Chip fractures in the carpus of the horse: a radiographic study of their incidence and location.

The research article investigates the prevalence and location of chip fractures in the carpal bones and the distal end of the horses’ radius bone, with specific focus on the radial carpal bone, intermediate carpal bone, and 3rd carpal bone.

Study and Findings

This study was conducted to determine the incidence and the locations where chip fractures in the carpus most often take place in horses. The results shows:

• The radial carpal bone, which is part of the horse’s wrist analogous in humans, was found to be the most vulnerable, with 50% of chip fractures occurring here. This prevalence may suggest that this bone has a high level of stress or pressure, potentially due to horse activities such as jumping or running.
• Chip fractures were less frequently discovered on the distal end of the radius (the horse’s equivalent of the lower arm bone in humans) as well as the intermediate carpal and 3rd carpal bones.
• Nine key locations were identified where these fractures are most commonly found. The study, however, did not provide specific details on the exact locations.

Observations on Horse Limbs

The research further disclosed interesting findings related to the horse’s front limbs. It showed:

• A higher number of chip fractures were reported on the horse’s right carpus, which is the equivalent of a human wrist. This may suggest that neglecting left-vs-right use in activity, horses potentially impose more stress or load on the right front limb.
• The study also observed that slab fractures of the 3rd carpal bone were more frequently found on the right front limb. Slab fractures are a type of fractures where a large piece of bone separates from the main bone, which could be due to severe stress or abrupt trauma.

These findings provide important insights into the health and well-being of horses, potentially aiding in better equine care and treatment procedures related to carpal bone fractures.
