There are actually several different causes of hind limb paralysis that are semi common in hamsters. The first is called cage paralysis: the cure is to put him in a larger cage and try to help him to get more exercise and also you can get him vitamin D and E supplements.
The second is referred to as hind limb paralysis: usually seen in Syrian males around 6 months of age and is usually a hereditary condition and there is no cure. However, hind limb paralysis can be from constipation or falling.
If you are unsure of what scenario best fits your hamster, you should visit the vet to diagnosis and treat properly.
