Intended Use

The Osteo Compression Hip Screw System is a proximal fracture fixation system, comprised of compression hip screw plates, lag screws, and a compression screw, which is intended to provide internal fixation with minimal soft tissue irritation. It is a system which optimally engages the femoral head and permits impaction of bone fracture fragments. Osteo Cortical Bone Screws may be utilized with this system for additional compression and fixation. This system is utilized as an aid to healing, not as a substitute for normal intact tissues. The Osteo Compression Hip Screw System is indicated for the following proximal fractures of the femur: - Intracapsular fractures of the femoral neck. - Intertrochanteric fractures of the femur.

Device Story

Proximal fracture fixation system; includes compression hip screw plates, lag screws, and compression screws. Used for internal fixation of femoral fractures; engages femoral head; permits impaction of fracture fragments. Plates feature barrel angles (130°, 135°, 150°) and varying lengths/screw holes to accommodate clinical needs. Lag screws are self-tapping. System provides stable fixation; aids healing. Used by surgeons in clinical/OR settings. Output is mechanical stabilization of bone fragments.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Materials: ASTM F-138 Stainless Steel (Grade 2, 316LVM). Components: Compression hip screw plates (130°, 135°, 150° angles), lag screws (self-tapping), and cortical bone screws. Mechanical fixation system. Non-sterile and sterile options.

Indications for Use

Indicated for patients with proximal femoral fractures, specifically intracapsular femoral neck fractures and intertrochanteric femoral fractures.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

130° Compression Hip Screw Plates: The Osteo 130° Compression Hip Screw Plates are available in three lengths (75mm, 91mm, and 107mm) with 4, 5, and 6 screw holes, respectively, for varied clinical situations. All plates have a 38mm barrel length and feature a 130° barrel angle. The barrel slides over the inserted lag screw; a compression screw may be used for additional compression of the fracture area. These plates have round holes which accommodate Osteo Cortical Bone Screws with a 4.5mm diameter.

Short Barrel Compression Hip Screw Plates: The Osteo Short Barrel Compression Hip Screw Plates are available in lengths of 75mm and 107mm, with either 4 or 6 screw holes, and two barrel angles (135° and 150°) for varied clinical situations. All plates have a 25mm barrel length.

#### Osteo Super Lag Screw:

The Osteo Super Lag Screw is available in lengths from 50mm to 145mm. All Osteo Super Lag Screws feature a 22mm thread length,14mm thread diameter, and self tapping thread. These lag screws are fabricated from ASTM F-138 Stainless Steel (Grade 2, 316LVM), and are offered both non-sterile and sterile.

### Intended Use

The Osteo Compression Hip Screw System is indicated for the following fractures of the femur: Intertrochanteric femoral fractures and intracapsular femoral neck fractures.

### Statement of Technological Comparison

The subject Osteo Compression Hip Screw System components (130° and Short Barrel Compression Hip Screw Plates, and Super Lag Screw) are substantially equivalent in design, materials, and intended use to the predicate devices offered by Howmedica in their Omega Plus Compression Hip Screw System.
