Description
Christian Liebsch, Peter Obid, Morten Vogt, Benedikt Schlager, and Hans-Joachim Wilke test how the length of spine hardware strains nearby joints. Their 2024 lab study uses six human spine samples with full rib cages from young adult donors. Surgeons pick hardware length by deformity type and personal habit.
Pure bending loads were applied while cameras tracked motion at every segment. Thin sensors logged pressure inside lower back discs from the first to the fifth level. Longer hardware raised motion most at segments above the top screw, above all in side bending. Disc pressure shot up at braced levels, in one case by fivefold and more. The authors advise bracing as short a span as is sound.
