Sternoclavicular Joint

Best Sternoclavicular Joint Treatment In Madinaguda, Hyderabad

The sternoclavicular joint occurs between the proximal end of the clavicle and the clavicular notch of the manubrium of the sternum together with a small part of the first costal cartilage. The sternoclavicular joint is a saddle-type joint that allows movement of the clavicle, predominantly in anteroposterior and vertical planes, although some rotation also occurs. The ability to thrust the arm and shoulder forward requires sound function of this joint.

The anterior and posterior sternoclavicular ligaments are found anterior and posterior to the joint
The interclavicular ligament links the ends of the two clavicles to each other and to the superior surface of the manubrium of the sternum.
The costoclavicular ligament is positioned laterally to the joint and links the proximal end of the clavicle to the first rib and related costal cartilage

Sternoclavicular joint injuries

Usually only through significant force do the ligaments supporting the sternoclavicular joint become completely disrupted, enabling dislocation of the joint. The extent of the damage to the supporting ligaments and capsule dictates whether the joint subluxes or dislocates. Sternoclavicular joint injuries are graded into three categories.

First degree injury: a simple sprain, which involves an incomplete tear or stretching of the sternoclavicular and costoclavicular ligaments.
Second degree injury: the clavicle subluxes either anteriorly or posteriorly from its manubrial attachment.
Third degree injury: a complete rupture of the sternoclavicular and costoclavicular ligaments, permitting a complete dislocation of the clavicle from the manubrium.

Sternoclavicular Joint Injuries

Injuries to the sternoclavicular joint (SCJ) are relatively uncommon, accounting for less than 5% of shoulder girdle injuries.
The SCJ is generally a very stable joint due to it's very strong supporting ligaments. However, it can dislocate or become unstable.
This may follow trauma or injury. People who have lax joint ligaments (commonly known as "double-jointed") are more prone to dislocate the SCJ.
Following an injury the joint may become unstable and keep popping out (unstable) or remain dislocated.

Treatment:

Initial management is to try put the joint back into place. This generally requires admission to hospital and an anaesthetic.
Most patients settle over a few weeks, but a small minority can remain unstable and painful.
In these people the joint can be surgically stabilised.
