The system provides an alternative to sublaminar and intraspinous process wiring for trauma applications. Another application is the use of the MSD CABLE REDUCTION SYSTEM for instrumentation involved in the correction of scoliotic, kyphotic, and lordotic deformities. The system may also be used with other spinal implants such as the MSD Unit Rod, the ATLAS™ CABLE System or the Luque Rod, or wherever "wiring" may help secure the attachment of other implants. ## Device Story MSD Cable Reduction System is a temporary orthopedic implant system consisting of multi-stranded cables and ancillary components (screws, hooks). Used in thoracic and lumbar spine surgery to provide temporary stabilization, augment bony fusion, or repair bone fractures. Operates as a mechanical fixation device; functions as an alternative to traditional wiring techniques. Used by surgeons in clinical settings to secure spinal implants (e.g., MSD Unit Rod, Luque Rod). Provides structural support to aid in deformity correction and bone healing. Sold sterile or non-sterile. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Materials: Medical grade stainless steel (ASTM F-138, ISO 5832-1/9), titanium alloy (ASTM F-136, ISO 5832-3), or pure titanium (ASTM F-67, ISO 5832-2). Mechanical fixation system consisting of multi-stranded cables, screws, and hooks. Non-electronic, non-software device. ## Regulatory Identification A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome. ## Predicate Devices - ATLAS™ CABLE System ## Reference Devices - MSD Unit Rod - Luque Rod ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

I. Company: 1800 Pyramid Place Memphis, TN 38132 (901) 396-3133 #### Proposed Proprietary Trade Name: II. MSD CABLE REDUCTION SYSTEM Regulation Numbers: 888.3050 and 888.3010 Regulation Names: Bone Fixation Cerclage, Spinal Interlaminal Fixation Orthosis Codes: KWP, JDQ #### Description III. The MSD CABLE REDUCTION SYSTEM is a temporary implant for the use in orthopaedic surgery. The system is intended to help provide temporary stabilization, augment the development of solid bony fusion and/or aid in the repair of bone fractures. The system consists of a multi-stranded cable and ancillary components used in several different configurations. The MSD CABLE REDUCTION SYSTEM implant components are made of medical grade stainless steel described by ASTM Standard F-138 or ISO 5832-1 or ISO 5832-9. Alternatively, the system may be made out of titanium alloy or titanium, as described in ASTM F-136 or ISO 5832-3 for the surgical grade titanium alloy and ASTM F 67 or ISO 5832-2 for pure titanium. The MSD CABLE REDUCTION SYSTEM may be sold sterile or non-sterile. #### IV. Indications for Use: The MSD CABLE REDUCTION SYSTEM screws and hooks are only intended for use in the thoracic and lumbar spine. The system provides an alternative to sublaminar and intraspinous process wiring for trauma applications. Another application is the use of the MSD CABLE REDUCTION SYSTEM for instrumentation involved in the correction of scoliotic, kyphotic, and lordotic deformities. The system may also be used with other {1}------------------------------------------------ spinal implants such as the MSD Unit Rod, the ATLAS™ CABLE System or the Luque Rod, or wherever "wiring" may help secure the attachment of other implants. #### Substantial Equivalence: V. The subject MSD CABLE REDUCTION SYSTEM components were declared substantially equivalent to the predicate ATLAS™ CABLE System components manufactured by Medtronic Sofamor Danek. © 2003 Medtronic Sofamor Danek {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
