Question of the Day

The duck has septic arthritis. There is diffuse soft tissue swelling of the left pelvic limb.

There also appears to be intracapsular soft tissue swelling of the left tibiotarsal joint causing the joint space to widen asymmetrically. An osseous fragment is noted at the medial aspect of the joint.

The articular margins of the tibiotarsus and the tarsometatarsus appear lytic and irregular.

Egg-binding signs are nonspecific but lameness is not a key finding typically. Sometimes the bird will adopt a penguin-like posture. Egg-binding is more often seen during the spring and summer.
