Plantar necrosis is a catastrophic complication that may be associated with injury to the dorsal pedal artery or perforating metatarsal artery. Application of a bone plate to the medial aspect of the hock should be performed with care during tarsal arthrodesis, particularly where the tarsometatarsal joint is debrided of cartilage. Strict attention to surgical technique and proper postoperative coaptation is critical to reduce the potential for complications with tarsal arthrodesis.

Three adult large breed dogs were evaluated for chronic forelimb lameness. Clinical examination localised pain to the area of the shoulder joint. Traditional imaging methods, including radiography, arthrography and ultrasonography, were unrewarding. Arthroscopy performed via a lateral portal demonstrated complete tears of the proximal part of the lateral glenohumeral ligament in all cases. Two of the three cases responded to treatment with intra-articular methylprednisolone and rest with a resolution of the lameness, while the third failed to improve. Surgical intervention in this third case involved lateral capsulorraphy, and re-examination at five weeks postoperatively showed the dog to be without lameness. Tearing of the lateral glenohumeral ligament should be considered in the differential diagnosis of shoulder lameness. Surgical stabilisation should be considered in cases refractory to conservative treatment.

Ultrasound images of intervertebral discs relate well to their pathologic condition. In addition, ultrasound is able to locate specific pathologic defects.
