胸腰椎稳定性重建方法的改进

为了改进胸腰椎脱位的治疗方法，更好地重建脊柱稳定性，设计了一种新的脊柱固定器械，由滚花钉及连接板构成，并通过椎弓根进行的一种脊柱后路短节段固定方法，脊柱固定范围限制在两个椎体间。１９８９年～１９９５年，临床应用这种新器械矫正胸腰椎脱位１２例，经１～４年随访，畸形矫正满意，固定牢固。结果表明：该器械具有手术方法简单、固定牢固和手术创伤小等优点。认为，该项技术适用于胸腰椎稳定性的重建。     

张力带固定与钢丝环扎治疗髌骨骨折疗效分析

使用张力带固定、钢丝环扎与丝线环扎治疗髌骨骨折共６５例，平均优良率９１．５２％，但优级疗效者张力带组是８０％，钢丝及丝线环扎组分别是５６％及５６．５％。张力带内固定术后不需石膏外固定，利于膝关节早期功能锻炼与康复，疗效明显优于其它两种疗效（ｐ＜０．０５），但术中操作要求准确细致。与钢丝环扎相比，丝线环扎荷包缝合具有可避免取出内固定的第二次手术的优点，两组疗效相似。     

The use of frame fixation in the management of open distal extensor mechanism avulsion fracture in a dislocated knee

An avulsion fracture of the tibial tubercle is a common injury in traffic accident. If the fracture is closed, then a comparatively good prognosis can be expected through reinforcement of the bone via osteosynthesis and the use of artificial ligaments. In this case, an open wound was observed in the tibial tubercle, and the wound was so polluted that the healing process was significantly delayed. It was therefore difficult to provide simultaneous surgical treatment and so three operations were required to perform the reconstruction of the extensor mechanism. The reconstruction of extensor mechanism and the frame fixation between the patella and tibia was performed. Six months after the injury, the patient was able to walk without aid, had a range of movement from 5°to 130°, and did not show any indications of ADL disorder. Using this method of frame fixation between the patella and tibia proved to be an effective technique for the reconstruction of the open knee extension mechanism injury.

Vertebroplasty and Kyphoplasty in Spinal Trauma

Abstract Kyphoplasty and vertebroplasty have become recognized procedures for the treatment of vertebral fractures, especially in patients with osteoporosis. In most cases of osteoporotic spinal vertebral fracture in elderly patients, polymethylmethacrylate (PMMA) cement is used to fill the defect and stabilize the vertebral body. The techniques of vertebroplasty and kyphoplasty differ in the possibility of realignment and reconstruction of the vertebral body and spinal column. Long-term results in terms of integration of the cement and bioreactivity of the vertebral body are still lacking; so, these procedures are still no options in the treatment of younger patients. Vertebroplasty and kyphoplasty show different success in the management of fresh traumatic spine fractures. The acute traumatic vertebral fracture has to be classified sensitively, to find the right indication for cement augmentation. Mild acute compression fractures can be treated by vertebroplasty or kyphoplasty, severe compression and burst fractures by combination of internal fixation and kyphoplasty. The indications for use of biological or osteoinductive cement in spinal fracture management must still be regarded as restricted owing to the lack of basic biomechanical research data. Such cement should not be used except in clinical studies.     

Cervifix在陈旧性寰枢椎脱位并高位颈髓压迫症中的应用

目的:探讨Cervifix内固定系统治疗陈旧性寰枢椎脱位并脊髓不全损伤的价值。方法:36例陈旧性寰枢椎脱位并脊髓不全损伤行后路融合、Cervifix内固定。男23例、女13例,年龄15～62岁,平均38.3岁。陈旧性外伤21例,先天性畸形9例,类风湿性关节炎伴寰椎前脱位6例。结果:随访8～42个月,平均19个月。术后脊髓功能按JOA17分法评定,改善率为71.4％。全部患者均获骨性融合,内置物无松动、断裂及脊髓损伤加重等并发症。结论:Cervifix内固定可提供坚强有效的节段性固定,提高融合率。同时,可预防单纯减压融合术后早期失稳导致的高位脊髓损伤加重。
