Busuttil T, et al. - Data were analyzed to study comparatively the biomechanical strength of lag screw-only fixation of anterior column posterior hemi-transverse (ACPHT) acetabular fractures to standard anatomical plate fixation in geriatric acetabular fractures. They recorded the resistance of 1.57 × 106 N*cycles in the plate fixation group and 3.17 × 106 N*cycles in the screw fixation group with regard to energy absorbed until failure. They observed the failure of all plate fixation specimens with a break-out of the posterior-column screw in the quadrilateral wing of the anatomical plate within a maximum load of 1750 N. They concluded that both designs resisted adequately to forces as expected under the physiologic situations.
