“Some reports detail the use of thyroid supplementation as a therapeutic regimen for foot necrosis syndrome; however, thyroid levels were not determined in the treated birds, and the indiscriminate administration of thyroxin can cause fatal toxicity.”
Apparently, it is also possible for Bumblefoot to spread into the tendons and boney structures of the feet. This can cause loss of use of the foot and movement.
