The Shoulder The shoulder includes the proximal humerus, the clavicle and the scapula, and their connections to each other, to the sternum (clavicle), and to the thoracic rib cage (scapula). Together, these elements form the most mobile joint in the human body (Figure 1).

Clavicle Medially, it articulates with the manubrium of the sternum (breast-bone) at the sternoclavicular joint. At its lateral end it articulates with the acromion of the scapula (shoulder blade) at the acromioclavicular joint. It has a rounded medial end and a flattened lateral end.

Proximal Humerus Fracture A proximal humerus fracture occurs when the ball, of the ball-and-socket shoulder joint, is broken. The fracture is actually at the top of the arm bone (the humerus). Most proximal humerus fractures are non-displaced (not out of position), but about 15-20% of these fractures are displaced, and these may require more invasive treatment.

Clavicle (Human Collarbone) Anatomy, Parts, Location and Functions Location of the Clavicle. The clavicle is located at the top of the thoracic wall, just below the neck and to the sides of the breastbone (sternum). It lies just above the first rib on either side of the anterior (front) chest wall.he human clavicle or collarbone is a short bone that lies on the front of the chest (thoracic) wall. It plays an important role in connecting the upper limb to the trunk of the body. The clavicle is also the most frequently fractured bone of the upper body especially since it lies superficially..

Clavicle In human anatomy, the clavicle or collarbone is a long bone that serves as a strut between the shoulder blade and the sternum or breastbone. There are two clavicles, one on the left and one on the right. The clavicle is the only long bone in the body that lies horizontally. Together with the shoulder blade it makes up the shoulder girdle. It is a palpable bone and in people who have less fat in this region, the location of the bone is clearly visible, as it creates a bulge in the skin.

Clavicle Fractures The patient may cradle the injured extremity with the uninjured arm. The shoulder may appear shortened relative to the opposite side and may droop. Swelling, ecchymosis, and tenderness may be noted over the clavicle. Abrasion over the clavicle may be noted, suggesting that the fracture was from a direct mechanism.

- -Locate the glenoid fossa (where the humerus and the scapula articulate-ie, make a joint), it faces laterally. Clavicle-The clavicle’s flat end articulates with the acromion of the scapula and the knobbed end articulates with the sternum. It is somewhat s-shaped and the medial half is convex anteriorly and the lateral half is concave anteriorly.

Broken Collarbone (Clavicle) - Topic Overview The collarbone (clavicle) is one of the main bones of the shoulder joint. It holds the shoulder up and, along with the shoulder blade (scapula) and acromioclavicular (AC) joint, provides stability and strength to the shoulder. The collarbone also protects nerves and blood vessels from the neck to the shoulder. What causes a broken collarbone?

- Fractures of the proximal pole of the scaphoid with associated avascular necrosis and nonunion are well known to be problematic. Many techniques for fixation and reconstruction of the proximal pole of the scaphoid have been reported, often with poor results. One of the newer modalities of treatment for these difficult cases is excision of the proximal pole and replacement with a pyrocarbon implant.

Clavicle The medial end is quadrangular and articulates with the clavicular notch of the manubrium sterni to form the sternoclavicular joint. The articular surface extends to the inferior aspect for attachment with the first costal cartilage.

Clavicle fracture A clavicle fracture, also known as a broken collarbone, is a bone fracture of the clavicle. Symptoms typically include pain at the site of the break and a decreased ability to move the affected arm. Complications can include a collection of air in the pleural space surrounding the lung, injury to the nerves or blood vessels in the area, and an unpleasant appearance. It is often caused by a fall onto a shoulder, outstretched arm, or direct trauma. The fracture can also occur in a baby during chil

1.1.2 The clavicle and scapula In the dry skeleton, here's the clavicle, here's the scapula. The proximal long bone of the upper extremity, the humerus, articulates with the scapula at the shoulder joint. The scapula and clavicle articulate with the bones of the thorax at one point only, here, at the sternoclavicular joint. The lateral end of the clavicle articulates with this projection on the scapula, the acromion, forming the acromio-clavicular joint.

Humerus Anterior view of the bones of the right shoulder, showing the clavicle (collarbone), scapula …Encyclopædia Britannica, Inc. In humans the articular surface of the head of the humerus is hemispherical; two rounded projections below and to one side receive, from the scapula, muscles that rotate the arm. The shaft is triangular in cross section and roughened where muscles attach.

Subclavian Steal Syndrome In the setting of severe proximal subclavian artery stenosis or occlusion, typically due to atherosclerotic disease, insufficient flow may be present to sustain the ipsilateral arm.In this case, the branches of the subclavian artery may be recruited to provide collateral retrograde flow to the upper limb.lthough retrograde blood flow in the vertebral artery is usually noted angiographically in association with proximal ipsilateral subclavian artery occlusion, subclavian steal may also occur with hemodynamically significant subclavian artery stenosis (see the image below). Irregular proximal subclavian stenosis.

Anatomy 1 Fractures commonly involve the clavicle (collar bone), proximal humerus (top of the upper arm bone), and scapula (shoulder blade). 2  Dislocations occur when the bones on opposite sides of a joint do not line up. 3  Dislocations can involve any of three different joints.

Clavicle fracture A clavicle fracture is a bone fracture in the clavicle, or collarbone. It is often caused by a fall onto an outstretched upper extremity, a fall onto a shoulder, or a direct blow to the clavicle.here is a clavicle on each side of the front, upper part of the chest. The clavicle consists of a medial end, shaft, and a lateral end. The medial end connects with the manubrium of the sternum and gives attachments to the fibrous capsule of the sternoclavicular joint, articular disc, and interclavicular ligament.
