Forearm and elbow Flashcards
What structures form the elbow joint
Capitulum,
Trochlea,
Trochlea notch,
Head of the Radius
What structures form the proximal Radioulnar joint
Radial notch (on Ulna), Radial head
Where are the medial and lateral epichondyle located
Projections on the Distal Humorous
What are the purposes of the olecranon fossa, radial fossa and coronoid fossa
Accommodate the forearm bones during movement at the elbow
What can happen following direct damage to the elbow such as an supraepichondylar fracture
Interference of brachial Artery
Damage to Ulna, Radial or Median nerves
What can occur due to a medial epichondylar fracture
Damage to the Ulna nerve, Ulna claw
What does the proximal end of the Ulna articulate with
Trochlea
What is the Olecranon
Large projection of bone that forms part of Trochlea notch,
Triceps Brachii inserts here
What is the purpose of the coronoid process
It forms part of trochlea notch
What is the Ulna Tuberosity
Rough bone that the brachialis inserts to
What structures form the distal radioulnar joint
Styloid process,
Ulnar notch
What can a fracture of the olecranon result in
Part of the bone being pulled proximal due to triceps Brachii
What are 2 classical fractures of both Ulna and radius
Monteggias Fracture,
Galeazzis Fracture
What is the radial tuberosity
Bony projection that the Biceps Brachii attaches to
What 3 structures form the wrist joint
Scaphoid,
lunate,
2 facets on distal radius
