Bone cysts are found in different joints (Stifle, fetlock, coffin joint, elbow and shoulder joint, etc) and some of these do have connection with the joint. In some cases a surgical treatment is necessary in order to achieve full healing. Some are treated arthrosciopically and other are drilled out and filled up with a bone graft under Computer Tomographic (CT) guidance. These interventions are technically demanding. Another possible surgical technique is the insertion of a resorbable or non-resorbable screw through the cyst.
