We have previously studied rheumatoid shoulders by plain radiography and arthrography.
But we believe evaluating rheumatoid shoulders with limited abduction by such methods is insufficient. So this time, we used dynamic radiographies and evaluated 41 rheumatoid shoulders.
Scapular plane radiographies were taken of the arm by the side to maximum elevation at thirty-degree-intervals analyze the motion, and were evaluated by the rhythm of the Gleno-Humeral (G-H) motion and the Scapulo-Thoratic (S-T) motion.
We also compared the dynamic analysis to plain radiographie s to clarify the influence of joint destruction to abduction motion. There are two motion patterns in rheumatoid shoulders with limited abduction. One is the normal rhythm pattern which reserves normal rhythm and has a mild joint destruction, and the other is the S-T dominant pattern which dose not keep normal rhythm and has severe joint destructions.
