    The Küntscher Y-nail is a two-piece intramedullary device used in the management of unstable trochanteric fractures. The Y-nail consists of a Küntscher intramedullary nail and a fenestrated femoral neck component. This device offers distinct biomechanical and clinical advantages when compared with the compression hip screw, blade-plate device, or other intramedullary fixation.

    This retrospective study evaluated 137 patients with unstable fractures of the hip. Results were evaluated by specific criteria: pain, extremity shortening, range of motion, deformity, and ambulatory status. Management with the Y-nail resulted in 36% excellent, 44% good, 16% fair, and a 4% poor result. Clinical experience with this technique resulted in a short operative time, limited blood loss, decreased soft tissue trauma, and early patient ambulation.

    The Küntscher Y-nail may provide a favorable alternative to other methods used for stabilization of fractures of the proximal femur.
