When taking a DLPMO radiograph of a horse's fetlock, from which side should the x-ray beam come?

When capturing a DLPMO (Dorsolateral-Palmaromedial Oblique) radiograph of a horse's fetlock, it is essential for the x-ray beam to originate from the dorsal side. This approach is crucial because it allows for optimal visualization of the anatomical structures within the fetlock joint, particularly the relationship between the splint bones, cannon bone, and the joint space.

By directing the x-ray beam from the dorsal side, the radiograph can effectively highlight the areas of interest in the palmaromedial aspect while minimizing the superimposition of other anatomical structures. This method allows for a clear assessment of any potential pathologies in the fetlock joint, providing valuable insights into conditions such as fractures, osteitis, or soft tissue injuries.

In radiographic positioning, particularly in equine imaging, understanding the angles and perspectives from which the x-ray beam is directed is critical for achieving high-quality diagnostic images. The choice to come from the dorsal side is foundational in ensuring that the characteristics of a DLPMO view are met, helping veterinary professionals make accurate diagnoses.
