ObjectiveMost trauma centers place pelvic binders on unstable pelvic fractures for acute management and control of hemorrhage. It has been proposed that the binders be placed at the level of the greater trochanters of the femur. Our hypothesis was that application of the T-POD at this site would provide better immobilization of an unstable pelvic injury than a more cephalad location.MethodsUnstable pelvic injuries (OTA type 61-C1) were surgically created in 9 fresh whole human cadavers. Electromagnetic sensors were affixed to the intact and injured sides of the pelvis. A Fastrak, three-dimensional electromagnetic motion analysis device was used to determine the angular motion occurring at the fractured sites. Maximum displacements for sagittal, coronal, and axial rotation were recorded during application of the binder, while performing bed transfers, while logrolling, and elevating the head of the bed. The T-POD device was placed either over the greater trochanters or at the level of the anterior superior iliac spine as per manufacturer's recommendations.ResultsThere were no significant differences in the amount of motion produced during application of the T-POD at either location. There was less motion observed in all planes of motion during all maneuvers when the T-POD was placed at the level of the greater trochanters versus anterior superior iliac spine. During bed transfers, this was statistically significant in all planes. This was statistically significant while logrolling in the axial plane and the coronal plane during head of bed elevation.ConclusionsWe advocate the placement of pelvic binder devices at the level of the greater trochanters for improved control of the fracture in an unstable pelvic injury. This may result in improved control of hemorrhage, better access to the abdomen, and greater patient comfort.
