Why is the clavicle S shaped?

The clavicle gives support to the shoulder girdle by acting as a strut between scapula and sternum. Due to its S-shape, the outer end describes a much larger rotation during arm elevation than its inner end.

Why is the clavicle curved?

The clavicle is a long, doubly curved bone that connects the arm to the body, located directly above the first rib. It acts as a strut to keep the scapula in place so the arm can hang freely.

Why are my clavicles not straight?

Why might one or both clavicles be out of alignment? This is most likely due to tight muscles or fascia. Tightness is often a result of past injuries, repetitive awkward movements, chronic poor posture, or a combination.

Why is the structure of the clavicle important for its function?

It provides structural support between the shoulder and the rest of the skeleton, and is one of the most frequently fractured bones in the body.

Why are my clavicles V shaped?

Sometimes the pecs, which attach more to the medial part of the clavicles, seem like they are overly tight and short. Sometimes, it feels like the upper traps are pulling on the top, lateral edge of the clavicles, creating a V shape. I call this Vee-ing of the clavicles.

Why is clavicle called beauty bone?

The clavicle, or collarbone, is also referred to as “beauty bone” because of its prominent body location. It is the only long bone that lies horizontally in the body. The shape of the clavicle appears elongated ‘S’ due to its unique anterior and posterior curvatures.

Does the clavicle Bend?

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.

Should my collar bone be horizontal?

Your collarbone (or clavicle) is the bone that runs horizontally between the top of your breastbone (sternum ) and shoulder blade (scapula). You can feel your collarbone by touching the area between your neck and your shoulder. A broken collarbone, also called a clavicle fracture, is when this bone breaks.

What is an SC joint?

The sternoclavicular (SC) joint is one of the four joints that complete the shoulder. The joint is located in the spot where the clavicle (collarbone) meets the sternum (breastbone) at the base of the neck. Although not common, problems with the SC joint can arise from injury and other disorders.

Can you dislocate a collarbone?

Because it’s so thin and close to the skin, the collarbone is one of the most commonly fractured bones. It’s second nature to put out your hand to stop a fall. But the force on your collarbone can cause a fracture or dislocation.

What is sternoclavicular syndrome?

Sternocostoclavicular hyperostosis (SCCH) is a chronic inflammatory disorder which presents with erythema, swelling, and pain of the sternoclavicular joint. Approximately one half of patients have acne or pustular lesions with the best described association being with palmoplantar pustulosis (PPP).

Does the clavicle rotate?

Tension in the coracoclavicular ligament produces a passive force that rotates the clavicle backward. Because the clavicle is shaped like a crank, backward clavicular rotation elevates the distal end of the clavicle and, with it, the acromion and the AC joint.

Is the clavicle part of the trunk or neck?

The bones that connect the upper extremity to the trunk are the clavicle, or collar bone, and the scapula, or shoulder blade.

Why does my sternoclavicular joint pop?

In moderate sprains, the joint becomes unstable. In rare cases, patients have a stable joint but a painful clicking, grating, or popping feeling. This indicates an injury to the intra-articular disc ligament. This type of injury causes pain and problems moving the SC joint.

What muscle moves the clavicle?

Of note here is the subclavius muscle, whose actions involve pulling the clavicle towards the sternoclavicular intra-articular disc and sternum. This functions to depresses the lateral end of clavicle and stabilizes the clavicle during movements of the pectoral girdle.

What does clavicle look like?

The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula, and each of these structures forms the pectoral girdle.

Why clavicle is a typical long bone?

Clavicle can be considered as a modified long bone as : It is the only long bone positioned horizontally and is subcutaneous throughout.

What is the hole between your collarbones called?

The suprasternal notch, also known as the fossa jugularis sternalis, jugular notch, or Plender gap, is a large, visible dip in between the neck in humans, between the clavicles, and above the manubrium of the sternum.
