Evaluation of a standardised radiographic technique of the equine hoof.

This study describes and evaluates a standardised radiographic process used for imaging horse hooves. High accuracy and repeatability were achieved with this technique, showing its potential as a tool for quantitative hoof measurements.

Background

• The primary goal of this research was to describe and assess a standardised radiographic method for obtaining images of horse hooves from two different perspectives — the lateromedial (LM) and the dorsopalmar (DP) views.
• Radiography of horse hooves is often used to make diagnostic decisions. For research purposes, it is critical that these images be of high quality and accuracy.

Methodology

• The researchers obtained ten radiographs from each of the two views. These came from one cadaver limb and from both front feet of a standing horse – this was done to ensure that the radiographic technique could be reliably repeated.
• The radiographic method requires easily adjustable and portable equipment, alongside strictly defined external radio opaque markers on the hoof capsule.
• The obtained radiographs were then digitalised, processed, and analysed using a software package called Metron PX. In the LM view, 13 parameters were measured, while in the DP view, 10 specific parameters were measured.

Results

• The results indicated a high degree of accuracy and repeatability, with few exceptions.
• The measurements of these parameters displayed a coefficient of variation that was less than 0.05, indicating a low variability between measurements thus showing a high level of precision.

Conclusion

• The study found that this standardised radiographic technique provides excellent accuracy and repeatability for both the LM and DP views.
• The technique’s ease of use combined with its precision and reliableness suggests it could provide an adequate tool for quantitative assessment of horse hooves both at an individual level and across multiple individuals.
