A Case of Disassociation of a Modular Femoral Neck Trunion After Total Hip Arthroplasty
Sporer, Scott M; DellaValle, Craig; Jacobs, Joshua; Wimmer, MarkusHip
Modular femoral heads offer the advantages of increased intraoperative flexibility through the adjustment of leg length and offset, whereas a modular femoral neck can also allow independent adjustment of femoral anteversion. Despite the potential advantages of hip systems using increased modularity, these component designs also offer a greater number of junctions through which problems may occur. This case demonstrates the potential for dissociation of a Morse taper between a modular femoral neck and stem.
