There are more than one ‘joints’ that form the shoulder; the ‘synovial’ bit where the proximal head of the humerus sits against the glenoid fossa of the scapula forms the bit everyone things of as the shoulder joint, however this is just the most mobile, articulating part that gives rise to movement (and the head of the humerus can be dislocated away from the glenoid fossa in any direction - commonly what people often have and know as a ‘shoulder dislocation), which is the most mobile part, and there is the acromioclavicular joint, which is also a synovial joint, but with only gliding movement in one plane, and much shorter ligaments surrounding it to form a firmer stabilisation. It is located superioanteriorly to the glenohumeral articulation (ball and socket of the shoulder where the arm attaches). This joint can rupture with a humoral dislocation. Quite painful, and gives rise to compromised stability of the entire ‘shoulder complex’ 🙂
I hope that helps? Any fundamental anatomy text has this info in it, if you’d like to review if it’s interesting..? ☺️
So, if any word is of a shoulder popping out, it could be a pure dislocation (totally not located properly) head of humerus from the glenoid fossa, or it could mean a rupture (separation) of the AC joint, or a combination thereof.
the only way to accurately find it is with excellent physical (hands on) examination, or an X-ray/other imaging.
There are other ligamentous structures that hold everything in the right place besides these two main structures, but for specificity here, we will leave them aside for now 🌺🙂
Sounds complex regarding the mobility and laxity in joints you’ve described, and muscles lock down to try to complements for fundaments loss of stability - which is what joint capsules combined with ligaments are supposed to do, and muscles are really there to give secondary support along with movement (muscles aren’t meant to provide primary joint stability).
Yes, sweetheart..I had a very bad injury… I was put back together with metal and stitches in most places darling 🙂🌺💜
I haven’t had a hip replacement, however both hips (top of leg at pelvis joints) have been resurfaced and repaired around the joint capsules and the bone chips removed from that area) 🙂
I think I might make choc blueberry muffins 😀😋
ok I hope the revisions go well, and smoothly for you BoP 🤗🌺
