Infracaput fracture of collum femoris in the youth is usually caused by tremendous violenceand characterized by obvious translocation and high ratio of ischemic necmeis of femoral head. Artificialfemoral head replacement or hip replacement is not suitable for the youth. Twenty-eight cases of suchfracture were treated with implantation of quadrate muscle of thigh with bone flap combined with internalfixation by screw,and a follow-up Period of 8 ~ 36 months was carried on. The results showed that allcases resulted in a bony union and ischemic necrosis of femoral head did not occur.It is suggested thatthe opelation should be Performed as early as possible to restore the blood circulation of femoral head,and proper reduction and firm internal fixation guarantee the union of fracture,Quadrate muscle of thighwith bone flap has a rich blood supply and operation can be accomplished in the same incision of internalfixation,so that the injury is iess and the successful rate is high.
