A finite element study performed in the University of Technology Eindhoven, NL, has been published in The Spine Journal. The aim of the study was to predict whether the reduction of misaligned posterior instrumentation might result in clinical complications directly after reduction, and during a subsequent physiological flexion movement.
The authors´ conclude that the FE analysis in this study demonstrates the importance to minimize the residual mismatch between spinal rod and pedicle screw head during posterolateral fusion surgery in the lumbar spine.
Avoiding the need for reduction procedures may reduce the loads both on the posterior construct and on adjacent hard and soft tissues.
”We postulate that clinical complications secondary to unfavorable biomechanics could be reduced by ensuring proper screw rod construct alignment such that minimal external and unintended forces are required for connecting the spinal rods to the headsof the pedicle screws”.
