Answer:

olecranon fossa

Question 2: The arm is made up of which of the following bones?

Answer:

Humerus only, The "forearm" is the radius and ulna Question 3: For the AP projection of the thumb, Lewis suggests angling the CR toward the wrist to demonstrate the first metacarpal free of the sesamoids and of the soft tissue of the palm.What is the suggested CR angle?

Answer:

10-15 degrees Question 4: What positioning error can cause closing of the joints when doing finger images?

Answer:

Not keeping the finger extended and parallel to the IR

Question 5: What are the routine projections for the 1st digit? (Thumb)

Answer:

AP, PA Oblique, Lateral Question 6: For exact positioning of the PA oblique wrist, and to ensure duplication in follow-up examinations what should be used for positioning?

Answer:

45 degree foam wedge sponge Question 7: Which lateral projection of the humerus will provide a true lateral elbow w/out OID of the proximal Humerus

Answer:

Mediolateral projection with patient PA Question 8: Which projection of the wrist would be used to better demonstrate the carpal interspaces?

Answer:

AP, due to the oblique situation of the carpals and the divergence of the x-rays Question 9: If a patient is unable to extend the elbow for the AP projection what procedure can be done in its place?

Answer:

• images in partial flexion

One with the humerus parallel to IR One with the forearm parallel to the IR Question 10: . For the AP projection of the elbow, the humeral epicondyles are:

Answer:

Parallel to the IR

Question 11: What makes up the carpal tunnel?

Answer:

The carpal sulcus and the Flexor retinaculum The median nerve travels through this canal

Question 12: Soft tissue radiographs of the elbow in the lateral position are often ordered to

demonstrate:

Answer:

Fat Pads

Question 13: Which carpal is the smallest?

Answer:

Pisiform

Question 14: What is a Colle's fracture?

Answer:

Fx with posterior displacement of the distal Radius

Question 15: Which fat pads are seen on a negative lateral elbow radiograph?

Answer:

Anterior and Supinator Question 16: What structures does the trauma lateral projection (Coyle method) of the elbow demonstrate?

Answer:

Radial head, neck and tuberosity should be in profile, free of superimposition except for a small part of the coronoid process Demonstrates fractures and dislocations of the elbow, especially the radial head Question 17: Long & Raefort and Lewis describe 2 modifications of the thumb what are they and what do they demonstrate

Answer:

Long & Rafort: CR angle of 15 degrees proximally to the AP thumb

Lewis: angle 10-150 proximally to the MCP joint of the AP thumb

shows arthritic changes, fractures and displacement of the first CMC or a Bennett's Fracture Question 18: The IR must be elevated how many degrees for the PA axial projection of the wrist (Stecher method)?

Answer:

20 degrees: an alternative method of flat IR with 20 degree angle to the elbow of the CR will also work as the stecher method

Question 19: Describe the Arm Positioning and central ray location for the Trauma lateral

projection (coyle method) to demonstrate the coronoid process:

Answer:

Elbow flexed only 800 (900 will obscure the coronoid process). The CR is angled 450 from the shoulder toward the elbow entering the mid elbow Question 20: If the elbow is in full flexion is the olecranon pocess in or out of the olecranon fossa?

Answer:

Out of the fossa; The olecranon process is in the olecranon fossa when the elbow is extended.Question 21: If a patient is unable to extend the forearm for an AP projection of the elbow, how many projections are necessary to avoid distortion of the joint?

Answer:

2: partial flexion

Question 22: Stetcher suggests an alternative to the 20 degree elevation of the IR and wrist if not acheivable, what is it?

Answer:

IR and wrist parallel to the table with a 20 degree angle toward the elbow

Question 23: Medially the radial head articulates with what?

Answer:

The radial notch of the Ulna Question 24: Which parts of the upper extremity should be in contact with the tabletop for a PA projection of the wrist?

Answer:

1) arm 2) axilla 3) forearm All Three should be parallel to IR Question 25: For a PA projection of the second through 5th digits, the CR is directed to the:

Answer:

The Proximal Interphalangeal joint
