Intended Use

The Fixion Dynamic Hip Screw System (Fixion DHS) is intended for use in fixation of fractures in the proximal femur. The Fixion DHS is indicated for use in pertrochanteric, intertrochanteric, and base of femur neck fractures. The Fixion DHS can be implanted in an open or in a minimally invasive approach.

Device Story

Fixion DHS is a metallic orthopedic fixation system for proximal femur fractures. Components include a titanium plate, a hip peg with a distal expandable section, a locking pin, and screws. The hip peg is expanded in situ using a manual inflation device (pump) to enhance abutment within the femoral head. The system is implanted via open or minimally invasive surgery by orthopedic surgeons. The device provides mechanical stabilization of bone fragments. The expandable peg mechanism is designed to improve fixation in the femoral head, potentially benefiting patients by providing secure fracture reduction and stabilization.

Clinical Evidence

Bench testing only. The device underwent mechanical testing per ASTM F 382-99 and ASTM F 384-00, and testing for non-articulating, mechanically locked modular implant components per FDA guidance.

Technological Characteristics

Materials: Titanium and Titanium alloy (ASTM F 1472-02, ASTM F 136-02, ASTM F 67-00); surgical grade Stainless Steel (ASTM F 899-02, ASTM F 1586-95); Silicone and Celeron (ISO 16061). Principle: Mechanical fixation via plate, screws, and an expandable hip peg. Energy source: Manual (manual pump for peg expansion). Form factor: Modular plate and screw system. Connectivity: None.

Indications for Use

Indicated for patients with pertrochanteric, intertrochanteric, and base of femur neck fractures requiring proximal femur fixation.

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.

#### System Description

The Fixion DHS System consists of the following components:

- Plate a solid, titanium-made, component, incorporating holes for the insertion of A the Hip Peg, Locking Pin and Screws. The Plate Body is shaped to comply with the hone curvature and the Barrel is located at 135° - 145° relative to the Plate Body.
- Hip Peg a titanium-made tube with a distal expandable section, to enhance the A abutment of the Hip Peg inside the femoral head. The expandable body ends with a conical shaped distal end.
- Locking Pin a titanium-made pin. It is used to provide additional fixation of the A fragment, if needed, and for stabilizing bone fragments in case of torsional instability
- Screws titanium screws. Maximum of 3 7 Screws (Plate length dependant) can A be used to attach the plate to the bone (the femur shaft) at its distal section.
- Instrumentation Set ~ a set of accessories to be used with the Fixion DHS implants. A Accessories for both open and minimally invasive surgical approaches are available.
- A Inflation Device (Pump) - a manual pump used to expand the Hip Peg.

#### Substantial Equivalence

The Fixion DHS intended use, design, matcrials, technological characteristics and principles of operation are substantially equivalent to those of Disc-O-Tech's Fixion Interlocking PF Intramedullary Nailing System (K010988, K012967, K023437) and Fixion Interlocking Intramedullary Nailing System (K002783, K013449, K023437), Gotfied PC.C.P (K983814), Biomet VHS (K964880) and DePuy ACE TK2 Compression Hip Screw System (K972629).
