These are diseases affecting the skeleton, bone, cartilage, tendons and ligaments.
Some are more common in people over 50 years: it is osteoarthritis that affects the cartilage and osteoporosis, which weakens bones, increasing the risk of fractures.

These so-called degenerative diseases associated with aging.
Our skeletal structure is not an inert by millions of cells called osteoclasts break down bone, which was rebuilt by other cells, osteoblasts, thus ensuring a perpetual revision. In degenerative diseases, the cells responsible for synthesizing bone or cartilage anabolism have reduced the quantity of these tissues decreases.

These degenerative diseases are a source of pain and disability.
The diagnosis of osteoporosis is often made at the waning of a fracture whose consequences may be more or less serious. The major osteoporotic fractures are those of the hip, spine and wrist. They receive 40% of women and 16% of men over 50 years.
Osteoarthritis is also very common but not always painful. For example, in 75% of women 65 to 75 years are observed radiological osteoarthritis digital, and in 35% of them from osteoarthritis of the knees.

Diseases of the musculoskeletal system may also be inflammatory and reach people of all ages. The most common disease and rheumatoid arthritis that affects approximately 0.5% of the population (maximum frequency among women aged 30 to 50 years), but also other inflammatory diseases such as rheumatic pelvi-spondylitis.
