  Axial osteosclerosis - WrongDiagnosis.com
Axial osteosclerosis: A rare bone abnormality involving patches of increased bone density which tend to occur in the spine, pelvis and the ball part of the hip joint.
Axial osteosclerosis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
This means that Axial osteosclerosis, or a subtype of Axial osteosclerosis, affects less than 200,000 people in the US population.

It is important to realize that the degree of osteolysis versus the degree of osteosclerosis in a bone lesion has nothing to do with categorizing the lesion as aggressive or nonaggressive.
Primary tumors of the axial skeleton may be purely osteolytic, osteolytic and osteoblastic, or purely osteoblastic.
The primary diagnostic considerations for aggressive lesions of the axial skeleton are neoplasia, infection, and trauma.

 What are the long-term effects of ingesting fluoride on our bones?
Osteosclerosis in workers exposed to fluoride (F) and aluminum (Al) (industrial fluorosis) led to the use of F as a treatment to increase bone mass in osteoporosis patients.
Because the influence of traces of Al on the effects of F on bone formation is heretofore unknown, we have investigated this issue both in vitro and in vivo.
Thus, osteosclerosis and osteoporosis demonstrated by X-ray should be considered as manifestation of bone fluorosis.

Symptoms are progressive with age, and correlated with osteosclerosis.

Whereas bone mass and architecture in all appendicular and most axial sites is normally controlled by loading history, the new bone formed as a result of artificially stimulated bone remodeling using fluoride is exclusively appositional, with no creation of new trabeculae (Balena, et al.
It has an "abnormal texture" that is less strong (Lips, 1998), and the loss in trabecular strength due to the adverse influence of fluoride treatment altering the normal control has been calculated (Carter and Beaupre, 1990).
These large crystals (calcium-fluoride) which are not present in either controls or osteoporotic bone before the fluoride treatment contribute to increased mineral density with no improvement in mechanical properties (ibid, 1994).

To help clarify the relevance of skeletal fluorosis studies to fluoride therapy, it is instructive to note the comment made by Riggs (1983) in his comprehensive review of fluoride as a treatment for osteoporosis.
When fluoride is used therapeutically, therefore, it is obvious that conditions must be carefully chosen so as to maximize the development of osteosclerosis and to minimize the undesirable manifestations of osteoporosis and osteomalacia." - Riggs BL.
