Disorder - Calcification of intervertebral discsOrgan Systems Involved
Intervertebral Disc Disease
Affected dogs have abnormal deposits of calcium in the soft tissue of the intervertebral discs of their back and neck (the cushioning discs between the vertebral bones of the spine); this makes them prone to disc herniation, where the disc ruptures into the spinal cord causing pain, weakness and paralysis.
Affected dogs will show varying symptoms depending on the amount of calcium deposited, and its location along the spine (most commonly in the mid-back region). They may show neck and back pain, reluctance in jumping and walking up stairs, weakness, and they may be unable to support weight on their back limbs. Calcifications are most noticeable around the age of 12 -18 months, from which point they may increase in number or decrease without degenerating further. The possible effect of this disease is the rupture of the disc into the spinal cord. This causes increasingly severe signs including back pain, wobbly gait, weakness, loss of sensation in the legs and muscular paralysis. Other consequences of the ruptured disc and spinal nerve damage include severe bleeding inside the spinal cord and lack of bladder control.
