EQUINE | Equine Disease Update opinion rather than fact, research and sound long-term clinical impressions. Veterinarians and farriers need to work together to develop good basic farriery using anat- omy, foot function and an emphasis on biomechanical principles. Dr O’Grady has suggested that the ambigu- ous term ‘hoof balance’ should be replaced with stan- dardised, repeatable guidelines for trimming the foot. These guidelines include the hoof-pastern axis, the cen- tre of rotation and the heels of the hoof capsule trimmed to the base of the frog when trimming the foot. The use of shoes should be simplified, basing their use and ap- plication on strict biomechanical principles appropriate to the use and requirements of each horse. Clinical highlights: The farrier and veterinarian should form a close partnership allowing them to use sound biomechanical principles to trim and shoe both the nor- mal and abnormal hoof and maximise the welfare and benefit to the horse. Authorship This was a clinical review article of the 50th South African Equine Veterinary Association Congress. The authors divided the guest lectures equally between them to write up reviews on them. They also both re- viewed each other’s work for grammatical and spelling errors. Both authors have reviewed the final draft and have accepted it. S. M. Miller and K. E.
