(DOUBLE SLIDING SCREWS) SYSTEM FOR OSTEOSYNTHSIS OF UNSTABLE FEMORAL NECK FRACTURES (K970258) _Ferguson Medical · HRS · May 22, 1997 · Orthopedic · SESE_ **Canonical URL:** https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/HRS/K970258 ## Device Facts - **Applicant:** Ferguson Medical - **Product Code:** [HRS](/submissions/OR/subpart-d%E2%80%94prosthetic-devices/HRS.md) - **Decision Date:** May 22, 1997 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 888.3030 - **Device Class:** Class 2 - **Review Panel:** Orthopedic - **Attributes:** Therapeutic ## Intended Use The D.S.S. System For Osteosynthesis of Unstable Femoral Neck Fractures is intended for use in the fixation and osteosynthesis of unstable femoral neck fractures. ## Device Story The Fixano D.S.S. (Double Sliding Screws) System is an implantable orthopedic device used for the osteosynthesis of unstable femoral neck fractures. The system functions as a hip screw mechanism designed to facilitate natural, weight-bearing compression at the fracture site. It consists of double sliding screws that can be utilized independently or in combination with a mini-plate to provide flexible fixation configurations. The device is intended for use by surgeons in orthopedic trauma procedures. By providing stable fixation and allowing controlled compression, the system aims to support bone healing and restore structural integrity in patients with unstable femoral neck fractures. ## Clinical Evidence No clinical data provided; substantial equivalence is based on technological characteristics and intended use. ## Technological Characteristics Hip screw mechanism for weight-bearing compression; consists of double sliding screws and optional mini-plate; implantable orthopedic hardware. ## 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 - Fixano D.S.S.

Classification name: Screw, fixation, bone, or appliance, fixation, nail/plate/blade combination, multiple component. Common/Usual name: Hip screw, hip pin, hip screw and plate, etc. Proprietary name: Fixano D.S.S. (Double Sliding Screws) System For Osteosynthesis of Unstable Femoral Neck Fractures. B. Substantial equivalence: Fixano D.S.S. (Double Sliding Screws) System (K954757), Synthes Dynamic Hip Screw (DHS) (K791619), Howmedica Omega Plus Compression Hip Screw System (K955306), and others. C. Device description: The Fixano D.S.S. (Double Sliding Screws) System For Osteosynthesis of Unstable Femoral Neck Fractures is an implantable device to be used in orthopedic trauma procedures. 3407 Bay Avenue • Chico, California 95973 • USA {1} K 470258 D. Intended use: The D.S.S. System For Osteosynthesis of Unstable Femoral Neck Fractures is intended for use in the fixation and osteosynthesis of unstable femoral neck fractures. E. Technological characteristics: The D.S.S. System For Osteosynthesis of Unstable Femoral Neck Fractures is a hip screw mechanism that allows a natural, weight-bearing compression. The D.S.S. screws can be utilized alone, or in combination with a mini-plate, allowing flexibility of osteosynthesis in most configurations of unstable femoral neck fractures.
