Rotator Cuff Tears
The
rotator cuff
muscles functions to contain the humeral head as we move our shoulder.
The four muscles that make up the rotator cuff are the supraspinatus,
infraspinatus, teres minor, and subscapularis. These muscles originate
from the scapula and converge to form a cuff to tendon that inserts
into the humeral head. It is
the convergence of four muscles
about the shoulder
that forms the rotator cuff. Together with the deltoid muscle, the
rotator cuff allows us to move our arm away from our body.
When the rotator cuff tears, the person can develop weakness and pain
in the shoulder that can lead to stiffness. As we age, it is
common to develop tears of the rotator cuff tendon.
Not all rotator cuff tears require
surgical intervention. For years the standard technique to repairs
these tendons required large incisions about the shoulder and hospitals
stays of several days. Today, many orthopedists repair these tendons
with arthroscopic techniques as a day surgery. When rotator cuff tears
have been present for a long time, it is common for the tendon to
retract and atrophy, which could make it non repairable.
