Three synthetic biomechanical models were used: a synthetic osteoporotic diaphysis (model 1), a 3-layer biomechanical polyurethane foam with 50\u201310\u201350 pounds-per-cubic-foot layering (model 2), and a 3-layer polyurethane foam with 50\u201315\u201350 pounds-per-cubic-foot layering (model 3). For the cadaveric metaphyseal model, 3 sets of cadaveric tibial plafonds and 3 sets of cadaveric tibial plateaus were used. A plate with sensors between the bone and plate interface was used to measure compression force during screw tightening in the synthetic bone models, while an annular load cell that measured screw compression as it slid through a guide was used to measure compression in the cadaver models.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>Across all synthetic osteoporotic bone models, the BSF demonstrated greater maximal compression force before stripping compared with the TBS [model 1, 155.51 N (SD = 7.77 N) versus 138.78 N (SD = 12.74 N), <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.036; model 2, 218.14 N (SD = 14.15 N) versus 110.23 N (SD = 8.00 N), <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001; model 3, 382.72 N (SD = 20.15) versus 341.09 N (SD = 15.57 N), <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.003].
