Osteoclasis
Definition:
(n.) The operation of breaking a bone in order to correct deformity.
Example Sentences:
(1) The modern corticotomy has evolved from the initial open osteotomies, which eventually proved to be traumatic to bone's osteogenic elements, and closed bone osteoclasis, which proved time consuming and difficult to control.
(2) The question of osteoblastic osteoclasis falls into this category.
(3) The distractions were performed after both open osteotomy and closed osteoclasis.
(4) The correction of angular deformities of long bones by incomplete osteotomy, followed three weeks later by manual osteoclasis, overcomes the problem of secondary displacement sometimes seen after correction by complete osteotomy and makes internal fixation unnecessary.
(5) Bone loss may be the direct result of mechanical injury, increased osteoclasis, or direct lysis of bone by various enzymes released by the interface membrane.
(6) Eight years ago, axial correction of deformities of the femora and tibiae by manual osteoclasis was carried out in a 7 year old girl in whom osteogenesis imperfecta had produced severe bowing of the long bones of the legs.
(7) In one case, a 15 degree internal rotation deformity was corrected after 5 weeks by osteoclasis and fresh elastic nailing which also healed.

Urinary calcium excretion was greater in sham-operated rats given vitamin D than in uremic rats.
