Indications for Use

The VerSys Beaded FullCoat Calcar Hip Prosthesis is designed to achieve biologic fixation to bone and is indicated for: Total hip replacement for the following: severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head, nonunion of previous fractures of the femur, congenital hip dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, disability due to previous fusion, previously failed endoprostheses and/or total hip components in the affected extremity, and acute femoral neck fractures. Hemi-hip replacement for the following: fracture dislocation of the hip, elderly, debilitated patients when a total hip replacement is contraindicated, irreducible fractures in which adequate fixation cannot be obtained, certain high subcapital fractures and comminuted fractures, secondary avascular necrosis of the femoral head, pathological fractures of the femoral neck, and osteoarthritis in which the femoral head is primarily affected.

Device Story

Modular femoral stem hip prosthesis; designed for biologic fixation to bone. Input: surgical site anatomy. Transformation: mechanical replacement of femoral head/neck. Output: structural support for hip joint. Used in orthopedic surgery; implanted by surgeons. Provides stability and mobility for patients with degenerative or traumatic hip conditions. Modified version of existing system; features calcar region with 10mm and 20mm build-up heights in straight and bowed configurations.

Clinical Evidence

Bench testing only. Finite element analysis performed to demonstrate mechanical equivalence to the predicate device.

Technological Characteristics

Modular femoral stem; Co-Cr-Mo alloy construction; sintered Co-Cr-Mo alloy bead porous surface coating for biologic fixation. Features calcar region with 10mm and 20mm build-up heights. Available in straight and bowed stem configurations. Uncemented prosthesis.

Indications for Use

Indicated for patients requiring total or hemi-hip replacement due to severe pain, disability, arthritis (rheumatoid, osteoarthritis, traumatic, polyarthritis), collagen disorders, avascular necrosis, nonunion of femoral fractures, congenital dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, failed previous implants, or acute femoral neck fractures. Hemi-hip replacement indicated for elderly/debilitated patients where total hip replacement is contraindicated, irreducible fractures, high subcapital/comminuted fractures, or pathological femoral neck 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.

femur, congenital hip dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, disability due to previous fusion, previously failed endoprostheses and/or total hip components in the affected extremity, and acute femoral neck fractures.

Hemi-hip replacement for the following: fracture dislocation of the hip, elderly, debilitated patients when a total hip replacement is contraindicated, irreducible fractures in which adequate fixation cannot be obtained, certain high subcapital fractures and comminuted fractures, secondary avascular necrosis of the femoral head, pathological fractures of the femoral neck, and osteoarthritis in which the femoral head is primarily affected.

The modifications to the VerSys Beaded FullCoat Comparison to Predicate Device: Bowed Revision Hip Prosthesis do not change either the intended use or the fundamental scientific technology of the device. It is packaged and sterilized utilizing the same materials and processes. The modified device is designed to offer another revision style line extension to the existing system of implants.

Performance Data:

Finite element analysis demonstrated that the device is equivalent to the predicate.
