The superior angle of the scapula is thin, smooth, rounded, and inclined somewhat lateralward, and gives attachment to a few fibers of the levator scapulae muscle. The inferior angle of the scapula is the lowest part of the scapula and is covered by the latissimus dorsi muscle. It moves forwards round the chest when the arm is abducted Along with the trapezius, levator scapulae, and rhomboid muscles, the serratus anterior is a fixator or stabilizer of the scapula. It stabilizes the scapula as the arm is abducted to 90 degrees, and then helps laterally rotate the inferior angle of the scapula as the arm is further abducted to 180 degrees (straight overhead)
Scapula Anatomy Angles There are three angles found in the scapula bone diagram, The superior or medial angle of the scapula: It is covered by a trapezius muscle, and it is found formed at the junction of the medial and superior borders of the scapula. At the approximate level of the second thoracic vertebrae, the superior angle is found The main part of the scapula, the body, consists of a somewhat triangular-shaped flat blade, with an inferiorly pointing apex, referred to as the inferior angle as well as lateral and superior angles. The scapula is described as having superior, medial, and lateral borders. Posteriorly, the scapula is divided into a supraspinous fossa and. Scapula ossifies from 1 primary centre and 7 secondary centres of ossification ( 2 for coracoid process, 2 for acromion,1 each for glenoid cavity, inferior angle and medial border). Coracoid process fuses with the body of scapula by 16th year and all other centres fuse with body by 20th year Scapulohumeral rhythm can be observed by palpating the scapula's position as a person elevates the shoulder. Scapular landmarks for palpation are the base of the spine and the inferior angle. Scapulohumeral rhythm serves two purposes: It preserves the length-tension relationships of the glenohumeral muscles
The body of the scapula bone is thin although its borders, especially the lateral border, are thicker. The major defining characteristics of this bone are its: Three borders (superior, medial, lateral) Three angles (Superior, inferior, lateral) Two surfaces (dorsal, coastal) Three bony prominences (scapular spine, acromian, coracoid Externally, a normal scapula can be seen to have four angles (lateral, superior, inferior, and medial) formed from four borders (lateral, superior, inferior, and superomedial and inferomedial). The position of the medial angle is of significant importance in muscle biomechanics. 2 The glenoid fossa of the scapula or the glenoid cavity[help 1] is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus. This type of joint is classified as a synovial, ball and socket joint. The humerus is hel
A common cause of scapula pain is the straining of a muscle which can lead to muscle spasms. This can be brought on with repetitive motion of the hands, improper posture for prolonged periods of time, physical exercise overexertion, or damage to the muscle. The pain may be caused by myositis, a muscle tumor, or even a tear in the muscle The medial border (vertebral border) is the longest of the three, and extends from the medial to the inferior angle. It is arched, intermediate in thickness between the superior and the axillary borders, and the portion of it above the spine forms an obtuse angle with the part below.

Costal surfac The serratus anterior muscle originates at the 1st to 8/9th rib and inserts at the anterior surface of the medial border of the scapula (extending from the superior to inferior angles). The muscle is further divided into three parts: Superior part: 1st to 2nd rib → superior angle of the scapula. Intermediate part: 2nd to 3rd rib → medial.
Another common form of scapular dyskinesis is scapular winging wherein either the inferior angle or medial border of the scapula become more prominent. Inferior angle prominence would be associated with anterior tilting of the scapula, while medial border prominence would be associated with excessive scapular internal rotation Scapula, or shoulder blade is fixated to the axial skeleton solely via clavicle. Motions of the shoulder blade, to a great extent, facilitate the movements of the upper arm. Scapula in situ. Posterior oblique view. Note the flat shape of the shoulder blade - in some parts of the supraspinous and infraspinous fossas, the thickness is less than. A caudal angle joining the dorsal and caudal borders; A cranial angle joining the dorsal and cranial borders; A ventral angle bearing the glenoid cavity and separated from the proximal part of the scapula by the neck of the scapula. The glenoid cavity, for the articulation with head of humerus, is located at the ventral angle of scapula The scapular waist comprises the scapula and clavicle and together with the humerus and the external constitute the shoulder, a joint formed by 5 joints. When the scapula moves coordinately the humerus maintaining the axis of rotation of the humerus is called the scapulohumeral rhythm. Scapular dyskinesia are changes in position and scapular movements that predispose to shoulder injuries
The scapula AP view is a specialized projection of the scapular bone, performed in conjunction with the lateral scapular view. This projection can be performed erect or supine, involving 90-degree abduction of the affected arm. Indications This.. Lateral Scapular Slide Test (LSST) 7: This test is an objective measure for shoulder dyskinesia. How to perform: measure side to side difference of the distance from the inferior angle of the scapula to the adjacent spinous process in 3 different positions (shown below). A side to side difference of >1.5cm is considered pathological Features. It has two surfaces, three borders, and three angles. The anterior (front) side of the scapula shows the fossa subscapularis (subscapular fossa) to which the subscapularis muscle attaches.. The posterior surface of the scapula is divided by a bony projection, the spina scapulae (opposite to the fossa subscapularis) into the supraspinous fossa and the infraspinous fossa What are the 3 borders of scapula? Superior Angle of Scapula. (= Medial Angle of Scapula) Anterior Angle of Scapula. (= Lateral Angle of Scapula) Inferior Angle of Scapula
The scapula forms the posterior part of the shoulder girdle. It is a flat, triangular bone, with two surfaces, three borders, and three angles. 1 Surfaces.—The costal or ventral surface presents a broad concavity, the subscapular fossa. The medial two-thirds of the fossa are marked by several oblique ridges, which run lateralward and upward Results of previous reliability studies of scapular positioning, as well as those reported in this article, demonstrate that measurements of linear distance related to the scapula can be reliable. 11, 12 In our study, the examiners were able to locate, palpate, and measure the inferior angle of the scapula and the adjacent spinous process.
Scapula Bone Anatomy. The scapula, also called shoulder blade, is a triangle-shaped bone on the posterior side of the body that forms the posterior part of the pectoral girdle. Three is the magic number for the scapula: It has three depressions (called fossae), three borders, and three angles The starting position was the elbow extension and wrist neutral position in the standing pose, and the upward rotation angle of the scapula spine was measured at shoulder abduction angles of 0°, 45°, 90°, 135°, and 180° [22,23]. The ICC of scapula movement was 0.88 Objective: The purpose of this study was to determine which spinal segment most closely corresponds to the level of the inferior angle of the scapula (IAS) using measurements taken on A-P full-spine radiographs. Methods: Fifty sequentially selected radiographs were analyzed independently by two examiners. A straight edge was used to ascertain which spinal levels corresponded with the right and.

FIGURE 5-10 Lateral border of the scapula: Once you are at the inferior angle of the scapula, continue palpating superiorly along the lateral border of the scapula. It is easiest to feel the lateral border if your pressure is directed medially. Although challenging, the lateral border of the scapula can usually be palpated all the way to the infraglenoid tubercle of the scapula, just inferior. Borders of scapula: The Dorsal border is convex. Cranial & Caudal border are relatively straight. Angles of scapula: Cranial angle is blunt. Caudal angle is pointed. The distal angle has a Glenoid cavity and a beak/hook like developed Coracoid process, which is present on the cranio-medial aspect of the margin of the glenoid cavity mark is the inferior angle of the scapula (IAS), which is said to correlate with the T7, T8, or T9 spinous process or spinal level, depending on the source. 2-4 Gray's Anatomy indicates that the IAS corresponds to the level of the ninth rib, which attaches to the spine at the T8-9 inter to demonstrate particular scapular anatomy-For acromion and coracoid process— ex elbow and rest back of hand on lower back-For scapular body—raise arm up and rest forearm on head or reach across thorax and grasp opposite shoulder-Midcoronal plane at 45- to 60-degree angle to IR - Perpendicular to midmedial border of affected scapula The scapular muscles are important Serratus anterior Contributes to scapular upward rotation, posterior tilt and ER. The serratus anterior also helps stabilize the medial border and inferior angle of the scapular, preventing scapular IR (winging) and anterior tilt. Scapular IR and scapular anterior tilt, both of which decreas
The location of the inferior angle of the scapula in relation to the spine in the upright position: a systematic review of the literature and meta-analysis Chiropr Man Therap . 2015 Feb 27;23:7. doi: 10.1186/s12998-014-0050-7 7) Few fibres of the latissimus dorsi arise from the inferior angle of the scapula. 8) The insertion of the serratus anterior extends from the ventral aspect of the superior angle to the ventral aspect of the inferior angle. 9) Deltoid and trapezius are attached to the spine and the acromion Superomedial scapular angle was determined as angle between reference planes along superior and inferior scapular blades. Reference planes were generated along six standardized osseous footprints at medial base of scapular spine (1), superior angle of scapula (2), suprascapular notch (3), center of glenoid fossa (4), and medial (5) and lateral. vertebral border of the scapula, serving to protract the scapula [4, 8]. The inferior component originates from the sixth to ninth ribs and inserts on the inferior angle of the scapula [4, 8]. This third portion serves to protract the scapula and rotate the inferior angle upward and laterally [4]. As a whole, the main function of the serratus.
17 muscles attach to the scapula (in alphabetic order): biceps brachii (both heads) coracobrachialis. deltoid. Subsequently, question is, which muscle inserts on the flat anterior surface of the scapula? Serratus anterior muscle - its insertion is along the medial border, from the superior angle to the inferior angle Scapular fractures are uncommon, accounting for only 3-5% of shoulder girdle fractures and fewer than 1% of all fractures [].High-energy trauma is the most common cause, and scapular fractures are frequently associated with other acute injuries, including rib fracture (53%), lung injury (47%), head injury (39%), spinal fracture (29%), and clavicle fracture (25%) []
Borders. There are three borders of the scapula: The superior border is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process.It is referred to as the cranial border in animals. Of the three borders of the scapula, the superior border (or superior margin) is the shortest and thinnest; it is concave, and extends from the medial angle to. Teres major also originates on the scapula on the caudal angle and adjacent caudal border and the caudal surface of the subscapularis and also helps to flex the shoulder, rotate it medially, and prevents lateral rotation when weight bearing and also inserts on the major tuberosity of the humerus and is also innervated by the axillary nerve Glenopolar (GP) angle ≤22°; Angulation ≥45° Source: The Scapula Institute - St. Paul / Minnesota (www.scapulainstitute.org). Careful evaluation of the GP angle should be performed to prevent misinterpretation of the correct measurement. A GP angle ranging from 30° to 45° is considered normal 20
the portion of the scapula that runs inferomedially from the infraglenoid tubercle to the inferior angle: it is an important site of attachment for the teres major m. and teres minor m.; it has a groove for passage of the circumflex scapular a. inferior angle: the angle of the scapula formed by the union of the medial and lateral border The shoulder angle is determined by measuring the angle of the joint created at the point of the shoulder between the wither-to-shoulder line (the scapula) and the shoulder-to-elbow line (the humerus). Angles are created at joints. 90 degrees is an adequate shoulder angle. Less than 90 degrees is a 'closed' shoulde The scapula moves by gliding against the chest wall in three degrees of freedom; Elevation (range of motion 40°) - depression (RoM 10°) Protraction (20°) - retraction (15°) External rotation (60°) - Internal rotation (30°) During these movements, the scapula is stabilized by the muscles that attach to it and by the ligaments of the AC joint Scapula Bone - Introduction. The scapula is a flat, triangular-shaped bone that lies adjacent to the posterior surface of ribs. Seventeen muscles attach to the scapula, and it articulates with the clavicle to form the shoulder girdle or pectoral girdle, which supports movements of the humerus
Collimate to include the entire scapula (laterally to skin margin, medially to cover the medial border, superior to the skin margin, inferior to the inferior angle of the scapula) Cassette - 10×12, lengthwise, with grid ; SID - 40″ Exposure - approximately 70 kVp and 14mAs (+ or -) Now that we have that out of the wa The coordinates of the scapulothoracic joint uniquely span the functional kinematics of the scapula while the recommended ISB angles parameterize a (Y-X-Z) gimbal joint at the clavicle. It is difficult to interpret the location and orientation of the scapula from Euler angles of the gimbal joint without visualization of its spatial location Winged scapula treatment. Applying ice or cold therapy may help reduce the shoulder blade pain although the back isn't the easiest place to apply a cold pack. Assistance will be required! A full rehabilitation and strengthening program consisting of exercises for the shoulder is important. The most important muscle to strengthen if you have a Winged scapular is the serratus anterior muscle Compression of the dorsal scapular nerves leads to scapular instability and back pain. From the superior angle of the clavicle it runs with an artery along the medial margin of the scapula and underneath the rhomboid muscles. Along this path the nerve supplies small branches to the levator scapulae, rhomboid major, and rhomboid minor muscles
Scapular dyskinesis is an alteration in the normal position or motion of the scapula during coupled scapulohumeral movements.It occurs in a large number of injuries involving the shoulder joint and often is caused by injuries that result in the inhibition or disorganization of activation patterns in scapular stabilizing muscles. It may increase the functional deficit associated with shoulder. Lateral rotation is brought about by the trapezius (its upper fibres raise the acromion process and its lower fibres depress the medial end of the spine of the scapula) and serratus anterior (its lower 5 digitations pull the inferior angle of the scapula forwards and laterally) The scapular winging in dorsal scapular nerve syndrome is not as severe as seen with serratus anterior muscle and trapezius.] The usual complaint in dorsal scapular nerve entrapment is a history of the abnormal movement of the shoulder joint, and stiff joint. The patient may also complain of pain in the shoulder region The angular scapular angle osteomyogenous flap overcomes this disadvantage by providing superior pedicle length when compared with the circumflex scapular artery for scapular reconstructions. 23-27 Seitz et al 28 performed anatomical evaluation of 135 angular arteries and determined variable branching patterns The most medial border of the scapula (vertebral border) is approximately 5 cm from the vertebral column, although this distance varies depending on scapular protraction and retraction (Figures 1 and 2).The long axis of the scapula lies in a plane that is 30 to 45 degrees anterior to the coronal plane because of the curve of the rib cage [6, 7]..
