Osteochondritis Dissecans
|
D010008 |
[A type of osteochondritis in which articular cartilage and associated bone becomes partially or totally detached to form joint loose bodies. Affects mainly the knee, ankle, and elbow joints.

|
Osteochondrodysplasias
|
D010009 |
[Abnormal development of cartilage and bone.

|
Osteochondroma
|
D015831 |
[A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is the most common of benign bone tumors.

Osteochondromatosis
|
D018216 |
[A condition marked by the presence of multiple osteochondromas. (Dorland, 27th ed)
] |
|
Osteochondrosis
|
D055034 |
[Any of a group of bone disorders involving one or more ossification centers (EPIPHYSES). It is characterized by degeneration or NECROSIS followed by revascularization and reossification. Osteochondrosis often occurs in children causing varying degrees of discomfort or pain. There are many eponymic types for specific affected areas, such as tarsal navicular (Kohler disease) and tibial tuberosity (Osgood-Schlatter disease).

|
Osteoclasts
|
D010010 |
[A large multinuclear cell associated with the BONE RESORPTION. An odontoclast, also called cementoclast, is cytomorphologically the same as an osteoclast and is involved in CEMENTUM resorption.
] |
|
Osteocytes
|
D010011 |
[Mature osteoblasts that have become embedded in the BONE MATRIX. They occupy a small cavity, called lacuna, in the matrix and are connected to adjacent osteocytes via protoplasmic projections called canaliculi.
] |
|
Osteogenesis
|
D010012 |
[The process of bone formation. Histogenesis of bone including ossification.
] |
|
Osteogenesis Imperfecta
|
D010013 |
[COLLAGEN DISEASES characterized by brittle, osteoporotic, and easily fractured bones. It may also present with blue sclerae, loose joints, and imperfect dentin formation. Most types are autosomal dominant and are associated with mutations in COLLAGEN TYPE I.

|
Osteogenesis, Distraction
|
D019857 |
[Bone lengthening by gradual mechanical distraction. An external fixation device produces the distraction across the bone plate. The technique was originally applied to long bones but in recent years the method has been adapted for use with mandibular implants in maxillofacial surgery.

|
Osteology
|
D059166 |
[The branch of anatomy that concerns the structure and function of bones.
] |
|
Osteolysis
|
D010014 |
[Dissolution of bone that particularly involves the removal or loss of calcium.
] |
|
Osteolysis, Essential
|
D010015 |
[Syndromes of bone destruction where the cause is not obvious such as neoplasia, infection, or trauma. The destruction follows various patterns: massive (Gorham disease), multicentric (HAJDU-CHENEY SYNDROME), or carpal/tarsal.
] |
|
Osteoma
|
D010016 |
[A benign tumor composed of bone tissue or a hard tumor of bonelike structure developing on a bone (homoplastic osteoma) or on other structures (heteroplastic osteoma). (From Dorland, 27th ed)
] |
|
Osteoma, Osteoid
|
D010017 |
[A benign osteoblastic tumor with central vascularized nidus surrounded by normal reactive bone. It occurs especially in second decade of life most commonly in the femoral neck but can occur in any bone and any site within a bone.
] |
|
Osteomalacia
|
D010018 |
[Disorder caused by an interruption of the mineralization of organic bone matrix leading to bone softening, bone pain, and weakness. It is the adult form of rickets resulting from disruption of VITAMIN D; PHOSPHORUS; or CALCIUM homeostasis.
] |
|
Osteomyelitis
|
D010019 |
[INFLAMMATION of the bone as a result of infection. It may be caused by a variety of infectious agents, especially pyogenic (PUS - producing) BACTERIA.
] |
|
Osteonecrosis
|
D010020 |
[Osteonecrosis of the lunate.
, Death of a bone or part of a bone, either atraumatic or posttraumatic.
] |
|
Osteonectin
|
D015676 |
[Non-collagenous, calcium-binding glycoprotein of developing bone. It links collagen to mineral in the bone matrix. In the synonym SPARC glycoprotein, the acronym stands for Secreted Protein, Acidic and Rich in Cysteine.

|
Osteopathic Medicine
|
D010021 |
[A medical discipline that is based on the philosophy that all body systems are interrelated and dependent upon one another for good health. This philosophy, developed in 1874 by Dr. Andrew Taylor Still, recognizes the concept of "wellness" and the importance of treating illness within the context of the whole body. Special attention is placed on the MUSCULOSKELETAL SYSTEM.
