• Applicant: Biomet, Inc.
• Product Code: LPH · Orthopedic
• Decision Date: Dec 18, 2014
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3358
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The proposed device system is an orthopaedic joint intended to replace the damaged or diseased natural hip joint in total hip or hemi hip arthroplasty to provide pain relief and restore function. The hip system is modular in design, consisting of the subject monolithic, femoral stem along with previously cleared, legally marketed compatible Biomet modular heads and/or acetabular components for total hip or hemi hip arthroplasty.

Device Story

The Echo Bi-Metric Microplasty Hip System is a modular, monolithic femoral stem implant used in total or hemi-hip arthroplasty. It replaces damaged or diseased natural hip joints to provide pain relief and restore function. The device is intended for uncemented, biological fixation. It is used by orthopedic surgeons in a clinical/surgical setting. The system integrates with previously cleared Biomet modular heads and acetabular components. The device features a shortened stem length and rounded lateral shoulder compared to standard designs. It is manufactured using identical processes and materials as predicate devices. Clinical benefit is derived from the restoration of joint function and pain relief in patients with degenerative joint disease, arthritis, or fractures. No software or algorithms are involved.

Clinical Evidence

No clinical testing was conducted. Substantial equivalence was established through bench testing, including range of motion, femoral stem proximal fatigue, femoral stem distal fatigue, and biocompatibility testing for implant-specific instruments.

Technological Characteristics

Monolithic femoral stem; porous plasma spray coating for uncemented biological fixation. Materials and manufacturing processes are identical to predicates (K070274, K090757). Implant-specific instruments are stainless steel with AlTiN or TiN PVD coatings. Modular design for use with existing Biomet heads/acetabular components.

Indications for Use

Indicated for patients with non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) requiring head involvement, and revision of failed total hip arthroplasty. Porous coated components are for uncemented, biological fixation.

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.

Dear Ms. Gantenberg:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

The technological characteristics of the Echo Bi-Metric Microplasty Hip System are the same as those of predicate devices (K070274, K110400 and K050251) in terms of design, material, and principle of operation with the exception of slight modifications as described in this 510(k). Differences include a shortened stem and rounded lateral shoulder when compared to the K070274 primary predicate.

The Echo Bi-Metric Microplasty Hip Stems are proximally fitting, porous coated shortened stems for uncemented, biological fixation. Stem lengths are within the range of legally marketed short stems also cleared for biological fixation. The subject femoral stem utilizes the identical manufacturing processes as the predicates. The subject stem substrate and plasma spray coating are identical to that of K070274 and K090757. The previously cleared, porous plasma spray characterization data on identical substrate was provided in K090757 and used in support of subject 510(k). The subject non-clinical testing was conducted to demonstrate that the differences did not adversely affect safety and efficacy, and to demonstrate substantial equivalence to the predicate components. All testing met or exceeded the established acceptance criteria. This information is detailed below in the Performance (Non-clinical) section. Additionally, Biocompatibility information was provided in support of the implant specific instrument material.
