• Device Name: MODIFICATION TO BILOK SCREW
• Applicant: Biocomposites, Ltd.
• Product Code: HWC · Orthopedic
• Decision Date: May 17, 2007
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Bilok® Screw is indicated for use in anterior cruciate ligament (ACL) reconstruction procedures where the surgeon places the graft in tibial and/or femoral tunnels and inserts screws between the tunnel wall and graft to hold the graft in place. The Bilok® Screw is used to provide interference fixation of patellar bone-tendon-bone grafts in ACL reconstruction. The Bilok® Screw is used to provide interference fixation during femoral and/or tibial fixation in ACL reconstruction using a soft tissue graft (semi-tendonosis gracilis).

Device Story

Cannulated, sterile, single-use bone screw; composed of calcium phosphate and poly L-lactic acid (PLLA) composite. Used by surgeons in ACL reconstruction procedures to provide interference fixation of grafts within tibial or femoral tunnels. Device inserted between tunnel wall and graft to secure graft in place. Benefits include mechanical stabilization of graft during healing.

Clinical Evidence

No clinical data provided; substantial equivalence based on non-clinical testing and technological comparison.

Technological Characteristics

Cannulated bone screw; composite material of calcium phosphate and poly L-lactic acid (PLLA); sterile; single-use.

Indications for Use

Indicated for patients undergoing anterior cruciate ligament (ACL) reconstruction requiring interference fixation of patellar bone-tendon-bone grafts or soft tissue (semi-tendonosis gracilis) grafts in tibial and/or femoral tunnels.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Mr. Fitzer:

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. Iisting 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 (PMA), 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 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); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
