The short answer is yes of course. Loss of spinal height is loss of height. There was a limb lengthening surgery for the spine but it was only for immature pigs. And the growth achieved was very small. There is a growing rods technique for scoliosis patients but the lengthening achieved according to Spinal Lengthening With Magnetically Controlled Growing Rods is something on the order of millimeters. But that adds up.

The intervertebral discs are a component of height. Some people have claimed on forums to get taller in the spine via stretching and I would love to see those claims validated in some way.

Here’s the regeltec website.

Here’s a video with more about the technique:

There was a clinical trial but no results have been posted. I could find some data that the Hydrafil reduced backpain but no data on the impact on height. Of course how much height is added would vary on how much the disc is degenerated. And it would be interesting if you could somehow overfill the disc in order to add height above capacity.

There’s definitely a cost issue as there’s a lot of discs to inject hydrafil into. But there’s no surgery and you just have to inject it that should alleviate the cost. So it may not break the bank but it would probably be a significant sum like all surgical procedures.

But it may be a good non-invasive way to add a little bit of height?
