To analyze diagnostic process and clinical data in cases of fracture of the femoral shaft with fracture of the proximal femur.

We reviewed 24 cases of patient who undergone surgery for fracture of the femoral shaft with ipsilateral fracture of the proximal femur and more than 1 year of examination of follow up was available. Age, sex.location and classification of the fracture, the time of diagnosis and operation, the method of operation, the associated injuries, the time of bony union and complication were investigated, postoperative function was evaluated on Friedman and Wyman criteria.

Bony union showed significant difference in the displacement and comminution of fracture, postoperative function revealed significant difference according to the associated injuries. The 6 cases (25%) out of 24 cases are failed early diagnosis, 4 cases out of 6 cases was detected during operation and 2cases was found after surgery. 21 cases out of 24 cases of femoral shaft fractures showed union, 23 cases out of 24 cases of femoral neck fractures showed union. There were eleven good, eleven fair, and two poor functional result according to Friedman and Wyman criteria.

Precious clinical and radiologic examination is needed not to miss the diagnosis of proximal femur fractures in ipsilateral femoral shaft fractures with proximal femur fractures. Anatomical reduction and rigid fixation of proximal femur are important to reduce avascular necrosis of femoral head and nonunion of proximal femoral fractures.
