Shoulder Clunking - what's the cause?

[linbin]

hi guys
i would like to add something more.as everybody knows shoulder,especially the glenohumeral joint depends on muscles more for stability.during movements,dynamic stability is mainly provided by rotator cuff muscles.concavity compression action my rotator cuff,help to maintain the integrity of the joint .so that other superficial muscles can act.when rotator cull is functioning properly it reduces translation to a minimum,bcos of its force couple action with deltoid in the vertical direction and force couple between subscapularis anteriorly and infraspinatus and teres minor posteriorly in transverse direction.so rotator malfunctioning leads to abnormal translation -clunking-ligament,capsular stress and lesions.so our management should give primary importance to causes of rotator malfunctioning and strengthening of rotator cuff muscles.
