1- Coronary grooving
Coronary grooving involves removing a groove of hoof wall just distal to the coronary band. It is thought to encourage dorsal hoof wall growth and improve alignment of the wall.
2- Deep digital flexor tenotomy
The approach to therapy has been to cut this tendon, either in the cannon region (mid-metacarpus) or in the pastern region. Over a time period of 6 weeks, tenotomy is thought to allow P3 to realign with the ground surface.
