Intended Use

The ODi Ultimate Compression Screw System™ was designed for use on indications comparable to those for approved and marketed devices. The primary indications are for the stabilization of osteotomies in small bones, and the fixation of unstable or interfragmentary fractures. This device is not intended for use in the spine. The ODi Ultimate Compression Screw™ is indicated for: 1. Small Hand Bone Fractures 2. Carpal and Metacarpal Fractures 3. Tarsal and Metatarsal Fractures 4. Distal Metatarsal Osteotomies (Austin Chevron, Scarf) 5. Interfragmentary Radius and Ulna Fractures 6. Osteochondral Fractures 7. Intra-articular fractures 8. Arthrodesis of small joints 9. Reconstructive osteotomies in small carpal or tarsal bones 10. Osteochondritis Dissecans 11. Oblique fractures of the fibula 12. Metatarsal osteotomies and other reconstructive surgeries in the foot

Device Description

The ODi Ultimate Compression Screw™ will be offered in Ti-6Al-4V ELI. It will be available in common styles and assorted lengths for bone fracture fixation and stabilization. The Ultimate Compression Screw System™ consists of three screw components designed to be used as an assembly. The device has been designed to offer a wide range of compression, and screw sizes to address varving fracture and bone fragment geometries. The assembly consists of the following: - Proximal Screw Component . - Distal Screw Component . - Internal Compression Screw t The screw components are equivalent in design to currently marketed standard compression bone screws. The thread form and defining screw features conform to ISO 5835, Metal Bone Screws with Hexagonal Drive Connection, Spherical Under-Surface of Head, Asymmetrical Thread Dimensions. Initially, ten screw lengths will be available in 3.5 mm, 4.5 mm and 6.5 mm diameters, offering a range of fracture compression from 14.0 mm to 58.0 mm. The components are self-tapping and are designed to be manually inserted using commonly available (e.g. American Orthopedic) surgical instruments. All device components are manufactured from titanium alloy, Ti-6Al-4V, per ASTM F136 and provided in detail as follows: Proximal Screw Component The proximal screw component is provided in outer diameters of 3.5 mm, 4.5 mm and 6.5 mm. This allows for implantation into either cortical or cancellous bone. The surgeon selects the component diameter and length based upon the bone type and the size of the bone fragment requiring fixation. Distal Screw Component The distal screw component is provided in outer diameters of 3.5 mm, 4.5 mm, and 6.5 mm. This allows for implantation into either cortical or cancellous bone. The surgeon selects the component diameter and length based upon the bone type and the size of the bone fragment requiring fixation. Internal Compression Screw The 2.0 mm internal compression screw is designed to seat within the proximal component and thread into the distal component. As the internal compression screw is threaded into the distal screw component, it draws the proximal and distal screw components together, thereby achieving fracture fixation. Note that the internal compression screw is designed to universally fit all proximal and distal screw sizes. This gives the system a modularity that allows the surgeon to select the proximal and distal screw combination that best addresses the fracture geometry.
