Intended Use

The Apex Hip System is intended for primary or revision total hip replacement. The femoral hip stems and acetabular cup are intended for uncemented fixation and single use implantation. These prostheses may be used for the following conditions, as appropriate: Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Congenital dislocation; Revision procedures where other treatments or devices have failed; Femoral neck and trochanteric fractures of the proximal femur.

Device Story

Apex Modular Head is a prosthetic component for total hip replacement systems; provides +10.5mm offset option for 28, 32, 36, and 40 mm head diameters. Manufactured from wrought cobalt chromium; utilizes standard taper design. Intended for uncemented fixation in primary or revision hip arthroplasty. Implanted by orthopedic surgeons in clinical/hospital settings. Device restores joint function and stability in patients with degenerative joint disease, fractures, or deformities. Benefits include improved anatomical fit and joint mechanics via increased offset options.

Clinical Evidence

No clinical studies were performed. Evidence is based on bench testing: ROM analysis (ISO-21565-2007), finite element analysis (ISO-7206-4), and fatigue strength testing (ISO 7206-6, ASTM F2068-09).

Technological Characteristics

Wrought cobalt chromium per ASTM F1537. Size N taper bore per ASTM F1636-95. Head diameters: 28, 32, 36, 40 mm. Offset: +10.5 mm. Sterilization: Ethylene oxide (SAL 10^-6).

Indications for Use

Indicated for patients requiring primary or revision total hip replacement due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, congenital dislocation, failed prior treatments, or femoral neck/trochanteric fractures.

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.
