[Purpose] We examined scapular motion in abduction in the patients with throwing pain and analyzed the relationship between the dysfunction of scapular motion and the clinical findings.[Materials and methods] Twenty-six patients who have pain during throwing motion (22 male and 4 female, mean age ; 22 years old) were reviewed retrospectively. All patients underwent bilateral shoulder A-P X-rays at every 30 degree abducted position from 0 to 150 degree abduction. Scapulo-thoracic angle (STA) and abduction angle (ABD) were measured on the X-ray films, and scapular abduction ratio (ΔSAR=ΔSTA/ΔABD) was calculated. According to the result of ΔSAR, the patients classified into two groups, large ΔSAR group and small ΔSAR group, and the clinical findings related to small ΔSAR were analyzed.[Results] The ΔSAR was smaller in the throwing side at 60-90 degree abduction (p=0.04). Eleven of 26 were classified into large ΔSAR, and 15 were classified into small ΔSAR. The clinical finding related to small ΔSAR was painful arc sign (p=0.03), and the other findings (sulcus sign, impingement sign, lateral scapular slide, scapular assistance test, scapular wing, relocation test, clunk test, fulcrum test, Bennett lesion) were not related statistically.[Discussion and conclusion] The result that small ΔSAR in throwing side related to painful arc sign means a loss of scapular upward rotation could increase loads to cuff and deltoid muscle and induce pain in abduction and in throwing motion.
