Topics of the lesson: Shoulder region: borders, layers, fascial-cellular formations; topography of the neurovascular structures of the shoulder; position of fragments at humerus fractures. Elbow region: borders, layers, cubital fossa; fascial formations. Elbow joint: articular capsule, its weak points, ligament apparatus; blood supply and innervation of the elbow joint; position of the bones at joint dislocation. Forearm region: borders, layers, fascial-cellular formations; topography of the neurovascular structures; position of fragments at forearm bones fractures. Distal radioulnar joint: borders, articular capsule, its weak points, ligament apparatus; synovial sheaths of tendon; blood supply and innervation of the joint.
