颗粒骨打压植骨治疗全髋关节翻修中髋臼侧骨缺损

The Use and Analysis of Parvule-impacted Bone Graft in Revision Total Hip Arthroplasty with Bone Defect of Acetabulum

探讨颗粒骨打压植骨治疗骨缺损在全髋关节翻修中的应用及疗效分析。包容型缺损直接颗粒骨覆盖,使用打压植骨技术;对于非包容型缺损采用钛网覆盖骨缺损,再用松质骨颗粒覆盖,使用打压植骨技术,重建髋关节的正常解剖形态,恢复骨量,安装生物型或水泥性髋臼假体。结果颗粒骨打压植骨在伴有髋臼侧骨缺损的全髋关节翻修术中可有效重建髋臼侧骨缺损,恢复骨量,并能提供良好的早期稳定性,术后短期随访效果良好,但是其远期结果有待于更长时间、更大规模的随访研究。

This study is to investigate the use and analysis of parvule-- impacted bone graft in revision total hip arthroplasty with bone defect of acetabulum. Strike off or grind bone in acetabular fossa until bone surface with cribriform blood. Bone defection of inclusive type was covered directly with morselized bone by impaction bone grafting. For Bone defection of not inclusive type, first we used titanium mesh to cover it ,then covered it with morselized bone by impaction bone grafting in order to reconstruct the hip normal anatomical configuration and restore bone mass, then install biotype or cement type ace- tabulum prothesis. Parvule-- impacted bone graft in revision total hip arthroplasty with bone defect of acetabulum is effec- tive in short--term follow--up, but the final therapeutic effect couldn＇t be determined, because of the lack long term and large amount of follow up study.
