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.
The serratus punch is an exercise that works scapular protraction using the serratus anterior muscle and to a lesser extent the pectoralis minor. [ 1 ] [ 2 ] The exercise even performed at maximum voluntary isometric contraction did not increase pain in one study in people with shoulder pain. [ 3 ]
Both strength and aerobic exercise have shown to be beneficial, [3] although strenuous and excessive exercise should be avoided. [1] Physical therapy can address contractures. [1] Orthopedic surgery address foot deformities, scoliosis, Achilles tendon contractures, and winged scapula.
Dorsal scapular nerve syndrome can be caused by nerve compression syndrome.A winged scapula is the most common symptom. [7] Shoulder pain may occur. [7] It causes weakness in rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. [7]
Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name, FSHD tends to sequentially weaken the muscles of the face, those that position the scapula, and those overlying the humerus bone of the upper arm.
The implications of scapular instability caused by the rhomboid major include scapular winging during scapular protraction, excessive lateral rotation and depression of the scapula, as the antagonistic action by the rhomboid major is absent. With scapular instability, movement in the upper extremity is limited as the scapula cannot guide the ...
Active exercises include the Pendulum exercise, which is used to strengthen the Supraspinatus, Infraspinatus, and Subscapularis. [9] External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles.
Serratus anterior muscle deficit is another cause of scapular winging and decreases the efficacy of an Eden–Lange procedure, but it can be overcome with a simultaneous pectoralis major transfer. [12] Muscular dystrophy often contraindicates tendon transfer, because the muscles transferred are either dystrophic or capable of becoming dystrophic.
