摘要:

背景:假体摩擦界面是全髋关节研究的热点,然而聚乙烯的磨损微粒可诱导炎症反应使假体周围骨溶解并导致假体松动。为了减少聚乙烯的磨损,一方面选择陶瓷对陶瓷、陶瓷对聚乙烯的摩擦界面,另一方面选择更高强度的高交链聚乙烯材料。在年轻活动量大的患者中,陶瓷头的应用是一大进步。
目的:评估大直径氧化铝基复合陶瓷(BIOLOX® delta)球头对第3代高交联聚乙烯(Trident X3, Stryker, Mahwah, NJ)全髋关节在年轻患者中的安全性,并在最短2年的随访后对高交联聚乙烯的磨损率进行放射学测量。
方法:纳入解放军455医院2008年7月至2010年6月收治的30例(32髋)60岁以下非骨水泥全髋关节置换患者,采用36 mm BIOLOX® delta陶瓷球头 (CeramTec,Plochingen,Germany)对高交联聚乙烯的全髋关节,应用Roman软件(Robert Jones & Agnes Hunt Orthopaedic Hospital,Oswestry, United Kingdom)进行磨损分析。患者平均年龄(56.8±6.5)岁。
结果与结论:随访2-3.7年,无关节脱位、球头碎裂或任何关节松动和骨溶解的影像学证据。平均 Harris评分由置换前的(19.9±7.3)分(11-36分)提高到置换后6个月的(35.3±5.4)分。置换磨合期后的平均磨损率为(0.022±0.11) mm/年。提示年轻患者使用大直径陶瓷球头对高交联聚乙烯全髋关节有更高的安全性,即出现关节脱位、假体碎裂、磨损率更低。

Abstract:

BACKGROUND: Prosthesis friction interface is a hot focus in the study of total hip joint. Polyethylene wear particles induced inflammatory reaction, resulting in osteolysis surrounding the prosthesis and prosthesis loosening. To reduce polyethylene wear, ceramics-ceramics and ceramices-polyethylene friction interfaces were selected. High cross-linked polyethylene material with high intensity was selected. In young patients with large activity amount, the application of ceramic head is a great progress.
OBJECTIVE: To assess the safety of large-diameter alumina ceramic matrix composites (BIOLOX® delta) ball on third-generation highly cross-linked polyethylene (Trident X3, Stryker, Mahwah, NJ) total hip arthroplasty in young patients, and to perform radiological measurements of high cross-linked polyethylene wear rate in the shortest two years after follow-up.
METHODS: From July 2008 to June 2010, wear analysis of 30 cases aged less than 60 years with 32 hips with 36-mm BIOLOX® delta ceramic femoral heads (CeramTec, Plochingen, Germany) on highly cross-linked polyethylene was performed in the 455 Hospital of Chinese PLA using Roman software (Robert Jones & Agnes Hunt Orthopaedic Hospital, Oswestry, United Kingdom). The mean age of patients was 56.8 ± 6.5 years. 
RESULTS AND CONCLUSION: Follow-up was conducted from 2 to 3.7 years old. There were no imaging evidences, such as dislocation, the ball head fracture or joint loosening or osteolysis. Mean Harris score was  increased from (19.9±7.3) (11-36) before replacement to (35.3±5.4) at 6 months after replacement. The mean wear rate was (0.022±0.11) mm/year after run-in period. These data indicated that large-diameter ceramic head articulation against highly cross-linked polyethylene in young patients would have high safety for joint dislocation, prosthesis fragmentation and low wear rates.
