1. Fractured collarbone (clavicle): A direct blow to the shoulder or falling onto an outstretched arm can cause a fracture of the collarbone.
2. Fractured upper arm bone (humerus): A direct blow to the shoulder or a fall onto an outstretched arm can cause a fracture of the upper arm bone.
3. Dislocated shoulder: A sudden impact or fall can cause the upper arm bone to pop out of its socket in the shoulder blade.
Rotator cuff tear: A rotator cuff tear occurs when the tendons that attach the shoulder blade to the upper arm bone are torn or strained. This can happen from a sudden impact or repetitive overhead motions.
4. Labral tear: The labrum is a ring of cartilage that surrounds the shoulder socket. A traumatic injury can cause a tear in the labrum.
5. AC joint separation: The AC joint is where the collarbone meets the shoulder blade. A traumatic impact can cause a separation of the joint.
6. Sternoclavicular joint (SC joint) separation: The SC joint is where the collarbone meets the breastbone. A traumatic impact can cause a separation of the joint.
These injuries can vary in severity and may require different types of treatment, ranging from rest and rehabilitation to surgery. It is important to seek medical attention immediately if you suspect you have a shoulder injury following a traumatic accident.
