Abstract Objective To investigate the factors related to femoral head necrosis after closed reduction and cannulated screw in the treatment of femoral neck fractures in young and middle-aged patients.Methods 256 young and middleaged patients with femoral neck fracture in our hospital from February 2008 to December 2012 were retrospectively analyzed,All patients were treated with closed reduction and internal fixation with cannulated screws.The factors associated with the femoral head necrosis were analyzed,including age,gender,fracture classification,whether the cyst decompression,operatioval interval time,quality of reduction,postoperative hip joint Harris score,time of full-weight-loading and whether or not to remove the internal fixational.Results All cases were followed up for an average of(32.07±14.69) months.31 cases occurred femoral head necrosis,which accounted for 12.10%.Age,fracture type,operation interval,quality of reduction,postoperative Harris score,total weight-bearing time and whether or not to remove the internal fixationl were found correlated to outcome of a femoral neck fracture.Conclusion Quality of reduction,operational interval time, time of full-weight-loading and f whether or not to remove the internal fixationl are found to have the most significant influence on femoral head necrosis after femoral neck fracture with internal fixation in young and middle-aged patients.
