The importance of early radiological assessment in juvenile canine lameness

Radiography remains the cornerstone in evaluating lameness in small animal practice, and early identification of pathological musculoskeletal conditions is imperative, particularly in the juvenile or skeletally immature patient. Delays in diagnosing conditions affecting longitudinal bone growth or joint congruity can lead to significant growth-related complications. This article discusses the radiological aspects of key orthopaedic conditions in young canine patients, focusing on the importance of early diagnosis and intervention. A narrow window often exists to treat the cause before the onset of arthritis and chronic lameness. The discussion centres on selected conditions, such as hip and elbow dysplasia, osteochondrosis, humeral intracondylar fissures, retained endochondral cartilage cores, hypertrophic osteodystrophy and physeal trauma. The veterinarian's role in achieving timely and accurate diagnosis is emphasised. Common pitfalls and normal variations are also addressed.
