Ununited accessory caudal glenoid ossification centre and associatedjoint mouse as a cause of lameness in a cat

摘要

Case summaryA 16-year-old neutered female domestic shorthair cat was evaluated for chronic lameness of the right thoracic limb. On clinical examination, pain was localised to the right glenohumeral joint. Radiography and arthrography of the right glenohumeral joint revealed an ununited accessory caudal glenoid ossification centre, abbreviated here to ununited caudal glenoid (UCG), and a joint mouse. The UCG and attached joint mouse were removed via arthroscopy and this resulted in complete resolution of the clinical signs. The cat was euthanased 3 years later, for an unrelated cause, having shown no recurrence of lameness.
