Table 2 Mean and standard deviation of absolute and normalized values for each investigated variable. There was no significant difference between groups for all investigated variable except for the normalized stiffness

From: Variable fixation promotes callus formation: an experimental study on transverse tibial osteotomies stabilized with locking plates
