DELAYED-ONSET SCIATIC IMPAIRMENT FOLLOWING TRIPLE PELVIC OSTEOTOMY

A 3-year-old, male Labrador Retriever developed bilateral sciatic nerv e dysfunction 18 months following bilateral triple pelvic osteotomy. O n surgical exploration, bilateral fibrous tissue entrapment of the sci atic nerves was found. There was significant and sustained improvement in clinical signs after relief of the entrapment. This case is notabl e because of the delayed onset of the neurologic deficit and is the fi rst report of this complication following corrective pelvic osteotomy.
