The indications for use of the K3 Bone Screw System™ are fixation/stabilization of small bones in hand or small bones in mid and forefoot fractures. ## Device Story K3 Bone Screw System consists of titanium alloy (Ti-6Al-4V ELI) bone screws used for fracture fixation and stabilization. Available in 3.5 mm diameter (cannulated and solid) with various lengths. Implanted by orthopedic surgeons using standard manual hexhead screwdrivers and general orthopedic instrumentation. Device provides mechanical fixation to stabilize bone fragments during healing. Clinical benefit derived from established orthopedic principles for bone fracture management, supported by over 75 years of clinical history for similar screw designs. ## Clinical Evidence No clinical data provided. Substantial equivalence is based on the long-term clinical history (75+ years) of bone screw designs, established manufacturing methods, and adherence to voluntary ASTM material and design standards. ## Technological Characteristics Material: Ti-6Al-4V ELI titanium alloy (ASTM F136-84). Instrumentation: Stainless steel (ASTM F899-84). Design: Threaded bone fixation fastener, 3.5 mm diameter, cannulated and solid configurations. Sterilization: Supplied non-sterile; requires user sterilization. No electronic or software components. ## 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 - Ace Medical Company ([K903810](/device/K903810.md)) - Alphatec Medical ([K921622](/device/K921622.md)) - Howmedica ([K931524](/device/K931524.md)) - Aesculap ([K940207](/device/K940207.md)) - Osteomed ([K924018](/device/K924018.md)) - Zimmer ([K792022](/device/K792022.md)) - A.O.

The product code generally refereed to is HWC (Product Code: HWC), and KMI submits this application under this designation. 3950 SORRENTO VALLEY BLVD., SAN DIEGO, CALIFORNIA 92121 TELEPHONE: (619)558-2233 FACSIMILE: (619)558-0838 {1} KINETIKOS MEDICAL KMI INCORPORATED Confidential FDA Notification of: Summary of Safety and Effectiveness Information Product: K3 Bone Screw System™ ## Performance Standards: No performance standards applicable to the Bone Screw have been established by the FDA. However, the titanium alloy 6AL-4V ELI alloy used to manufacture the KMI screws meets the chemical and mechanical requirements in voluntary standards established by the American Society for Testing and Materials (ASTM F136-84). ## Package and Labeling: Package labeling has been developed to industry standards. Packaging is also standard commercially available type quality and is stored in a fashion which prevents damage to the container or package the device is in. ## System Description: The KMI K3 Bone Screw System™ will be offered in Ti-6Al-4V ELI. It will be available in common styles and assorted lengths for bone fracture fixation and stabilization. Initially, a range of fifthteen screw lengths will be made available in 3.5 mm diameter (12-50 mm), and eight screw lengths will be made available in the 3.5 mm solid (12-26 mm) diameter screw. Both screw types are implantable using a standard (e.g. American Orthopedic) hexhead screwdriver, which is cannulated at center. ## Indications for Use: The KMI K3 Bone Screw System™ will be used on indications that are common with presently marketed devices. The indications for use of the K3 Bone Screw System™ are fixation/stabilization of small bones in hand or small bones in mid and forefoot fractures. 3950 SORRENTO VALLEY BLVD., SAN DIEGO, CALIFORNIA 92121 TELEPHONE: (619)558-2233 FACSIMILE: (619)558-0838 {2} KINETIKOS MEDICAL KMI UNCORPORATED Confidential FDA Notification of: Summary of Safety and Effectiveness Information Product: K3 Bone Screw System™ 3950 SORRENTO VALLEY BLVD., SAN DIEGO, CALIFORNIA 92121 TELEPHONE: (619)558-2233 FACSIMILE: (619)558-0838 # Substantial Equivalent Devices: This product is substantially equivalent in design, composition and function to other orthopedic screws manufactured and approved for market.
