Device consists of a femoral hip stem manufactured from ASTM F-75 Cobalt-Chromium-Molybdenum alloy. Stem features a sintered porous coating (Porocoat) applied to the entire surface, excluding the tapered stem tip, to facilitate biological tissue ingrowth for fixation. Used by orthopedic surgeons in clinical settings to replace damaged hip joint articulations. Provides patients with increased mobility and pain reduction by replacing the femoral head and neck. Substantially equivalent to previously cleared hip systems based on design, material, and intended use. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Femoral hip stem; material: ASTM F-75 Cobalt-Chromium-Molybdenum alloy; surface treatment: sintered porous coating (Porocoat) for biological fixation; cementless design; semi-constrained; metal/polymer/metal articulation. ## 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 - Porocoat® Prodigy™ Hip Prosthesis ([K931641](/device/K931641.md)) - Vision AML® Hip System ([K953694](/device/K953694.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Porocoat® Prodigy™ Hip Prosthesis K931641 Vision AML® Hip Prosthesis K953694 The AML hip stem is manufactured from ASTM F-75 Cobalt-Chromium-Molybdenum alloy and has a cobalt-chrome-molybdenum alloy bead sintered porous coating (Porocoat®) applied to the stem. The porous coating is applied to the entire stem with the exception of the tapered stem tip region. Total hip arthroplasty is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. 000005 {1}------------------------------------------------ K003800 2 OF 2 # 510(k) Summary (continued) Indications for use: Total hip replacement is indicated in the following conditions: - Severely painful and/or disabled joint from l. osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia. - Avascular necrosis of the femoral head. 2. - Acute traumatic fracture of the femoral head or 3. neck. - Failed previous hip surgery including joint 4. reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. - Certain cases of ankylosis. 5. Based on similarities of design, commonly used materials, identical sterilization processes, the same indications for use and intended use, DePuy believes that the modified AML Hip Prosthesis is substantially equivalent to the FDA cleared Prodigy Hip Prosthesis system (K931641) and the Vision AML Hip System (K953694). #### Substantial equivalence: ## 0000000 {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white logo for the U.S. Department of Health & Human Services.
