Why does George do this? S shaped spine

[GeorgeThePantherCham]

Hey! So I noticed recently that my 6 month old ambilobe panther Cham has been doing this sometimes when he’s basking, it’s not all the time but sometimes when I check the camera I have pointed in his cage he is basking under his lamp and his spine is S shaped.
His uvb is good, basking temp is always 83, I have it on a thermostat! He gets calcium powder with every feeding and calcium with D3 twice a month. His humidity as always good, around 50-60 during the day and 90-100 at night. His diet consists of crickets and discoid roaches daily, super and silk worms twice a week and sometimes some black soilder flies as well!

I’m very worried that this could be a sign of MBD as Google has told me, but it’s not an every day thing he only does it every now and then!
Attached is screenshots I’ve taken from his camera that’s pointed in his cage, one is his curved body and the other is how he normally looks.

Your male Furcifer pardalis spine in the second picture looks normal. However the first picture your male Furcifer pardalis spine looks contorted. I think your male Furcifer pardalis is most probably just stretching out while basking. I would keep an eye on how he grows and talk to a vet if you become worried.
