What is osteoclasia?

1. (osteoclasty) the deliberate breaking of a malformed or malunited bone, carried out by a surgeon to correct deformity.

Is osteolysis common?

Abstract. Osteolysis of the pelvis is a common and well-recognized complication associated with total hip arthroplasty.

Is osteolysis reversible?

Most reported cases of osteolysis have been described as showing progres- sive change at a variable rate. There has not been any previously documented case in which there has been reversal of osteolytic change.

What causes osteolysis?

Osteolysis often occurs in the proximity of a prosthesis that causes either an immunological response or changes in the bone’s structural load. Osteolysis may also be caused by pathologies like bone tumors, cysts, or chronic inflammation.

What hormone causes osteolysis?

The activation of the PTHR1 via PTH or PTHrP, also the action of TGFβ on its receptor TGFβR2, as well as the absence of strain and therefore the expression of sclerostin can induce the osteolytic state, while calcitonin acts inhibitory.

What is repaired in Tenomyoplasty?

[ten″o-mi´o-plas″te] plastic repair of a tendon and muscle, applied especially to an operation for inguinal hernia.

What is osteomalacia?

Jump to navigation Jump to search. Osteomalacia is the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium.

What is an osteoclast?

An osteoclast can also be an instrument used to fracture and reset bones (the origin is Greek osteon: bone and klastos: broken). To avoid confusion, the cell was originally termed osotoclast.

What is the medical term for osteopenia?

Osteopenia, from Greek ὀστέον ( ostéon ), “bone” and πενία ( penía ), “poverty”, is a condition of sub-normally mineralized bone, usually the result of a rate of bone lysis that exceeds the rate of bone matrix synthesis. See also osteoporosis . In June 1992, the World Health Organization defined osteopenia.

What is the role of osteoclasts in bone mineralization?

The osteoclasts pump hydrogen ions into subosteoclastic compartment and thus create an acidic microenvironment, which increases solubility of bone mineral, resulting in the release and re-entry of bone minerals into the cytoplasm of osteoclasts to be delivered to nearby capillaries.
