It has been suggested that the tendons of the rotator cuff muscles blend with the ligaments and the glenoid labrum at their respected sites of attachments, so that the muscle contractions can provide additional stability by tightening the static structures during movement.[38]. Rotator cuff tears are the most frequent cause. There are about 20 muscles supporting the shoulder and allowing it to turn and rotate in many directions. Learn about its causes and home exercises that can help. Clavicle fractures in 2010: sling/swathe or open reduction and internal fixation?

Such breaks often occur because of the force exerted on the clavicle when a person falls onto his or her outstretched arm, or when the lateral shoulder receives a strong blow. The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis muscles; this grouping is also often abbreviated as SITS standing for the first letter in each muscles name. The role of the scapula. Stability is mostly offered by the periarticular muscles, that originate from the scapula and insert on the caput humeri. The success of a coordinated movement of the humeral head with normalized arthrokinematics, avoiding an impingement situation, requires the harmonious co-contraction of the RC tendons. Calis M, et al. Limited range of motion is a reduction in the normal range of motion of any joint. The Lymphatic and Immune System, Chapter 26.

Rotator cuff muscle performances during gleno-humeral joint rotations: An isokinetic, electromyographic and ultrasonographic study. et al. The synchronized contractions of the RC muscles must maintain the centralized positioning of the humeral head during movements in order to avoid the physical encroachment of tissues, predominantly anteriorly or superiorly to the GH joint, which has been linked to injury and pain amongst the shoulder region. Superior to the spine is the narrow supraspinous fossa, and inferior to the spine is the broad infraspinous fossa. medially to cover the entirety of the medial scapula.

The suprascapular notch is located lateral to the midpoint of the superior border. The scapula has several important landmarks (Figure 8.1.2). Scapula deviated about 35 degree anterior to the frontal plane.the concave glenoid fossa articulate with convex head of humerus to form glenohumeral joint. (c)- (d) Anterior bending of the head or vertebral column is flexion, while any posterior-going movement is extension. A hard fall onto the elbow or outstretched hand can stretch or tear the acromioclavicular ligaments, resulting in a moderate injury to the joint. Take care to clarify the patients description of the anatomical site. The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. Moreover, it is estimated that only 25% of the humeral head articulates with the glenoid fossa at any one time during movements.

If you retract your shoulder (relieving Serratus Anterior) and try to flex it at the same youll notice that your arm wont raise nearly as far. The three margins or borders of the scapula, named for their positions within the body, are the superior border of the scapula, the medial border of the scapula, and the lateral border of the scapula. The medial two-thirds of the fossa give origin to the Infraspinatus; the lateral third is covered by this muscle. This rotator cuff includes the m.supraspinatus, m. infraspinatus and m. subscapularis.

In this case, the acromion is thrust under the acromial end of the clavicle, resulting in ruptures of both the acromioclavicular and coracoclavicular ligaments. All of these fossae provide large surface areas for the attachment of muscles that cross the shoulder joint to act on the humerus. The remaining corner of the scapula, between the superior and lateral borders, is the location of the glenoid cavity (glenoid fossa). Paper presented at: Manipulative Physiotherapists Association of Australia Conference Proceedings., 1997; Melborne, Australia.

Most often, the levator scapula muscle and rhomboid muscles are short and the upper trapezius muscle is long. When weakness or neuromuscular dysfunction of the scapular musculature is present, normal scapular arthrokinematics become altered,[20] and ultimately predisposes an individual to an injury of the GH joint. Of the four, the biceps brachii, coracobrachialis, and brachialis are found in the anterior compartment while the triceps brachii can be found in the posterior compartment.

During flexion of the elbow, the brachialis always contracts and remains in flexion until the movement is finished. In addition, the clavicle of each pectoral girdle is anchored to the axial skeleton by a single, highly mobile joint (the sternoclavicular joint). Tillman B, Petersen W: Clinical anatomy. Bony instability of the shoulder. Furthermore, the shoulder allows for scapular protraction . At the shoulder, the coracoid process is located inferior to the lateral end of the clavicle. The first and second ribs descend, while the 4-6th ascend and the 3rd acts as an axis. The larger muscles such as the trapezius, the levator scapula, the pectorali, the deltoids, the serratus anterior, the latissimus dorsi, the rhomboids, the teres major, the biceps, the coracobrachialis, and triceps muscles are responsible for various synergistic activities during shoulder movements. Struyf F, Nijs, J., Baeyens, J.P., Mottram, S., Meeusen, R. Scapular positioning and movement in unimpaired shoulders, shoulder impingement syndrome, and glenohumeral instability.

For example, the medial side of the knee is the side closest to the other knee whereas the lateral side of the knee is the outside of the knee. clavicle deviated 20 degree with frontal plane in anatomic position. Chin Med J (Engl). Neer CS. The neuromuscular control of the scapula relies on the balanced team-work between the global movers and the fine-tuning stabilizing muscles of the shoulder complex. DOI: Shoulder pain and common shoulder problems. Another prerequisite for normal movement is that the scapula should be able to move freely, relative from the dorsal thorax wall. Which movements are limited, as this can help isolate the problem. The scapula also has three corners, two of which are the superior and inferior angles. A medial orientation is a position toward the midline of the body. The stabilizing muscles of the GH articulation, http:///index.php?title=Biomechanics_of_the_Shoulder&oldid=291225, Elevation and protraction = anterior elevation, Elevation and retraction = posterior elevation, Depression and protraction = anterior depression, Depression and retraction = posterior depression. Key palpable structures include: A comprehensive neurological examination may be warranted in patients that present with a primary complaint of shoulder pain. The supraspinatus muscle contributes to preventing excessive superior translation, the infraspinatus and teres minor limit excessive superior and posterior translation, and the subscapularis controls excessive anterior and superior translation of the humeral head, respectively. When performing actions with your arms over your head, do your arms feel heavier? Manual Therapy 5:6371, 2000.

And you dont need to be a gym-goer to, Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. The inferior angle is the most inferior portion of the scapula, and is particularly important because it serves as the attachment point for several powerful muscles involved in shoulder and upper limb movements. The joint depends primarily on the muscles and ligaments for its support, stability and integrity. These provide attachments for muscles of the arm. Depression Screening tools such as the Beck Depression Inventory (BDI) or the Depression Anxiety Screening Scale (DASS) are useful in screening patients for depression.
