Osteoporosis [osteopenia, decreased bone mineral density (BMD)] is a complex multifactorial disease with slow asymptomatic progression until bone fractures develop.

Osteoporosis

Osteoporosis is a pathology associated with increased fragility of bones. In most cases, it occurs in women due to age-related changes and the onset of menopause. Bones lose their strength, become much weaker and, as a result, break easily.

Osteophytes of the knee joint

Osteophytes of the knee joint provoke severe pain in the knee, almost unresponsive to the use of painkillers. The formation of osteophytes is associated with pathological changes in bone tissue.

Osteomyelitis: treatment

In all patients with osteomyelitis, treatment is based on the principles of active surgical management of purulent wounds and combines conservative and surgical measures. The ideal treatment option is a comprehensive approach involving specialists in chemotherapy, traumatology, purulent surgery, plastic surgeons and, if necessary, other consulting physicians.

Osteomyelitis of the long tubular bones in children. Causes. Symptoms. Diagnosis. Treatment

Orthopedic consequences of acute hematogenous osteomyelitis of long tubular bones are disturbances of anatomical relationships in joints (decentration, subluxation, dislocation), deformation and shortening of limb segments, disruption of bone tissue integrity (pseudoarthrosis and defect) and disruption of joint function in the form of contractures or ankylosis.

Osteomyelitis of the jaw

Osteomyelitis of the jaw is an inflammation of the jaw bone tissue caused by an infection. A dangerous disease, fortunately quite rare.

Osteomyelitis

The term "osteomyelitis" was proposed to denote inflammation of the bone and bone marrow (from Greek "osteomyelitis" means inflammation of the bone marrow). Currently, this term is understood as an infectious and inflammatory lesion of bone tissue (osteitis), bone marrow (myelitis), periosteum (periostitis) and surrounding soft tissues.

Osteoma. Causes. Symptoms. Diagnosis. Treatment

Osteoma is a highly differentiated benign tumor consisting of structures of predominantly lamellar structure. According to various data, the frequency of osteomas among skeletal neoplasms is 1.9-8.0%. Osteoma is most often detected at the age of 10-25 years.

Osteoma of the nasal cavity. Causes. Symptoms. Diagnosis. Treatment

Osteoma of the nasal cavity is a benign tumor that develops from bone tissue. The occurrence of osteoma in the nasal cavity is a rare phenomenon, most often this tumor primarily develops in the frontal and maxillary sinuses, in the ethmoid bone, and from here, growing, penetrates into the nasal cavity.

Osteoma of the middle ear: causes, symptoms, diagnosis, treatment

Osteoma of the middle ear is a tumor disease of the middle ear, which usually occurs in the petromastoid region, the starting point being either one of the air cells or the cortex of one of the internal cavities of the temporal bone.

Osteoma

It is assumed that risk factors for this formation may include traumatic brain injuries (including birth injuries), metabolic pathologies (in particular, calcium), and autoimmune diseases (systemic collagenoses).

Osteoid osteoma. Causes. Symptoms. Diagnosis. Treatment

Osteoid osteoma is a benign tumor up to 1.5 cm in diameter with a characteristic clinical and radiological picture, consisting of osteoid and weakly calcified primitive bone beams located in vascularized osteogenic tissue.

Osteogenic sarcoma

Osteogenic sarcoma is a malignant bone tumor that develops as a result of malignant transformation of rapidly proliferating osteoblasts and consists of spindle-shaped cells that form malignant osteoid.

Osteodystrophy

Osteodystrophy is a general term that describes a variety of disorders and changes in bone structure and function.

Osteochondrosis

Osteochondrosis is a degenerative-dystrophic disease that includes a complex of changes in the intervertebral disc and surrounding tissues and is manifested by polymorphic neurological syndromes. Osteochondrosis is the cause of back pain in 80% of cases.

Osteochondropathy

This pathology has a dystrophic nature and is closely associated with genetic factors. According to the international classification of diseases ICD 10, it is included in group XIII Diseases of the musculoskeletal system and connective tissue (M00-M99).

Osteochondropathies of the bones

Osteochondropathies are a group of diseases of the bone and joint system. They are characterized by aseptic subchondral infarction of the marginal area of spongy bone tissue in areas with increased load.

Osteochondropathies in children

In children, this pathology is much more common than in adults. This is due to the active growth of their skeletal system. The main age group of patients is from 2 to 18 years.

Osteoblastoma. Causes. Symptoms. Diagnosis. Treatment

Osteoblastoma (synonyms: giant osteoid osteoma, osteogenic fibroma) is a benign bone-forming tumor, histologically identical to osteoid osteoma, but differing from it in its larger size, clinical picture and data from radiation research methods.

Osteoblastoclastoma

Cases of oncological diseases are constantly increasing in the world. Among the lesions of the skeletal system, osteoblastoclastoma is the most frequent - a benign tumor process prone to malignancy, capable of damaging a wide variety of skeletal bones.
