Lumbosacral degenerative stenosis in the dog. The results of epidural infiltration with methylprednisolone acetate: a retrospective study.

Thirty-eight dogs with Hansen type II lumbosacral disc protrusion were treated with epidural infiltration of methylprednisolone acetate between the seventh lumbar vertebra and the sacrum. Epidural infiltration was carried out under C-arm fluoroscopic guidance at standardised intervals for the first three treatments and later on demand. Retrospective evaluation by owner questionnaire found that 79% of the animals were considered to have improved, and 53% were totally cured. Epidural infiltration with methylprednisolone acetate has a clinical outcome comparable to decompressive surgery and can be safely used as a less invasive alternative.
