摘要(Abstract):
[目的]探讨应用生物型翻修加长柄行人工髋关节翻修术的早期临床疗效。[方法]回顾性分析2013年1月~2015年7月于本科接受人工髋关节翻修术的73例(73髋)患者的病例资料,男46例,女27例;年龄46~78岁,平均(64.40±8.27)岁。髋关节翻修术距离初次人工全髋置换的时间是5~34年,平均8.6年。通过比较各组手术时间、术中出血量、住院时间、下地活动时间、随访时间、并发症和Harris髋关节评分评估临床疗效,术后定期复查X线片评估假体稳定性、骨长入等情况。[结果]全部病例随访时间8~36个月,平均(20.21±4.21)个月。手术时间假体无菌性松动组为(163.25±12.74)min,假体周围骨折组为(187.30±18.85)min,假体周围感染组为(127.35±10.27)min(F=43.89,P<0.01);术中出血量假体无菌性松动组为(382.52±47.53)ml,假体周围骨折组为(427.67±61.72)ml,假体周围感染组为(317.83±28.49)ml(F=12.24,P<0.01);平均住院时间假体无菌性松动组为(10.40±3.35)d,假体周围骨折组为(16.31±4.43)d,假体周围感染组为(10.84±2.36)d(F=19.46,P<0.01);平均下地活动时间假体无菌性松动组为(24.12±9.75)d,假体周围骨折组为(38.41±12.43)d,假体周围感染组为(31.79±7.39)d(F=13.74,P<0.01);Harris髋关节评分假体无菌性松动组从术前的(46.89±8.63)分提高至末次随访时的(85.76±6.48)分,差异有统计学意义(t=24.43,P<0.01);假体周围骨折组从术前的(45.90±7.98)分提高至末次随访时的(83.90±6.27)分,差异有统计学意义(t=17.16,P<0.01);假体周围感染组从术前(48.12±7.22)分提高至末次随访时的(88.67±5.79)分,差异有统计学意义(t=10.73,P<0.01);各组间末次随访评分(F=1.44,P>0.05)无明显差异。患者术后切口均Ⅰ期愈合,无下肢深静脉血栓及坐骨神经损伤等并发症出现。随访期间假体周围可以看到明显的骨长入,无假体松动和感染者,植骨处无明显骨吸收及假体下沉。[结论]使用生物型翻修加长柄行人工髋关节翻修术,早期疗效满意,能明显改善髋关节功能,但远期疗效有待进一步观察。
