Fig. 7From: Biomechanical evaluation of monosegmental pedicle instrumentation in a calf spine model and the role of fractured vertebrae in screw stabilityThe mean angular LZ of T12–L1 for all loading directions. a.The mean angular LZ of T12–L1 in the direction of flexion-extension. b. The mean angular LZ of T12–L1 in the direction of lateral bending. c. The mean angular LZ of T12–L1 in the direction of axial rotation. Error bars show standard deviation. *: P < 0.05; LZ: lax zone; PF: pedicle fixation; AL: after cyclic loading.Back to article page
