Smaller Interval Distractions May Reduce Chances of Growth Rod Breakage Without Impeding Desired Spinal Growth: A Finite Element Study

Abstract: It was found that the shorter intervals of distraction led to reduction of stresses on the rod for same spinal height gain in two years.

“…In addition to that, the effects of frequency of distraction on maximum von Mises stresses on the rods were also studied. In our previous studies, we have shown the effect of distraction forces and the effect of frequency of distraction on different parameters using a normal juvenile spine [15,16]. These parameters included the stresses on the rod, optimal distraction forces, load at bone-screw interface, and sagittal contours.…”

“…This was produced using the T1-S1 normal ligamentous juvenile spine as a template [15,16]. Robinson and McMaster [17] reviewed 109 consecutive patients data on juvenile idiopathic scoliosis and then divided them into four categories: Groups 1, 2, 3, and 4.…”
