The MUTARS® Proximal Femur Replacement System is a modular hip replacement system offering various components that can be combined to replace the hip joint and address major bone defects with various options depending upon the size and location of the defects of each patient. The MUTARS® Proximal Femur System is intended for cemented and uncemented use in total hip arthroplasty or hemiarthroplasty for the following indications: - Proximal femur replacement in oncology cases where radical resection and replacement of bone is required. - Limb salvage procedures including surgical intervention for severe trauma, failed previous prosthesis, and/or oncology indications, where radical resection and replacement of the bone is required. Use of the prosthesis is generally only indicated in skeletally mature patients.
