About This Presentation

Description : Check out this medical PowerPoint presentation titled "Elbow joint (articulatio cubiti)” by Dr. Anna L. Kiss.

This medical PowerPoint presentation is about the elbow joint, also known as the articulatio cubiti. The elbow joint is a complex joint that connects the upper arm bone (humerus) to the two forearm bones (radius and ulna). It is a synovial joint, which means it has a joint capsule filled with synovial fluid that lubricates the joint and reduces friction.

The elbow joint consists of three main components:

Humeroulnar joint: This joint allows the hinge-like movement of the arm, and it is formed by the articulation of the trochlea of the humerus with the trochlear notch of the ulna.
Humeroradial joint: This joint allows the arm to rotate, and it is formed by the articulation of the capitulum of the humerus with the head of the radius.
Proximal radioulnar joint: This joint allows the forearm bones to rotate around each other, and it is formed by the articulation of the head of the radius with the radial notch of the ulna.

The elbow joint is stabilized by ligaments, tendons, and muscles. The ligaments are strong bands of connective tissue that connect the bones and provide stability to the joint. The tendons attach muscles to bones and allow for movement. The muscles around the elbow joint include the biceps, triceps, brachioradialis, and brachialis, among others.

Injuries to the elbow joint can include dislocations, fractures, sprains, and strains. Treatment for these injuries can include rest, immobilization, physical therapy, and in some cases, surgery.

Articulatio cubiti: 3 joints inside of a common capsule Humeroulnar joint: hinge joint (ginglymus) 1 axis: transversal Humeroradial joint: ball-and-socket joint (articulatio spheroidea) 3 axises Does not have important function Proximalradioulnar joint: pivot joint (trochoid) 1 axis: longitudinal + Articulatio radioulnaris distalis Articulatio cubiti: trochoginglymus Sobotta Sobotta

Joint capsule origin: anteriorly above the coronoid fossa and radial fossa posteriorly: above the olecranon fossa. medial and lateral epicondyles are out of the capsule!!!! Muscles are originating from there!!! insertion: below the coronoid process of the ulna; 1.5 cm below the articular circumference of the radius (for the pronation-supination: recessus sacciformis (sup) Sobotta Thiel fibrous layer synovial layer zsírszövet Capsule: antero-posteriorly: loose laterally:tight (collateral ligaments!)
