Inferior angle of scapula

The scapula consists of two surfaces. The inferior angle of the scapula.

This position reveals that the medial border and the inferior angle of the scapula protrude from the posterior thoracic wall Figure 343.

Inferior angle of scapula. Scapular winging is best demonstrated by having the patient flex the shoulders to 90 extend the elbows and push against the wall with both hands Gregg et al 1979. This position reveals that the medial border and the inferior angle of the scapula protrude from the posterior thoracic wall Figure 343. The Inferior Angle of the Scapula As A Spinal Landmark.

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. Anatomical landmarks are sometimes used by clinicians in order to identify spinal levels.

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. Curved skin incision starts at lateral prominence of acromion courses medially along scapular spine and caudally to inferior angle of ScapulaDetach of deltoid from scapular spine and retract laterally deepen approach through interval between infraspinatus and teres minor original Judet posterior approach involved elevation of belly of infraspinatus which was then reflected laterally to.

The inferior angle of the scapula IAS can be located using the rule 7 up 6 down referring to the position of the IAS in relation to the thoracic SPs in the upright and prone positions respectively 25-27. Spot checking the T7 SPIAS benchmark can also be found in other professions. There are also three angles to the scapula.

The superior border meets the lateral border at the lateral angle and with the medial border at the superior angle. The third angle is the inferior angle where the medial and lateral borders meet. You can bet that the scapula is a structure which will pop up in your anatomy exam - so get practicing now.

This can cause a seesaw effect and force the bottom of the scapula to poke out. This is also known as a winging scapula. When this pulling occurs the muscles in the area of the inferior angle of he scapula will set off a pain signal because they are being over pulled and are trying to pull the scapula back in place.

Inferior Angle Of Scapula. Quizlet is the easiest way to study practice and master what youre learning. Create your own flashcards or choose from millions created by other students.

More than 50 million students study for free with the Quizlet app each month. 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.

4th to 89th rib medial border and inferior angle of the scapula. The lowest attachment may alternatively extend to the 10th rib in approximately 10 of the population as well as blend with the external abdominal oblique muscle The inferior part of the muscle is the most prominent and powerful one.

The inferior angle of the scapula. It is the lowest part of the scapula covered by a muscle called latissimus dorsi muscle. As a union of medial and lateral borders of the scapula this inferior angle is found present.

The surface present at the back provides attachment to the fibres of the latissimus dorsi muscle and to the teres major. The inferior angle is the lowest part of the scapula and is formed by the junction of the medial and lateral margins. The latissimus dorsi muscle covers this angle.

The posterior aspect of the inferior angle gives attachment to the teres major and often to a few fibers of the latissimus dorsi muscle. The aim of this study is to describe the anatomy of fractures of the inferior angle and the adjacent part of the scapular body based on 3D CT reconstructions. In a series of 375 scapular fractures we identified a total of 20 fractures of the inferior angle of the scapular body 13 men 7 women with a mean patient age of 50 years range 3373.

Scapula fractures occur infrequently in children and are usually the result of major trauma with multiple injuries. This is because the scapula is well protected by surrounding musculature. Therefore fractures usually involve the glenoid coracoid process and acromion.

Fractures of the inferior angle of the scapula are very rare in children. Inferior angle of scapula IAS fractures are rare with very few cases reported. They typically present with pain loss of shoulder motion and scapula winging.

Operative and nonoperative treatments have been trialed with varying success. The aim of this study was to gather data relating to IAS fractures to develop evidence-based treatment. The scapula is a bone that connects the humerus with the clavicle.

The scapula consists of two surfaces. The superior angle of the scapula is covered by the trapezius muscle. It is formed at the point where the medial and lateral borders meet and provides attachment for the.

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. 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. 24 Grays Anatomy indicates that the IAS corresponds to the level of the ninth rib which attaches to the spine at the T89 inter-space5 In another study on the location of the IAS we.

Medial scapula from the scapular spine to the inferior angle. Dorsal scapular nerve C5. Rhomboid minor Spinous process of C7 T1 Ligamentum nuchae Supraspinous ligament.

In addition to scapular protraction the lower portion ro-tates the inferior angle of the scapula upward and laterally. As a unit the serratus anterior muscle acts to pro-tract and stabilize the scapula ori-enting the glenoid for effective use of the upper extremity. The serratus anterior.
