Arthroscopic examination of the elbow of a 2 year old Rotweiller dog with foreleg lameness. Multiple fragments of the coronoid process are removed followed by arthroscopic subtotal coronoidectomy (removal of part of the coronoid bone).
These loose fragmented coronoid process lesions which move on weight bearing, are a cause of persistent pain & lameness. Both the fragmented cartilage lesions and the underlying yellowish coloured avascular subchondral bone will be removed arthroscopically.The yellowish coloured avascular bone can be seen on the underside of the white cartilage covered fragments and its exposure within the joint will lead to significant DJD. Avascular bone is bone which has lost it blood supply.
