Chapter 4 Upper Limb

Upper limb

QuestionAnswer
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
