[Dynamic radiologic examination of the wrist].

Several possible lesions of ligaments may be diagnosed using dynamic radiographs in radial or ulnar deviation, with stressing in torsion, traction, or radial, ulnar, anterior or posterior displacement. The initial position is strictly defined in the front and sagittal planes. The shapes of the bones, their relationship and the joint lines are observed. The authors have made a complete study of the normal wrist and describe some pathological conditions including dislocations, disjunctions between the scaphoid and lunate, mid-carpal sprains and radio-carpal sprains. Descriptions are given as to how to obtain standard radiographs in a painful wrist. Five views are necessary, four in the frontal plane, (radial and ulnar angulation, radial and ulnar displacement) and one in the sagittal plane.
