If the heavy hindlimbs are allowed to thrust unsupported, they can exert significant '''stress''' upon the animal's lightweight skeleton which can result in '''skeletal and spinal cord damage'''.

It is a common condition is '''indoor reared, poorly fed rabbits'''. The close confinement leads to weakening of the bones and muscles due to disuse atrophy, and the absence of sunlight can exacerbate a vitamin D3 deficiency in a poor diet along with calcium deficiency creating '''metabolic bone disease'''.

'''Radiography''' helps to assess trauma to the vertebrae. Fractures most commonly occur at the level of the 7th lumbar vertebra.

The '''quality of life''' for these animals should be taken into account, and '''euthanasia''' may be the best option in some cases.

The '''prognosis is poor''' when the spinal cord has been severely damaged or severed and when vertebral alignement is not maintained. Where there is only severe bruising and inflammation, supportive care and time may lead to an improvement in signs and an '''adequate quality of life'''.

As responses vary, each case should be '''treated individually'''.
