Upper left or right arm weakness can be caused by nerve damage or compression of the shoulder, repetitive strain injury of the shoulder, or a pinched nerve in the neck. Read below for more information on upper arm pain and weakness and when you should seek medical attention Infraspinous Fossa. The structure indicated is the infraspinous fossa of the scapula. It is called the infraspinous fossa because it lies below (infra) the spine of the scapula (-spinous). Accordingly, the fossa that lies superior to the spine of the scapula is the supraspinous fossa. The scapula consists of two surfaces - the costal surface and the posterior surface Supraspinatus tendinopathy is a common source of shoulder pain in athletes that participate in overhead sports (handball, volleyball, tennis, baseball). This tendinopathy is in most cases caused by an impingement of the supraspinatus tendon on the acromion as it passes between the acromion and the humeral head This study reports a high level of clinical infraspinatus atrophy in the dominant shoulder of elite female tennis players. Infraspinatus atrophy was associated with a higher performance ranking, and no functional deficits or associations with concurrent shoulder disorders were found. Team physicians A spinoglenoid notch cyst (SGNC) is a ganglion cyst located in the spinoglenoid notch (between the lateral aspect of the scapular spine and the infraspinous fossa) that most commonly results from a superior labral tear.

If the flap is elevated deep to the this muscular fascia, the dissection can become confusing and especially difficult around the pedicle where the fascia surrounds the triangular space
The muscles of the shoulder are associated with movements of the upper limb. They produce the characteristic shape of the shoulder, and can be divided into two groups: Extrinsic - originate from the torso, and attach to the bones of the shoulder ( clavicle, scapula or humerus ). Intrinsic - originate from the scapula and/or clavicle, and. Of the 32 patients, 14 had cysts in the supraspinatus, 11 in the infraspinatus, five in the subscapularis, and two in the teres minor ().The imaging and surgical findings are shown in Table 2.The average size of the cysts was 1.8 cm, and the range was 0.5-5.2 cm. Thirty-one of the 32 patients had rotator cuff tears The scapula is described as having superior, medial, and lateral borders. Posteriorly, the scapula is divided into a supraspinous fossa and infraspinous fossa by the scapular spine. Anteriorly, on the costal surface, is the shallow subscapular fossa.

Welcome to the second of our series on the shoulder joint in yoga. The first article in the series discussed the subscapularis muscle, the main shoulder internal rotator. Now we're on to the antagonist muscles of the subscapularis, the infraspinatus and teres minor. The infraspinatus arises in a trough below the scapular spine, hence its name (infra means below) Shoulder impingement is a common cause of rotator cuff fraying, according to the AAOS. Over time, bone spurs can form underneath the shoulder blade and rub on rotator cuff tendons, especially when the arm is elevated. Extensive rubbing of the rotator cuff tendons can weaken the tendons and cause them to be frayed, which will increase the risk. Shoulder. Simply put, the shoulder, or shoulder joint, is the connection of the upper arm and the thorax. Comprising of numerous ligamentous and muscular structures, the only actual bony articulations are the glenohumeral joint and the acromioclavicular joint (ACJ). The shoulder allows for a large range of motion, but is also more prone to. The infraspinous fascia overlying the infraspinatus muscle and the teres major fascia overlying the teres major are particularly thick. If the flap is elevated deep to the this muscular fascia, the dissection can become confusing and especially difficult around the pedicle. In the medial incision the transverse arterial branch can be visualized

Objective: To study the clinical features and diagnosis of bursal-side partial-thickness rotator cuff tears. Methods: From August 1999 to June 2006, 38 patients with bursal-side partial-thickness rotator cuff tear were evaluated. Twenty-eight men and ten women of average age 45.7 years (range, 18-69 years) with 11 left and 27 right shoulders were studied Deep Muscles. Front muscles of the shoulder:The pectoralis minor muscle is a small triangular shaped muscle that lies deep to pectoralis major muscle and passes as three muscular slips from the thoracic wall (ribs III to V) to the coracoid process of the scapula. Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration 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.
