Try searching for DISH: Diffuse Idiopathic Skeletal Hyperostosis (no wonder they called it Forestiers!)

https://www.mayoclinic.org/diseases-conditions/diffuse-idiopathic-skeletal-hyperostosis/symptoms-causes/syc-20371661

https://rarediseases.info.nih.gov/diseases/6460/diffuse-idiopathic-skeletal-hyperostosis

are two fairly understandable articles about it.
