Acromioclavicular Joint Sprain – Kinesiotape Tutorial
In the above video, you watched a kinesiotape application to address an acromioclvicular joint sprain. So, what exactly is an acromioclavicular joint sprain you ask?
The acromioclavicular joint (AC Joint) is the connection between the clavicle (collarbone) and the acromion (bony process off the shoulder blade). It effectively connects the front of your body to the back of your body through the collarbone and shoulder blade. It is considered part of the shoulder complex, and is commonly injured in shoulder contact type sports (namely hockey and football). Certainly, this joint could be injured in any sport or fall, but in a situation where a hit is lead with the shoulder, this joint is put at risk.
There are there ligaments that hold the AC Joint together. They are 1) Superior Acromioclavicular Ligament (encapsulates the joint), 2) the Coracoacromial Ligament (attaches the end of the acromion to the coracoid process, another bony process off the shoulder blade), and 3) the trapezoid/conoid ligament complex (named for its shape, attaches the clavicle to the shoulder blade).
There are three variances or degrees of an AC Joint sprain. A Grade 1 sprain is simply a stretching of the ligaments, causing no severe deformity. Grade 2 sprains are more severe in nature, resulting from the acromioclavicular ligament disruption, and can typically cause a sort of step sign, or a depression of the acromion in relationship to the clavicle. And Grade 3 sprains are considered a complete disruption (in most cases) of all three ligament complexes, resulting in the end of the collarbone at the shoulder to be deformed in a way where it sticks up away from the shoulder joint. This might require some surgery.
My kinesiotaping method is effective for Grade 1 and 2 sprains, but I would typically refer a Grade 3 sprain along to a competent shoulder surgeon for evaluation.
As always, thank you for watching, and enjoy your spring!
