Root Signature Pain
Linda wants to know more about root signature pain? How many do you see with the rear legs affected vs. the front legs?
We do see root signature in both the pelvic and thoracic limbs, but it is more common in the thoracic limbs. The reason is due to the fact that it is more likely to have a disk rupture in the cervical spine versus the lower lumbar spine.
The majority of the time lameness is due to an orthopedic disease and not a neurological disease. However, if an orthopedic cause cannot be identified, "root signature" should be considered.
There are several things that can irritate the nerve roots and cause "root signature," but the top two are herniated/protruded intervertebral disks and tumors. If "root signature" is suspected in your dog, the two ways to proceed are either conservatively with rest and medications or to have advanced imaging performed to identify the exact cause. This decision depends on multiple variables including history and exam findings (severity of pain and concurrent neurological deficits) and is best discussed with your veterinarian.
