Summary
# Editorial Summary: TMJ Anatomy in Young Horses via CT Imaging Until this 2008 study, clinicians lacked a standardised computed tomographic protocol and clear anatomical reference for the equine temporomandibular joint (TMJ)—a region notoriously challenging to evaluate when clinical problems arise. Rodríguez and colleagues established both a reproducible CT imaging technique and detailed anatomical interpretation of normal TMJ structures in young horses, creating an essential diagnostic foundation for practitioners. By systematically documenting the appearance of articular surfaces, condylar morphology, disc position, and surrounding soft tissue anatomy on CT images, the authors provided a baseline against which pathological changes could be reliably identified. This standardised approach has significant implications for farriers and veterinarians managing cases of poor performance, asymmetrical loading, or apparent head carriage issues related to mandibular dysfunction, since accurate diagnosis now depends on recognising deviation from normal CT anatomy. The work fundamentally improved our diagnostic capability in a region where clinical examination alone is insufficient, enabling more evidence-based treatment planning and intervention.

Practical Takeaways
- •CT is a valuable diagnostic tool for investigating TMJ problems when clinical examination is inconclusive or difficult
- •Understanding normal CT anatomy of the TMJ helps veterinarians identify pathological changes in horses with suspected joint disease
- •This protocol can guide veterinarians in performing and interpreting TMJ imaging in young horses presenting with regional signs
Key Findings
- •This study establishes a computed tomographic imaging protocol for evaluating the equine temporomandibular joint in young horses
- •CT imaging enables detailed visualization of TMJ structures and surrounding anatomy that are difficult to assess clinically
- •Provides reference anatomical data for normal TMJ appearance on CT to support clinical diagnosis of joint pathology
