PECTORALIS MINOR
PECTORALIS MINOR
IT ONLY WORK ON SCAPULA AND PLAY VITAL ROLE IN SHOULDER BIO MECHANISMS.
IT STABLE SCAPULA WITH OTHER MUSCLES LIKE SERRATES ANTERIOR .
2 LEVATER
SCAPULAE
FUNCTION OF PECTORALIS MINOR
- DEPRESS SCAPULA
- ABDUCT SCAPULA
- DOWNWARD ROTATE SCAPULA
IT IS SMALL MUSCLE UNDER THE COVER OF BIG PECTORALIS MAJOR MUSCLE NOT EASLIY PALPABLE.
SHORTENING OF THIS MUSCLE CHANGE THE INSTANT CENTRE OF ROTATION(ICR) OF HUMERUS HEAD IN
GLENOID CAVITY. DISTURBANCE OF ICR PRODUCE MAL-ALIGMENT OF SYSTEM AND IT CHANGE SPACE
DYNANIISM OF SUB-ACONIAL SPACE.IN MAL-ALIGNED POSITION EVEN NORMAL MOVEMENT PRODUCE
MICRO-TRAUMA TO SHOULDER TENDONS AND SUN ACOMIAN BURSA. LONG TIME STATUS PRODUCE MUSCLE LENGTH DISCREPENCY IN SYSTEM. SYSTEM BECOME WEAK DUE TO LONG LENGTH MUSCLES
AS WELL AS SHORT LENGTH MUSCLE.
FIRST SYMPTOM CAUSE AS A PAIN IN SOME RANGE DUE TO IMPENGEMENT.IF THIS STORY GOES ON DIFFERENT DIAGNOSIS APPEAR ACCORDING TO STATUS OF TISSUE LIKE
TENDINITIS,BURSLIS,CAPSULITIS LABRUM TEAR ETC.
A SMALL CULPRIT SETTING VERY SAFETY WITHOUT RECOGNITION.
