In 2013, Cedar Lawns Abby, lovingly known as Abby, was diagnosed with chronic subluxation of the coffin bone in her right front hoof and severe ringbone in her left front hoof (see photos A and B). A previous farrier had been using reversed metal horse shoes in an attempt to give her some relief (see photos C1-C3). Dr. Harrison had been injecting the right coffin joint in an attempt to give some stability to the foot and fuse the joint.
