Cauda equina compression from lumbosacral malarticulation and malformation in the dog.

Compression of the cauda equina from subluxation, stenosis, or spondylosis of the lumbosacral articulation was found in 20 dogs, 13 of which were German Shepherd Dogs or crossbred German Shepherd Dogs. Pain, posterior paresis, and urinary or fecal incontinence were the most frequent problems associated with the compression. Dorsal laminectomy was performed on 13 cases, with good to excellent results on 10 of these.
