The Cannulated Headless Compression Screw (CHCS) is a sophisticated orthopedic implant specifically designed for stable fixation of bone fractures, such as scaphoid fractures. It allows for precise compression across the fracture site and is engineered to be countersunk below the articular surface to minimize interference with surrounding anatomy.
Make a 1-3 cm incision near the fracture site, avoiding major nerves and vessels. Gently separate soft tissues to expose the bone.
Restore the fracture to its anatomical position through manual traction and monitor accurately using C-arm fluoroscopy.
Insert a guide wire along the designed path under fluoroscopic guidance, perpendicular to the fracture plane.
Measure the required screw length using a dedicated measuring device over the guide wire to ensure a perfect fit.
Drill a hole using a cannulated drill bit with irrigation cooling. Insert the headless screw over the guide wire until the head is flush with the bone surface.
Irrigate the wound, perform layered suturing, and apply appropriate dressing or splinting.
