Arthroscopic management of septic polyarthritis in a dog

A 4 1/2-month-old male Neapolitan Mastiff was presented with a history of severe non weight-bearing lameness, depression and anorexia, following 6 weeks of intermittent thoracic limb lameness that had deteriorated in the previous 72 hours. Haematogenous septic polyarthritis involving the right elbow joint and left glenohumeral joint was diagnosed, with blood and joint cultures revealing a Pasteurella species. Arthroscopy was utilised to facilitate joint evaluation and effect drainage of both joints. Clinical remission was achieved within 48 hours. Arthroscopy provided a minimally invasive yet thorough joint examination, lavage, and drainage of fibrinopurulent debris, thereby allowing early postoperative mobility and minimal morbidity.
