  • Elbow= hinge joint Allows for flexion, extension 3 bones- H,R,U Ulna has olecrenon (hook shape)- articulates on trochlea Radius is smaller than ulna, does not directly articulate w/ humerus, radial head is round- allows radius to ride on the capitellum Humeroulnar joint- allows for extension, flexion Radioulnar joint- pivot joint, allows supination, pronation Humeroradial joint- supination, pronation
  • Ulnahumeral- olecranon impinging on the olecranon fossa  prevents ulna from dislocating posteriorly Another stabilizer is the
  • Elbow is one of the most stable joints in the body, but a dislocation is not uncommon Most associated w/ sports injuries Olecranon is unlocked from the trochlea, articular surfaces become out of position
  • Before reduction, the doctor performs a neurovascular assessment to make sure that the elbow is not impinging on any vessel/nerve Anesthetic can be used to help relax the muscles
