Modular tapered fluted stems: An accommodating option in the setting of femoral bone deficiency
Tapered, fluted, modular, titanium stems are being used more frequently for revision total hip arthroplasty to address femoral bone deficiencies. Mid- and long-term survivorship studies demonstrate that these stems are a durable implant design, while outcome studies show that they provide favorable patient satisfaction and function. Subsidence, implant fracture, and stress shielding are frequently encountered complications, which can be minimized through the use of meticulous preoperative templating, direct visualization of the femoral stem using mini C-arm fluoroscopy, and through the use of a kinked femoral implant. By using these techniques, a canal-filling implantation technique can be achieved.
