Intended Use

Cemented or non-cemented total hip replacement in cases of: 1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis 2. Rheumatoid arthritis 3. Correction of functional deformity 4. Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques. 5. Revision procedures where other treatment or devices have failed. The indications for use of the constrained liners compatible with this system are as follow: The devices are intended for general use in skeletally mature individuals undergoing primary and/or secondary revision surgery at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease, or intra-operative instability and for whom all other options to constrained acetabular components have been considered.

Device Story

Regenerex™ RingLoc® + Modular Acetabular Shell is a metallic, hemispherical, modular acetabular component for total hip replacement. Device features Regenerex™ (porous Ti-6Al-4V) coating on exterior fixation surface for bone ingrowth. System utilizes modular polyethylene liner and modular femoral head taper-fitted to femoral stem intra-operatively. Used by orthopedic surgeons in clinical/surgical settings. Provides stable acetabular interface for hip arthroplasty; benefits patients by restoring joint function and stability in cases of degenerative disease, fracture, or revision.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by design verification and validation bench testing.

Technological Characteristics

Metallic, hemispherical, modular acetabular shell. Exterior surface coated with Regenerex™ (porous Ti-6Al-4V). Modular polyethylene liner and femoral head components. Uncemented or cemented application.

Indications for Use

Indicated for skeletally mature individuals requiring primary or revision total hip replacement due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric). Constrained liners indicated for patients at high risk of hip dislocation due to prior dislocation, bone loss, laxity, neuromuscular disease, or intra-operative instability.

Regulatory Classification

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.
