Objective- To describe the normal sonographic images of the soft tissues of the dorsal and palmar aspects of the fetlock region in the draught horses.   Design- Descriptive study.   Animals- Five clinically and radiographically normal draught male horses were used during this study.   Procedures- Horses were examined both radiographic and ultrasound ante mortem and post mortem. Based on the pro...

OBJECTIVE To estimate prevalences of various presale radiographic findings and of presale arthroscopy in horses offered for sale at the 2006 Keeneland September yearling sale and to compare sales prices between yearlings with and without various presale radiographic findings or a history of arthroscopy. ANIMALS 397 Thoroughbred yearlings. DESIGN Cross-sectional study. PROCEDURES Presale r...

conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...

Ten patients with metacarpophalangeal joint locking of the thumb were studied. Three of them underwent surgical release. During surgery, it was found that the radial sesamoid was seated in a cartilage defect on the volar aspect of the metacarpal head. It appeared that the defect was created by the proximal edge of sesamoid. When the abductor pollicis brevis and flexor pollicis brevis muscles we...

OBJECTIVE This study aimed to present seven cases of avascular necrosis of the sesamoid and report the role of bone scintigraphy in the diagnosis of these patients. METHODS Seven patients with clinical suspicion of avascular necrosis of the sesamoid underwent three-phase bone scintigraphy with 30 mCi of (99m)Tc-MDP. RESULTS Most of the patients were young female adults with complaints of li...

Serum parathyroid hormone (PTH) and calcitonin (CT) levels in fractured racehorses were measured by radioimmunoassay. Racehorses with fracture of large bone such as the radius, third metacarpus, third carpus, digital bone or tibia, showed normal PTH level and elevated CT level in the serum. Serum PTH level was slightly higher in racehorses with sesamoid bone fracture compared to that of healthy...

Stress fractures occur as a result of microscopic injuries sustained when bone is subjected to repeated submaximal stresses. Overtime, with repeated cycles of loading, accumulation of such injuries can lead to macro-structural failure and frank fracture. There are numerous stress fractures about the foot and ankle of which a trauma and orthopaedic surgeon should be aware. These include: metatar...

The pelvic girdle was characterized by large, transversely-placed ilial wings. The femur was the longest bone of the skeleton and its fovea capitis was situated caudomedially between the epiphyseal line and the articular surface of the femoral head. A wedge-shaped patella articulated with the femoral trochlea. The bones of the crus were approximately half as long as the femur and consisted of t...
