IMAGING FINDINGS
The foal was sedated with xylazine (0.5 mg/kg IV) and radiographs of the
left scapulohumeral joint were obtained due to high suspicion of
fracture in the proximal forelimb, with a low-output radiographic
generator and direct digital radiography (Enduras Wireless- MinXray,
Cuattro Hub- Heska). Standard radiographic projections, including
mediolateral (ML) and cranial 45° medial-caudolateral oblique
(Cr45°M-CaLO) views of the left scapulohumeral joint were unremarkable
(Fig 1). A dorsal 45° lateral‐ventral lateral oblique (D45°L-VLO)
projection was obtained with the leg in flexion and the cassette placed
closest to the affected limb, with the radiographic beam at 45° with
respect to the sagittal plane of the horse (Fig 2). This image revealed
a longitudinal fracture of the infraspinous fossa, coursing from the
caudal border of the scapula, proximal to the neck, through the
infraspinous fossa, parallel to the spine, and exiting through scapular
cartilage (Fig 3). Ultrasound examination of the left scapula, performed
with a multi-frequency linear probe (GE Logiq E, 3-10MHz), identified a
defect in the surface of the infraspinous fossa, with no displacement of
the fracture in the frontal plane (Fig 4). Similar radiographic
evaluation performed six months later revealed complete healing of the
fracture.
