A winged scapula (scapula alata) is a skeletal medical condition in which the shoulder blade protrudes from a person's back in an abnormal position. In rare conditions it has the potential to lead to limited functional activity in the upper extremity to which it is adjacent. It can affect a person's ability to lift, pull, and push weighty objects.
Exercises that strengthen the back muscles include rows, pull-ups, and shoulder blade squeezes. Exercises like doorway stretches for the chest can help stretch out tension that contributes to rounded shoulders. Synergistically implementing muscle strengthening and stretching can effectively prevent the development of rounded shoulders. [47] [48]
Cable pull-down exercise to the front with a medium-width overhand (pronated) grip. The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle.
The scapula plays an important role in shoulder impingement syndrome. [8] It is a wide, flat bone lying on the posterior thoracic wall that provides an attachment for three different groups of muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, infraspinatus, teres minor and supraspinatus. [9]
An example of trapezius function is an overhead press. When activating together, the upper and lower fibers also assist the middle fibers (along with other muscles such as the rhomboids) with scapular retraction/adduction. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward.
The original technique was first described by Eden [4] in 1924 and verified by Lange in the 1950s. [5] [6] The rhomboid major and rhomboid minor were transferred laterally from the medial border of the scapula to the infraspinatous fossa, and the levator scapulae was transferred laterally to the spine of the scapula, near the acromion.
The long thoracic nerve that supplies the serratus anterior muscle is vulnerable during certain types of surgery (for example, during lymph node clearance from the axilla for breast cancer). Damage to this nerve is the most common cause of winged scapula. [6]
