Noma—a gangrenous disease still widespread among malnourished children living on the borders of the Sahara desert—can cause ankylosis of the maxilla and mandible, impairing the ability to speak and eat. Fibrodysplasia Ossificans Progressiva is a rare bone disease in which muscle, tendons and ligaments turn to bone. This leads to progressive ankylosis of almost all joints. Society and culture
In 2014, Liliana Cernecca, a six-year-old girl at the time, was only able to open her mouth a couple millimeters after one of her jaw joints fused. She underwent surgery to correct her jaw ankylosis during which her jaw was operated on and unlocked. Fossil record
Evidence for ankylosis found in the fossil record is studied by paleopathologists, specialists in ancient disease and injury. Ankylosis has been reported in dinosaur fossils from several species, including Allosaurus fragilis, Becklespinax altispinax, Poekilopleuron bucklandii, and Tyrannosaurus rex (including the Stan specimen).
