Muscles of the Shoulder

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Area of Science:

Orthopedics and Sports Medicine
Biomechanics of the shoulder joint

Background:

The scapula is crucial for optimal shoulder function, requiring proper alignment during upper extremity movement.
Scapular dyskinesis, or abnormal scapular motion, is a common clinical finding in shoulder pathologies.
This condition can be both a cause and a consequence of shoulder pain and dysfunction.

Purpose of the Study:

To review the causes of scapular dyskinesis.
To explore treatment options for scapular dyskinesis.
To provide an overview of managing scapular disorders.

Main Methods:

Literature review of studies on scapular function and dyskinesis.
Analysis of clinical findings related to scapular abnormalities.
Synthesis of current treatment strategies for scapular disorders.

Main Results:

Scapular dyskinesis represents an impairment of shoulder function.
It is frequently associated with various shoulder pain conditions.
Understanding the causes is key to effective management.

Conclusions:

Scapular dyskinesis is a significant indicator of shoulder pathology.
Comprehensive management strategies are needed for scapular disorders.
Addressing scapular issues is vital for restoring shoulder function.
