Features include dual-pitched threads and a threaded head for countersinking into bone. Available in 3.0 mm, 4.3 mm, and 6.5 mm diameters. Used by orthopedic surgeons in clinical settings for bone fragment stabilization, osteotomies, and arthrodesis. The device provides mechanical compression across fracture sites or fusion surfaces to facilitate bone healing. Selection of screw size is determined by the surgeon based on the specific anatomical site and clinical indication. ## Clinical Evidence No clinical data. Substantial equivalence is based on bench testing and comparison of physical/technological characteristics to predicate devices. ## Technological Characteristics Material: Titanium alloy (Ti-6Al-4V). Design: Cannulated, self-drilling, self-tapping, dual-pitched screw with threaded head. Diameters: 3.0 mm, 4.3 mm, 6.5 mm. Mechanical fixation principle. ## Regulatory 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. ## Predicate Devices - NewDeal Stabilization Screw ([K050346](/device/K050346.md)) - Vilex/Duval/Orthex Cannulated Bone Screw ([K991151](/device/K991151.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The screws are provided in the diameters 3.0 mm, 4.3 mm and 6.5 mm in various lengths and are available in Titanium alloy (Ti-6Al-4V). ### Intended use: Merete Compression Screws are indicated for fracture fixation and reconstruction of various bones, including - osteotomies in the foot (as Hallux Valgus treatment) or hand. - arthrodesis in hand, foot or ankle surgery, - - fixation of bone fragments in long bones or small bone fractures. - The size of the chosen screw should be adapted to the specific indication. ## Predicate Device: Screws 3.0 mm and 4.3 mm: K050346 NewDeal Stabilization Screw Screw 6.5 mm: K991151 Vilex/Duval/Orthex Cannulated Bone Screw ## Substancial Equivalence: Merete Compression Screws are similar to legally marketed predicate device listed above in that they share similar indications for use, are manufactured from similar materials and incorporate similar technological characteristics. Merete Medical GmbH {1}------------------------------------------------ ## 2 Bending Strength Rationale The referenced predicate devices in K050346 and K991151 are similar in their dimensions to the Merete Compression Screws 3.0, 4.3 and 6.5 mm as they present a similar core diameter, thread diameter as well as a similar cannulation. As the predicate devices are manufactured from similar materials (Ti-6Al-4V) too, the bending strength of the Merete Compression Screws 3.0, 4.3 and 6.5 mm can be supposed as similar as well. {2}------------------------------------------------ Image /page/2/Picture/0 description: The image shows the logo for the U.S. Department of Health & Human Services.
