Biomechanics of Fracture Fixation

Load sharing vs load bearing; absolute vs relative stability; primary vs secondary healing. Plates: compression (DCP/LCP in compression) vs bridging (relative stability); working length matters. Nails: intramedullary load‑sharing devices; reamed vs unreamed; interlocking controls length/rotation. External fixation: pin density/configuration, frame stiffness; circular frames allow controlled micromotion. Screw biomechanics: lag by technique vs design; pull‑out strength depends on cortical engagement and size.
