The first is a DDF tenotomyperformed at mid cannon, the second being performed mid pastern. The two techniques can both beperformed standing or under general anesthesia. Generally the first DDF tenotomy performed on a horse is executed at the mid cannon level. Performing the first DDF tenotomy at mid cannon leaves room at the lower cannon area for a second tenotomy and leaves the mid pastern area available as well. Generally much greater release of the DDFT is achieved at the mid pastern level.
