A Biomechanical Analysis of Spinal Instrumentation Systems in Thoracolumbar Fractures: Comparison of Traditional Harrington Distraction Instrumentation with Segmental Spinal Instrumentation

A total of 61 biomechanical tests were performed on 25 cadaveric spinal segments to investigate the comparative strengths of three instrumentation systems: 1) conventional Harrington distraction instrumentation (HRI), 2) segmentally wired Harrington distraction rods, and 3) Luque segmental spinal in
