钢丝张力带加环扎治疗髌骨骨折的临床应用

目的分析总结钢丝张力带加环扎在髌骨骨折治疗中的应用，探讨其治疗可行性。方法用钢丝张力带加环扎固定方法治疗髌骨骨折95例。结果随访0．5～3a全部愈合，优良率达95．5％。结论该方法具有操作简便、创伤小、固定牢靠、活动早、康复快等优点，是治疗髌骨骨折的一种新的行之有效有方法。     

截瘫患者髋臼皮质双边征的观察

本文报告了对６０名截瘫病人骨盆平片的观察结果，发现有３５例可在两侧髋臼顶部观察到皮质双线征，作者认为，皮质双线征系脊髓损伤后所发生的废用性骨质疏松的Ｘ线征象，并对其形成的影响因素进行讨论。     

腰椎后部结构切除对腰椎抗压强度的影响

本文测定了9个脊柱功能单位(functional spinal unit,FSU)的抗压强度,结果表明后部结构切除使腰椎抗压强度降低。本文指出手术中应尽量减少对后部结构的破坏,保持腰椎的稳定。     

手术后椎间盘炎

手术后椎间盘炎戴力扬手术后椎间盘炎（ｐｏｓｔｏｐｅｒａｔｉｖｅｄｉｓｃｉｔｉｓ）是脊柱外科手术的一种严重并发症，由Ｍｉｌｗａｒｄ最早于１９３６年报道，发生率在０．１％～４％之间。尽管手术后椎间盘炎比较少见，但由于其临床症状非常严重，常给患者带来极大痛...     

LUMBAR SPINAL STENOSIS. A REVIEW OF BIOMECHANICAL STUDIES

ObjectS. To investigate the biomechanical aspects of etiology, pathology, clinical manifestation, diagnosis and surgical treatment of the lumbar spinal stenosis. Methods. A series of biomechanical methods, such as three-dimensional finite element models, threedimensional kinematic measurement, cadeveric evaluation, and imaging assessment was applied to correlate lumbar biomechanics and lumber spinal stenosls. Surgery of lumber spinal stenosis has been improved. Results.The stresses significantly concentrate on the posterolateral part of the annulus fibrcsms of disc, the posterior surface of vertebral body, the pedlcle, the interarticularis and the beet joints. This trend is intensified by disc degeneration and lumber backward extension. Posterior elcxnent resection has a definite effect upon the biomechanical behavior of lumbar vertebrae. The improved operations proved satisfactory. Conclusion. Stress concentration in the lumber vertebrae is of importance to the etiology of degenerative lumbar spinal stenosls, and disc degeneratkm is the initial key of this process. Than these will be aggravatnd by backward extension. Functloval radiography and myelography are of assistance to the diagnosis of the lumhar spinal stenosls. For the surgcal treatment of the lumber spinal stenosis, destruction of the posterior element should be avoid as far as possible based upon the thorough decmnpression. Maintaining the lumbar spine in flexion by fusion after decorapression has been proved a useftd method. When developmental spinal stenoals is combined with disc herniation, discectoray through laminotomy is recommend for decompression.     

Baumann角的放射学测量及其临床意义

测定了48例2～13岁正常小儿及71例肱骨髁上骨折小儿的Baumann角.结果提示Baumann角与提携角之间存在非常显著的相关性(P<0.01),骨折复位后Baumann角可用来准确地预测提携角,并有效地防止肘内翻畸形的发生.

急性中央颈脊髓损伤

急性中央颈脊髓损伤为最常见的急性颈脊髓不完全性损伤，其主要临床特点是上肢运动功能受累明显而下肢受累较轻或不受累、直肠膀胱功能障碍以及损伤平面以下感觉不同程度损害。作者报告８９例，其中２６例行手术治疗。结果除２例早期死亡外，８７例经随访３个月～１５年，ＡＳＩＡ评分由入院时的平均４１．７分恢复到８３．１分。作者认为，急性中央颈脊髓损伤的诊断应与脊髓完全性损伤、颈椎病、交叉麻痹和Ｃ８神经根损伤相鉴别。一旦证实有致压物或不稳定因素存在时即应及时行手术治疗。急性中央颈脊髓损伤多预后良好。原发损伤严重者及老年患者预后较差。     

瘦素缺乏小鼠椎间盘退变的组织学观察

目的探讨瘦素在椎间盘退变中的可能作用。方法采用HE染色观察6月龄雄性ob/ob小鼠（瘦素缺乏小鼠）和野生型小鼠（C57BL小鼠）椎间盘的形态学;免疫组织化学检测Ⅱ型胶原、蛋白聚糖的表达;Real-time PCR检测Ⅱ型胶原、Ⅹ型胶原及蛋白聚糖的基因表达。结果与野生型小鼠相比,ob/ob小鼠椎间盘HE染色表现为椎间盘组织的胶原结构紊乱、髓核碎裂、椎间盘高度降低,免疫组化检测显示Ⅱ型胶原、蛋白聚糖表达减少,Real-time PCR检测显示Ⅱ型胶原、蛋白聚糖基因表达下调而Ⅹ型胶原基因表达上调,差异有统计学意义（P〈0.05）。结论活体内瘦素缺乏可能加速小鼠椎间盘退变。
