Purpose To compare the residual range of motion (ROM) of cortical screw (CS) versus pedicle screw (PS) instrumented lumbar segments and the additional effect of transforaminal interbody fusion (TLIF) and cross-link (CL) augmentation. Methods ROM of thirty-five human cadaver lumbar segments in flexion/extension (FE), lateral bending (LB), lateral s...
