The scapula serves as the attachment site for a dinosaur's back and forelimb muscles. [15] If the scapula fails to properly elevate the acromion, impingement may occur during the cocking and acceleration phase of an overhead activity. The intrinsic muscles of the scapula include the muscles of the rotator cuff—the subscapularis, teres minor, supraspinatus, and infraspinatus. Vries, J. de, Tollenaere, F. de & Persijn, A.J.

Scapular dyskinesis refers to an altered motion or position of the scapula.The scapula in anatomy, also known as shoulder bone, connects the upper arm bone (the humerus) with the collar bone (the clavicle). [21], During the Middle Ages spathula was used to refer to the shoulder blade. The scapula is a wide, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrinsic, extrinsic, and stabilising and rotating muscles.

This interaction is important for the optimal function of the shoulder. The acromion forms the summit of the shoulder, and is a large, somewhat triangular or oblong process, flattened from behind forward, projecting at first laterally, and then curving forward and upward, so as to overhang the glenoid cavity. Abnormal scapular function is called scapular dyskinesis. The spelling humerus is actually incorrect in classical Latin.[22].

Lateral border shown in red. These various epiphyses are joined to the bone by the 25th year. Its lower third presents a broader, somewhat triangular surface, the inferior angle of the scapula, which gives origin to the Teres major, and over which the Latissimus dorsi glides; frequently the latter muscle takes origin by a few fibers from this part. n. An impairment in the ability to control movements, characterized by spasmodic or repetitive motions or lack of coordination. It is often associated with tightness at the anteriorside of the shoulder (in flexibility of the pectoralis major/ minor muscles) and weakness of the lower trapezius and serratus anterior muscles. "In terms of comparative anatomy the human scapula represents two bones that have become fused together; the (dorsal) scapula proper and the (ventral) coracoid. Scapular Dyskinesia. Position of scapula (shown in red). (1998). being a flat, broad blade, with the latter three words etymological related to each other. The epiphyseal line across the glenoid cavity is the line of fusion. The inferior angle of the scapula is the lowest part of the scapula and is covered by the latissimus dorsi muscle. An imbalance in these muscles often results in what is called scapula dyskinesis (a fancy name for a movement disorder of the shoulder blade). Ossification starts as membranous ossification before birth. In such animals, the scapula is usually a relatively simple plate, lacking the projections and spine that it possesses in mammals. [32], In fish, the scapular blade is a structure attached to the upper surface of the articulation of the pectoral fin, and is accompanied by a similar coracoid plate on the lower surface. The notion of scapular dyskinesis for the purposes of the present review does not include presentations where there is a defined abnormality of the neuromuscular system; for example, neuritis, neuropathy, neuropraxia or other forms of peripheral nerve injury.

The surgical neck of the scapula passes directly medial to the base of the coracoid process. In general, it can be a result of: bone factors, inflexibility factors, joint factors, kinetic chain problems, muscular damage, or nerve damage. Philadelphia/London: W.B.

The role of the scapula in athletic shoulder function. At its apex is a slight elevation, the supraglenoid tuberosity, to which the long head of the biceps brachii is attached. The lateral third of the fossa is smooth and covered by the fibers of this muscle. The surgical neck exits medial to the coracoid process.[14]. Between the 14th and 20th years, the remaining parts ossify in quick succession, and usually in the following order: first, in the root of the coracoid process, in the form of a broad scale; secondly, near the base of the acromion; thirdly, in the inferior angle and contiguous part of the vertebral border; fourthly, near the outer end of the acromion; fifthly, in the vertebral border. Further, an epiphysial plate appears for the lower part of the glenoid cavity, and the tip of the coracoid process frequently has a separate nucleus. Tools.

The extrinsic muscles include the biceps, triceps, and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula, infraglenoid tubercle of the scapula, and spine of the scapula. The anatomic neck of the scapula is the slightly constricted portion which surrounds the head and is more distinct below and behind than above and in front. [28] Similarly to the resemblance between the Latin pala (spade) and the shoulder blade, a resemblance might be felt between the shape of a shovel and the shoulder blade. Their activation and coupling are the most responsible for upward rotation, external rotation and posterior tilt of the scapula. Mannheim: Dudenverlag.

Dyskinesia refers to a category of movement disorders that are characterized by involuntary muscle movements, including movements similar to tics or chorea and diminished voluntary movements. As a sports physiotherapists it is important to evaluate the contributing factors to shoulder pathology. However, the detailed structure of these bones varies considerably in living groups. The surface is covered with cartilage in the fresh state; and its margins, slightly raised, give attachment to a fibrocartilaginous structure, the glenoidal labrum, which deepens the cavity. In the diagram below you can see the different pull of 3 muscles (lower traps, upper traps and serratus anterior) all attaching to the scapula.

The American Journal of Sports Medicine, 35(10), 1744. The base of the acromion is formed by an extension from the spine; the two nuclei of the acromion unite, and then join with the extension from the spine. It is unclear, however, whether some of these conditions are the result of the dyskinesis or the latter depends on those pathologies due to altered shoulder motion or defective muscle activation. At the upper part of the fossa is a transverse depression, where the bone appears to be bent on itself along a line at right angles to and passing through the center of the glenoid cavity, forming a considerable angle, called the subscapular angle; this gives greater strength to the body of the bone by its arched form, while the summit of the arch serves to support the spine and acromion. It moves forwards round the chest when the arm is abducted. Scapulohumeral rhythm (also referred to as glenohumeral rhythm) is the kinematic interaction between the scapula and the humerus, first published by Codman in the 1930s.
