Femoral neck fractures in young adults are not uncommon in clinical work. For fresh fractures or old femoral neck fractures of subcapital type or Garden types III to IV, femoris caput necrosis and nonunion are apt to occur if conventional therapeutic method is adopted and direct joint replacement is attempted. However, this has brought about bitter controversies in medical circles. The authors of this article define such fractures as serious femoral neck fractures. What kind of operational method should be selected, to the maximum extent, to restore the function of hip joints of patients and reduce their complications after operation still remains a problem to be studied. In this article, cases of patients (from 1999 to today) treated with transposition of vascularized greater trochanter bone flap and hollow compression strews are analyzed. Patients were followed for 39 to 84 months, and the results are summarized.
