• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Biomet Headless Compression Screws and Twist-Off Screws are indicated for fixation of bone fractures, fusion of a joint (arthrodesis) or bone reconstruction (osteotomy) of the mid-foot bones, metatarsal and phalanges of the foot or the phalanges, metacarpals and carpals of the hand. In the foot, these include procedures to correct Hallux Valgus (bunions), Hallux Varus and Hallux Rigidus, Hammer toe, Claw toe and Mallet toe.

Device Story

Bone fixation system comprising headless compression screws and twist-off screws of varying lengths/diameters; used for alignment and stabilization of skeletal fractures, arthrodesis, and osteotomies. Headless compression screws are cannulated, inserted below bone surface, and utilize dual-thread design for compression and reduced soft tissue irritation. Twist-off screws are solid, one-piece, and feature a thread-free segment for automatic compression; designed to break off cleanly upon contact with drill/pin driver. Used in clinical settings by surgeons. Submission introduces two new drivers with modified tip-taper length and radius of curvature to improve surgical utility. Output is physical fixation of bone segments; benefits include stable bone alignment and healing support.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by non-clinical bench testing, including torque testing and simulated use/breakage testing of the new drivers compared to the predicate.

Technological Characteristics

Metallic bone fixation fasteners. Cannulated headless screws and solid twist-off screws. Materials identical to predicate K142658. Mechanical fixation principle. Includes specialized drivers with modified tip-taper and radius of curvature. Sterilization method identical to predicate.

Indications for Use

Indicated for fixation of bone fractures, joint fusion (arthrodesis), or bone reconstruction (osteotomy) in mid-foot, metatarsal, and phalangeal bones of the foot, or phalanges, metacarpals, and carpals of the hand. Includes correction of Hallux Valgus, Hallux Varus, Hallux Rigidus, Hammer toe, Claw toe, and Mallet toe.

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 Andrew Steward:

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 mav, 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 avare 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

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

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 devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

| Predicate Device(s): | K142658 Headless Compression and Twist-Off Screws Biomet Inc. |
| Purpose and Device Description: | The Biomet Headless Compression and Twist-Off Screws consist of bone screws of various lengths and diameters and dimensionally optimized corresponding instruments which are used to aid in the alignment and stabilization of fractures to the skeletal system. The Biomet Headless Compression Screws are a cannulated headless screw, which is inserted below the bone surface. The Biomet Headless Compression Screw helps minimize soft tissue irritation and provides compression due to a dual thread design. The Biomet Twist-Off Screw is a solid one piece screw that has a direct connection to a drill or large diameter pin driver; this allows the screw to breakoff cleanly upon contact. The Biomet Twist-Off Screw also has compression capabilities with a thread-free segment that achieves automatic compression at the osteotomy site. |
