Osteosclerosis
(重定向自Osteosclerosis congenita)
Osteosclerosis is a type of osteopetrosis that involves abnormal hardening of bone and an elevation in bone density. It can be a pathology, normally detected on a radiograph as an area of increased opacity; that is, where more mineral is present in the bone to absorb or deflect the X-ray beam. Localized osteosclerosis can be caused by injuries that compress the bone, by osteoarthritis, and osteoma.
