Intended Use

In cemented hip arthroplasty, when the cement spacer, restrictor and/or plug is thought to be advantageous.

Device Story

Single-use cylindrical plug; manufactured from PMMA or PMMA with Barium Sulfate; used in cemented hip arthroplasty. Device features friction-fit design; inserted intraoperatively into distal hole of cemented hip stem to prevent cement intrusion into distal femoral canal. Operated by physician; provides mechanical occlusion of distal hole. Benefits patient by preventing cement migration; simplifies surgical workflow during hip stem implantation.

Clinical Evidence

No clinical data. Substantial equivalence based on material composition and mechanical function comparison to legally marketed predicate devices.

Technological Characteristics

Materials: Polymethylmethacrylate (PMMA) or PMMA mixed with Barium Sulfate (BaSO2). Form factor: Cylindrical, single universal size, rounded distal tip, friction-fit design. No centering fins. Non-powered, mechanical accessory.

Indications for Use

Indicated for patients undergoing cemented hip arthroplasty where use of a cement spacer, restrictor, or plug is deemed advantageous by the physician.

Regulatory Classification

Identification

Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.

#### Predicate Device Identification

The Osteonics® Distal Hole Plug employ features which are substantially equivalent to features of the following Howmedica Osteonics predicate devices, which has been cleared for marketing via the 510(k) process:

- Osteonics® Omnifit® Universal Distal Cement Spacer (K914406) .
- Osteonics® Universal Distal Spacer (K894708)

## Device Description

The Osteonics® Universal Distal Hole Plug is a single use component which is intended for optional use in cemented arthroplasties of the hip as determined by the physician. The Universal Distal Hole Plugs are manufactured from polymethylmethacrylate (PMMA) or PMMA mixed with Barium Sulfate (BaSO2) and are available in one universal size. The Universal Distal Hole

{1}------------------------------------------------

Plug is cylindrical in shape, has a rounded distal tip, and flares very slightly from the proximal to The Universal Distal Hole Plug also employs a friction-fit design which secures it in distal end. the distal hole of any commercially available Osteonics® cemented hip stem. The Universal Distal Hole Plug is assembled to the hip stem intraoperatively and inserted into the femoral canal.

# Intended Use:

The indications for the use of the Osteonics® Universal Distal Hole Plug, in keeping with those of other legally marketed Howmedica Osteonics accessory products for cemented arthroplasty, are as follows:

For cement spacers, mid-shaft restrictors, and Cement-Plugs:

- In cemented hip arthroplasty, when the cement spacer, restrictor and/or plug is thought to be advantageous.
## Statement of Technological Comparison:

The Osteonics® Universal Distal Hole Plug is substantially equivalent, in terms of material and basic mechanical function, to the legally marketed versions of the predicate Osteonics® Omnifit® Universal Distal Cement Spacer, manufactured from PMMA mixed with Barium Sulfate, and the predicate Osteonics® Universal Distal Spacer, manufactured from PMMA. The subject and predicate devices are all intended to address similar conditions. However, the predicate devices have fins used for centering the spacer in the femoral canal, whereas the subject device has no fins and serves only to occlude the distal hole of the cemented hip stem in order to prevent cement from intruding into the distal hole. The Universal Distal Hole Plug is available in one universal size because, unlike the predicate device, the subject device does not incorporate fins. Each of the subject and predicate devices is for optional use and is provided in order to accommodate physician preference.

We have reviewed your Section 510(k) notification of intent to market the device referenced above, and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General Regulation (21 CFR Part 820), and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions.
