postoperative analgesia for such procedures (4). They are field blocks that aim to deposit the local anesthetic between the pectoralis major and minor muscles and between pectoralis minor and serratus anterior respectively to block the different peripheral nerves supplying the
scapular spine. - Nerve supply: It is innervated by the spinal accessory nerve. - Action: It functions mainly as a scapular retractor and elevator of the lateral angle of the scapula[19]. The rhomboids muscles: The rhomboids, consisting of the major and minor muscles. - Origin: the major and minor muscles originate from the spinous processes of C7 and T1 and T2 to T5, respectively. - Insertion: They insert on the medial aspect of the scapula. - Nerve supply: The dorsal scapular nerve innervates the
Rick Winstead Steve Hammons PTA 150 2/13/15 Brachial Plexus At first glance, the brachial plexus may be a bit intimidating. The nerves arising from it and the muscles of the trunk and upper extremity of which it innervates may seem overwhelming, but as one begins the process of adding all of the components together in an orderly fashion, it begins to be seen in a much more easily understood manner. The first step in this process is to gain a grasp on the basic main structure of the plexus, and
Physiology The breasts or mammary glands are sometimes considered a part of the reproduction system. Structurally, they are modified sweat glands. They are composed of mainly fat, breast tissue, nerves, veins, arteries, and connective tissues. The breast is usually situated on top of the pectoral major muscles covering the second rib to the sixth or seventh rib and extends from the sternum to the mid-axillary line. Breast tissue has an axillary tail which extends into the armpit region.
(Peterson and Redlund-Johnell, 2009). Functional movements of the joint include flexion, extension, abduction, adduction both frontal and transverse plane, medial and lateral rotation and circumduction. The shoulder also allows for scapular protraction, retraction, elevation, and depression (Quillen, Wuchner, Hatch, 2004). The primary stabilisers of the shoulder are the biceps brachii (anterior side of the

if arthroscopic or open, can cause severe postoperative pain and discomfort. Several analgesic techniques, such as intra-articular injection of local anaesthetics, parenteral opioids, brachial plexus block, and selective suprascapular and axillary nerve block are used with different success and side effect profile. The interscalene brachial plexus block remains the mainstay for analgesia In shoulder surgery. The interscalene block technique is more effective in controlling postoperative pain, causing
