Question 1: what are the routine projections of the forearm?

Answer:

AP and Lateral (when performing long bones - include both joints (articular extremities) on the image) Question 2: a small process above the capitellum on the lateral side of the distal humerus

Answer:

lateral epicondyle Question 3: a spool shaped structure which articulates with the half-moon shaped semilunar notch of ulna. these allow the elbow joint to ______ and ______ as a ______ joint

Answer:

trochlea; flex and extend; hinge

Question 4: the distal radioulnar joint is a ______ joint

Answer:

pivot

Question 5: if a joint is clipped on the images doing a routine projection of the forearm what would you perform?

Answer:

a cone-down projection on a 10x12 image receptor of the joint excluded from the first exposure (always include the joint nearest the injury on the longest image receptor)

Question 6: accommodates the coronoid process of ulna in flexion

Answer:

coronoid fossa

Question 7: articulates with the olecranon process of ulna in extension

Answer:

olecranon fossa

Question 8: the anterior beak like process on the proximal ulna is called the?

Answer:

coronoid process

Question 9: the longer medial bone of the forearm

Answer:

ulna Question 10: The AP Projection is performed with the hand supinated to avoid what?

Answer:

radial crossover of the ulna

Question 11: where is the ulna located in the true anatomical position

Answer:

on the medial (5th finger) side of the forearm Question 12: soft tissue structure of the elbow joint that attaches to the brachialis muscle and to the radial tuberosity allowing the flexion of the forearm at the elbow joint

Answer:

biceps tendon

Question 13: when pronating the hand, the radius turns medially and crosses over the ulna due to the ______ movements of the ______ joints

Answer:

pivotal; radioulnar Question 14: the articular capsule of the elbow joint is lined with a synovial fluid which does what for the joint?

Answer:

lubrication of the joint

Question 15: The bones that make up the forearm

Answer:

radius and ulna

Question 16: the anterior fat pad is located within the?

Answer:

coronoid fossa above the trochlea of the humerus Question 17: in extension, the radial head articulates with the ______ of the distal humerus?

Answer:

capitellum

Question 18: what do the 3 fossa of the distal humerus accommodate?

Answer:

flexion and extension

Question 19: the distal radioulnar joint is a _____ joint

Answer:

pivot Question 20: in flexion, the radial head articulates with a small fossa on the distal humerus called the?

Answer:

radial fossa

Question 21: in extension, the olecranon process articulates with?

Answer:

olecranon fossa of the distal humerus

Question 22: the shortest of the two bones in the forearm is the?

Answer:

radius Question 23: the three areas of fat associated with the elbow joint are referred to as?

Answer:

fat pads Question 24: the coronoid process of ulna articulates with what when the elbow joint is in flexion?

Answer:

coronoid fossa of humerus Question 25: in flexion, the coronoid process articulates with ______ ______ of the distal humerus

Answer:

coronoid fossa Question 26: the radial head articulates with what when the elbow joint is in extension?

Answer:

capitellum or capitulum of the humerus Question 27: the olecranon process is separated from the coronoid process by the?

Answer:

semilunar or trochlear notch Question 28: the distal radioulnar joint along with the proximal radioulnar joint, allows the hand to what?

Answer:

supinate and pronate
