面26例行全髋关节置换术的患者(B组)作为对照。通过随访影像学复查,以及术后Harris功能评分进行临床效果的评价。结果:所有患者均得到随访,随访时间6个月到2年。所有患者在影像学方面,未发现松动下沉,脱位以及碎裂等现象。假体周围未见骨溶解所致透亮线形成以及异位骨化。两组患者行人工全髋关节置换术后Harris评分较术前均有显著提高,但两组之间无显著差异。结论:Delta陶瓷作为最新一代的生物陶瓷,其优异性能毋庸置疑。采用Delta陶瓷-陶瓷界面及Delta陶瓷-高交联聚乙烯界面在短期内未见明显差异,其中长期效果仍有待进一步随访观察。 Objective: To evaluate the difference between Delta BIOLOX COC bearing and COP bearing in early functional rehabilitation following THA.Methods: 35 patients who underwent BIOLOX Delta COP bearings(Cohort A),compare with 26 patients who underwent BIOLOX Delta COC bearings(Cohort B) in the same period.Evaluate the difference of two groups by radiograph and Harris score.Results: Wear,osteolysis and loosening were negative in radiographs of all the patients.The Harris score had no difference between the two groups(P0.05),but both of the scores made a progress after the surgery.Conclusion: BIOLOX Delta has outstanding performance.There is no difference between COC bearing group and COP bearing group in short-term curative effect,and the long-term effect should be explored.
