Diagnostic indications include severe hip pain and disabilities due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, slipped capital femoral epiphysis, fused hip, fracture of the pelvis, and diastrophic variant. ## Device Story MAYO Conservative Hip Prosthesis is a modular femoral stem for total hip arthroplasty; replaces hip joint. Features 12/14 Morse-type taper; compatible with modular femoral heads. Collarless, wedge-shaped design; intended for cementless fixation via mechanical press fit into proximal femoral shaft and biological ingrowth into fiber metal pads. Available with or without Calcicoat (HA/TCP) ceramic coating. Modified version of predicate to accommodate smaller patient anatomies. Used by orthopedic surgeons in clinical settings. Provides structural support for hip joint; restores mobility; reduces pain. ## Clinical Evidence No clinical data provided; bench testing only. Engineering evaluations demonstrated equivalence to predicate. ## Technological Characteristics Modular femoral stem; 12/14 Morse-type taper; collarless, wedge-shaped geometry. Fixation via mechanical press fit and fiber metal pads for biological ingrowth. Optional Calcicoat (HA/TCP) ceramic coating. Materials and manufacturing processes identical to predicate. ## Regulatory Identification A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement. ## Predicate Devices - MAYO Conservative Hip Prosthesis ([K030733](/device/K030733.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

21 CFR § 888.3358 | | Predicate Device: | MAYO Conservative Hip Prosthesis, manufactured
by Zimmer, Inc., K030733, cleared May 1, 2003 | | Device Description: | Like its predicate, the modified MAYO Conservative
Hip Prosthesis is a modular femoral stem intended
to replace the hip joint in total hip arthroplasty. It is
identical to its predicate in that it features a 12/14
Morse-type taper and uses the same variety of
modular femoral heads. It differs only in overall
size where the design is intended to address smaller
patient anatomies. As with the predicate, the
proposed stem is collarless, wedge-shaped, and is
designed for use without bone cement. Fixation is
achieved by mechanical press fit into the proximal
femoral shaft and by biological ingrowth into the
fiber metal pads. As with the predicate, the
proposed device is available with and without
Calcicoat ® Ceramic Coating (HA/TCP). | | Intended Use: | The MAYO Conservative Hip Prosthesis is indicated
