摘要: Doing an arthrogram is one thing, but interpreting the findings another, and operator must perform many hip arthrograms before he in a position to interpret with confidence. We owe our present knowledge of interpretation pioneer work Severin. This based on his ‘cinnoidin arthrograms’ where injected hips stillborn children at full term mixture cinnabar celloidin. When ‘cinnoidin’ had solidified, arthrographic casts were checked by radiography they subsequently dissected compared radiographic appearances.
