Indications for Use

The Herbert ™ Mini Bone Screw (2.5mm diameter, non- cannulated) and the Herbert ™ Bone Screw (3.0mm diameter, non-cannulated) are indicated for fixation of intra-articular and extra-articular fractures, avulsions, non- union, and osteotomies of small bones and small bone fragments; as well as arthrodeses of small joints. The Herbert/Whipple ® Bone Screw System (3.0mm diameter, cannulated) are indicated for the fixation of fractures and non-unions of small bones and small bone arthrodeses, including, but not limited to, scaphoid fractures; intra-articular fractures of the tarsals, metatarsals, carpals and metacarpals; bunionectomies and osteotomies; arthrodeses of small joints (e.g. phalanges); fractures of the patella, ulna and radial styloid. The Herbert ™ Cannulated Bone Screw System (4.5mm and 6.5mm diameter) are indicated for fracture fixation, reconstruction, osteotomy, and arthrodesis of various bones and bone fragments including joint fusions (arthrodeses) in the foot and fixation of intra-articular fractures of the humerus, femur and tibia.

Device Story

Herbert/Whipple Bone Screw System consists of cannulated and non-cannulated variable pitch, headless screws; threaded at both ends. Fabricated from Tivanium (Ti-6Al-4V alloy). Designed for rigid fixation of bone fractures, non-unions, and arthrodeses. Used by surgeons in clinical settings. Screws provide compression across fracture sites or joints. Mechanical performance verified via axial pull-out force, torque-to-failure, and static bending moment testing. Benefit: stable fixation to promote bone healing.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical bench testing: shelf-life (10 years), biocompatibility (ISO 10993-1), and mechanical performance (axial pull-out, torque-to-failure, static bending moment).

Technological Characteristics

Materials: Tivanium (Ti-6Al-4V alloy). Design: Cannulated and non-cannulated variable pitch, headless screws, threaded at both ends. Biocompatibility: ISO 10993-1. Mechanical testing: Axial pull-out, torque-to-failure, static bending moment.

Indications for Use

Indicated for fixation of fractures, non-unions, avulsions, osteotomies, and arthrodeses of small bones/fragments (e.g., scaphoid, tarsals, metatarsals, carpals, metacarpals, phalanges, patella, ulna, radial styloid) and larger bones (humerus, femur, tibia).

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. McKelvey:

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, 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

{5}------------------------------------------------

were significantly less than the torque-to-failure for the screws, indicating that each of the subject screws can be inserted and removed during surgery without screw failure.

Conclusions: The data presented in this submission show that the changes do not affect the safety and/or effectiveness of the subject devices and that the subject devices will perform in a substantially equivalent manner to the predicate devices.

Clinical Performance and Conclusions:

Clinical data and conclusions were not needed for these devices to show substantial equivalence.
