The use of modular components in total hip arthroplasty has increased in popularity. The advantages of modularity in hip arthroplasty include improved visualization during acetabular revision and restoration of proper hip biomechanics. Disadvantages include disassociation of components, failure at modular junctions, corrosion, and the generation of metal ions and debris. We present 2 cases that demonstrate the potential for modular neck fracture, requiring subsequent revision of well-fixed components.

The use of the cement-in-cement technique for femoral component revisions has been well described. The application of this technique in the management of selected Vancouver B2 periprosthetic femur fractures, after careful preoperative and intraoperative evaluation, offers a novel alternative that is rapid and technically less demanding, with resulting decreased blood loss and decreased risk of iatrogenic fragmentation of bone during cement removal.
