What is acromioclavicular arthropathy?
The joint between the end of the clavicle and the acromion (Acromioclavicular Joint) moves and rotates with shoulder function. If it becomes inflamed or arthritic, it can produce pain and reduced shoulder function.
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.
What are the ligaments at the acromioclavicular joint?
Acromioclavicular (AC) joint
Type | Synovial plane joint; multiaxial |
---|---|
Ligaments | Intrinsic: Superior acromioclavicular ligament, inferior acromioclavicular ligament Extrinsic: Coracoclavicular ligament (with conoid and trapezoid parts) |
Innervation | Lateral pectoral nerve, suprascapular nerve |
What does the acromioclavicular ligament do?
The acromioclavicular ligament serves to reinforce the joint capsule and serves as the primary restraint to posterior translation and posterior axial rotation at the AC joint.
What is Moderate acromioclavicular osteoarthritis?
Osteoarthritis of the acromioclavicular (AC) joint is a common condition causing anterior or superior shoulder pain, especially with overhead and cross-body activities. This most commonly occurs in middle-aged individuals because of degeneration to the fibrocartilaginous disk that cushions the articulations.
What 3 ligaments stabilize the AC joint?
The AC joint capsule is quite thin, but has considerable ligamentous support; there are four AC ligaments: superior, inferior, anterior and posterior. The coracoclavicular (CC) ligament complex consists of the conoid and trapezoid ligaments.
What is mild acromioclavicular degenerative changes?
Acromioclavicular osteoarthritis is a type of shoulder arthritis that involves degenerative changes to the cartilage and other structures in the acromioclavicular joint—leading to pain, stiffness, and weakness in the front of the shoulder.
What is the articulation of the acromioclavicular joint?
Articulating Surface The AC Joint is the articulation between the lateral end of the clavicle and a small facet on the acromion of the scapula. The articular facets are considered to be incongruent, in that they vary in configuration. They may be flat, reciprocally concave-convex, or reversed (reciprocally convex-concave).
What is the grade of an acromioclavicular dislocation?
Acromioclavicular joint dislocations are graded from I to VI. Grading is based upon the degree of separation of the acromion from the clavicle with weight applied to the arm. Grade I is slight displacement of the joint, and a badly stretched or partially torn AC ligament. It has the normal separation of <4 mm.
Which is the articulation between the scapula and the clavicle?
The acromioclavicular articulation is an arthrodial joint between the acromial end of the clavicle and the medial margin of the acromion of the scapula. Its ligaments are: The Articular Capsule. The Articular Disk. The Superior Acromioclavicular. {Trapezoid and Conoid. The Inferior Acromioclavicular.
What kind of sports cause dislocation of acromioclavicular joint?
Acromioclavicular joint dislocation is particularly common in collision sports such as ice hockey, football, Judo, rugby and Aussie rules, and is also a problem for those who participate in swimming, horseback riding, mountain biking, biking, snow skiing and skateboarding.
