Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, non-unions and malunions. This system can be used for palmar, dorsal or orthogonal application. ## Device Story Aiming blocks serve as surgical accessories for VariAx® Distal Radius Locked Plating System; used intra-operatively to guide screw placement into bone plates. Four block configurations correspond to volar plate types (Narrow Right/Left, Standard Right/Left). Surgeon uses joystick tool to determine screw trajectory; block pinned in place once alignment achieved. Kirschner wires may be used for trajectory verification. Device assists surgeon in achieving accurate screw orientation during fracture fixation; improves procedural efficiency and alignment precision. ## Clinical Evidence No clinical data. Bench testing only: torque-to-failure testing of joystick/block assembly and lateral load testing of the construct were performed to ensure structural integrity. ## Technological Characteristics Materials: PEEK and stainless steel. Components: Aiming blocks (4 configurations) and joystick tool. Function: Mechanical guidance for screw trajectory. Sterilization: Not specified. Connectivity: None (mechanical accessory). ## Regulatory Identification Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - VariAx® Distal Radius Locked Plating System ([K040022](/device/K040022.md)) - VariAx® Distal Radius Locked Plating System ([K100271](/device/K100271.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Sponsor: 325 Corporate Drive Mahwah, NJ 07430 Contact Person: Stephanie M. Fitts Sr. Director, Regulatory Affairs and Regulatory Compliance Howmedica Osteonics Corp. 325 Corporate Drive Mahwah, NJ 07430 Phone: (201) 831-5405 August 16, 2011 Date Prepared: Proprietary Name: VariAx® Distal Radius Locked Plating System Line Extension for addition of Aiming Blocks Common Name: Bone plates and Screws Classification Name: Single/multiple component metallic bone fixation appliances and accessories, 21 CFR §888.3030 Device Product Code:87 HRS: Plate, Fixation, Bone # Legally Marketed Device to Which Substantial Equivalence is Claimed: VariAx® Distal Radius Locked Plating System #### Device Description: This Special 510(k) submission is intended to add aiming blocks as an accessory to the VariAx® Distal Radius plate line which was cleared in K040022 and K100271. The aiming blocks are accessories used intra-operatively to guide the user in placement of the screws into the plate. There are 4 aiming blocks which correspond to the configurations of volar plates: Narrow Right, Narrow Left, Standard Right and Standard Left. The aiming blocks are used with a joystick tool which helps the user find the appropriate screw trajectory and is pinned in place once the desired alignment is obtained. Kirschner wires can also be used in conjunction with the aiming blocks to determine screw trajectory. # Intended Use: The VariAx® Distal Radius Locked Plating System Line Extension addition of Aiming Blocks does not alter the intended use of the predicate system as cleared in K040022 and K 100271. The indications for use for the subject plates are provided below. {1}------------------------------------------------ VariAx® Distal Radius Locked Plating System Line Extension Aiming Blocks Special 510(k) # Indications for Use: The VariAx® Distal Radius Plates are intended for use for internal fixation for fractures and reconstruction of the small bones, primarily including the distal radius. Examples of these internal fixations and reconstructions include compression fractures, intra-articular and extra-articular fractures, displaced fractures, osteotomies, non-unions and malunions. This system can be used for palmar, dorsal or orthogonal application. ### Summary of Technologies: The proposed device is substantially equivalent in intended use, materials and performance characteristics to the predicate device. Addition of the aiming block as an accessory to the bone plating system does not alter the technology. ## Non-Clinical Testing: Benchtop testing was conducted to demonstrate that the use of the aiming blocks as described in the operative technique could withstand clinically relevant loads. Torque to failure was performed using the joystick and the block assembled and failure loads were found to be acceptable. Lateral loads were also placed on the construct and the failure mode was disassembly without significant damage to the plate. Biocompatibility testing of the materials in the aiming block assembly (PEEK and stainless steel) was conducted as well as cleanability testing, sterility testing and corrosion resistance testing. ## Clinical Testing: Clinical testing was not required for this submission. #### Conclusion: The VariAx® Distal Radius Locked Plating System Line Extension addition of Aiming Blocks are substantially equivalent to the predicate devices identified in this premarket notification. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the Department of Health and Human Services (HHS).
