What does the acromioclavicular joint articulate with?
The acromioclavicular joint is a diarthrodial joint defined by the lateral clavicle articulating with the acromion process as it projects anteriorly off the scapula. The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement.
Which bones articulate at the acromioclavicular joint?
The acromioclavicular (AC) joint is the articulation between the two bones of pectoral girdle; the clavicle and scapula. It is a plane synovial joint, with flat articular surfaces which are approximately the same in size.
What is Acromio clavicular?
The acromioclavicular (AC) joint is formed by the cap of the shoulder (acromion) and the collar bone (clavicle). It is held together by strong ligaments (figure 1). The outer end of the clavicle is held in alignment with the acromion by the acromioclavicular ligaments and the coracoclavicular (CC) ligaments.
Where is the Acromio clavicular ligament?
Superior acromioclavicular ligament This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion.
What are the articulating bones?
The Articulating bones are bones that move within a joint, for example the Articulating bones for the elbow joint are: Humerus. Radius. Ulna.
Which two joints articulate with the scapula at the clavicle and the humerus?
The shoulder joint itself known as the Glenohumeral joint, (is a ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula) The acromioclavicular (AC) joint (where the clavicle meets the acromion of the scapula)
What ligaments stabilize the sternoclavicular articulation?
The posterior sternoclavicular ligament provides the primary anteroposterior stabilization of the SC joint. It is a ligament that extends from the posterior aspect of the sternal end of the clavicle to the posterosuperior manubrium.
How serious is AC joint?
Leaving your AC joint injury untreated means your condition can worsen, which can have serious consequences, such as: Severe shoulder separation. Serious displacement or collarbone fracture. Arthritis in your shoulder.
How do you treat acromioclavicular joint pain?
Acromioclavicular (AC) Joint Injury Treatment Goals and Options
- Icing the shoulder.
- Putting your arm in a sling to decrease motion.
- Taking NSAIDs, like ibuprofen or naproxen, to help with pain.
How do you fix a acromioclavicular joint?
The AC joint is one of the few joints in the body that you can live without a portion of the bone making up the joint. The surgery can be done through a small incision about 1-inch long, or it can be done with several small incisions using an arthroscopic technique.
What are the three types of articulations?
The 3 Types of Joints in the Body
- Immovable (Fibrous) Joints.
- Slightly Movable (Cartilaginous) Joints.
- Freely Movable (Synovial) Joints.
What are the three major articulations of the shoulder?
The shoulder girdle is composed of the clavicle and the scapula, which articulates with the proximal humerus of the upper limb. Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.
What are the points of articulation between the humerus and scapula?
The shoulder joint itself known as the Glenohumeral joint, (is a ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula)
How long is recovery from AC joint surgery?
Time, rest and gradual rehabilitation typically result in a shoulder free of pain and functional limitations. The recovery time varies from patient to patient, but full recovery typically occurs within 6-12 weeks. A return to contact sports may require more recovery time to reduce the risk of re-injury.
