摘　　要：To the Editor:Osteosynthesis is considered as a standard management for the non-displaced femoral neck fracture in elderly patients,^([1])but some of the patients would suffer from avascular necrosis or non-union after osteosynthesis.It has been demonstrated that the outcome of the salvage procedure after primary avascular necrosis is not reliable.^([2])Therefore,the preoperative detection of the risk factors should be of great significance.The Garden classification system has been the most commonly used to distinguish the severity of femoral neck fracture,but it is mainly focused on the displacement in the coronal plane.Since the integrity of posterior cortex has been demonstrated as an important role in the outcomes of displaced femoral neck fractures,^([3])it is reasonable to investigate the effect of posterior cortex on the non-displaced pattern.Recently,we compared the outcomes after osteosynthesis for nondisplaced femoral neck fractures with and without posterior cortex complete fracture.
