Where is the sternum clavicle?
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.
Why is one end of the clavicle called the sternal end?
The medial end, known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.

Can the clavicle separate from the sternum?
Sternoclavicular separation is an uncommon sprain of the ligaments of the sternoclavicular joint (the junction between the breastbone [sternum] and the collarbone [clavicle]).
What type of joint is between the clavicle and sternum?
The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum. The SC joint is the only true articulation connecting the upper limb to the axial skeleton, and that it's the least constricted joint in the human body.
What is the clavicle?
The clavicle is an elongated, S-shaped bone that rests horizontally at the sternum across the upper part of the ribcage, and the acromial end of the scapula . This bone is an important part of the skeletal system since it plays an essential role in everyday functional movement, serving as the connection between the axial skeleton and the pectoral girdle.
What is the lateral third of the clavicle?
The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds). Each end has unique bony landmarks, depending whether the superior or inferior surface of the bone is viewed.
What is the cartilage of the sternoclavicular joint?
Like the acromioclavicular joint, the sternoclavicular joint is surrounded by an articular cartilage capsule, but with a fibrocartilage articular disk inside that creates a clavicular and a sternal synovial cavity. Sternoclavicular joint ligaments stabilize the joint on its anterior and posterior surfaces.
Why is the synovial joint important?
This synovial joint is important as it anchors the clavicle and scapula to the axial skeleton. However the joint enables a variety of limited movements of the arm, including: protraction and retraction. depression and elevation. slight rotation.
Where is the conoid tubercle found?
The conoid tubercle, which is found more laterally towards the acromial end. It appears as a rough eminence found where the flat portion of the clavicle meets the tip of the pyramidal sternal end.
Where is the acromial facet?
The superior surface of the clavicle has a smooth appearance. The acromial facet can be seen at the far posterior edge of the acromial end. It appears as a small flattened oval surface and enables the clavicle to articulate about the acromion of the scapula in the acromioclavicular joint.
Which joint is formed by the acromial end of the clavicle and the acro
Acromioclavicular joint. The first is the acromioclavicular joint, which is formed by the acromial end of the clavicle and the acromion of the scapula respectively. It enables slight gliding movement about the shoulder region.
Where is the clavicle located in 2021?
The clavicle, also referred to as the collar bone, is an elongated, S-shaped bone that sits between the shoulder and sternum at the top of the ribcage. It provides structural support between the shoulder and rest of the skeleton, and is one of the most frequently fractured bones in the body.
What joint is the clavicle?
The clavicle joins the scapula, or shoulder blade, and sternum to form two joints on either end of the bone, which are: 1. Acromioclavicular (AC) joint: The acromioclavicular joint forms between the acromion of the scapula and clavicle at the top of the shoulder, held together by the acromioclavicular ligament.
What is AC in acromioclavicular?
Acromioclavicular (AC) Joint Sprain or Separation. Trauma to the acromioclavicular joint, such as a direct blow to the front of the shoulder or falling and landing on an outstretched hand, can injure the ligaments holding the acromion and clavicle together. This can result in either an acromioclavicular joint sprain or separation of the joint.

What is the function of the clavicle?
Function. The clavicle connects the shoulder to the rest of the skeleton. Its positioning allows for increased range of motion of the shoulder away from the body and helps protect the arm by dispersing force transmitted through direct contact. 2 .
Why does osteolysis occur at the end of the clavicle?
Osteolysis, or bone degeneration, can easily occur at the end of the clavicle due to the high degree of stress and repetitive forces placed through the small surface area of the acromioclavicular joint, especially with heavy lifting such as bench press or military press.
Where is the sternoclavicular joint?
Sternoclavicular joint: The sternoclavicular joint forms between the sternum and clavicle at the front of the chest, and is supported by the costoclavicular ligament. The relative size of the clavicle leaves it particularly susceptible to fracture. Fracture of the clavicle can occur from a fall landing on an outstretched hand or through ...
What is the linkage between the clavicle and the sternum?
The sternoclavicular (SC) joint is the linkage between the clavicle (collarbone) and the sternum (breastbone). The SC joint supports the shoulder and is the only joint that connects the arm to the body.
Which side of the clavicle is pushed forward?
Anterior—the end of the clavicle is pushed forward, in front of the sternum (breastbone) Posterior—the end of the clavicle is pushed backward, behind the sternum and deep into the upper chest. Although both kinds of dislocations are serious injuries, a posterior dislocation requires more urgent medical attention.
Where is the sternoclavicular joint?
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.
What is the most common injury to the SC joint?
Injuries to the SC joint can range from a mild sprain, in which the surrounding ligaments are stretched (the most commonly seen injury), to a fracture of the clavicle (collarbone) itself. In rare cases, a strong blow to the shoulder can cause an injury in which the joint dislocates completely from its normal position.
How to tell if you have SC joint disorder?
Symptoms. The most common symptom of an SC joint disorder is pain in the area where the clavicle meets the sternum. This pain will be present with a sprain but will be much sharper in the case of a fracture or dislocation—especially when you attempt to move your arm. Other signs and symptoms may include:
What is posterior dislocation?
In a posterior dislocation, the vital structures behind the SC joint can be compressed, leading to life-threatening problems with breathing or blood flow. (Top) Normal shoulder anatomy. (Center) In an anterior dislocation, the end of the clavicle is pushed forward, in front of the sternum.
