abstract

Elderly patients represent the fastest growing population in sustaining acetabular fractures. Anterior column with posterior-hemitransverse (ACPHT) fractures are one of the most common types of acetabular fractures seen in the elderly. Extrapelvic and intrapelvic fixations are used as surgical treatments, with extrapelvic being less invasive and intrapelvic providing, theoretically, a mechanical advantage. 10 fractured and fixated cadaveric pelvises underwent biomechanical testing to compare the two methods. On average, pelves with intrapelvic plates performed better for all test metrics with statistical significance (p < 0.05) reached for yield force, maximum force, and plastic energy. From these results it might be concluded that the intrapelvic plate does not begin contributing significantly towards the strength of the acetabulum until higher loads are reached. However, reoccurring trauma is not unusual, particularly among fall victims. An intrapelvic plate could prevent reprotrusion of the acetabulum in such scenarios.
