儿童股骨颈骨折是一种不常见的骨折,发生率较低,受伤机制主要是直接暴力传达到股骨颈导致其骨折。因儿童还处于生长发育阶段,骨骺还未闭合,骨折本身及内固定材料都会在一定程度上带来损伤,预后除了考虑股骨头坏死,还应考虑骺板损伤后的生长发育障碍。国外文献报道,应用钛空心拉力螺钉治疗儿童股骨颈骨折,股骨头坏死的发生率为4%～ Femoral neck fracture in children is an uncommon fracture, the incidence is low, the main mechanism of injury is the direct transmission of violence to the femoral neck fracture. Because the child is still in the stage of growth and development, epiphyseal has not closed, the fracture itself and the internal fixation material will bring some damage, prognosis in addition to consider the necrosis of the femoral head, epiphyseal plate injury should also consider the growth and development disorders. Foreign literature, the application of titanium hollow screw treatment of femoral neck fractures in children, the incidence of femoral head necrosis was 4% ~
