Concomitant displaced vertical neck fracture and unstable 4-part trochanteric fracture in the ipsilateral femur has seen rarely but they can occur on occasions. One such case was seen a 56-year-old male patient with both of those fractures. He underwent dynamic hip screw fixation for intertrochanteric and neck fracture with a candy- packing wiring for reduction of lesser trochanteric fragment. At the 18th month follow-up after surgery, all fracture sites were united with no evidence of avascular necrosis of the femoral head on radiograph and the function of the hip joint was restored without pain. We would report this case with a review of the literature; the anatomical reduction and stable internal fixation are an important factor for a good prognosis in a young patient with concomitant displaced vertical neck fracture and unstable 4-part trochanteric fracture in the ipsilateral femur.
