髋关节置换术后人工假体周围早期骨量变化的连续观察(1)
【摘 要】目的:探讨髋关节置换术后人工假体周围早期骨量变化的连续观察;方法:回顾性分析我院收治的86例髋关节置换术后患者作为研究对象,患者均进行X线骨密度检查。采用Wilkinson 4区(R1、R2、R3、R4)评价髋臼假体区,采用Gruen法(ROI①、②、③、④、⑤、⑥、⑦)测定股骨柄假体区。比较患者健侧与上述各区域骨量的变化差异;结果:术患侧术后12周、24周、48周髋臼R1、R2、R3区域骨密度显著低于健侧(p<0.05);患侧术后12周、24周、48周股骨ROI①、②、③、⑥、⑦区域骨密度显著低于健侧(p<0.05);结论:髋关节置换术后12-48周患者常伴有不同程度的骨量减少,尤以R1、R2、R3区域、ROI①、②、③、⑥、⑦最为显著,可为临床诊疗提供参考价值。

Close observation on the early bone mass changes of artificial prosthesis after the hip arthroplasty
Abstract Objective: To make a close observation on the early bone mass changes of artificial prosthesis after the hip arthroplasty. Method: The clinical data about 86 patients of receiving the hip arthroplasty was reviewed. All the patients received the X-ray examinations of bone mineral density (BMD). The acetabular components were evaluated through Wilkinson regions (R1, R2, R3, R4); the femoral components were evaluated through the Gruen methods (ROI①, ②, ③, ④, ⑤, ⑥, ⑦). The bone mass of the healthy sides and the above regions were compared. Result: after 12w, 24w and 48w, the BMD of the acetabular R1, R2, R3 was significantly lower than healthy sides (P<0.05);after 12w, 24w and 48w, the BMD in the femoral ROI①, ②, ③, ⑥, ⑦ was significantly lower than healthy sides (P<0.05);Conclusion: After 12-48w of hip arthroplasty, the bone mass is certainly reduced, especially in the R1, R2, R3 and ROI①, ②, ③, ⑥, ⑦. It provides a treatment basis in clinical practice.

人工髋关节置换术是临床上治疗髋臼、股骨近端骨折较为常用的手段之一,其临床效果家,术后恢复也较快,但部分患者存在一定的置換失败[1]。分析和研究髋关节置换术后假体周围骨量的变化[2],有助于为术后诊疗和随访提供一定的参考信息,而目前关于髋关节置换术后假体周围骨量的动态观察研究报道则较少。本文探讨髋关节置换术后人工假体周围早期骨量变化的连续观察,现汇报如下。
1 资料与方法
1.1 一般资料 将2014年10月至2016年11月我院我院收治的86例髋关节置换术后患者作为研究对象。其中男性56例,女性30例;年龄28~76岁,平均(58.5±6.2)岁;股骨柄为非骨水泥钛制柄,髋臼杯为钛制球面臼杯。纳入标准:①患者均符合髋关节置换的手术适应症;②无严重脏器功能障碍者;③单侧髋关节置换术;④患者签署手术知情同意书;⑤无精神异常者;⑥本研究经医院伦理委员会批准;⑦无自身免疫系统疾病者;排除标准:①凝血功能障碍者;②严重的重要脏器功能障碍者;③患者未签署手术同意书;④临床资料缺失或不详细者;⑤精神异常者;⑥合并股骨、髋臼恶性肿瘤疾病菏者;⑦合并自身免疫系统疾病者;
1.2 方法 患者患侧髋关节均进行改良Gibson切口,依次切开皮肤、皮下组织及深筋膜。使髋关节后侧及大转子充分暴露。同时切开关节囊并暴露髋臼,其分离和切除瘢痕组织,评价骨缺损类型及内固定位置等,植入非骨水泥压配型假体。术后1天制动,术后5天坐起,两周后负重行走,负重初始重量为20kg,24周后完全负重。采用美国Lunar公司生产的X线骨密度仪器测定患者骨密度,髋臼假体周围采用Wilkinson 4分法:界沿闭孔内缘垂直向上,外界沿股骨假体外侧垂直向上,水平线设定上下界限。假体髋臼评分为R2、R3区,RI区为R2区上平移3.6cm,R4区为R3下平移3.6cm。股骨柄周围按Gruen法分为7个感兴趣区(ROI):假体粗隆至远端平分为3段,远端2cm区域为4区。假体外侧由上至下分为1区、2区、3区,内侧由下至上为5区、6区、7区。术后1周、术后12周、24周、48周通过骨密度仪器测定患者骨密度。, http://www.100md.com(冯敬桃 黄岳 杨勇)
