What is a Cannulated Headless Compression Screw?
The Headless Compression Screw is a specialized cannulated screw used primarily for scaphoid fracture fixation and other small bone procedures. This innovative design generates significant compression across the fracture site before being countersunk completely below the articular surface, minimizing hardware prominence and soft tissue irritation.
Make a small incision (1-3 cm) near the fracture site, avoiding vital nerves and vessels. Gently separate muscles and fascia to fully expose the fracture end.
Restore normal anatomical position through manual traction and rotation. Monitor the reduction accuracy continuously using C-arm fluoroscopy.
Insert the guide wire under fluoroscopic guidance along the designed path, ensuring it is perpendicular to the fracture plane.
Use a dedicated measuring device over the guide wire. Select a screw approximately 2-4 mm shorter than the measured depth to ensure proper burial.
Use a cannulated drill bit matching the screw size. Use irrigation to cool the bit and prevent thermal injury to the bone.
Mount the screw onto the compression sleeve and advance manually over the wire. Once the sleeve contacts the bone, further rotation closes the fracture. Use a screwdriver to advance the head until flush with the bone.
Irrigate the wound with saline, suture in layers, and apply appropriate dressing or splinting.
