case_images: A) Tarsal swelling due to the superficial digital flexor tendon dislocation of left leg. B) Lateral radiograph of the tarsal joint of the left foot. The calcaneus bone appears to be normal. At the same time, mild bone spavin symptoms can be seen in the distal inter-tarsal joint of tarsus (arrow).

case_images: On palpation of the tarsal joint of both legs, the displacement of the SDFT to the outside and its swelling could be detected (Fig. 1A). In the radiography of the tarsal joints, the calcaneus bones did not show significant abnormalities except soft tissue swelling; but, between the central and 3rd tarsal bone (distal inter-tarsal joint) of the tarsus, the osteophytes formation was observed mildly, indicating a slight bone spavin in distal inter-tarsal joint of tarsus (Fig. 1B).
case_images: Sonogram of the longitudinal view of the tarsal joint of the left leg. The symptoms of bursitis are evident in the form of thickening of the synovial layer and effusion inside the calcaneus bursa. The arrow shows the fluids inside the bursa

case_images: In the left leg, in addition to tendonitis, effusion in the calcaneus bursa and inflammation of the bursa were observed (Fig. 2).
case_images: Transverse sonogram of the proximal area of the tarsal joint of the right leg at the site of the calcaneus bone. Hypoechoic areas and calcification are seen as hyperechoic spots in the superficial digital flexor tendon (arrows), indicating chronic tendonitis

case_images: In ultrasonography of the right leg, the signs of chronic tendinitis were evident in the form of tendon calcification and fibrous tissue formation around the SDFT (Fig. 3).
