Endoscopic examination of the carpal flexor tendon sheath in horses.

The research aims to develop a safe procedure for examining the carpal flexor tendon sheath in horses through endoscopy. The researchers evaluated the safest approach to the sheath by considering anatomical structures, such as major arteries, veins, and nerves.

Initial Anatomical Study

• The researchers examined the limbs of 15 different horses to understand the typical structure of the carpal sheath and surrounding areas.
• The purpose of understanding the normal anatomy was to identify the safest entry points for the endoscopic procedure.
• Determining the sites of major arteries, veins and nerves within and around the sheath was crucial to prevent possible complications during the procedure.

Assessment of Portals

• A number of potential entry points – or ‘portals’ – were evaluated for the procedure, based on the earlier anatomical study.
• The research aimed not just to find a safe approach but also one that would give an adequate view of most parts of the carpal sheath.
• With this goal in mind, the researchers found that a distal lateral approach was both the safest and most beneficial for visualization.

Procedure and Results

• After determining the best portal, the research team then established a detailed surgical technique tailored to the approach.
• Fundamental to this method was ensuring the insertion of the arthroscope without causing trauma to any critical anatomical structures.
• The successful results of the research were described in detail, presenting an established and safe way to perform an endoscopic examination of the carpal flexor tendon sheath in horses.
