Circular Fixation System | | Common Name: | Multilateral Fixators and Accessories | | Device Classification Name and<br>Reference: | 21 CFR 888.3030, Single/multiple component metallic bone<br>fixation appliances and accessories. | | Device Class: | Class II | | Panel Code: | Orthopaedics/87 | | Product Code: | KTT, OSN | ### Device Description Subject of this Traditional 510(k) premarket notification is the Smith & Nephew Circular Fixation System. The subject device is a multilateral external fixation system that is intended for fracture fixation of long bones and for joint fusions and limb lengthening or deformity corrections which involve cutting of the bone. The Circular Fixation system can also be used with a software component that is designed to be used to assist the physician in adjusting the six struts by creating a patient adjustment schedule. Components of this premarket notification include the following: - Full, half, 2/3 and foot rings manufactured from aluminum material. . - . U-plates manufactured from aluminum material. - Adjustable struts manufactured from aluminum material . - . Drill tip wires manufactured from stainless steel material - Accessory components such as rancho cubes, ring connectors, nuts, bolts and centering . sleeves manufactured from stainless steel material - . Disc clips manufactured from polycarbonate material - Half pin caps manufactured from PVC material � - . Web-based software The Circular Fixation System can also be used with other existing Smith and Nephew, Inc external fixation components. #### Technological Characteristics A review of the mechanical data indicates that the hardware components of the Circular Fixation System are capable of withstanding expected in vivo loading without failure. In addition, software verification and validation testing was completed in line with FDA's guidance document entitled, "General Principles of Software Validation; Final Guidance for Industry and FDA Staff," dated January 11, 2002. The results of the testing indicate that the software will perform as intended. The following mechanical and software testing of the Circular Fixation System was performed: {1}------------------------------------------------ - . Cutting Performance Evaluation of Drill Tip Wires - Evaluation of the maximum Tightening Torque of the Pin Connector Hinge and the Pin . Connector Post - . Mechanical Evaluation of the Pin Connector Assembly - . Evaluation of the Wire Pull-Out Force and Maximum Threading Torque of the Combo Wire Fixation Bolt - . Mechanical Evaluation of the ControlFx Strut - Software Installation Qualification Protocol ● - Software Operational Qualification Protocol . - . Software Performance Qualification Protocol A review of this testing has demonstrated that there are no new issues related to the safety and effectiveness of the subject devices. Clinical data was not needed to support the safety and effectiveness of the subject devices. #### Intended Use The Smith & Nephew Circular Fixation System is intended to be used for post-traumatic joint contracture which has resulted in loss of range of motion; fractures and disease which generally may result in joint contractures or loss of range of motion and fractures requiring distraction; open and closed fracture fixation; pseudoarthrosis of long bones; limb lengthening by epiphyseal or metaphyseal distraction; correction of bony or soft tissue deformities; correction of bony or soft tissue defects; joint arthrodesis; infected fractures or nonunions. Components in the Smith & Nephew Circular Fixation System are for single use only. #### Substantial Equivalence Information The substantial equivalence of the Circular Fixation System is based on its similarities in indications for use, design features, operational principles, and materials to the following predicate systems: | Manufacturer | Description | Submission<br>Number | Clearance Date | |----------------|---------------------------------------------------|----------------------|----------------| | Smith & Nephew | Illizarov (Richards) External Fixation<br>System | K870961 | 03-19-1987 | | Smith & Nephew | Illizarov External Fixation System | K962808 | 08-19-1996 | | Smith & Nephew | Taylor Spatial Frame | K970748 | 05-09-1997 | | Smith & Nephew | External Fixation System | K994143 | 02-18-2000 | | Smith & Nephew | Jet-X Bar System Clamps, Bar and<br>Posts | K072212 | 03-07-2008 | | Smith & Nephew | VLP Foot Plating, Screw system and<br>Accessories | K090675 | 06-04-2009 | #### Conclusion As previously noted, this Traditional Premarket Notification is being submitted to request clearance for the Circular Fixation system. Based on the similarities to the predicate components and a review of the mechanical and software testing performed, the devices are substantially equivalent to above predicate external fixation systems. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a circular seal or logo.
