文题释义:
Accolade Ⅱ生物型股骨柄:是将假体置入股骨髓腔后,其锥形几何形态设计与股骨近端的髓腔接近,置入后获得理想的骨质填充和压配,通过压缩皮质骨与假体柄间的松质骨,骨量丢失少,从而达到植入物与股骨紧密结合的初期稳定,并且由于成骨细胞的作用,其在股骨柄生物深层长入的过程中主导,为股骨柄的远期稳定提供条件,以及预留的松质骨在一定的应力环境下进一步与假体表面长合,实现假体在股骨中的远期稳定固定。
发育性髋关节发育不良:是一种先天性发育畸形,不同于髋关节炎,其有可能开始于胚胎期软骨原基阶段,因软骨发育障碍或软骨骨化障碍所致。其临床特点是股骨头小并且变形股骨头完全位于臼外,与真臼无接触,头无骨性支持,靠拉长、增厚的关节囊支撑股骨颈:可能短粗,前倾角增大:股骨上段畸形,髓腔狭窄(左右径<前后径)细小,髓腔可能很窄小而影响股骨假体的,大转子后旋。
 
摘要
背景:目前微创短柄的出现,相对全涂层锥形柄来说,有着更优异的股骨髓腔匹配度,极大的降低假体微动的风险。
目的:进一步验证微创短柄AccoladeⅡ在CroweⅠ型发育性髋关节发育不良人工全髋关节置换中的应用效果。
方法:统计分析应用Accolade Ⅱ生物型股骨柄假体人工全髋关节置换治疗16例CroweⅠ型发育性髋关节发育不良患者的临床资料,比较患者关节置换前后的双下肢长度差异变化,同时观察置换前后12周患者疼痛、髋关节功能情况及术后一般状况。
结果与结论:①关节置换前后双下肢长度差异变化有显著性意义(P < 0.05),置换前双下肢等长10例(62%),置换后15例(94%);②关节置换后髋臼外展角41°-54°(平均46.9°);③目测类比评分及Harris 评分显著优于关节置换前;④术中出血量平均147 mL,手术时间平均72 min,住院时间平均7.2 d,⑤关节置换后3个月所有患者恢复良好无并发症;⑥结果表明:应用AccoladeⅡ生物型股骨柄假体的人工全髋关节置换治疗CroweⅠ型发育性髋关节发育不良安全、可靠,置换后髋关节功能恢复良好。

Abstract:

BACKGROUND: Compared with the cone stem, short stem holds good matching with femoral canal, and remarkably reduces the risk of prosthesis loosening.

OBJECTIVE: To further investigate the clinical efficacy of Accolade II stem for Crowe type I developmental dysplasia of the hip.
METHODS: Clinical data of 16 patients with Crowe type I developmental dysplasia of the hip undergoing total hip arthroplasty using Accolade II stem were collected, the length of both lower limbs before and after surgery was compared, and the Visual Analogue Scale, functional recovery of the hip and general conditions were observed at 12 weeks postoperatively. 
RESULTS AND CONCLUSION: (1) The change in length of both lower limbs before and after surgery had significant difference (P < 0.05), and 10 patients (62%) with the same length of both lower limbs before surgery, and 15 cases (94%) after surgery. (2) The postoperative acetablar abducent angle was 41°-54° (average 46.9°). (3) The Visual Analogue Scale and Harris hip scores after surgery were significantly improved compared with baseline (P < 0.05). (4) The intraoperative blood loss was 147 mL on average, the mean operation time was 72 minutes, and the hospitalization time was 7.2 days. (5) All patients recovered well and no complications occurred at 3 months postoperatively. (6) To conclude, Accolade II stem is safe and reliable for Crowe type I developmental dysplasia of the hip, and exhibits good functional recovery of the hip.
