OTI’s Z Stems are The femoral stems are forged from Titanium. Clinical history and modeling has shown that a Zweymuller Type stem significantly reduces micro-motion when compared to other more conventional designs.

FEATURES AND BENEFITS Rectangular form assures rotational stability by providing a mechanical interlock with the proximal femoral cortical bone. Unique contour that conforms to the shape that approximates the femoral anatomy, providing secure axial positioning of the prosthesis. The calcar arch replicates the natural anatomic shape of the calcar region. The design more closely approximates the natural physiologic loading pattern for maintenance of healthy bone stock. The trochanteric wing provides primary stability by seating within the lateral aspect of the proximal femur. 12/14 taper Can be used in conjunction with CoCr Head or Ceramic Head. Provides a smaller femoral neck diameter allowing increased range of motion and decreased chance of impingement and dislocation. 14 Sizes which can be used for either left or right total hip replacement.
