At osteoporosis the density and durability of bone decreases. This metabolic disorder accompanies many diseases. The key moment in development of pathology – decrease of calcium content in bone tissue. As a result durability of bones decreases, more often there are fractures, even at small mechanical influences. Generally elderly people are affected with osteoporosis.

First the osteoporosis externally isn’t shown. More often deficiency of calcium arises in the bones carrying large load – backbone, femoral, humeral.

Pain is the first clinical sign of backbone osteoporosis. First it is aching, local, doesn’t extend anywhere. Later on with degeneration of vertebrae pain changes gaining radicular character.

Because of vertebrae changes human height sometimes decreases by some centimeters. There are deformations of backbone, physiological flexures, especially thoracic kyphosis, are enlarged, there is an expressed slouch or hump. Scoliosis (lateral curvatures) are frequent. Fractures arise at insignificant influences – jerks, kicks, falling.

Signs of calcium deficiency become perceptible: cramp in sural muscles at night, unstable arterial pressure, digestive disturbances, endocrine disorders (diabetes mellitus), decrease of immunity, memory impairment. There are cosmetic defects: deformation of teeth, fragility of fingernails and hair, decrease of skin elasticity.

Treatment of osteoporosis is based on restore of calcium deficiency. Classical calcium salts are not very effective, but there are a lot of new effective medicines.
