Abstract:
Objective To find out factors related to avascular necrosis (AVN) of femoral head through a retrospective study of patients with femoral neck fractures treated with cannulated screws.Methods Two hundred and thirty cases of femoral neck fracture whn had been treated with cannulated screws in our department from August 1994 to October 2003 were analyzed statistically.Six factors of patient,age,gender,fracture type (Garden clas- sification),reduction method (close or open),the quality of reduction (Garden Index) and time interval from injury to surgery were analyzed statistically with rank sum test and logistic multiple regression.Results Factors that might have an impact on avascular necrosis of femoral head were ranked in the following likelihood sequence: fracture type,quality of reduction,reduction method,time interval from injury to surgery and age.Gender was found to have little impact on the prognosis of femoral neck fracture (P＞0.05).Conclusions Fracture displacement is the most critical factor that influences the prognosis.Anatomical reduction (close or open) must be achieved to re- duce the risk of AVN.Timing of surgery shows its importance.High age will not lead to an increased incidence of AVN.
