Which symptoms indicate the presence of Fracture or Luxation of the Lumbar Spine?

The presence of sudden onset of posterior paralysis is a significant indicator of a fracture or luxation of the lumbar spine. This symptom arises due to nerve damage or spinal cord injury resulting from the fracture or dislocation, leading to loss of function in the hindquarters. When the lumbar spine is compromised, the signals from the brain cannot effectively reach the hind limbs, resulting in paralysis.

In assessing spinal injuries, observing sudden impairments in motor function is crucial, as it suggests severe trauma that requires immediate veterinary attention. Other symptoms associated with spinal issues may include altered reflexes, changes in sensitivity, or even incontinence, but the key feature of paralysis in the hind legs is particularly telling of significant spinal trauma.

The other options—dry crusty scabs, soft feces and diarrhea, and excessive grooming behavior—are generally associated with other health issues such as skin infections, gastrointestinal problems, or stress and boredom, respectively, and do not directly indicate a spinal injury.
