Headless Compression Hollow Screw Cannulated Screw Bone Screws Orthopedic Implants Bone Implant

Make a small incision (1-3 cm) near the fracture site while avoiding nerves and blood vessels. Gently separate soft tissues to fully expose the fracture end.

Restore the bone to its anatomical position using manual traction and rotation. Use C-arm fluoroscopy to ensure accurate alignment.

Determine the entry point and insert the guide wire under fluoroscopic guidance along the designed path until it reaches the appropriate position.

Use a dedicated measuring device over the guide wire. Alternatively, compare with a second guide wire of the same length to calculate the required depth.

Select a cannulated drill bit and drill along the guide wire. Use irrigation to cool the bit and minimize thermal injury to the bone.

Mount the headless screw onto the compression sleeve and insert manually. Advance the screw until the head is flush with the bone and threads are fully buried.
