pseudarthrosis

 [so̳″ahr-thro´sis]
a pathologic entity characterized by deossification of a weight-bearing long bone, followed by bending and pathologic fracture, with inability to form normal callus; this leads to existence of the “false joint” that gives the condition its name.

pseu·dar·thro·sis

(sū'dar-thrō'sis),
A new, false joint arising at the site of an ununited fracture.
[pseud- + G. arthrōsis, a joint]

pseudarthrosis

/pseud·ar·thro·sis/ (soo″dahr-thro´sis) a pathologic condition in which failure of callus formation following pathologic fracture through an area of deossification in a weight-bearing long bone results in formation of a false joint.

pseu·dar·thro·sis

(sūd'ahr-thrō'sis)
A new, false joint arising at the site of an ununited fracture.
Synonym(s): false joint, pseudoarthrosis.

pseudarthrosis

formation of a false joint due to persistent non-union of fracture; characteristic of von Recklinghausen's disease (intraosseous neurofibroma causes a non-healing fracture)

pseu·dar·thro·sis
