Skeletal conditions in snakes

Snakes have evolved to have a very muscular structure so they move very efficiently along the ground and up into trees without the use of legs. Most snakes have no legs at all, however some snakes have vestigial (remnants) of back legs around the vent area.

Movement is facilitated by contractions of muscles and rippling the body in an s-shape. The body of the snake is protected by ribs and these are present all the way down to the level of the vent.

Spinal osteoarthropathy is a condition seen in snakes where the backbone becomes infected with bacteria. The body tries to fight the infection which then leads to the bones fracturing and trying to fuse. This condition gives the snake a ‘lumpy’ appearance.

If you suspect your snake has this condition you should take him to see your veterinarian as soon as possible.
