The elbow joint has three distinct parts encompassed by a typical joint case. These are joints between the three bones of the elbow, the humerus of the upper arm, and the sweep and the ulna of the lower arm.
Joint:
*Humeroulnar joint is a straightforward pivot joint, and takes into account developments of flexion and augmentation as it were.
*Humeroradial joint is a ball-and-attachment joint.
*Proximal radioulnar joint In any situation of flexion or expansion, the span, conveying the hand with it, can be turned in it. This development incorporates pronation and supination.
At the point when in anatomical position there are four fundamental hard tourist spots of the elbow. At the lower some portion of the humerus are the average and sidelong epicondyles, as an afterthought nearest to the body (average) and as an afterthought far from the body (horizontal) surfaces. The third milestone is the olecranon found at the leader of the ulna. These lie on a level line called the Hueter line. At the point when the elbow is flexed, they frame a symmetrical triangle called the Hueter triangle.
At the outside of the humerus where it faces the joint is the trochlea. The depression running over the trochlea is, in a great many people, vertical on the foremost side however spirals off on the back side. This outcomes in the lower arm being adjusted to the upper arm amid flexion, however shaping an edge to the upper arm amid expansion — an edge known as the conveying edge.
The unrivaled radioulnar joint offers the joint case with the elbow joint yet assumes no utilitarian job at the elbow.
