Diagnostic imaging of equine thoracolumbar disorders Equine thoracolumbar conditions represent a major cause of poor performance and locomotor disorders in sports and race horses. Advances in diagnostic imaging during the last 15 years allow today to diagnose most equine back lesions in the standing sedated horse. Radiography is the first choice imaging modality due to its high diagnostic performance. Ultrasonography is a complementary modality to further investigate back soft tissues and the caudal lumbar area not evaluable radiographically in the standing horse. Bone scintigraphy is a more complex and expensive technique and is usually dedicated to complicated clinical cases. The most frequent injuries diagnosed using these 3 modalities are kissing spines, osteo-arthrosis of the synovial intervetebral joints, vertebral spondylosis and muscle injuries. Clinical significance of these lesions should be interpreted with care considering the clinical signs exhibited by the horse but also its sports or racing use.
