Dislocation and Paralysis in Rabbits
Vertebral Fracture or Luxation in Rabbits
Normally, rabbits have very strong hind legs, which they use for hopping. Vertebral fracture or luxation (dislocation) of the limbs in rabbits is a common cause for weakness and paralysis of the hind limbs.
Sometimes, often because of improper handling, caged rabbits can twist their legs right at the junction of their lumbar spine and sacrum (base of the spine), which can result in a vertebral fracture. Some develop what is called a luxation, which is a dislocation that occurs at the lumbar L7 point (the lower spine), though fractures are far more common than luxations. This type of trauma may cause the rabbit to lose control of its bladder function, and possibly lose control of its bowel movements too.
Symptoms and Types
The signs and symptoms often depend on the severity of the condition. The following are some of the more common signs and symptoms:
The causes for vertebral fracture and luxation are varied and may include:
Because there are several possible causes for weakness and/or paralysis of the hind limbs, your veterinarian will most likely use differential diagnosis. This process is guided by deeper inspection of the apparent outward symptoms, ruling out each of the more common causes until the correct disorder is settled upon and can be treated appropriately. You will need to begin by providing a thorough history of your rabbit's health leading up to the onset of symptoms.
Other causes may include infection with Encephalitozoon cuniculi, central nervous system (CNS) infections, lesions on the CNS, metabolic diseases, or damage to the spinal cord. Your veterinarian will also test the spinal reflexes, along with taking radiograph images to assess any damage to the limbs. These will reveal the condition of your rabbit's spine, and whether the bone is in fact fractured, or has become dislocated from its socket. Magnetic resonance imaging (MRI) can be used to provide the most accurate images of what is going on with the limbs, but this type of imaging is not always available for small animals.
