Today’s case is an orthopedic one involving a 3 month old domestic short haired cat with acute onset of left forelimb lameness. Check it out, and post your interpretations in the comments section.
3 month old DSH cat
Teaching and learning about veterinary diagnostic imaging.
The humerus is caudal in relation to the most distal part of the humerus. In other words there seems to be a separation along the distal physis- Salter Harris type 1 with a dislocation?
I agree about a Salter-Harris, with cranial displacement of the distal fragment. What is unclear is if there is also a fracture of the medial condyle (SH type II or III). I can see a shadow in the ML view, cranial to the distal fragment, and I seem also to see a fracture line within the distal fragment (goes craniocaudally); plus the caudal cortex seems interrupted. On the craniocaudal view, the medial condyle is displaced/a fragment is detached?
CT would be useful.
Physeal fracture with involvement of both distal physis and epiphysis – Salter Harris type III.
I agree with of all You that there is a Salter Harris III fracture. There is a well seen fracture on the ap projection between medial and lateral condyle. There is also soft tissue swelling on the medial side of elbow joint.
