Abstract：Objective To compare three different methods in treating displaced femoral neck fracture in young adults.Methods From Jan.2013 to Jan.2015,totally 105 cases of displaced femoral neck fracture were treated in our hospital.In group A,35 cases were treated with open reduction and 3 cannulated screws fixation,cov-ered by the vascularized greater trochanter bone flap.According to Garden classification,19 cases were type Ⅲand 16 cases were type IV.In group B,35 cases were treated with open reduction and 3 cannulated screws fixation,cov-ered by the quadratus femoris muscle pedicle bone flap.According to Garden classification:18 cases were type Ⅲand 17 cases were type IV.In group C,35 cases were treated with closed reduction and three cannulated screws fix-ation.According to Garden classification,19 cases were type Ⅲ and 16 cases were type IV.The healing time of fracture,Harris scoring of hip joint one year after surgery,nonunion fracture,and femoral head necrosis among three groups were observed.Results Three groups were followed up for 24-48 months,averagely 35 months.The healing time of group A was(82.0 ±17.6)days,Harris score of hip joint one year after surgery was(87.5 ±3.6)points, including 1 case of nonunion(2.9%)and 2 cases of femoral head necrosis(5.7%).The healing time of group B was(97.0 ±15.3)days,Harris score of hip joint one year after surgery was(86.3 ±4.8)points,including 3 cases of nonunion(8.6%)and 5 cases of femoral head necrosis(14.3%).The healing time of group C was(109.0 ± 14.5)days,Harris score of hip joint one year after surgery was(86.1 ±3.5)points,including 5 cases of nonunion (14.3%)and 7 cases of femoral head necrosis(20.0%).There were significant differences in the healing time of fracture,the rate of nonunion,and the rate of femoral head necrosis among the three groups(P<0.05).There was no significant difference in Harris score of hip joint one year after surgery among the three groups(P>0.05). Conclusion The treatment of open reduction with 3 cannulated screws,covered by the vascularized greater trochanter bone flap in young adults can remarkably reduce the incidence of nonunion and osteonecrosis of the femoral head.
