Intended Use

This device is indicated for: Moderate to severe knee instability Significant bone loss and/or ligament deficiencies caused by neoplasms, trauma, rheumatoid arthritis, osteoarthritis, traumatic arthritis, collagen disorders, and/or avascular necrosis of the proximal and/or distal femur and/or proximal tibia Valgus, varus or flexion deformities The salvage of previously failed surgical attempts A total femoral replacement consisting of MOST Options or Segmental proximal femoral, Segmental System segments and Segmental System distal femoral components may be used without cement. Variable Stiffness stem extensions require the use of either a smooth or Trabecular Metal stem collar, which must be cemented to the stem. Following cementing to the stem, the smooth collar must be cemented against the bone. The remainder of the stem must be used uncemented. Fluted stem extensions require the use of either a smooth or Trabecular Metal stem collar, which must be cemented to the stem. Following cementing to the stem extension, the smooth collar must be cemented against the bone. The remainder of the stem must also be cemented against the bone. The Trabecular Metal collar may be used cemented or uncemented against the bone. All other constructs are for cemented use only.

Device Story

Implantable proximal femoral component; replaces proximal femur; manufactured from Tivanium Ti-6Al-4V alloy; features suture holes for soft tissue attachment, proximal male taper for femoral head connection, and distal female taper for segmental system component attachment. Used in orthopedic surgery for reconstruction; intended for patients with severe bone loss or joint instability. Device functions as part of a modular segmental system; allows for cemented or uncemented constructs depending on stem extension type (Variable Stiffness vs. Fluted). Surgeon selects appropriate components based on patient anatomy and clinical need; provides structural support and joint stability; benefits patient by restoring function and salvaging failed previous procedures.

Clinical Evidence

No clinical data was deemed necessary for the subject device. Bench testing included cleaning validation, analysis of bacterial endotoxin, organic/inorganic contaminants, and cytotoxicity.

Technological Characteristics

Material: Tivanium Ti-6Al-4V alloy. Design: Modular segmental system with male/female tapers and suture holes. Energy source: N/A (mechanical implant). Connectivity: N/A. Sterilization: Identical to predicate. Software: None.

Indications for Use

Indicated for patients with moderate to severe knee instability, significant bone loss/ligament deficiencies (neoplasms, trauma, arthritis, collagen disorders, avascular necrosis), valgus/varus/flexion deformities, or salvage of failed surgical attempts.

Regulatory Classification

Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

Dear Jason Heckaman:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for
