The femoral neck fracture having concomitant fracture of the femoral shaft occurs predominantly in young man and have known to associate the serious complication. Coexisting fracture of base of femur neck may be overlooked because either it is undisplaced or original roentgenogram does not include hip. We analyzed the 13 cases of ipsilateral femur neck and shaft fracture who were treated at the Orthopedic department of Soon Chun Hyang University Hospital from Jan., 1983 to Aug., 1988. The result of femur neck and shaft fractures are different from simple femur neck fractures, 1. more common in male (77%) 2. young age (77%) 3. more stronger external violence 4. fracture level is baso-cervical (85%) The operations were delayed about 16.5 days due to multiple trauma. In initially neglected 2 cases of neck fractures (base of the neck) of ipsilateral femur neck and shaft fractures were found at 4 weeks and 6 weeks after trauma, these cases operated with multiple pinning and deformity and avascular necrosis of femoral head was not developed. Two cases of nonunion were developed and these cases fracture level were subcapital and transcervical. Nonunion were treated with Meyer muscle pedicle bone graft, and union was achieved. Avascular necrosis was not develped in our cases. Through this observation it is stressed that early discovery and level of the fracture, which is related to prognosic factor of healing.
