Abstract
We have studied the biomechanical stability in vitro of three different Kirschner (K) wire configurations in three types of simulated scaphoid waist fractures. The fractures were created with a saw in Sawbones models. There were three fracture patterns: perpendicular to the long axis of the scaphoid model; and 30° and 20° oblique to that. Two 1.2 mm. K-wires were used in each scaphoid. The three configurations were: parallel; 20° oblique; and crossing. The oblique or crossing configurations of K-wires were the most stable depending on the fracture pattern.
