文题释义:
双赤道防脱位髋臼假体:属于一种用于髋关节置换操作简便、互换性较好的生物固定型假体,髋臼假体由髋臼杯和髋臼内衬组成,髋臼杯与髋臼内衬之间采用锥度配合,髋臼内衬的内球面的球心设置在髋臼杯的外球面的球心向髋臼杯的外球面的极点方向,内球面的最大直径与外球面的最大直径不重合,髋臼内衬的内球面与髋臼杯的外球面形成“双赤道”结构,球头的包围尺寸大于其半径,二者相配合旋转的表面加大,能更好地起到防止球头脱出髋臼的作用。
生物固定型假体技术:又称无骨水泥的人工全髋关节固定技术,主要适应于骨生长的三维钛丝网状交错表面处理,减少了界面松动的失败。近年,在欧洲和北美洲许多国家已经开始发展髋关节假体采用羟基磷灰石表面喷涂,促进活骨生长,以在金属表面摒除纤维膜生长的干扰,也取得了显著效果。这种假体表面的方式,有利于骨小梁长入和骨-假体界面的稳定,因此有长期稳定的疗效而广泛应用。

 
摘要
背景:针对髋关节置换术后的脱位症状,双赤道防脱位髋臼假体应运而生,其在临床中的应用效果还需进行随访观察来验证。
目的:观察应用双赤道防脱位髋臼假体进行全髋关节置换的早期临床疗效。
方法:从2013年1月至2015年11月对30例患者运用双赤道防脱位髋臼假体行全髋关节置换,并对患者进行术后1年的临床随访观察,根据Harris评分、北京方案评分标准以及影像学评价方法了解患者的髋关节活动功能及松动情况。
结果与结论:①30例患者均获得1年随访;②患者的平均Harris评分由术前的(39.7±3.87)分增加到术后1年随访时的(93.6±3.82)分,平均北京方案评分也由术前的(10.5±2.46)分增加到术后1年时的(17.3±1.87)分,差异有显著性意义(P < 0.05);③假体置换前患者患髋均有中等程度以上的疼痛,术后28例患者髋关节轻度疼痛或无疼痛,2例患者中度疼痛;术后X射线检查显示髋关节稳定;④综上可知,应用双赤道防脱位髋臼假体进行全髋关节置换的短期随访效果令人满意,但中远期疗效还需进一步随访评价。

Abstract:

BACKGROUND: To solve the dislocation following hip arthroplasty, a double mobility acetabular prosthesis has been developed, and its effect still needs to be confirmed through follow-up observation.

OBJECTIVE: To explore the early clinical effectiveness of total hip replacement with double mobility acetabular prosthesis.
METHODS: Thirty patients admitted from January 2013 to November 2015, were given total hip replacement with double mobility acetabular prosthesis, and were then followed up for 1 year. The hip function and loosening were evaluated by Harris hip scores, Beijing program scaling and imaging examination.
RESULTS AND CONCLUSION: (1) All patients were followed up for 1 year. (2) The mean Harris hip score was significantly increased from preoperatively (39.7±3.87) to postoperatively (93.6±3.82), and the mean score of the Beijing program scaling was also significantly increased from (10.5±2.46) to (17.3±1.87) (both P < 0.05). (3) All patients suffered from moderate to severe pain before replacement, and 28 patients complained mild or no pain and 2 patients with moderate pain after operation. X-ray showed a stable hip. (4) To conclude, the total hip arthroplasty with double mobility acetabular prosthesis achieves satisfactory short-term treatment outcomes, but its long-term effect needs to be observed further.
