Background Accurate assessment of the critical shoulder angle (CSA) is important in clinical evaluation of degenerative rotator cuff tears. Intra- and inter-observer reliability was high (ICC≥0.81) but decreased with increasing viewing angle. Views beyond 5° anteversion 8 retroversion 15 flexion and 26° extension resulted in >2° deviation Flavopiridol HCl of the CSA compared to true… Continue reading Background Accurate assessment of the critical shoulder angle (CSA) is important
