Abstract
CASE SUMMARY: A 7-year-old male castrated Ragdoll cat was presented for chronic shoulder instability after a previous medial luxation of the right shoulder. Upon examination, there was palpable instability of the glenohumeral joint and an increased abduction angle. Surgical stabilisation was elected due to lameness and instability after closed reduction, rest and medical management. A low-profile bone-anchor and a ligament prosthesis were used to stabilise the glenohumeral joint with minimal disruption to the cat's natural shoulder stabilisers. Clinical signs resolved after surgery and the cat remained non-symptomatic at the 12-month follow-up. RELEVANCE AND NOVEL INFORMATION: Feline shoulder luxation is rarely described in the veterinary literature. To the authors' knowledge, this is the first report describing stabilisation of the glenohumeral joint in a cat using a bone anchor and a ligament prosthesis.
