Intended Use

The Little Grafter™ Screw is intended for fixation of fractures of small bones and small bone arthrodeses, including, but not limited to, scaphoid fractures; intra-articualar fractures of the tarsals, metatarsalsm carpals and metacarpals; bunionectomies and osteotomies; arthrodeses of small joints (e.g. phalanges); fractures of the patella, ulna and radial styloid.

Device Story

Little Grafter™ Screw is a cannulated, sterile, single-use bone fixation screw; composed of a mixture of calcium salt and bioabsorbable polymer. Used by surgeons for internal fixation of small bone fractures and arthrodeses. Device provides mechanical stability to fracture sites during healing; material properties allow for bioabsorption. Clinical benefit includes stabilization of bone segments to facilitate union. No complex electronics or software involved.

Clinical Evidence

Bench testing only. Results confirm the composite screw possesses sufficient strength for early and sustained fixation of fracture sites, with performance metrics comparing favorably to the predicate devices.

Technological Characteristics

Cannulated bone fixation screw; material: composite mixture of calcium salt and bioabsorbable polymer; sterile; single-use; mechanical fixation principle.

Indications for Use

Indicated for fixation of small bone fractures and arthrodeses, including scaphoid, tarsal, metatarsal, carpal, metacarpal, patella, ulna, and radial styloid fractures, as well as bunionectomies, osteotomies, and small joint arthrodeses.

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. Bratt:

We have reviewed your Section 510(k) premarket notification of intent to market the device refercnced 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, 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 (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.
