伴有僵／强直畸形的炎症性肘关节炎行半限制性人工全肘关节置换术的早期疗效

目的 探讨对合并僵/强直畸形的炎症性肘关节炎患者行半限制性人工全肘关节置换的早期疗效.方法 2008年4月至2010年1月采用Coonrad-Morrey半限制型假体治疗肘部疾患7例（7肘）,其中类风湿关节炎4例,银屑病性关节炎2例,肘关节骨关节炎1例;其中男2例,女5例;年龄41～65岁,平均49.75岁.结果 7例患者均获得随访,肘关节屈伸活动度由术前的52.5°（0°～75°）上升至术后的102.86°（80°～118°）（P〈0.05）;肘关节前臂旋前、旋后的活动范围由术前的71.25°（0°～120°）提高至115°（50°～150°）（P〈0.05）.患者Mayo肘关节功能评分（MEPS评分）由术前的55.63分提高至术后的81.25分（P〈0.05）;3肘优,3肘良,1肘可,优良率85.7%.并发症：1例完全强直肘关节术后1周康复锻炼时出现肱骨内髁骨裂,石膏固定治疗后6周愈合,1肘术前即有尺神经支配区感觉减退,术后6个月尺神经支配区感觉部分恢复.结论 对于合并僵/强直畸形的炎症性关节炎患者行半限制性人工全肘关节置换术的早期疗效较好,具有彻底矫正畸形、消除疼痛,改善肘关节功能的优点,但中长期疗效仍需进一步观察.

The early effects of semi-constraint total elbow arthroplasty for stiff or ankylosed inflammatory arthritis in elbow

Objective To discuss the early effectiveness of semi-constraint total elbow arthroplasty in the treatment of stiff or ankylosed inflammatory arthritis.Methods Seven total elbow replacement procedures were performed with Coonrad-Morrey semi-constraint prosthesis,from April,2008 to January,2010.There were four of the seven cases with rheumatoid arthritis,two with psoriatic arthritis,and one with osteoarthritis.Two of the seven patients were male,and the other five were female.The average age was 49.75 years o...
