Upper limb
| Question | Answer |
|---|---|
| The name of the joint between the proximal and distal phalanges of the first digit | Interphalangeal joint |
| The joints between metatarsal and phalanges are the | Metacarpophalangeal joint (MCP) |
| In the anatomic position, which of the bones of the forearm is located on the lateral side? | Radius |
| In the anatomic position, which of the bones of the forearm is located on the medial side? | Ulna |
| Fracture and dislocation of the posterior lip of the distal radius | Barton's fracture |
| Most common type of primary malignant tumor occurring in bone | Multiple myeloma |
| Reduction in the quantity of bone or atrophy of skeletal tissue | Osteoporosis |
| Spain or tear off the ulnar collateral ligament | Skier's thumb |
| An abnormality of the cartilage affecting long bones | Achondroplasia |
| Transverse fracture extending through the distal aspect of the metacarpal neck, most often the 5th metacarpal | Boxer's fracture |
| Transverse fracture of the distal radius with posterior displacement of the distal fragment | Colles fracture |
| Narrowing of joint space with periosteal growths on the joint margins | Osteoarthritis |
| Fluid filled joint space with possible calcification | Bursitis |
| Possible calcification in the carpal sulcus | Carpal tunnel syndrome |
| Soft tissue swelling and loss of fat pad detail visibility | Osteomyelitis |
| Mixed areas of sclerotic and cortical thickening along with radiolucent lesions | Osteoporosis |
| For AP projection of the elbow, the epicondyles must be _________ to the IR | Parallel |
| Which routine projection of the elbow best demonstrates the radial head,neck and tuberosity with slight superimposition of the ulna | AP oblique with lateral rotation |
| Which projection of the elbow best demonstrates the coronoid process in profile? | AP oblique with medial rotation |
| How many bones make up the phalanges of the hand? | 14 |
| How many bones make up the carpal region? | 8 |
| What is the total number of the bones that make up the hand and wrist? | 27 |
| What is the joint between the two phalanges of the first digit? | Interphalangeal joint |
| What joint is between the first metacarpal and the proximal phalanx of the thumb? | First metacarpophalangeal joint (MCP) |
| What joint is between the middle and distal phalanges of the fourth digit? | Fourth distal interphalangeal joint (DIP) |
| What is the joint between the carpals and the first metacarpal? | First carpometacarpal joint (CMC) |
| What is the joint between the forearm and the carpals? | radiocarpal joint |
| What is the joint between the distal radius and ulna? | Distal radioulnar joint |
| Which carpal contains a "hooklike" process? | Hamate |
| Which carpal is most commonly fractured? | Scaphoid |
| Which two carpal bones are located most anteriorly as seen on a lateral wrist radiograph? | Trapezium and Scaphoid |
| Which bone of the upper limb contains the coronoid process? | Proximal ulna |
| Where are the coronoid and radial fossae located? | Anterior aspect of the distal humerus |
| Which two bony landmarks are palpated to assist with positioning of the upper limb? | Lateral and medical epicondyles |
| True/False To visualize fat pads surrounding the elbow, exposure factors must be adjusted to see both bony and soft tissue structures | True |
| True/False Anterior and Posterior fat pads of the elbow are best seen on correctly positioned and correctly exposed AP elbow projections | False |
| Why should a forearm never be taken as a PA projection? | Causes the proximal radius to crossover the ulna |
| In what position should the hand be for an AP elbow projection? | Supinated |
| In what position should the hand be for an AP medial rotation oblique elbow position? | Pronated |
| Which projection of the elbow best demonstrates the coronoid process in profile? | AP, medial rotation oblique |
| Which projection of the elbow best demonstrates the radial head and tuberosity without superimposition? | AP, lateral rotation oblique |
| Which projection of the elbow best demonstrates the olecranon process in profile? | Lateral elbow |
| Which projection of the elbow best demonstrates the coronoid tubercle in profile? | Lateral elbow |
| Which projection of the elbow best demonstrates the trochlear notch in profile? | Lateral elbow |
| Which projection of the elbow best demonstrates the capitulum and lateral epicondyle in profile? | AP, lateral oblique |
| Which projection of the elbow best demonstrates the olecranon process seated in olecranon fossa? | AP, medial oblique |
| Accumulated fluid within the joint cavity | Joint effusion |
| A reduction in the quantity of bone or atrophy of skeletal tissue | Osteoporosis |
| Local or generalized infection of bone or bone marrow | Osteomyelitis |
| Inflammation of the fluid-filled sacs enclosing the joints | Bursitis |
| Fracture of the base of the first metacarpal | Bennett's fracture |
| Painful disorder of hand and wrist from compression of the median resulting nerve | Carpal tunnel syndrome |
| A radiograph of a PA oblique of the hand reveals that the 3rd, 4th and 5th metacarpals are superimposed. What must be done to correct this? | Decrease obliquity of the hand |
| A radiograph of an AP elbow demonstrates total separation between the proximal radius and ulna. What must be done to correct this? | Rotate upper limb medially |
| A radiograph of the carpal canal projection reveals the pisiform and hamulus are superimposed. What can be done to correct this? | Rotated the wrist laterally 5-10 degrees |
| A radiograph of an AP oblique-medial rotation reveals the coronoid process is not in profile and the radial head is not superimposed over the ulna. What positioning error was involved? | Insufficient medial rotation |
| A radiograph of a lateral projection of the elbow reveals that the epicondyles are not superimposed and the trochlear notch is not clearly seen. How do you correct this error? | Place the humerus/forearm in same horizontal plane |
