Approach Considerations

Generally, laboratory studies are not necessary. Genetic testing is indicated in bilateral cases in which a syndrome is suspected. Imaging studies may be helpful (see below). Histologic findings consist of synovial-lined pseudoarthrosis. [12]


Imaging Studies

On plain radiography, anterior, posterior, and apical lordotic views usually are sufficient. [16] Pseudoarthrosis of the midclavicle on the right is easily visualized and has a characteristic pattern, with anterior and superior tilting of the sternal half and a smaller acromial portion.

Magnetic resonance imaging (MRI) may be used to determine the extent of the fibrous union, the location of the great vessels, and the space available within the thoracic outlet. MRI is rarely indicated in this setting.
