Medical Dictionary Definitions A-Z List

Medical Dictionary Definitions A - Z - «O»:

  1. Osteoclasia Osteoclasia
    Osteoclasia: Destruction and reabsorption of bone tissue, as occurs when broken bones heal....
  2. Osteoclasis Osteoclasis
    Osteoclasis: The surgical destruction of bone tissue. Osteoclasis is performed to reconstruct a bone that is malformed, often a broken bone that healed improperly. The bone may be broken and then reshaped with the aid of metal pins, casting, and bracing....
  3. Osteoclast Osteoclast
    Osteoclast: A cell that nibbles at and breaks down bone and is responsible for bone resorption. Osteoclasts are large multinucleate cells (cells with more than one nucleus) that differentiate from another type of cell called a macrophage. In normal bone, bone formation and bone resorption are close...
  4. Osteoclastoma Osteoclastoma
    Osteoclastoma: A type of bone tumor characterized by massive destruction of bone near the end (epiphysis) of a long bone. The site most commonly struck by this tumor is the knee -- the far end of the femur and the near end of the tibia. The tumor is often coated by new bony growth. It causes pain an...
  5. Osteocyte Osteocyte
    Osteocyte: A bone cell....
  6. Osteodystrophy Osteodystrophy
    Osteodystrophy: A bone disorder that adversely affects bone growth. See also renal osteodystrophy....
  7. Osteodystrophy, renal Osteodystrophy, renal
    Osteodystrophy, renal: A bone growth disorder caused by chronic kidney failure (renal disease). Also known as renal osteodystrophy....
  8. Osteogenesis Osteogenesis
    Osteogenesis: The production of bone....
  9. Osteogenesis imperfecta Osteogenesis imperfecta
    Osteogenesis imperfecta: Brittle bone disease. Osteogenesis imperfecta (OI) is not one but a group of genetic diseases, all of which affect collagen in connective tissue in the body and all of which result in fragile bones. The best known types are types I and II....
  10. Osteogenesis imperfecta congenita Osteogenesis imperfecta congenita
    Osteogenesis imperfecta congenita: See: Osteogenesis imperfecta type II. ...
  11. Osteogenesis imperfecta tarda Osteogenesis imperfecta tarda
    Osteogenesis imperfecta tarda: See: Osteogenesis imperfecta type I. ...
  12. Osteogenesis imperfecta type 1 Osteogenesis imperfecta type 1
    Osteogenesis imperfecta type 1: An inherited connective tissue disorder featuring bone fragility and blue sclerae (blue whites of the eyes). This is the classic form of "brittle bone disease." Osteogenesis imperfecta type 1 is an autosomal dominant trait. (One copy of the mutant gene is enoug...
  13. Osteogenesis imperfecta type 2 Osteogenesis imperfecta type 2
    Osteogenesis imperfecta type 2: An inherited connective tissue disorder with extremely severe bone fragility. This is the lethal form of "brittle bone disease." Osteogenesis imperfecta type 2 is a recessive trait with males and females affected. Two copies of the mutant gene are needed to cause t...
  14. Osteogenesis imperfecta with blue sclerae Osteogenesis imperfecta with blue sclerae
    Osteogenesis imperfecta with blue sclerae: See: Osteogenesis imperfecta type I. ...
  15. Osteogenesis, electrically stimulated Osteogenesis, electrically stimulated
    Osteogenesis, electrically stimulated: Bone growth caused by implanting electrodes in an area of bone and sending electrical current to them. This procedure may be used to jump-start the healing process when a bone has been broken....
