The OMEGA "HA" Coated Total Hip System is indicated for use in total or partial hip replacement procedures for patients suffering severe pain and disability due to structural damage in the hip joint from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, traumatic and non-union of femoral fractures. Use of the prosthesis is also indicated for patients with congenital hip dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, and disability due to previous fusion, where bone stock is inadequate for other reconstruction techniques.
Not Found
This document is a 510(k) clearance letter from the FDA for the OMEGA® HA Coated Total Hip System. It confirms that the device is substantially equivalent to legally marketed predicate devices. However, this letter does not contain any information about acceptance criteria, device performance from a study, or details about such a study.
The letter explicitly states:
"You may not label or in any way promote these devices for "enhanced clinical or radiographic performance, enhanced biological fixation and/or long-term stable fixation." The data presented support equivalence with no additional claims over a conventional porous coated hip prosthesis (i.e., biological fixation, only)."
This indicates that the FDA's decision was based on demonstrating equivalence, not on specific performance metrics or clinical study results that would typically be described with acceptance criteria. The clearance seems to be based on the composition and design, assuming similar performance to existing conventional porous coated hip prostheses.
Therefore, I cannot provide the requested information from the provided text as it is not present in the document.
§ 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)
