Device Story

Bone fixation system comprising Snap Off Screws, Double Thread Compression Screws, Guide Wires, and Staples. Used in orthopedic surgery (foot/hand/ankle) by physicians. Screws and staples provide mechanical fixation of bone fragments or reconstruction; guide wires assist in implant positioning. Snap Off technology allows distal end of staple to serve as drilling gauge/grip, then snapped off after placement. Manual insertion for screws; machine insertion for guide wires. Devices provide stable fixation to facilitate bone healing.

Clinical Evidence

Bench testing only. Testing included torque tests, break-off tests, sideways stability tests, maximum torque tests, screw-in tests, screw compression tests, and ASTM F564-10 testing for staples.

Technological Characteristics

Materials: ASTM F136 (Ti-6Al-4V ELI) for screws/staples; ASTM F138 (1.4441) for guide wires. Dimensions: Screws (10-36mm length, 2-4mm diameter); Guide wires (80-380mm length, 0.7-6.35mm diameter); Staples (8-25mm size). Features: Cannulated screws, SnapOff technology for staples, trocar end styles for wires. Manual or machine insertion.

Indications for Use

Indicated for patients requiring bone fracture fixation, bone reconstruction, or soft tissue/tendon fixation in the foot, hand, or ankle. Includes use for arthrodesis, osteotomies, and small bone fragment stabilization. No specific age or gender contraindications stated.

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.

#### 4. Description of the Device

#### Z-Snap Off Screw 4.1.

Main application of the Snap Off Screw is the forefoot surgery. The device is intended to connect bones or bone fragments. Especially in the classic "Well"-osteotomy you can fix the two parts of bones with this kind of screw.

Material: ASTM F136 (Ti-6AI-4V ELI) Length: 11 mm to 14 mm Diameter: 2 mm

#### 4.2. Z-Double Thread Compression Screw

The Double thread compression screw is mainly used in the forefoot surgery. Most common use is in the "Scart"-osteotomy. They are cannulated to work with a guide wire and they are drilled in manually.

Material: ASTM F136 (Ti-6Al-4V ELI) Length: 10 mm to 36 mm Diameter: 3 and 4 mm

#### 4.3. Z-Guide Wire

Guide wires are used in all fields of surgery. Main applications are: determine the correct position for e.g. screws or drills, or fixation of bones, fragments. They are usually put in by machine. Guide wires are also used to drill holes, e.g. to apply staples.

| Material: | ASTM F 138 (1.4441) |
|-------------|---------------------|
| Length: | 80 mm to 380 mm |
| Diameter: | 0.7 mm to 6.35 mm |
| End Styles: | Trocar |
| Type: | Smooth |

#### Z-Staple 4.4.

Staples are implants for fixing bones or fragments. Z-Staples use the SnapOff-technology by Z-Medical. The distal end of the staple can be uses as drilling gauge as well as grip to put in the staple. After reaching the final position, the grip can be snapped off by moving sideways.
