    00:01 In this lecture, we'll look at the joints of the upper limb.

    00:05 So, first of all, we'll start with the sternoclavicular joint.

    00:08 And then, we're going to move across to the acromioclavicular joint, followed by the glenohumeral joint, the elbow joint, the proximal radioulnar joint, the distal radioulnar joint, and then, we'll look at various joints within the wrist at the carpal bones, the carpometacarpal joints, important joints within the hand, and then finally, the metacarpophalangeal joints and the interphalangeal joints.

    00:34 So, let's take a tour through the joints of the upper limb. Let's start with the sternoclavicular joints.

    00:40 It's really associated as its name suggests, as all of the names of the joints suggest between the sternum.

    00:47 But this time, the proximal end of the clavicle is articulating with the sternum at its clavicular notch, specifically, of the manubrium of the sternum.

    00:57 So, the proximal end of the clavicle attaching to the manubrium of the sternum.

    01:03 There's also a slight interaction with the first costal cartilage.

    01:06 And here, we can see the articular cavity between those two which is occupied by an articular disk.

    01:13 Here, we can see it's covered as many of the joints are, by a joint capsule and here, we can see strengthening of that joint capsule by various ligaments.

    01:22 Here, we have the anterior sterno-clavicular ligament.

    01:25 And as there's an anterior version, we'll find we also have a posterior version.

    01:30 So, the anterior and posterior sternoclavicular ligaments.

    01:34 Here, we can see running from this joint all the way across the superior surface of the manubrium to the other sterno-clavicular joints, we have the interclavicular ligament.

    01:45 Attaching the clavicle and holding it in place against the first web, we have the costoclavicular ligament as well.

    01:53 If we then, move on to the movement of the sternoclavicular joint, there's not that much mobility in this space.

    01:59 There's a little bit of elevation and a little bit of depression. Here, we can see this looking at the anterior aspect.

    02:04 And then, if we have a look superiorly down onto the superior surface of the manubrium on the right and the clavicle extending towards the left, we can have protraction with the clavicle moving anteriorly and we can have retraction with the clavicle moving posteriorly.

    02:22 There's also minimal rotation axially around the axial aspect of the clavicle.

    02:29 It can rotate very slightly.
