The Trabecular Metal Modular Acetabular System with a Trilogy Longevity® Constrained Liner is indicated for primary or revision total hip arthroplasties where there is a high risk of hip dislocation due to a history of instability, bone loss, joint, muscle or tissue laxity, or disease condition. This device is intended for patients for whom all other options to constrained components have been considered. This device is intended for either cemented or noncemented use. ## Device Story Modular acetabular cup system for hip joint replacement; replaces damaged hip joint via biological fixation (uncemented) or bone cement. System comprises Tivanium (Ti-6Al-4V alloy) shell with metallurgically bonded Trabecular Metal porous coating and polyethylene liner. Shells available in 38-80mm diameters; options include multiple screw holes, cluster screw holes, or no screw holes for Tivanium alloy screw fixation. Used by orthopedic surgeons in clinical/surgical settings. Provides stable acetabular component for hip arthroplasty; facilitates bone ingrowth for long-term fixation; restores joint function; reduces dislocation risk when using constrained liners. ## Clinical Evidence No clinical data. Substantial equivalence based on non-clinical performance testing, including evaluation of device design and geometry per FDA Guidance Document for Testing Orthopedic Implants with Modified Metallic Surfaces Apposing Bone or Bone Cement (4/28/94). ## Technological Characteristics Modular acetabular shell; Tivanium (Ti-6Al-4V alloy) substrate; Trabecular Metal porous coating; polyethylene liner. Diameter range 38-80mm. Fixation via biological ingrowth (porous) or bone cement. Screw fixation option using Ti-6Al-4V alloy screws. Threaded polar hole for cup positioner attachment. ## 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 - Zimmer Trabecular Metal Modular Acetabular System ([K021891](/device/K021891.md)) - Trilogy Longevity Constrained Liner ([K071718](/device/K071718.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

July 13, 2007. | | Device Description: | The Zimmer Trabecular Metal Modular Acetabular
System is a modular acetabular cup system intended
to replace a hip joint and designed to achieve
biological fixation to bone without the use of bone
cement; or, it may also be for cemented fixation.
The system consists of a shell and polyethylene
liner. The shell substrate is made from TivaniumTM
Ti-6Al-4V Alloy. The outer porous material, which
is metallurgically bonded to the shell substrate, is
made of Trabecular Metal. | | | Three porous acetabular shell designs are available:
one with multiple screw holes, one with cluster
screw holes and one without screw holes. The
shells range in diameter from 38 to 80mm in 2mm
increments. The screw holes permit the use of
Tivanium Ti-6Al-4V Alloy screws for immediate
fixation and security. The shell incorporates a
threaded polar hole to attach the cup positioner. | 11 {2}------------------------------------------------ Page 3 April 26, 2010 Intended Use: The Trabecular Metal Modular Acetabular System with a Trilogy Neutral, Elevated, Offset or Oblique Liner is indicated for primary or revision surgery for rehabilitating hips damaged as a result of Noninflammatory degenerative joint disease (NIDJD) or its composite diagnoses of osteoarthritis, avascular necrosis, protrusio acetabuli, traumatic arthritis, slipped capital epiphysis, fused hip, fracture of the pelvis and diastrophic variant.
