Subacromial Impingement - Acromial Conflict Syndrome

This pathological condition is related to an "anatomical and / or functional alteration of the cuff of the four rotator muscles, namely: supraspinatus, subspinous, subscapularis and teres minor. Their respective tendons pass through a narrow space between the acromion of the scapula and the head of the humerus (ie the upper bone of the upper arm). If this area shrinks, compression of the tendons is created which results in shoulder pain, particularly evident during an effort with the arm raised.

Treatment of subacromial impingement can be conservative (rest, ice packs, analgesic drugs, rubbed shoulder alignment, gradual postural re-education, etc.) or surgical.

which joins the arm to the chest, formed by the interlocking of three bones: the humerus (ie the long bone of the arm), the scapula (which forms the back of the shoulder) and the clavicle (located, instead, in the front ).

The bones that participate in the shoulder joint are connected to each other through a complex system of soft tissues (muscles, tendons and ligaments) which allow a wide range of movements.

Active shoulder movements are ensured by four tendons and as many muscles: this group - collectively called the "rotator cuff" - connects the head of the humerus to the scapula, stabilizes and favors the activities of the arm.

The components of the shoulder joint, joined to the tendon and muscle structures that surround them, are concentrated in a space of a few centimeters and are subjected to continuous stresses. The latter are also multidirectional, since the shoulder is also involved in the movements that affect the muscle bands of the arms, chest and back.

Shoulder movements are, then, among those that are carried out most frequently and, precisely for this reason, it is easier for problems to arise.
