- Nonin'lammatory degenerative joint disease including osteoarthritis and avascular necrosis.
- Rheurnatoid arthritis
- Correction of functional deformity
- Treatment of non-union, femoral neck fracture, and throchanteric fractures of the oroximal femur with head involvement, unmanageable using other techniques.
- Revision of previously failed total hip arthoplasty.
All devices are metallic, tapered hip femoral components. Each utlizes a modular ferr oral head component that is taper fit onto the stem at the time of surgery.
The provided document is a 510(k) premarket notification for expanded indications of non-cemented porous coated total hip prostheses. It does not contain information about acceptance criteria, device performance, or any studies using test sets, training sets, or ground truth.
Specifically, the document states under "Clinical and Non-Clinical Testing: None provided." This indicates that no new studies were submitted to support the expanded indications, and the approval is based on substantial equivalence to previously legally marketed devices.
Therefore, I cannot provide the requested information.
§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.
(a)
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.(b)
