A proximal cortical bone screw was placed in lag fashion with the limb unloaded (simulated recumbent repair) and loaded to 38% of body weight (range, 375\u2013568\u2009kg; simulated standing repair). Changes in fracture gap width were assessed on computed tomography (CT) images and with intraplanar force\u2010sensitive resistors measuring voltage ratios (V<jats:sub>\u25b3<\/jats:sub>) between loaded recumbent (R\u20101) and standing repair simulations (R\u20102).
