Nearthrosis (pseudoarthrosis) - mobility during a bone as a result of a failure of union of fracture.

Etiology. An infection, frustration of blood supply of a bone, the mobility of fragments more often arising at a premature cast removal. As a result of it in a zone of fracture instead of osteal the connecting and cartilaginous tissue develops. Occasionally nearthroses happen congenital (disturbance of fetal development of a bone).

Signs, current. Disturbance of basic function of a leg or a depression of function of an arm are quite often defined a curvature of an extremity at a level of a nearthrosis, a pain in it. At so-called hard nearthroses (massive development of cicatrix between fragments, the small cleft between them) pains and disturbances of function can not be.
