【摘要】：目的 探讨Tri-Lock骨保留型股骨柄假体在中青年全髋关节置换术中应用的短期临床效果。方法自2011年03月至2013年08月,收集采用Tri-Lock骨保留型股骨柄假体进行全髋关节置换术的病例19例(19髋)。取后外侧股骨大粗隆后缘切口,50°截断股骨颈,取出股骨头,修整股骨颈,使用髓腔锉股骨远端扩髓。扩臼至能完全容纳下臼杯,待彻底止血后置入人工臼杯。置入Tri-Lock标准头颈,应用C型臂X线机透视确定标准头颈试模位置、松紧度、活动度以及稳定性,取出试模后,安装陶瓷颈后复位。结果本组切口长度(9.3±1.5)cm,术中出血量(300.0±141.0)ml。19例均获得随访3~31(19.5±8.0)个月,术后无感染、下肢深静脉血栓、关节脱位、异位骨化、假体松动移位等并发症发生。末次随访时疼痛均解除,双下肢等长,无跛行,髋关节屈曲度70°~110°。术前髋关节功能Harris髋关节功能评分(58.4±18.6)分,末次随访时提高到(97.3±3.9)分,各分项及总分差异均有极显著的统计学意义(P0.01)。术前双侧股骨偏心距差值为(4.9±2.9)mm,术后为(2.0±1.7)mm,差异有极显著的统计学意义(t=3.76,P0.01)。结论Tri-Lock骨保留型股骨柄假体在中青年全髋关节置换术中应用的短期临床效果满意。除了提高骨量保留,Tri-Lock骨保留型股骨柄假体还可以应用于股骨远端病变或Dorr A型股骨的患者。
[Abstract]:Objective to investigate the short-term clinical effect of Tri-Lock bone-conserved prosthesis for total hip arthroplasty in young and middle-aged patients. Methods from March 2011 to August 2013, 19 patients (19 hips) underwent total hip arthroplasty with Tri-Lock bone reserved prosthesis. The femoral neck was cut off at 50 掳, the femoral head was removed, the femoral neck was repaired, and the distal end of the femur was reamed with a pulp cavity file. Extend the acetabulum to fully accommodate the bottom cup, after hemostasis, place the artificial cup. Tri-Lock standard head and neck were inserted, and the position, tightness, activity and stability of the standard head and neck were determined by using C arm X-ray machine. After the mould was removed, the ceramic neck was installed and reset. Results the incision length (9.3 卤1.5) cm, intraoperative bleeding volume (300.0 卤141.0) ml.19 patients were followed up for 30.31 (19.5 卤8.0) months. There was no infection, deep vein thrombosis, dislocation of joint, ectopic ossification. Complications such as prosthetic loosening and displacement occurred. At the last follow-up, the pain was relieved, the lower limbs were equal in length, there was no claudication, and the flexion of hip joint was 70 掳~ 110 掳. The hip function score of Harris before operation was (58.4 卤18.6), and it was increased to (97.3 卤3.9) at the last follow-up. The difference of eccentricity of bilateral femur was (4.9 卤2.9) mm, and (2.0 卤1.7) mm, respectively (t = 3.76, P 0.01). Conclusion the short-term clinical effect of Tri-Lock bone-conserving prosthesis for total hip arthroplasty is satisfactory. In addition to improving bone retention, Tri-Lock bone reserved prosthesis can also be used in patients with distal femoral lesions or Dorr A femur.
