A METHOD OF DETERMINING THE DEGREE OF WRISTS DEVIATION AT THE RHEUMATOID ARTHRITIS

摘要

A method of determining the degree of the wrists deviation at the rheumatoid arthritis is performed during the X-ray projection of wrists in frontal view. The axial lines are drawn through the third metacarpal and wrist bones and the angle between them is measured. If the detected angle is 15-25°, the mild severity of ulnar deviation of wrist us diagnosticated. If the angle is 25-40 ° - the average degree of ulnar deviation of wrist is diagnosticated. If the angle exceeds 40 °, the hard degree of the ulnar deviation is diagnosticated.
