Pseudarthrosis

false joint, persistent pathological mobility throughout a bone (generally a long bone).

Pseudarthrosis is classified as either congenital or acquired. The cause of congenital pseudarthrosis is an aberration in the bone’s intrauterine development. Tibial pseudarthrosis (usually in the lower third of both bones) is among the most frequent of the congenital group. Acquired pseudarthrosis develops after injury to a bone (fracture, osteotomy), osteomyelitis, or impairment of a bone’s regenerative function (rickets, osteomalacia, scurvy). Treatment is surgical.
