Spinal decompression in a black bear.

A 17-year-old black bear was examined because of posterior paralysis. Radiography revealed a narrowed disk space at T10-11, indicating a ruptured intervertebral disk. Subsequently, a dorsolateral hemilaminectomy was performed. Recovery from paralysis was slow because of the size of the animal (127 kg) and lack of appropriate physical therapy. When evaluated more than 1 year later, however, the bear had no signs of neurologic deficits.
