Arthritis was induced in all groups through injection of a 3% monosodium urate (MSU) solution into the intertarsal
joint as subsequently described.
Formalin fixed intertarsal
joint was decalcified in EDTA solution, trimmed, processed, and stained with hematoxylin and eosin (H&E).
The animal had been transferred from another institution 4 weeks prior to presentation with a history of osteoarthritis at the left intertarsal
joint and an asymptomatic systolic heart murmur.
The left wing was dropped, and swelling of the left intertarsal
joint was noticed.
Key words: rupture, repair, intertarsal
joint, extracapsular, ligament, collateral, avian, Pekin duck, Anas platyrhynchos domesticus
The anatomy of the intertarsal
joint and its function in locomotion was studied by Schaller et al.
Bilateral swelling of the plantar regions and moderately swollen intertarsal
joints were visible in 1 bird, with purulent exudate indicating septic arthritis and pododermatitis.
Mild to moderate pododermatitis over the intertarsal
joints developed because of a shift in weight bearing after the loss of most digits.
Inflammation, dermal ulcers, and green epithelial discoloration was present on the ventral aspect of both swollen intertarsal
joints (Fig 1).
Physical examination findings were overall unchanged, with the exception of a mild bilateral pododermatitis and a 1-cm plantar lesion on the left intertarsal
Radiographs showed bilateral intertarsal
joint osteoarthritis and a healed ulnar fracture.
Abstract: A 1.5-year-old female Mississippi sandhill crane (Grus canadensis pulla) was presented and managed for a polyarthritis of the intertarsal
and tarsophalangeal articulations.
