00:07In the thoracic spine, if the sclerosis is more than 70 degrees, it will significantly
00:13affect the heart and the lung function. In the lumbar spine, different from the thoracic
00:21spine is the presence of this important nerve to our lower limbs. So if the sclerosis increases,
00:29it can pinch on the nerve and cause very significant nerve pain or even nerve dysfunction. The concept
00:37is called growth modulation. It means we actually, let's say a curve that is 50 degrees, immediately
00:45after the correction by the tether, we probably correct down to 20. And then if this child
00:53still has growth potential left, the growth, instead of making the sclerosis worse, can
00:59further improve. Because I perform this on the, we call it the convex side. So that means
01:07this part cannot grow anymore because of the pressure introduced by the band. But this
01:12part is still growing. So as this child grow, it goes this way. So this is the growth modulation.
01:18We actually have the possibility to treat sclerosis not using big incisions, but a few small
01:25pokes. So the recovery rate typically for, let's say a single thoracic sclerosis, most patients
01:32stay one or two nights. Then you're actually seeing everything through the scope. So there
01:37is a cap just like the traditional screws. So there's a screw and then there's a cap that
01:42can tighten this tether to the screws. So after I tighten this one, then this is passed to this
01:49one. So after I lock it here, you can see that as I do this, you see that? See, I'm
01:55actually
01:55compressing these two. And here, there's a tension gauge. Basically summarize it. It's
02:02minimal invasive, it's growth modulation, it's motion preservation.
