文题释义:

成人发育性髋关节发育不良为何要了解真臼解剖特点及与假体的对应关系?成人发育性髋关节发育不良发病率较高,主要是由于髋臼不能完全覆盖股骨头,导致生物力学异常,引起髋关节发生半脱位或完全脱位。常规方法主要以人工全髋关节置换为主,但是该方法治疗效果取决于假体放置的精度及生物性能。鉴于髋臼位置的特殊性及骨盆形态的不规则性等,使得患者全髋关节置换围置换期使用计算机辅助技术评价成为可能。如果采用计算机辅助评价成人髋臼发育不良全髋关节置换效果理想,即能够准确的把握真臼解剖特点及与假体的对应关系,帮助患者选择合适的髋臼和假体及髋臼重建方式,提高置换后髋臼的生物性能,具有较高的临床应用价值。

 

背景:目前,全髋关节置换是公认的治疗成人先天性髋臼发育不良首选治疗方法。但是,患者治疗过程中尚缺乏理想的评价方法精确的解决髋臼重建问题。

目的:探讨计算机辅助技术在成人髋臼发育不良全髋关节置换中的评价效果及生物性能研究。
方法:选取长海医院骨关节外科2015年1至8月收治的80例成人先天性髋臼发育不良患者资料进行分析,入选患者均行全髋关节置换治疗,采用随机对照方法将患者分为对照组和计算机辅助技术组,两组置换前均采用CT扫描,计算机辅助技术组采用M3D可视化软件对髋臼部位进行三维重建、测量以及手术预演等,比较两组患者全髋关节置换效果及生物性能。

结果与结论:两组患者置换后均一期愈合。与对照组相比,计算机辅助技术组优良率、治疗后Harris评分、置换后髋臼假体外翻角、前倾角显著高于对照组(P < 0.05),而髋臼杯外展角偏移度以、髋臼杯前倾角偏移度、置换后并发症发生率显著减小(P < 0.05)。结果提示,成人髋臼发育不良全髋关节置换中采用计算机辅助评价效果理想,能够准确的把握真臼解剖特点及与假体的对应关系,帮助患者选择合适的髋臼和假体及髋臼重建方式,提高置换后髋臼的生物性能,具有较高的临床应用价值。

Abstract:

BACKGROUND: Currently, total hip arthroplasty is a recognized and preferred method for treatment of adult congenital acetabular dysplasia, however, there were lack of ideal evaluation methods to precisely solve acetabular reconstruction in the process of treatment.
OBJECTIVE: To investigate the evaluating effects and biological properties of computer aided technology in adult acetabular dysplasia after total hip arthroplasty.
METHODS: The clinical data from 80 patients with adult congenital acetabular dysplasia who received the treatment at Department of Bone and Joint Surgery, Changhai Hospital, Second Military Medical University of Chinese PLA from January 2015 to August 2015 were selected and analyzed. All the enrolled patients underwent total hip arthroplasty. All the patients were randomly divided into control and computer-aided technology groups. CT scanning was conducted in these two groups before replacement. Three-dimensional reconstruction measuring and surgical rehearsal on the acetabular site were conducted using M3D visualization software in the computer-aided technology group. The effects and biological properties of total hip arthroplasty were compared between these two groups.
RESULTS AND CONCLUSION: Patients in these two groups primarily healed after replacement. The excellent and good rate, Harris score after treatment, acetabular component, valgus angle and anteversion in the computer-aided technology group were significantly higher than those in the control group (P < 0.05). The acetabular cup abduction angle offset degrees, acetabular cup anteversion offset degrees, and the incidences of complications after replacement were significantly decreased compared with those in the control group (P < 0.05). These results suggest that the effect of computer-aided evaluation in adult acetabular dysplasia after total hip arthroplasty is ideal, and can accurately grasp the true acetabular anatomical characteristics and the corresponding relationship with the prosthesis, so as to help patients to choose the proper acetabulum and acetabular prosthesis and reconstruction ways and improve the biological performance of acetabulum after replacement, with a high clinical value.
