These subject devices are provided sterile and designed for single use only, and are intended for use in patients indicated for total hip arthroplasty. The components may be used for primary and revision applications. ## Device Story Trident® Large Diameter Acetabular Inserts are Ultra High Molecular Weight polyethylene liners for hip prostheses. Available in 40mm and 44mm inner diameters to accommodate specific cobalt chrome femoral heads, with additional sizes (28-36mm) compatible with previously cleared femoral heads. Designed for use with Trident® acetabular shells in primary or revision total hip arthroplasty. Provided sterile for single-use. Orthopedic surgeons implant these devices to replace acetabular bearing surfaces, aiming to relieve pain and restore joint motion in patients with disabling hip disease or poor bone stock. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Ultra High Molecular Weight polyethylene acetabular inserts. Thickness ranges from 3.8mm to 12.6mm. Compatible with Trident® acetabular shells and specific cobalt chrome femoral heads. Provided sterile for single use. ## 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 - Trident® Acetabular Inserts ([K033716](/device/K033716.md)) - Inter-Op Durasul Acetabular System ([K002575](/device/K002575.md)) ## Reference Devices - Howmedica Osteonics' cobalt chrome femoral heads ([K061434](/device/K061434.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
