Objective. To observe the effects of closed reduction and pereutaneous K-wires fixation of displacd supracondylar humnerus fracture in children. Methods. Retrospective review of fourteen patients who sustained displaced supmcondylar fracture of distal humerus treated by closed reduction and percutaneous K-wires fixation. Results. All patients' K-wires were removed at 4 weeks post-operation. Their elbow function regained at 8weeks. The average period of followed up was 10 month (varies from 6 to 18 month), all fractmes healed very well without any permanent complications. Two transient nerves palsy, ulnar and radial nerve each, recovered completely at12 weeks and 16 weeks post-operation respectively. Conclusion. Closed reduction and percutaneous K-wires fixation is a safe and efficient treatment for displaced humerus surpracondylar fracture in children.

先天性髋脱位治疗后股骨头增大
本文报告先天性髋脱位治疗后155例.平均随访6.7年,发现股骨头直径比对侧大15%以上者34例,开始治疗年龄在5岁以下者占94%,手术治疗比保守治疗发生率高10倍,其中骨盆截骨术占头大组的91.2%,股骨头形态正常者为85.3%,髋臼发育与正常相比无明显差异.其机理系在髋关节发育高峰期,手术促进了股骨近端血运,刺激了骨骺软骨生长.

闭合复位经皮锁定加压钢板内固定治疗老年肱骨近端粉碎性骨折
肱骨近端粉碎性骨折多见于老年人,由于常伴有骨质疏松,因此低能量损伤即可引起粉碎性骨折.随着对该病认识的不断加深,其治疗也不断发展,锁定加压钢板(locking compres-sion plate,LCP)技术的应用使得肱骨近端粉碎性骨折的愈合率大大提升.

Objective: To improve the results of the treatment of unstable types of intertrochanteric fractures of the femur (ITFF) by internal fixation.Methods: A L-trapezoid compression plate system (L-TCP) was designed and compared to the AO/ASIF angle plates of 95° and 130° (L-AP) with mechanical tests. An Evans Type Ⅲ model was made, the simulation electrical test with loading on single and both legs were done. The results demonstrated that the stability of the L-TCP fixation was significantly greater, and the stress concentration at the upper screw hole was relevantly smaller than that of L-AP. From June 1986 to June 1998, 82 patients of ITFF were treated with L-TCP fixation. The average age was 67.4 years old (26-91). Seventy-four of those fractures were unstable. Fifty-eight patients were treated with open reduction, and 24 cases were treated by closed reduction and limited open (only lateral aspect of upper femur was exposed) fixation with L-TCP under X-ray monitoring.Results: Sixty-six patients were followed up for 6-69months. Complications, including 3 wound infection, 1 non-union, 3 coxa varus and 2 implant breakage (9complications of 7 cases ), all occurred in the open reduction group. No complication was found in the dosed reduction group.Conclusions: In the treatment of ITFF, the results of closed reduction and limited open fixation with L-TCP is significantly better than that of open reduction and fully exposed fixation.
