自体混合植骨治疗成人髋臼发育不良髋臼骨缺损

Autologous mixed bone grafting for the treatment of adult acetabular dysplasia acetabulum bone defect

目的探讨全髋关节置换术中自体骨颗粒、骨泥混合植骨治疗成人髋臼发育不良髋臼骨缺损的临床效果。方法对59例(66髋)CroweⅡ~Ⅳ型髋关节发育不良髋臼骨缺损患者在行全髋关节置换术中应用自体骨颗粒、骨泥混合植骨。结果患者均获得随访,时间1~3年。术后6个月患者Harris评分由术前(48.76±7.79)分提高至(92.09±3.61)分,差异有统计学意义(P<0.001);其中优56髋,良8髋,可2髋,优良率为96.97%。结论自体骨颗粒、骨泥混合植骨治疗成人髋臼发育不良髋臼骨缺损,手术时间短、出血量少,植骨均可愈合,疗效确切。

Objective To investigate the effect of autologous bone particles, mixed bone cement bone grafting in total hip arthroplasty for the treatment of adult aeetabnlar dysplasia bone defect. Methods Autologous bone particles, mixed bone cement bone grafting were used in the 59 cases （66 hips） of Crowe type 1] - IV adult acetabular dyspla- sia with bone defect,who underwent total hip arthroplasty. Results All patients were followed up for 1 - 3 years, Harris scores increased from 48.76 ± 7. 79 preoperatively to 92.09 ± 3.61 at postoperative 6 months, the difference had statistical significance（ P 〈 0. 001 ） ;the results showed that the excellent was in 56 hips, good 8 hips, fair 2 hips, excellent-good rate was 96. 97%. Conclusions Autologous bone cement and bone particles bone graft in the treatment of adult acetabular dysplasia acetabnlnm bone defect patients are with shorter operation time, less blood loss, bone graft is healed, the curative effect is accurate.
