This hoof had a fissure in the quarter for 8 years which developed into a deep crack through the mechanics in the toe and the heel which were working against each other.
This hoof condition caused the horse to go lame.
Through hoof orthopedic work, treating the forces causing the cracks and thus returning the hoof into a physiologically sound shape, the crack will grow out, unless the coronary band has already been damaged.
The lameness stopped after the third trimming.
Shown here is the condition of the hoof before treatment from 3 different angles and the preliminary result after 16 months. The crack is already closed and the horn of the wall can now grow out soundly with continuing hoof orthopedic trimming.
