Subscapularis muscle
function
The subscapularis muscle arises on the inside of the shoulder blade, the Subscapular fossa.
He sits on the little hump (Lesser tuberosity) of the humerus (Humerus) and on the underlying bony structure (Crista tuberculis minoris) on.
The main task of the muscle is the internal rotation of the upper arm in the shoulder. In addition, the muscle brings the upper arm closer to the body (adduction) and can also lead it away from the body (abduction). Some muscle fibers are fused with the capsule of the shoulder joint and thereby tighten and stabilize the joint capsule.
Diseases
Since the terminal tendon of the subscapularis muscle is very wide, it offers one important protection against anterior shoulder dislocation.
Is the subscapularis muscle under a Rotator cuff rupture injured, the usual symptoms of a rotator cuff tear may appear first. These include strong pain and in the case of the subscapularis muscle, one clearly restricted Internal rotation of the arm.
However, it is also possible that in the course of the accident, the Shoulder simultaneously "dislocated" (luxated) becomes. A counter impact on a raised (abducted) and externally rotated one is typical poor, for example when playing handball. In such a case the patient has strongest pain and holds the arm slightly away from the body and supports it on the side. The mobility in the shoulder is blocked and the normal contour of the shoulder is missing.
In the X-ray examination The humerus head can no longer be seen in the joint socket in two planes, in one Magnetic resonance imaging (CT) or Magnetic resonance imaging of the shoulder the tear of the subscapularis muscle is noticeable. The function of the subscapularis muscle can also be caused by paralysis of the nerve supplying it (Subscapular nerve) may be restricted in its function. In this case, the internal rotation is also severely restricted. As a result, the palm of the hand can only be brought to the back with great difficulty and with the help of the other muscles.
