## Abstract Internal fixators are a new class of implants designed to preserve the periosteal blood supply of the bone. In contrast to conventional plate fixation in which the screws have spherical heads and are loaded mainly by axial pullout forces, screws in internal fixators are βlockedβ within

## Abstract The use of polymethylmethacrylate (PMMA) bone cement to augment hip screws reduces cutβout risk but is associated with an exothermic reaction. This __in vitro__ investigation evaluated the risk of thermal necrosis when augmenting the implant purchase with PMMA. A pilot study analyzed th
