Read the full statement (142 words)

The Global Modular Replacement System (herein referred to as the GMRS) is intended to be used with the components of Howmedica Osteonics' Modular Replacement System, Modular Rotating Hinge Knee System, and/or Kinematic Rotating Hinge Knee System in situations where replacement of extensive bone loss in the femur and/or proximal tibia is required. The Proximal Femoral Module and Distal Femoral Module of the GMRS may be used together, or with the components of the MRS, in replacement of the total femur. Indications and contraindications for this type of replacement are listed below:

Femoral and/or proximal tibial replacement and total femoral replacement in Omology cases where radical resection and replacement of bone is required, and in limb salvage procedures where radical resection and replacement of bone is required. Limb salvage procedures would include surgical intervention for severe trauma, failed previous prosthesis, and/or Oncology indications.

Indications for use as stated in the FDA summary.
