    Cement-free implant sixteen days after surgery. Femoral component is cobalt chromium combined with titanium which induces bone growth into the implant. Ceramic head. Acetabular cup coated with bone growth-inducing material and held temporarily in place with a single screw.

  • Femoral offset in hemiarthroplasty (crop)

    Femoral (neck) offset is defined as the perpendicular distance between the intramedullary or longitudinal axis of the femur and the center of rotation of the native or prosthetic femoral head. An offset of less than 33 mm is associated with hip dislocation.
