Old norse stories tell of a famous viking named egil, who lived around 900 ad. his skull was greatly enlarged and misshapen, and the cranial bones were thickened (6 cm, more than 2 inches, thick). he had headaches from the pressure exerted by enlarged vertebrae on his spinal cord. so much blood was diverted to his bones to support their extensive remodeling that his fingers and toes always felt cold and his heart was damaged through overexertion. what bone disorder did egil probably have?

Paget's disease

Explanation:

It is a chronic condition of bones understood as a disorder of the normal bone remodeling and recycling processes.

Paget's disease results in irregular thickening of bone tissue due to new bone tissue gradually replaces old bone tissue.

Paget's disease commonly affects pelvis, skull spine and legs, causing pain and deformity in them.

It also produces broken bones, hearing loss pinched nerves in the spine due to this disease increases with age.

The bone disorder that Egil could've probably suffered from is called Paget's disease.

Explanation:

Paget's disease is an infrequent chronical bone disorder, in which bone repair occurs rapidly and isolated. This condition may cause a variety of symptons as aching in the spine, head and arms, hips and thighs; leading to health problems as arthritis, heart disease, nervous system issues, hearing loss, vision problems, lose of teeth and a type of cancer named Piaget's sarcoma.

A possible cause for this disorder is a virus called measles virus that occurs during childhood that leads to bone formation alterations.
