Treatment of lumbosacral discospondylitis by surgical stabilisation and application of a gentamicin-impregnated collagen sponge.

This report describes a case of lumbosacral discospondylitis in a two-year-old boxer dog. The dog had been presented with chronic hindlimb lameness and signs of lumbar spinal pain. The diagnosis was confirmed with a magnetic resonance imaging scan and positive blood culture. Following unsuccessful conservative management, the dog was treated with surgical stabilisation using screws and polymethylmethacrylate, and implantation of a gentamicin-impregnated collagen sponge into the L7-S1 disc space. This technique has not previously been described. The dog had a successful long-term outcome with complete resolution of clinical signs.
