This question was provided by Manson Publishing as part of the OVAL Project. See more Equine Orthopaedic and Rheumatological questions |
An eight-year-old Thoroughbred gelding presented with a right forelimb lameness, grade 2/5 at the trot, of eight weeks duration. The lameness was insidious in onset, did not improve with rest or exercise, and was the same on any surface.
| Question | Answer | Article | |
| What abnormal features of the right forelimb can be recognised in the image? | There is marked distension of the digital sheath on the palmar aspect of the fetlock. The distal end of the swelling has a notched appearance. The horse has a slightly broken back hoof–pastern axis and low heels.

But in view of the poor foot conformation, a foot problem should also be considered as the cause of the lameness, since these digital sheath swellings are not always painful. |

| What further tests would you perform to confirm your diagnosis? | Intrasynovial analgesia of the digital sheath will not always abolish the lameness, presumably because of adhesions or the mechanical influence of the constricted annular ligament.
