Clinical evaluation of the Alta hip bolt in peritrochanteric hip fractures.
We reviewed the clinical and radiographic results of 58 patients with peritrochanteric fractures treated with the Alta hip bolt (a sliding compression device that inserts a dome plunger in the femoral head instead of a hip screw). This group was compared with a group of 53 patients treated with conventional hip screws. Three patients (5.2%) treated with the Alta hip bolt and three patients (5.7%) treated with conventional hip screw had failure of fixation. Failure of fixation consistently occurred in patients with unstable fracture patterns or significant osteopenia. There were no cases of bolt cut-out in stable intertrochanteric fractures. We conclude that the Alta hip bolt performs as well as sliding hip screws in peritrochanteric fractures, but the additional learning curve and increased cost do not justify its routine use at this point in time.
