When and how to use splints and casts in horses

This session explores the principles and clinical application of external coaptation in horses, highlighting the role of bandaging, splinting, and casting in the management of wounds, orthopaedic injuries, and post-operative care. Emphasis is placed on the biomechanical and anatomical principles that underpin effective external support, thereby demonstrating how appropriate material selection, pressure distribution, and application technique influence treatment success and patient welfare.

A range of bandaging techniques is considered, including routine wound dressings, Robert Jones bandages, and specialised configurations for challenging anatomical regions. The indications for splint use are discussed with the principles of fracture immobilisation, illustrating how splints complement bandages to provide rigid temporary support, thereby minimising further tissue damage, and facilitating safe patient transport.

Casting as a more rigid method of external coaptation is also discussed, comparing available cast types and materials whilst considering the factors that determine cast strength, stability, and suitability for different clinical scenarios. Practical aspects of cast application, including padding, limb positioning, and mechanical loading, are discussed in relation to optimising outcomes and reducing complications.

Throughout, attention is given to the potential risks associated with external coaptation, including pressure injuries and mechanical cast failure, emphasising the importance of meticulous technique, careful case selection, and ongoing monitoring. By integration of scientific principles with practical decision-making, this session provides a comprehensive overview of external coaptation techniques and their application in equine cases.

After attending this session, delegates will be able to:

• Apply evidence‑based principles of equine bandaging and casting, including layered construction, pressure distribution, and limb positioning, to optimise outcomes.
• Select and create appropriate bandage, splint, and cast configurations based on injury type, anatomical location, and biomechanical demands.
• Identify anatomical risk areas for pressure injury and implement targeted padding and support strategies to minimise complications.
• Recognise common complications associated with bandaging and casting and implement effective monitoring and aftercare to ensure safe stabilisation and healing.
