【摘要】 本文报告了一种新型梯形系列加压钢板(TCP)、电测和光弹模型证明TCP的设计符合等强度原理。通过动物实验与等厚薄铜板(ICP—Tn)比较,TCP组骨折愈合率达95％,而ICP—Tn组骨折过半数不愈合。临床应用TCP治疗四肢长骨骨折134例,136个骨折,其中1/31为多段、粉碎骨折。结果全部骨折愈合,功能恢复优良的占98％。更多还原

【Abstract】 Electric measurements and photoelastic models demonstrated that the newly designed trapezoid compression plate system agrees with the principles of identical strength, not only providing a rigid fixation at the fracture site but also ensuring being flexible at both extremities. Immediate aetive movements an early weight-bearing can be taken postoperatively and are able to promote fractured healing and callus formation.Compared with the thinner plate of identical thickness (ICP-Tn)in animal experiments,65% of the fractures fixed with TCP healed, but nonunion resulted in more than half of the fractures fixed with ICP-Tn. The disturbance of blood supply and bone structure recovered perfectly at 12 weeks following plate fixation. Form Feb 1982 through 1987,136 fractures (134cases) of long bone of the extremities were treated with TCP, 1/3 of which were multiple or comminuted fractures, all fractures healed satisfactorily, with fnnction of the affected legs restored excellently and well in 98%. Complications occurred only in 6.5% of the cases.更多还原
