Instrumented posterior lumbar interbody fusion for patients with degenerative lumbar scoliosis

OBJECTIVE: Surgery for degenerative lumbar scoliosis remains challenging for spine surgeons even with the application of pedicle screw instrumentation. This retrospective study assesses the outcomes of instrumented posterior lumbar interbody fusion (PLIF) for degenerative lumbar scoliosis. METHODS: From April 2000 to April 2004, 26 patients with degenerative lumbar scoliosis were treated with instrumented PLIF. Mean age of the 15 females and 11 males was 64.2 years (range, 51 to 77 y). Clinical and radiographic outcomes were retrospectively reviewed for each case at a minimum follow-up of 2 years (median follow-up, 3 y; range, 2 to 6 y). At final follow-up, patients were classified as "satisfied" or "dissatisfied" according to self-reported outcomes. RESULTS: At most recent follow-up, the average Oswestry Disability Index score was significantly lower than the preoperative score (25.8 vs. 58.0; P<0.001). Twenty (76.9%) patients reported that they were satisfied with their surgical outcomes. The average lumbar scoliosis angles were significantly less than preoperative angles (7.4 vs. 16.5 degrees; P<0.001), resulting in a reduction in mean scoliosis angles of 55.2%. The average angles of lumbar lordosis were significantly higher than preoperative angles (30.1 vs. 22.2 degrees; P=0.001), an increase in mean lumbar lordosis angles of 35.6%. No perioperative deaths or major medical complications occurred. Five patients had adjacent segment degeneration and 4 (80%) of 5 reported dissatisfactory outcomes. Further study is required to identify the etiologies of adjacent segment degeneration and methods for avoiding such degeneration. CONCLUSIONS: Analytical results demonstrate that instrumented PLIF after laminectomy in patients with degenerative lumbar scoliosis is an effective and safe procedure.     

痔上黏膜环切钉合术与Milligan—Morgan术治疗Ⅲ、Ⅳ度内痔2年疗效比较

目的比较痔上黏膜环切钉合术（PPH）与Milligan—Morgan术（MMH）治疗Ⅲ、Ⅳ度内痔的远期疗效。方法按照完全随机分组原则将100例Ⅲ、Ⅳ度内痔患者分别采用PPH（PPH组，42例）和MMH（MMH组，58例）手术，观察并比较两组患者术后的远期疗效差异。结果PPH组与MMH组术后2年比较，在出现肛门溢液（2．38％比20．69％，P=0．007）、皮赘（9．52％比25．86％，P=0．040）和细便（2．38％比18．97％，P=0．027）方面PPH组术后少见，总的并发症发生率（9．52％比25．86％，P=0．040）和总排便功能异常（9．52％比29．31％，P=0．017）方面PPH组术后也少见，两组差异有统计学意义。在痔脱垂复发（14．29％比10．34％，P=0．549）、症状改善满意度（92．86％比87．93％，P=0．636）和总的症状复发（19．05％比25．86％，P=0．424）方面两组差异无统计学意义。结论PPH与Milligan-Morgan术治疗Ⅲ、Ⅳ度内痔的远期疗效无显著差异，但PPH安全、并发症少、对排便功能影响小。     

关节镜在膝关节疾患中的应用体会

目的 总结关节镜诊断和治疗膝关节疾患的临床经验。方法 应用关节镜诊治膝关节疾患87例（93膝）。结果 93膝通过关节镜检查和镜视下手术进一步明确了诊断，综合评分由术有3．8分改善了9．3分，总有效率达94．6％。结论 关节镜对膝关节内疾患的诊断直观，明确，镜视下手术创伤小，并发症少，疗效好。     

糖尿病大鼠膀胱逼尿肌超微结构的改变

目的观察糖尿病大鼠逼尿肌细胞超微结构的改变。方法建立非胰岛素依赖型糖尿病(NIDDM)大鼠模型,利用透射电镜观察其逼尿肌细胞内超微结构,应用Imaginetool图像分析软件检测粗面内质网面积和线粒体密度。结果NIDDM组逼尿肌细胞内单位面积平均(115.28μm2)胞质中粗面内质网面积在大鼠被喂养第4、12、24周分别为(4.376±2.321)μm2、(4.794±2.323)μm2、(5.377±2.318)μm2,较对照组的(0.462±0.316)μm2、(0.468±0.314)μm2、(0.476±0.319)μm2明显扩大(p<0.05),线粒体相对密度分别为(0.996±0.063)、(1.019±0.062)、(1.027±0.064),较对照组的(0.827±0.055)、(0.828±0.056)、(0.830±0.058)明显下降(p<0.05)。结论非胰岛素依赖型糖尿病逼尿肌细胞内质网扩张,提示其合成蛋白质功能增强,可能与糖尿病的逼尿肌收缩亢进、不稳定膀胱的情况有关;而线粒体水肿明显,密度下降,提示逼尿肌细胞能量代谢障碍,是引起逼尿肌收缩功能障碍的始动因素。     

Combined anterior and posterior surgeries in the treatment of spinal tuberculous spondylitis

Methods for the treatment of tuberculous spondylitis still are controversial. The authors treated 32 consecutive patients with a two-stage surgical technique combined with antituberculous chemotherapy for 1 year. After anterior debridement, fusion with autogenous anterior iliac tricortical strut bone graft was done, and in a second stage, posterior instrumentation and fusion with autogenous posterior iliac corticocancellous bone graft was done 11 days (range, 4-22 days) later. Postoperatively, patients were encouraged to ambulate with brace protection as early as possible. Twenty-nine patients were followed up for a minimum of 2 years (median, 4.7 years; range, 2-10 years) of whom 28 patients achieved solid fusion (97%). All patients had improvement of back pain including the only patient with pseudarthrosis. Neurologic deficits completely recovered in 84% (16 of 19) of patients after 3 months. Kyphotic deformity improved in all 29 patients (34.6 degrees versus 17.3 degrees ) with the average correction angle of 17.3 degrees. Clinically, 27 patients had achieved a satisfactory outcome (93%). There were no evident surgical complications. The authors, therefore, recommend a two-stage surgical technique combined with antituberculous chemotherapy to treat patients with severe vertebral body destruction attributable to tuberculosis because of its high success rate and a low complication rate.
