Intended Use

Total hip replacement is indicated in the following conditions: 1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia. 2. Avascular necrosis of the femoral head. 3. Acute traumatic fracture of the femoral head or neck. 4. Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. 5. Certain cases of ankylosis.

Device Story

DePuy M-Spec 36mm Femoral Heads are orthopedic implants designed as a line extension to existing femoral head product lines. These devices provide additional taper sizes and offsets to increase surgeon flexibility in matching femoral hip stems during total hip arthroplasty. The heads are manufactured from cobalt-chromium-molybdenum alloy and are designed to mate with femoral hip stems featuring matching neck taper sizes (12/14, 11/13, or 14/16). By offering various offsets, the device allows for precise lateralization of the hip joint. The implants are intended for use by orthopedic surgeons in a clinical/surgical setting. The device benefits patients by restoring joint function and reducing pain associated with degenerative or traumatic hip conditions.

Clinical Evidence

No clinical testing was required to demonstrate substantial equivalence. Evidence is based on non-clinical dimensional analysis.

Technological Characteristics

Material: Cobalt-chromium-molybdenum alloy. Head diameter: 36mm. Taper styles: 12/14, 11/13, and 14/16. Offsets: Various configurations ranging from -3mm to +15.5mm. Sterilization: Gamma radiation.

Indications for Use

Indicated for patients requiring total hip replacement due to osteoarthritis, traumatic/rheumatoid arthritis, congenital hip dysplasia, avascular necrosis, acute traumatic fracture of the femoral head/neck, failed previous hip surgery, or ankylosis.

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.
