摘要
目的:评价Wallis装置治疗腰椎退行性疾病的初步临床疗效。方法:对2007年8月至2010年6月接受Wallis棘突间动态稳定装置治疗的48例腰椎退行性疾病患者进行回顾性分析,男30例,女18例;年龄40～68岁,平均54.2岁。单节段病变44例,双节段病变4例;其中L3,44例,L4,540例,L3,4和L4,5双节段4例。采用JOA、Oswestry评分标准进行疼痛及功能评价,采用Odom方法进行疗效评估,并摄X线片进行影像学评估。结果:48例均获随访,时间12～24个月,平均18个月。采用Odom评估标准:优20例,良24例,可4例。JOA评分由术前的(12.4±2.7)分增加到术后12个月的(26.1±2.0)分(P<0.01);Oswestry疼痛功能障碍指数由术前的(14.1±2.9)分降至术后12个月的(5.5±1.8)分(P<0.01)。腰椎侧位X线片显示神经根管高度和椎间隙后高度术前与术后12个月比较均有统计学差异(P<0.01)。结论:Wallis棘突间动态稳定装置可较好地维持相应节段的动态稳定,扩大椎管容积,安全可行,近期疗效满意。
ABSTRACT Objective：To evaluate clinical results of an interspinous stabilization system （Wallis） in treating lumbar de- generative disease in the short-term. Methods：From August 2007 to June 2010,48 patients with lumbar degenerative disease who were treated with interspinous stabilization system, the data of patients were analyzed retrospectively. In all of the 48 cas- es,there were 30 males and 18 females with an average age of 54.2 years （ranged,40 to 68 years）. Forty-four cases were with single segment and 4 cases with two segments. Of them,4 cases were in L3,4,40 cases were in L4.5,4 cases were in L3,4 and L4,5. The radiographic data of patients were analyzed. Clinical effects were evaluated by Japanese Orthopedic Association （JOA） score system and low back pain disability questionnaire （Oswestry） and Odom method. Results：All the patients were followed up from 1 to 2 years with an average of 18 months. According to Odom＇s criteria,20 cases obtained excellent results,24 good, 4 fair. JOA score increased from 12.4±2.7 preoperatively to 26.1±2.0 postoperatively （P〈0.01 ）. Oswestry score decreased from 14. 1 ±2.9 preoperatively to 5.5±1.8 postoperatively （P〈0.01）. The posterior height of intervertebral space and height of nerve root canal increased compared with that of preperative height. Conclusion ：The treatment of lumbar degenerative disease with interspinous stabilization system can obtain satisfactory effects in the near future. It can retain dynamic stable of corresponding segments, expand volume of vertebral canal, and is safe and feasible.
