Indications for Use

The Porous Titanium Acetabular Shells are indicated for cemented or non-cemented use in total hip replacement in cases of: 1. Noninflammatory 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 using other techniques. 5. Revision of previously failed total hip arthroplasty.

Device Story

Porous Titanium Acetabular Shells are single-use orthopedic implants for hip joint reconstruction. Constructed from porous titanium alloy (Ti-6Al-4V) with a solid titanium rim for reinforcement; sizes range from 52mm to 80mm. Designed for cemented or non-cemented fixation, with optional screw fixation to native bone. Used in clinical settings by orthopedic surgeons during primary or revision total hip arthroplasty. The shell houses commercially available polyethylene acetabular liners, which are cemented into the shell. The device provides a stable acetabular component to restore hip function, reduce pain, and improve mobility in patients with degenerative joint disease or trauma.

Clinical Evidence

No clinical data provided as a basis for substantial equivalence. Bench testing only.

Technological Characteristics

Constructed of porous titanium alloy (Ti-6Al-4V). Features a solid titanium rim for reinforcement and mating geometry. Designed for cemented or non-cemented use with optional screw fixation. Sizes range from 52mm to 80mm in 2mm increments. Compatible with polyethylene acetabular liners.

Indications for Use

Indicated for skeletally mature patients requiring total hip replacement due to noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, proximal femur fractures (non-union, femoral neck, trochanteric), or revision of failed total hip arthroplasty.

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.
