[Effect of soft tissue injuries on the biomechanics of sagittally symmetric thoracolumbar vertebral compression fractures].
Thoracolumbar compression-fractures were performed in an in-vitro model with a deformity of 9.7 degrees and 12.3 degrees. After stabilisation of the fracture additional soft tissue injuries were carried out by dissection of the posterior ligaments and ruptures of the nucleus and annulus of the intervertebral disc. The disc injuries led to a significant instability. The degree of kyphotic deformation showed the most distinct influence on torsion with an increase in range of motion of 64% (9.7 degrees) versus 181% (12.3 degrees).
