Abstract

Flying scapula, or dorsal scapular displacement, is a rare myopathy in cattle characterized by the abnormal protrusion of the scapula due to rupture or degeneration of the serratus ventralis muscle. This paper presents a clinical case of a 4.5-year-old Gir-cross cow exhibiting abnormal stance and difficulty in walking following parturition and subsequent trauma. Clinical examination revealed bilateral cranial protrusion of the scapula, abduction of the thoracic limbs, and a large ventral swelling near the manubrium. Hematological analysis indicated neutrophilia with leukopenia, and serum biochemistry showed elevated AST levels. Radiography confirmed scapular displacement without fractures, while ultrasonography of the swelling revealed a hypoechoic fluid-filled area. Diagnosis was consistent with degeneration of the serratus ventralis muscle and a concurrent thoracic abscess. Treatment involved abscess drainage, systemic antibiotics (enrofloxacin), anti-inflammatory therapy (meloxicam), fluid therapy, and supplementation with selenium and vitamin E. The clinical signs and findings aligned with those reported in nutritional myodegeneration, though selenium and vitamin E levels were not directly assessed. Contributing factors likely included trauma and potential nutritional deficiencies. The case underscores the importance of nutritional management, injury prevention, and supportive care in the diagnosis and management of this condition.
