Revision of previously failed total joint arthroplasty. 8. Trauma. These devices are to be used with bone cement unless composed of OsseoTi (titanium alloy, not licensed in Canada) or a proximal femur is indicated for use (USA). Biomet OSS Reduced size (RS) components offers a variety of component options for treatment in small adults and adolescents (12-21 years) that require proximal femoral, total femur, or proximal tibial replacement as well as, resurfacing components for the proximal tibia and distal femur (USA). *Not applicable to Regenerex Ultra Porous Construct titanium knee augment usage (not licensed in Canada), or any other knee component. COMPRESS INDICATIONS The Compress Segmental Femoral Replacement System is indicated for: - 1. Correction of revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement. - 2. Tumor resections. - 3. Revision of previously failed total joint arthroplasty. - 4. Trauma. The Compress Segmental Femoral Replacement System components are intended for uncemented use. When components of the Orthopaedic Salvage System are used with Biomet's Compress Segmental Femoral Replacement System, the user should refer to the package insert contained with the Compress components for full prescription information. EXPANDABLE INDICATIONS The Biomet Side Access Distal Femoral Expandable offers a treatment requiring distal femoral replacement who have not yet achieved full skeletal maturity (open epiphysis) or patients who require surgery who have significant residual leg length discrepancy. Indication for use of this device is most commonly turnor resection but could also involve osteoarthritis; theumatoid arthritis; correction of deformity; and correction of unsuccessful osteotomy, arthrodesis or previous joint replacement. The devices are single use implants intended for implantation with Biomet Compress.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

### Device Description

The OSS/Arcos IM Total Femur Rod is, in simplest terms, a metal rod that is inserted into the IM canal of a femur and connects a proximal femoral component to a distal femoral component. The aforementioned femoral components are secured to the rod by both a Morse taper and a screw; the proximal end features an "Arcos" taper while the distal end is an "OSS" taper. The Arcos taper is the same as that utilized by the devices in K090757 while the OSS taper is identical to that utilized by the predicate device.

The rods are slightly bowed to mimic the natural femur and find appropriate alignment. All rods have a diameter of 14 mm and are available in 1 cm length increments from 20 cm to 30 cm.

Image /page/3/Picture/12 description: In the image, a bone is shown with metal attachments on both ends. The bone is long and slender, with a slightly curved shape. The metal attachments are silver and appear to be connected to the bone with screws or bolts. The bone and metal attachments are likely part of a medical device or implant, possibly for orthopedic surgery. The image is well-lit and the details of the bone and metal attachments are clearly visible.

The device is compatible with Biomet's Arcos proximal bodies and OSS distal femoral components.

- 1. Correction of revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement.
- 2. Tumor resections.
- Revision of previously failed total joint arthroplasty. 3.
- 4. Trauma.

The Compress Segmental Femoral Replacement System components are intended for uncemented use.

When components of the Orthopaedic Salvage System are used with Biomet's Compress Segmental Femoral Replacement System, the user should refer to the package insert contained with the Compress components for full prescription information.

epiphysis) or patients who require surgery who have significant residual leg length discrepancy. Indication for use of this device is most commonly tumor resection but could also involve osteoarthritis; rheumatoid arthritis; correction of deformity; and correction or revision of unsuccessful osteotomy, arthrodesis or previous joint replacement.

The devices are single use implants intended for implantation with bone cement or with Biomet Compress.

#### Summary of Technological Characteristics

The new devices are a modification to the predicate device (K033871, K123501) in the following ways:

- The proximal taper geometry is being modified
- The proximal screw packaged with the device is changing

All other technological characteristics remain unchanged.

#### Summary of Performance Data

Mechanical testing in support of the Arcos taper and proximal screw was previously supplied in K090757. These tests were performed on the worst-case Arcos constructs; as the OSS/Arcos IM Total Femur Rod does not present a new worst-case, this testing is sufficient show the subject device is as safe and effective as the predicate.

#### Substantial Equivalence Conclusion

The proposed and predicate IM Total Femur (K033871, K123501) devices have the same intended use and indications for use (K141331, K14050) and Taper Connection References (K912712, K090757). The proposed design changes do not alter the fundamental scientific technology shared by both the proposed and predicate IM Total Femur devices. The information provided in this submission demonstrates that the proposed device is as safe and effective as the predicate and does not raise different questions of safety and effectiveness than the predicate. Therefore, the proposed OSS IM Total Femur Rod is substantially equivalent to the cited predicate device(s).
