Mike - Shoulder muscles involved

[Guest guest]

Hey Mike,

So far I have been told that my pectoralis and Scalenes are tight. I

am NOT sure what else yest but I do know my Ostepath is working on

these because they are so tight and likely to be causing some of my

dislocations.

Does this sound like they could be some of the mucles aiding in my

subclavicular shoulder dislocations.

No question at all about it for the pec major.

The upper fibers originate along the bottom, medial half of the

clavicle and insert on the greater tubercle of the humerus. They

flex the joint and also adduct it horizontally (pull it in toward

the body). The lower fibers orginate on the sternum and the

cartilage of ribs one through six. They insert on the greater

tubercle of the humerus also, but pass under the upper fibers and

actually attach on the arm above the insertion point of the upper

fibers. The extend the joint. I can definitely see where a really

tight pec major, particularly the upper fibers, could pull the arm

in under the clavicle.

I have my doubts about involvement of the scalenes because of

attachment points. There are three scalene muscles: anterior,

middle and posterior. They all originate on transverse processes of

the cervical vertebrae and insert on either the first or second

rib. They can affect your neck, but I don't see how they could make

your shoulder dislocate. I would suspect the deltoid and/or teres

major before any of the scalenes.

could the scalenes be tight as a secondary thing to the dislocations

(i.e because of where the shoulder sits when it is out, could this

be injuring etc the scalenes?? seeing as the attach to the 1st rib

etc)???

Definitely could be the case. Sometimes with compensatory holding

patterns, the muscle that hurts the worst is the one doing the

compensating - not the one causing the problem.
