B2 or not B2? That is the question: a review of periprosthetic fractures around cemented taper-slip femoral components.

Aims: Periprosthetic fractures (PPFs) around cemented taper-slip femoral prostheses often result in a femoral component that is loose at the prosthesis-cement interface, but where the cement-bone interface remains well-fixed and bone stock is good. We aim to understand how best to classify and manage these fractures by using a modification of the Vancouver classification.

Methods: We reviewed 87 PPFs.
