  1. Equine Calcaneal Bursitis Christina Copple, DVM Radiology Resident Monday September 21, 2009 Accession #’s 120984 & 120974

  2. “Freck” 16yr old Arabian gelding • Intermittent left hind lame • Effusion at lateral aspect of right hock (tarsus) and reluctant to pick up right foot • Moderate to severe swelling over tuber calcaneus of left hock (tarsus) http://www.horse-wallpaper.com/backgrounds/white-arabian-horse.jpg http://media.photobucket.com/image/swollen%20equine%20hock%20joint/Glacierpt/Hanyshock002.jpg

  3. Anatomy of Tarsus and Calcaneal Bursa 1 – Superficial Digital Flexor Tendon (SDFT) 1’ – Calcaneal Bursa 2 – Gastrocnemius 4 & 2’ – Tuber Calcaneus Dyce, et al. Textbook of Veterinary Anatomy 3rd ed. 2002. pg 614 & pg 615

  4. Radiograph of Left Tarsus Swelling and increased soft tissue opacity in region of calcaneal bursa Lateromedial projection

  5. Radiograph of Left Tarsus Two irregular & ill-defined lucencies in plantaromedial aspect of tuber calcaneus Dorsoplantar flexed projection

  6. Ultrasound of left calcaneal bursa, tuber calcanei and associated soft tissue structures SDFT Anechoic fluid-filled calcaneal bursa with thickened synovial lining Gastrocnemius tendon

  7. Ultrasound of left calcaneal bursa, tuber calcanei and associated soft tissue structures Defect in medial margin of SDFT with out pocketing of synovium into SQ tissues Tuber calcaneus

  8. Ultrasound of left calcaneal bursa, tuber calcanei and associated soft tissue structures Defects in periosteum and irregular surface of tuber calcaneus

  9. Septic Calcaneal Bursitis • Synovial fluid analysis – consistent with severe suppurative inflammation • Arthroscopy of left calcaneal bursa for lavage and debridement • Trauma results in hemorrhage and inflammation • Penetrating wounds are common • Sequela – tendon adhesions within bursa
