[Use of the Herbert Screw with the Freehand Method for Osteosynthesis of Acute Scaphoid Fracture]

Scaphoid fracture is, in most cases, usually still treated conservatively. The disadvantages of long-term immobilization are stiffness of the wrist joint, loss of strength and higher costs. The osteosynthesis of the scaphoid fracture with the Herbert bone screw restores the exact form and length and the normal position of the scaphoid to the other carpal bones. It prevents non-unions, arthrosis and other late complications. The Freehand method is used as a percutaneous technique without utilization of a jig. The scaphoid fracture is treated with closed reduction and osteosynthesis is performed with the Herbert bone screw. The percutaneous technique preserves the inter- and intracarpal ligaments, the vascular supply and the articular surfaces of the scaphoid. Osteosynthesis by the Freehand method is sufficiently stable to withstand early functional moves on the first postoperative day.
