A technique for anchor plug salvage in the setting of a cold welded taper adapter following compress implant failure

Abstract

The Compress implant is used to achieve compliant fixation for endoprosthetic reconstruction during limb salvage. Failures, when they occur, are typically at the bone-implant interface. We describe a case of implant failure at a modular junction near a cold-welded taper adapter, blocking access to the spindle nut. Salvage of the anchor plug was performed in this case to avoid re-cutting the remaining bone.
