Fractures of the central and third tarsal bones in horses.

This research paper investigates the cases of 11 horses with fractures in their central or third tarsal bones, aiming to assess their diagnosis, treatment effectiveness, and prognosis. The larger context of the study is to analyze the outcomes of non-surgical treatment and to hypothesize on the advisability of the surgical route.

Study Sample and Context

• The study centered around the case histories of 11 horses, all aged between 2 to 4 years, that suffered fractures in their central or third tarsal bones.
• Most of these horses (9 out of the 11) belonged to the breed of Standardbreds, while the remaining two were Thoroughbreds.
• All these horses received their injuries while they were being exercised at race speed.

Difficulty in Diagnosis

• Diagnosing this kind of fracture posed a significant challenge. The diagnosis was typically made during the referral examination which occurred sometime after the injury.
• One tell-tale sign often discovered was the distention of the tibiotarsal joint, usually associated with a fracture of the central tarsal bone.
• Some fractures required local anesthetic injections or multiple radiographic views for accurate diagnosis. However, even with these measures, not all fracture planes could be identified radiographically.

Evaluation of Treatment and Prognosis

• The prognosis for horses to return to racing was generally poor. The conventional non-surgical treatment regime, involving prolonged rest, appeared to be ineffective in restoring the horses to athletic soundness.
• Only one horse, treated using lag screw fixation (a surgical procedure), was able to race successfully post-injury. This particular case prompted the researchers to consider whether surgical treatment may be a more advisable route for such injuries.

Implications of the Study

• The researchers examined these cases to develop better techniques and approaches to diagnosing this strong of fracture.
• Additionally, they used follow-up data to evaluate conventional non-surgical methods, highlighting the need for improved treatments or to consider surgical approaches for better outcomes.
