摘要
牵拉骨骺损伤系指牵拉型骨骺在缺血性坏死的基础上又发生骨骺撕脱骨折的复合性疾患。它区别于过去大多数作者所描述的独立存在的骨骺炎或骨骺骨折。本文通过分析５例病例，对该病的损伤原因、发病机理、损伤病理、诊断与防治进行了探讨。
The injury of traction epiphysis is a compound injury, that has avulsion fracture after ischemic necrosis of the epiphysis. It is different from simple epiphysitis or avulsion fracture, in which the pathogenesis,the symptoms, the pathology, the x-ray and the clinical course possess the characteristics of a compound injury. Most of the patients had chronic pain which became worse after an acute traction injury. Traction is the main cause of this disorder. The longer the traction time, the more the frequency and the heavier the intensity,the more serious is the injury.The pathologic changes are:ischemic necrosis of epiphysis, avulsion fracture of epiphysis and proliferated healing. Repeated traction can first induce ischemic necrosis and later lead to fracture easily because the capability against damages decreased. The avulsion fracture often takes place in epiphysial cartilage and calcified layer of epiphysial plate, The injured part enlarged and the bone structure deranged during the proliferative healing process.
