What is the Rockwood classification for?

Classification system The Rockwood classification takes into account not only the acromioclavicular joint itself but also the coracoclavicular ligament, the deltoid, and trapezius muscles, whilst considering the direction of dislocation of the clavicle with respect to the acromion.

What is a Grade 4 AC separation?

A grade 4 AC separation occurs when the clavicle is severely displaced posteriorly. It is defined as “significant” posterior displacement. The grade separation definition does not have any quantifiable distance as it is determined simply by the impression of the clinician.

What is a Grade 3 AC joint separation?

Grade 3—Involves tearing of the joint covering (capsule) and ligaments connecting the shoulder blade (scapula) and collar bone (clavicle). Causes a mild to moderate permanent bump over the top of the shoulder at the AC joint. Pain typically lasts 4-8 weeks. Surgery is usually not required.

What are the Rockwood classifications types of AC joint injury?

A Type I injury is a mild sprain of the AC ligament, Type II is a ruptured AC ligament and sprained CC ligaments, Type III is a superior dislocation of the AC joint with ruptured AC ligament, CC ligament, and joint capsule, Type IV is a posterior dislocation of the AC joint with ruptured AC ligament, CC ligament, and …

What is a Type 5 AC joint separation?

Grade 5—Involves tearing of the joint covering (capsule) and ligaments connecting the shoulder blade (scapula) and collar bone (clavicle), and the end of the collar bone (clavicle) tears through the muscle covering (fascia) above it. Results in a large, permanent bump over the top of the shoulder at the AC joint.

What is Conoid ligament?

The conoid ligament attaches to the clavicle at the conoid tubercle, which is posterior medial to the trapezoid tubercle. From superior to inferior, the conoid ligament appears as an inferior pointing cone.

What is a Grade 5 AC separation?

Does grade 4 AC separation require surgery?

A separated shoulder determined to be grade 4–6 typically requires surgery to repair. Treatment for grade 3 is less clear-cut. Some grade 3 injuries require surgery, while others do not, depending on the patient and the type of activity she or he wants to return to after treatment.

What is a Grade 1 AC joint separation?

Grade I – A slight displacement of the joint. The acromioclavicular ligament may be stretched or partially torn. This is the most common type of injury to the AC joint. Grade II – A partial dislocation of the joint in which there may be some displacement that may not be obvious during a physical examination.

What grade is my AC joint injury?

AC Joint Separation Grading Scale A grade 1 AC joint separation is a mild shoulder separation where the AC ligament is partially torn or stretched. A grade 2 AC joint separation is a partial separation of the AC joint. The AC ligament is completely torn but the coracoclavicular (CC) ligaments are still intact.

What is a Grade 5 shoulder separation?

Does Grade 5 shoulder separation require surgery?

Grade 4, 5, and 6 separations are severe injuries with high degree of displacement of the clavicle with respect to the acromion and usually require surgery. Figure one summarizes the classification of AC joint injuries.

Where is conoid ligament located?

What is Interclavicular ligament?

The interclavicular ligament was located close to the base of the sternal notch in all specimens. It connected the superior portions of the capsule of the sternoclavicular joints of each side. Its fibers formed a strong band along the posterior aspect of the upper border of the manubrium.

Does Grade 3 AC separation require surgery?

Most people do well without surgery. The severe injury (Grade 3) can be treated either nonoperatively or operatively. Non-operative treatment involves immobilisation in a sling for two to three weeks followed by a course of physiotherapy.

What is a Type 2 AC joint separation?

In a type II shoulder separation, the acromioclavicular (AC) ligament is completely torn, and the coracoclavicular (CC) ligament is either partially torn or not injured.

What percentage is a Grade 3 AC joint separation?

If the distance between the two bones is between increased between 25 and 100% it is a grade 3 and if it is more than that it is a grade 5. A grade 4 ac separation is one where there is significant posterior movement of the clavicle relative to the acromion.

What is a Grade 5 AC joint separation?

What is a Type 3 shoulder separation?

A shoulder separation is the partial or complete separation of two parts of the shoulder: the collarbone (clavicle) and the end (acromion) of the shoulder blade (scapula). A type III shoulder separation occurs when both the acromioclavicular (AC) and coracoclavicular (CC) ligaments are completely torn.

What is X-ray Tossy classification of dislocation?

x-ray Tossy classification divides dislocations in AC joint into three grades. It was later extended by Rockwood et al. by another three types. Normal width of AC joint is considered 1-3mm, widened AC joint has >7mm in men or >6mm in women.

What is the Tossy classification of AC joint dislocation?
