Thoracolumbar junction injuries after motor vehicle collision: are there differences in restrained and nonrestrained front seat occupants?
It is likely that the high incidence of neurological deficit in the nonrestrained front seat motor vehicle occupants who had a TLJ injury was mostly due to the high incidence of flexion-distraction/fracture-dislocation injuries. This retrospective study indirectly shows the efficacy of three-point seat belt systems in reducing the severity of a TLJ injury after an MVC. Compression/burst fractures still occur in restrained front seat occupants, however, and elucidation of the injury mechanism of such axial loading fractures may be important to improve safety further for automobile occupants.
If a perfect centrally positioned tibial tunnel is drilled, a real risk for femoral notch impingement exists depending on the size of the tibial ACL footprint and surgery-related factors. Therefore, in anatomical tibial tunnel placement in single bundle ACL reconstruction surgery, particular attention should be paid to size of the tunnel and drill-guide angle to minimize the risk of femoral notch impingement.
