摘要:

背景:生物型股骨假体的固定方式与骨水泥假体相比,没有水泥-假体分离,水泥套破裂,水泥碎屑引起骨溶解的担忧,长期结果优良,并且假体远期生存率较高。

 

目的:观察Accolade TMZF生物型股骨柄假体用于全髋关节置换的近期疗效及并发症。

 

方法:2010年2月至2012年7月采用生物型股骨柄行初次全髋关节置换67例70髋,均采用Accolade TMZF生物型髋关节假体系统,股骨侧假体使用同一款Accolade TMZF生物锥形柄,髋臼侧则采用Secure-fit HA和Trident PSL HA两种髋臼杯行生物学固定。关节头臼摩擦面采用陶瓷-陶瓷组合49髋,陶瓷-聚乙烯组合19髋,金属-聚乙烯组合2髋。置换后根据髋关节影像学资料评估股骨柄假体的生物学固定、假体周围骨溶解及假体下沉情况,并观察髋关节功能、大腿痛及并发症发生情况。

 

结果与结论:全部病例随访均超过2年。由置换前Harris髋关节评分(32.7±6.2)分改善至末次随访时(89.2±5.1)分。末次随访时大腿轻度疼痛4例(6%),无中重度、极重度疼痛。未见患髋因各种原因失败需翻修。X射线片结果示,最终随访时无假体移位或松动现象,股骨侧可见假体周围均为骨性固定,假体下沉< 2 mm者1髋,其余均无假体下沉。术中无血管、神经损伤等并发症出现,但因假体置入时发生股骨距劈裂骨折而采用钢丝环扎4髋。置换后无下肢深静脉血栓形成,无假体周围骨折。提示Accolade TMZF生物型股骨柄用于初次全髋置换的早期疗效满意,可以有效改善髋关节功能。但随访时间较短,中远期疗效需进一步观察。

Abstract:

BACKGROUND: Compared with the fixation of bone cement prosthesis, the fixation of cementless femoral prosthesis does not have the following worries, including cement-prosthesis separation, cement sheath rupture, and cement debris-induced osteolysis. Long-term outcomes are good, and the survival rate is high. 

OBJECTIVE: To observe the preliminary clinical results and complications of total hip arthroplasty with Accolade TMZF cementless femoral stem.
METHODS: From February 2010 to July 2012, 67 patients (70 hips) underwent primary total hip arthroplasty with cementless femoral stem. All patients were treated with Accolade TMZF Biological hip prosthesis system. Femoral component was treated with the same Accolade TMZF cementless femoral stem. Acetabular component was treated with Secure-fit HA and Trident PSL HA. The first mortar joint friction surface was treated with ceramic-ceramic composite in 49 hips, ceramic-polyethylene composite in 19 hips and metal-polyethylene composite in 2 hips. After replacement, hip imaging data were utilized to assess biological fixation of femoral stem prosthesis, osteolysis surrounding the prosthesis, and prosthesis subsidence, and to observe hip function, thigh pain and complications.
RESULTS AND CONCLUSION: All cases were followed up for more than 2 years. The mean Harris hip score was (32.7±6.2) preoperatively, and improved to (89.2±5.1) during final follow-up. During final follow-up, four patients (6%) suffered from slight pain. No moderate and severe pain or extremely severe pain occurred. None of the patients needed second operation due to failure for various reasons. X-ray films showed that no prosthesis displacement or loosening. Bone fixation surrounding the prosthesis was visible at the femoral side. Only one hip had subsidence of less than 2 mm, and the remaining did not experience subsidence. No blood vessels or nerve injury appeared during the surgery. During prosthesis placement, femoral calcar cleavage fracture occurred in 4 hips, so wire cerclage was used. Deep vein thrombosis in the lower limb or fractures surrounding the prosthesis was not found after placement. These results indicated that the preliminary clinical results of primary total hip arthroplasty with Accolade TMZF cementless femoral stem are encouraging, can effectively improve the function of hip joint. But the follow-up time is shorter, mid-term long-term curative effect should be further observed.
