Intended Use

The Hip Tool™ Implant is intended to stabilize a bone graft within the femoral head and neck to assist healing of an intraosseous fracture.

Device Story

Hip Tool™ Implant is a metallic bone fixation device used to stabilize bone grafts within the femoral head and neck to facilitate healing of intraosseous fractures. The system comprises a bone plate, barrel, graft compression screw, and locking screw. It is used in conjunction with manual surgical instruments for core decompression of osteonecrotic bone. The plate attaches to the femur via standard 4.5 mm cortical bone screws. The locking mechanism provides fixed-angle stability to bone fragments, similar to existing bone plate systems. The device is intended for use by surgeons in an operating room setting. By stabilizing the graft and fracture site, the device promotes bone healing and structural integrity of the femoral head.

Clinical Evidence

No clinical data provided; bench testing only. The device relies on established material biocompatibility (ASTM F138) and design equivalence to legally marketed predicate devices.

Technological Characteristics

Constructed from 316L medical grade stainless steel (ASTM F138, UNS S31673). Mechanical fixation device consisting of a bone plate, barrel, and screws. Features a locking mechanism for fixed-angle stability. Sterilized via radiation (ANSI/AAMI/ISO 11137).

Indications for Use

Indicated for patients requiring stabilization of bone grafts within the femoral head and neck to assist in the healing of intraosseous fractures.

Regulatory Classification

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.

The device is reviewed by the Orthopaedic and Rehabilitation Devices Panel and the Product Code for the device is HRS. # CONFORMANCE WITH PERFORMANCE STANDARDS No performance standards have been established under Section 514. Voluntary standards with which the Hip Tool™ Implant complies include American Society for Testing and Materials (ASTM) designation F138, Standard Specification for Wrought 18 Chromium-14 Nickel-2, 5 Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673) and ANSI/AAMI/ISO 11137, Sterilization of Health Care Products - Radiation Sterilization. {1}------------------------------------------------ KO221349 ### INTENDED USE The Hip Tool™ Implant is intended to stabilize a bone graft within the femoral head and neck to assist healing of an intraosseous fracture. ## DEVICE DESCRIPTION ### Design Characteristics The Hip Tool™ Implant is a component of the Hip Tool™ Bone Graft Stabilization System (BGSS). The complete system consists of the Hip Tool™ Implant, and a series of manual surgical instruments (Class 1, exempt, not a subject of this submission) intended to assist in core decompression of osteonecrotic bone in the femoral head. The Hip Tool™ Implant consists of a bone plate and barrel and a graft compression screw and locking screw. The plate is attached to the femur using standard 4.5 mm cortical bone screws. The Hip Tool™ Implant is intended to stabilize a bone graft that is placed during the surgical procedure. ## Material Composition The Hip Tool™ Implant is made from 316L medical grade stainless steel that meets ASTM designation F138, Standard Specification for Wrought 18 Nickel-2.5 Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673). The use of Type 316L stainless steel is widespread in commercially distributed, permanently implanted medical devices and the material is widely considered to be biocompatible. # EQUIVALENCE TO MARKETED PRODUCT Orthopedic Sciences, Inc. submits the following information to demonstrate that, for the purposes of FDA's regulation of medical devices, the Hip Tool™ Implant is substantially equivalent in indications and design principles to the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices, and to a surgical procedure that is a currently accepted protocol. The design and functional characteristics of the Hip Tool™ Implant and the predicate procedures and devices are substantially the same. They function by stabilizing a fracture to promote healing of cancellous bone. The closest predicate is a surgical procedure detailed by Urbaniak and Harvey (J Am Acad Orthop Surg 1998; 6:44-54) which is a currently accepted protocol. Both the use of the Hip Tool™ BGSS and this procedure utilize core decompression and cancellous bone grafting to stabilize the resultant intraosseous fracture. Other predicate bone plate based devices are the Synthes Distal Femur Plate (DFP) System (K982222), Synthes Locking Condylar Plate (LCP) System (K000066), BioPro Wujin #3 femoral bone plate (K011459), DuPuy ACE Medical Trochanteric Side Plate (K970503), Stryker Plating System Basic Fragment Set (K012162), Metagen High Tibial Osteotomy System (K963700), Smith {2}------------------------------------------------ 510(k) Summary ## Hip Tool™ Implant Page 3 عَلَّ مَ مَثُ & Nephew Bone Plate System (K993106), Syntec-Taichung Medical Instruments Non-sterile Titanium Alloy Mini Plate (K983988) and Ferguson Medical Orthopedic Plate System (K972219). All of these marketed devices provide stabilization of bone fragments to promote healing of bone. In particular, the Synthes Distal Femur Plate includes a threaded hole whereby the head of the bone screw can be locked to the plate to create a fixed angle. This locking mechanism provides additional stability to the bony fragments when the screw is engaged in the bone. The Hip Tool similarly has a locking mechanism that is intended to stabilize bone fragments. Predicate devices used to stabilize fractures of the femoral neck are the Osteonics Osteo Compression Hip Screw System (K982553), and the Ferguson Medical Fixano D.S.S. System for Osteosynthesis of Unstable Femoral Neck Fractures (K970258). These devices provide stabilization of femoral neck fractures to promote healing of bone. Other devices with similar intended use include the MacroPoreOS Protective Sheet (K994158), Synthes Resorbable Meshes and Sheets (K003788) and Biomet LactoSorb Panels and Fasteners (K011139 and K984390). These devices maintain position of weak bony tissue, bony fragments, bone grafts and bone graft substitutes, and morselized bone graft to promote healing of bone. {3}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
