Research PublicationDesign concept of an extracortical implant for canine total hip replacement: A technical note
This technical note presents the Prime Hip Barrel-Plate System, an innovative extracortical, canal-sparing approach to canine total hip replacement. The system uses proximal metaphyseal fixation through a controlled femoral neck tunnel combined with a lateral extracortical plate, preserving the femoral intramedullary canal. The paper describes the implant concept, biomechanical rationale, proposed surgical technique, potential advantages, limitations, failure modes, and future clinical applications. The design aims to reduce stress shielding, eliminate femoral broaching risks, preserve future revision options, and provide proximal load transfer while maintaining the integrity of the femoral canal.
