The incidence and severity of intercarpal ligament damage in the equine carpus.

This research examines the occurrence and severity of damage to the intercarpal ligament in horses through a review of arthroscopic findings in 76 horses. The data showed varying degree of ligament damage and some association between ligament damage and the severity of articular cartilage damage.

Study Overview

• The research involves a review of arthroscopic findings from 76 horses, with a total of 104 intercarpal joints being examined.
• The main focus of the study was to establish the incidence and severity of changes to the medial intercarpal ligament, a crucial structural component in a horse’s carpus or wrist area.
• A significant part of the research aimed to identify the connection between ligament damage and osteochondral chip or slab fractures, which often necessitate arthroscopic surgeries in horses.

Research Findings

• The study found that 43 joints in 35 horses demonstrated visible damage to the intercarpal ligament. The intensity of the damage varied, ranging from mild fraying of the ligament edges to complete disruption of all its fibres.
• This translates into an incidence rate of 41%, indicating that nearly half of the joints studied had some form of ligament damage.
• In nine instances, the primary reason for the arthroscopic examination was for further diagnostic procedures. However, during these examinations, ligament damage was also present in all the cases.
• For horses that underwent arthroscopic surgery for the treatment of osteochondral chip or slab fractures, a degree of correlation was noted between the severity of articular cartilage damage and the presence and severity of ligament damage.

Conclusion

• The research provides useful insights into the incidence and severity of intercarpal ligament damage in horses. With a high incidence rate, it’s clear that such a condition is relatively frequent in equine species and warrants further investigation especially in the context of articular cartilage damage.
• The observed correlation between the severity of cartilage damage and ligament damage suggests a potential association or cause-effect relationship between the two. This could be a focal point for future research and could help design more effective diagnostic, preventive and treatment strategies in veterinary medicine for horses.
