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 the joint classification of the AC joint?
The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement. As it attaches the scapula to the thorax, it allows an additional range of motion to the scapula and assists in arm movement such as shoulder abduction and flexion.
Which treatment should be perform at Type 3 AC dislocation case?
Majority of the orthopaedic surgeons will agree for surgical treatment of types 4–6 ACJ dislocation [2]. As for type 3 AC dislocation both early surgical treatment and nonsurgical treatment initially with late reconstruction if necessary have gained support.
How long does it take a Grade 2 AC joint separation to heal?
Return to activities — After a type II AC injury, most people are able to return to full activities when full range of motion and strength are regained, usually after two to four weeks. Gradually, add back activities as tolerated by pain or soreness. Complete healing generally requires several more weeks.
What is a Rockwood type II acromioclavicular AC joint injury?
type II: clavicle elevated but not above the superior border of the acromion. AC ligament: ruptured. CC ligament: sprain. joint capsule: ruptured. deltoid muscle: minimally detached.
What is a Grade 3 AC joint injury?
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 is an AC joint injury?
An AC joint injury describes an injury to the top of the shoulder. It occurs where the front of the shoulder blade (acromion) attaches to the collarbone (clavicle). Most often, trauma, such as a fall directly on the outside of the shoulder, causes an AC joint injury.
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.
Which grades of AC joint injury require surgery?
AC Joint Surgery Surgery is the clear choice for highly displaced AC joint separations (Grade 4, 5, and 6), and also for Grade 3 AC separations that demonstrate significant horizontal instability.
What is a Grade 2 AC joint injury?
Grade 2—Involves tearing of the joint covering (capsule) and stretching (but not tearing) of ligaments connecting the shoulder blade (scapula) and collar bone (clavicle). Frequently results in a small, permanent bump over the top of the shoulder at the AC joint.
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.
How does a Grade 3 AC separation heal?
Most Grade I – III AC separations are treated successfully with non-operative treatment that may include: ice to reduce pain and swelling. rest and a protective sling until pain subsides. This usually takes about 1-2 weeks.
