- Subacromial bursitis is a common cause of shoulder pain that is usually related to shoulder impingement of your bursa between your rotator cuff tendons and bone (acromion). Your subdeltoid bursa is less commonly inflamed shoulder bursa.

- The rotator cuff is a group of muscles that include the subscapularis and supraspinatus, which cause medial rotation and abduction of the arm, as well as the infraspinatus and teres minor, which together cause lateral rotation of the arm, all at the shoulder.

What Are the Names of the Muscles in the Arm & Shoulder? The rotator cuff consists of four muscles -- supraspinatus, infraspinatus, teres minor and subscapularis -- that originate on your shoulder blade and attach to your upper arm bone. Together, these muscles keep the ball of your upper arm bone in the socket as you move your shoulder. The supraspinatus lifts your arm out to the side. The infraspinatus and teres minor muscles rotate your arm outward, and the subscapularis muscle rotates your arm inward.

Pain management guide Pain management health centre. Shoulder pain: Causes, diagnosis, treatment. The shoulder is one of the largest and most complex joints in the body. The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. The acromion, or acromion process, is a bony projection off the scapula.

- Internal rotator muscle-a term that is commonly used to refer to the subscapularis muscle, which affects internal rotation of the shoulder. Interscalene block-a procedure that is used to provide pain relief for shoulder surgery.

Shoulder Impingement Syndrome What is impingement syndrome? Shoulder impingement syndrome, which is sometimes called swimmer’s shoulder or thrower’s shoulder, is caused by the tendons of the rotator cuff muscles becoming impinged as they pass through a narrow bony space called the subacromial space.

Anatomy The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint. The rim deepens the socket by up to 50% so that the head of the upper arm bone fits better.

Scapho-lunate advanced collapse arthritis Scapho-lunate advanced collapse arthritis. Scapho-lunate advanced collapse arthritis or SLAC occurs as the result of unrecognised injury to the ligament between the scaphoid and the lunate. This ligament is a very important one in the wrist and is the most frequently injured in falls onto the outstretched hand.

- Arthroscopic Acromioplasty. This condition occurs when the Supraspinatus tendon rubs on the under surface of an extension of the shoulder blade known as the Acromium. This results in a painful shoulder which is exacerbated with lifting the arm to or above shoulder height and is usually painful to sleep on at night.

MAJOR MUSCLES OF THE CARCASS A = serratus ventralis. B = rhomboideus. Like other shoulder muscles around the scapula, most of these muscles are intermediate in their level of toughness. 1  The serratus ventralis is a large fan-like muscle that radiates from the medial face of the scapula and attaches to the lateral surfaces of the ribs. = rhomboideus.

Serratus Anterior Comments. The serratus anterior holds scapula against thoracic wall. A winged scapula condition indicates weakness of serratus anterior. They also help stabilize scapula during shoulder internal and external rotation when shoulder is 90° abduction (Ekstom RA, et al. 2003; Myers JB, et al.

Rotator cuff In anatomy, the rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle.

Shoulder Assessment & Diagnosis The following can be used in the shoulder: Empty can (tinny) test: Hold your arm out straight in front of you with the thumb facing downwards. Raise and lower the arm (as if emptying a can!). Pain indicates injury to the Supraspinatus muscle or tendon.

Scapho-lunate advanced collapse arthritis S.N.A.C. wrist. Scaphoid non-union advanced collapse is a different variation of the SLAC wrist. Failure of the scaphoid to unite following a fracture can result in a similar picture of arthritis. The initial investigation is very similar to the SLAC wrist and the options for treatment much the same.

Shoulder The collection of muscles and tendons in the shoulder is known as the rotator cuff. It stabilizes the shoulder and holds the head of the humerus in the glenoid, a shallow cavity in the scapula. The muscles of the rotator cuff include the suprasinatus, infraspinatus, teres minor, and subscapularis.

Shoulder Impingement â 3 Keys to Assessment and Treatment To me, this is more for the bursal sided, or subacromial, impingement and refers to what structure the rotator cuff is impinging against. As you can see in the pictures below (both side views), your subacromial space is pretty small without a lot if room for error.

SLAP Tear of the Shoulder Essentially the labrum of the shoulder deepens the shoulder socket. A specific type of injury to the labrum, or labral tear, is called a SLAP tear. SLAP stands for Superior Labrum from Anterior to Posterior. The SLAP tear occurs at the point where the tendon of the biceps muscle inserts on the labrum. Common reasons for a SLAP tear include: Fall onto an outstretched hand; Repetitive overhead actions (throwing)

- The rotator cuff is the support structure for the shoulder joint. When a tear occurs, patients experience pain and difficulty in abducting or rotating the arm. The incidence of traumatic rotator cuff tears is unknown, 18 but it is thought to be relatively uncommon in younger athletes.

- Sometimes, excessive use of the shoulder leads to inflammation and swelling of the bursa between the rotator cuff and part of the shoulder blade known as the acromion. The result is a condition known as subacromial bursitis.

Mount Adams (Washington) Since the end of the 2004-2008 eruptions at Mount St. Helens, scientists at the Cascades Volcano Observatory and the Pacific Northwest Seismic Network have been monitoring the subtle inflation of the ground surface and minor earthquakes -- just like the ones seen after the 1980 eruptions.

Anatomy The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid. Surrounding the outside edge of the glenoid is a rim of strong, fibrous tissue called the labrum. The labrum helps to deepen the socket and stabilize the shoulder joint.

Teres minor The teres minor is a slim, narrow muscle within the rotator cuff, located in the shoulder. It is involved in the external rotation of the shoulder joint.The other muscles composing the rotator cuff are the supraspinatus, infraspinatus, and subscapularis.It connects the scapula to the humerus, along with the teres major and infraspinatus muscles, which lie on either side and overlap the teres minor.Along with the infraspinatus, the muscle keeps the head of the humerus in place where it joins with the scapula.t connects the scapula to the humerus, along with the teres major and infraspinatus muscles, which lie on either side and overlap the teres minor.

Shoulder Labrum Tear The shoulder labrum is a thick piece of tissue attached to the rim of the shoulder socket that helps keep the ball of the joint in place. The labrum can tear a few different ways: 1) completely off the bone, 2) within or along the edge of the labrum, or 3) where the bicep tendon attaches.
