Device Story

Echo Bi-Metric Microplasty Femoral Stem is a monolithic, collarless, straight hip prosthesis; designed to reduce hip pain and restore joint biomechanics/stability. Implanted during primary or revision total hip arthroplasty; used by orthopedic surgeons in clinical/OR settings. Device provides structural replacement for femoral head/neck; porous plasma spray coating facilitates uncemented biological fixation to patient bone. Surgeon selects appropriate stem size to fit patient anatomy; device functions as mechanical support for hip joint. Benefits include restoration of joint function and pain relief.

Technological Characteristics

Monolithic, collarless, straight femoral stem. Material: Ti-6Al-4V (ASTM F136/ASTM F620). Surface: Proximal circumferential porous plasma spray (PPS) coating (ASTM F1580). Instruments: Stainless steel with AlTiN or TiN PVD coating. Sterilization: Sterile, single-use.

Indications for Use

Indicated for patients requiring primary or revision total hip arthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) unmanageable by other techniques.

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.
