It can also occur in a much more insidious manner when
the wrist joint, over a prolonged period of time, degenerates
due to the presence of severe arthritis.
This was the case with Zedby an elderly collie who was
referred to me from Ashby de la Zouche. He had been under
treatment from his own vet for his arthritis for a number
of years but recently his right carpus/wrist had collapsed
to the point where it could no longer support his body upright.
Once this occurs there is never any possibility of the
ligament repairing and regaining its original strength.
Ligaments have a poor blood supply and, due to the presence
of random collagen formation, the resulting scar tissue
is unable to perform the original task. Attempting to splint
the leg always results in failure.
