Adult (n = 15) and juvenile (n = 18) falcons were experimentally inoculated with different dosages of the same strain of Aspergillus fumigatus and an additional 3 falcons from each age group were used as uninfected control animals.

Avascular necrosis (AVN) of the femoral head is a pathologic process that results from interruption of blood supply to the bone. AVN of the hip is poorly understood, but this process is the final common pathway of traumatic or nontraumatic factors that compromise the already precarious circulation of the femoral head. Femoral head ischemia results in the death of marrow and osteocytes and usually results in the collapse of the necrotic segment.
