Under normal physiologic condition, the stress in posterior extension is greater than that in anterior flexion, but less than in neutral position.

Objective To determine whether reduction and plate fixation through anterior approach is effective in the treatment of distractive flexion (DF) injuries of the subaxial cervical spine.

Femoral component with slight flexion might prevent anterior femoral notching in bowing knees. It is important to evaluate the femoral bowing preoperatively, so as to prevent femoral notching.
