Osteopenia, known as "low bone mass" or "low bone density", is a condition in which bone mineral density is low. [1] Because their bones are weaker, people with osteopenia may have a higher risk of fractures, and some people may go on to develop osteoporosis. [2] In 2010, 43 million older adults in the US had osteopenia. [3]
Hip fractures are responsible for the most serious consequences of osteoporosis. In the United States, more than 250,000 hip fractures annually are attributable to osteoporosis. [190] A 50-year-old white woman is estimated to have a 17.5% lifetime risk of fracture of the proximal femur. The incidence of hip fractures increases each decade from ...
Gorham's disease (pronounced GOR-amz), also known as Gorham vanishing bone disease and phantom bone disease, [1] is a very rare skeletal condition of unknown cause.It is characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis.
Stress shielding is the reduction in bone density as a result of removal of typical stress from the bone by an implant (for instance, the femoral component of a hip prosthesis). [1] This is because by Wolff's law, [2] bone in a healthy person or animal remodels in response to the loads it is placed under. It is possible to mention the elastic ...

Metabolic bone disease is an abnormality of bones caused by a broad spectrum of disorders. Most commonly these disorders are caused by deficiencies of minerals such as calcium, phosphorus, magnesium or vitamin D leading to dramatic clinical disorders that are commonly reversible once the underlying defect has been treated.
Senile osteoporosis has been recently recognized as a geriatric syndrome with a particular pathophysiology. There are different classification of osteoporosis: primary, in which bone loss is a result of aging and secondary, in which bone loss occurs from various clinical and lifestyle factors. [1]
In 2010, over 258,000 people aged 65 and older were admitted to the hospital for hip fractures. [6] Incidence of hip fractures is expected to rise by 12% in America, with a projected 289,000 admissions in the year 2030. [7] Other sources estimate up to 1.5 million Americans will have an osteoporotic-related fracture each year. [8]
