Club foot refers to a hoof that is more upright than normal. It is often associated with a concave front (dorsal) hoof wall, high (often contracted) heels, and widening of the white line from mechanical stretching of the hoof wall attachments (the laminae). Adult club foot requires a completely different approach to treatment than juvenile club foot.
In many cases, mild club foot is not associated with lameness or decreased performance. Many great performance horses have managed to perform well with a club foot. However, there is a greater likelihood of lameness occurring in club feet than in normal feet. There is increased sole bruising and other problems of abnormal weight bearing in horses with club foot. Radiographs may show chronic changes to the coffin bone from excessive concussion, and excessive pull from the deep flexor tendon.
In most cases of adult club foot, it is not possible to simply shorten the heel to create a normal conformation. The problem with club foot is abnormal forces generated in the hoof. The natural concussion dampening of the lower limb is lost.
A grading system is used to describe severity:
Grade 1 – Three degrees greater angle than the opposite, pronounced coronary band.
Grade 2 – Growth rings, broken forward.
Grade 3 – Dorsal hoof wall is obviously concave.
Grade 4 – Angle greater than 80 degrees will require surgical approach.

Prognosis & Relevant Factors
Prognosis is good in most cases, especially with check ligament surgery. Prognosis is better in young horses and in less severe cases. There are also many horses that perform fine with a club foot. Much depends on the other structural factors of the foot.
