Femoral neck fracture caused by trauma is one of the common orthopedic diseases in clinical practice, and its subsequent complications represented by femoral head ischemic necrosis are now one of the main causes of lower limb motor dysfunction in patients. For posttraumatic femoral neck fracture specific injury and repair mechanisms are still unclear, so the understanding of the femoral neck fracture patients after the body of the indicators and clinically for the treatment of the influence on prognosis could be used to predict future outcomes for patients with femoral neck fractures groundwork, and to take appropriate interventions. At present, it is considered that inadequate blood supply to the femoral neck and associated inflammatory reconstructive response are the main mechanisms of traumatic femoral head necrosis, while factors acting on the related mechanisms are considered as possible risk factors. This paper reviews the recent reports on the factors related to necrosis after femoral neck fracture. Factors such as the cause of injury, Garden type and other fracture types, internal fixation and reduction quality are considered as possible risk factors for poor prognosis. |
