Posterior Femoral Single Limb Osteotomy for the Removal of Well-Fixed Modular Femoral Neck Components
Modular neck femoral components were introduced to optimize femoral neck anteversion, leg length, offset, and stability in total hip arthroplasty. However, concerns have been raised in recent years regarding early failure of these implants due to corrosion, pseudotumor, as well as fracture of the modular neck. Removing modular neck femoral implants is challenging as removal of the modular femoral neck leaves a proximally coated femoral stem level with the proximal bone of the femoral neck. We describe a posterior femoral single limb osteotomy (posterior cut of an extended trochanteric osteotomy) for the removal of a modular neck femoral component.
