This case report describes the clinical and diagnostic imaging findings, treatment, and outcome of a three-month-old Thoroughbred foal referred for the evaluation of severe left forelimb lameness and presents the acquisition of a novel radiographic projection of the scapula used to achieve the diagnosis. No abnormalities were found with the standard radiographic examination of the left shoulder. Ultrasound and a dorsal 45° lateral‐ventral lateral oblique radiographic view were performed to evaluate the body of the left scapula. A longitudinal, minimally displaced fracture of the infraspinous fossa was diagnosed with this projection that was not detected in the routine projections. Ultrasound was used in conjunction to confirm the diagnosis, assess the displacement of the fracture in the frontal plane, and evaluate soft tissue damage. The foal was treated conservatively with anti-inflammatory drugs and stall rest. A radiographic follow-up and clinical reassessment were performed, and the horse appeared sound, no atrophy of the region was appreciated, and no radiographic abnormalities were found.
