Spinal osteoarthropathy
Spinal osteoarthropathy (also known as Charcot's disease) is a rare disease affecting reptiles (including snakes and lizards) which causes abnormal bone growth on vertebrae, giving the reptile a lumpy appearance. The growth of animals with this disease is limited (a python may only grow 2 feet (61 cm) long), and their life spans are greatly shortened.[1] The movement of reptiles with this ailment appears jittery and wooden, and the head movement will be greatly restricted.
