summary of the video with the time for reference:

1. Sterno clavicular joint structure 1:00
plane synoivial joint
saddle shaped
incongruent

2. S-C joint disc 2:00
fibrocartilagenous
increases congruence and stability
Therefore sc joint dislocation and degeneration is rarely seen

3.LIGAMENTS

-Inter clavicular ligament 6:00
prevents depression of scapula

-Sterno clavicular ligament 6:50
provides stability
reinforces capsule

-Costoclavicular ligament 7:11
anterior and posterior lamina
responsible for inferior glide of clavicle
reduces forces on the disc
