Fig. 8From: Comparison of compressive forces caused by various cannulated cancellous screws used in arthroscopic ankle arthrodesisScrew pressures in the cadaveric bone. All graphs show similar step-like shapes, with positive spikes followed by a gradual pressure decrease and plateau. Initial pressure was greater than 0 MPa (#). After achievement of maximum pressure, the screw torque was reduced but the pressure did not immediately decrease (##)Back to article page
