Treatment evaluation of 82 cases of femoral neck fracture in youths and the middle-aged

Objective [WT5”BZ]To observe the relation between start time of weight carrying and ischemic necrosis of femoral head, femoral neck fracture and reduction quality in youths and the middle-aged. Methods Of 82 cases with an average age of 36.4 years (21-50 years), 25 cases were with fracture under the head, 36 cases were by the neck and 21 the bottom of head. All cases were treated by single compression screw. Sixty-one cases were treated by uniting musculus quadratus femoris or sartorius muscle-bone flap. Patients were immobilized for 12 weeks after operation and were followed up for average 4 years and 2 months. Results In 5 cases, 4 had bad reduction and femoral head necrosis. Femoral head necrosis occurred in 5 of 10 starting weight carrying after 3-6 months and in 3 of 67 starting weight carrying after 10-12 months. Conclusions Better fracture reduction ,earlier activities and late weight carrying would decrease the rate of the femoral head necosis in youths and the middle-aged.
