Harvey, a 7 year active male labrador, presented lame with degenerative joint disease (DJD) affecting digits 2, 3 and 5 of the left forelimb. The metacaro-phalangeal joint of the 3rd digit seemed the most painful on palpation and¬† this joint was the one of the three that was involving a principal weight bearing digit. The middle two digits are the main weight bearing ones. This joint was excised with an oscillating saw. The gap was left to fill with flexible fibrous tissue to forma¬† a pseudarthrosis (a “false joint”).

Lameness seemed resolved a few weeks post-op, and he is buidling back to normal activity over a few weeks.
