RTC pathology
RTC tear
Impingement
AC jt cluster
Supraspinatus tendinopathy
Infraspinatus tear
2. ER lag sign
Subscap tear
Anterior instability
IRRST:
if IR MMT < ER, think intra articular issue ( labrum, anterior impingement, bankart)
if ER < IR, think RTC pathology (impingement or tear)
if ER=IR, think EXTRA articular (no issue with RTC) - AC jt, LHB etc
SLAP
2. Passive distraction and active compression
Postero-inferior labral tear
2/2 99%
0/2- 1%
