b'ARTICLEUnderstanding the prevalenceThe true extent of osteoarthritis in small pets may surprise many clinicians. In rabbits, retrospective analysis of radiographs has suggested a prevalence of just over 40%. 1Even more telling is a UK study that evaluated computed tomography (CT) scans of rabbits admitted to a veterinary hospital: 19.6% showed evidence of OA in at least one joint, yet clinical signs were recorded in the notes for only 14.8% of affected animals. 2This substantial gap highlights how easily the condition can be missed.Giant rabbit breeds face particular risk, sometimes developing clinical signs as early as two years of age. The hip and hock joints are frequently affected, and spinal spondylosis is commonly observed. But herein lies the challenge: as prey species, rabbits are masters at hiding discomfort, making signs subtle and easily overlooked even by the most attentive owners.Guinea pigs are similarly affected, with tibiofemoral OA identified as one of thepain control at its heart.
