Humero-ulnar synostosis

Description

A condition caused by failure of the arm bones to correctly develop during the antenatal period. This condition is characterised by direct fusion of the humerus and radial bones of the arm, and consequent inability to straighten the elbow joint. Confirmation is through observation of humero-ulnar fusion by imaging.
