Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders.{{cite journal | author = EL-Sobky TA, Elsobky E, Sadek I, Elsayed SM, Khattab MF | year = 2016 | title = A case of infantile osteopetrosis: The radioclinical features with literature update |url=| journal = Bone Rep | volume = 4 | pages = 11–16 | doi = 10.1016/j.bonr.2015.11.002 | pmid = 28326337 | pmc = 4926827 }} It can manifest in localized or generalized osteosclerosis. Localized osteosclerosis can be caused by Legg–Calvé–Perthes disease, sickle-cell disease and osteoarthritis among others. Osteosclerosis can be classified in accordance with the causative factor into acquired and hereditary.

Diagnosis
Osteosclerosis can be detected with a simple radiography. There are white portions of the bone which appear due to the increased number of bone trabeculae.{{citation needed|date=October 2020}}
Animals
In the animal kingdom, there also exists a non-pathological form of osteosclerosis, resulting in unusually solid bone structure with little to no marrow. It is often seen in aquatic vertebrates, especially those living in shallow waters,Houssaye, A. (2009). "Pachyostosis" in aquatic amniotes: a review. Integrative Zoology 4(4): 325-340. providing ballast as an adaptation for an aquatic lifestyle. It makes bones heavier, but also more fragile. In those animal groups, osteosclerosis often occurs together with bone thickening (pachyostosis). This joint occurrence is called pachyosteosclerosis.{{cite journal | last1=Crowell | first1=Madelyn Galimore | last2=Rahmat | first2=Sulman | last3=Koretsky | first3=Irina | title=Correlation of Bone Density in Semi-Aquatic and Aquatic Animals with Ecological and Dietary Specializations | journal=The FASEB Journal | publisher=Wiley | volume=34 | issue=S1 | year=2020 | issn=0892-6638 | doi=10.1096/fasebj.2020.34.s1.01860 | pages=1| s2cid=218789355 | doi-access=free }}
