which of the following mechanisms leads to lateral epicondylitis?

Repetitive forceful extension of the wrist

which structure is most likely damaged when an athlete complains of paresthesia in the fourth and fifth fingers?

Which of the following is true of a Colles' fracture?

Forearm splints are seen most frequently in:

gymnastics

A wrist ganglion is often seen in sports and will most frequently appear:

on the back of the wrist

Severe point tenderness in the anatomic snuffbox may indicate a:

scaphoid fracture

Which of the following treatments would be inappropriate to perform on a suspected phalanx fracture?

Splinting the finger in extension

A deformity caused by jamming and avulsing the extensor tendon from its insertion is called the:

mallet finger.

To ensure the most complete healing of a boutonniere deformity, splinting must be maintained for:

5-8 weeks

Which of the following is the most frequently fractured carpal bone?

The scaphoid bone

What motions occur at the radioulnar joint?

Pronation and supination

Which of the following muscles attach to the lateral epicondyle of the humerus?

Forearm extensors and supinators

Children and young athletes have a higher rate of elbow fracture than do adults.

True

An injury to the ulnar nerve usually results in paresthesia to the second and third fingers.

False

The main symptom of forearm splints is a dull ache between the extensor muscles crossing the back of the forearm.

True

Compression of the median nerve usually results in both sensory and motor deficits

True

Hyperextension forces usually cause sprains to the elbow

true

Pitcher’s elbow, golfer’s elbow, and little league elbow refer to lateral epicondylitits.

False

In medial epicondylitis, passive movement of the wrist seldom elicits pain, although active movement does.

True

The radius, considered an extension of the hand, is thicker at its lower end than at its upper end.

True

A Colles' fracture is a fracture of the proximal end of the radius.

False

the most commonly fractured carpal bone is the hamate

false

When blood accumulates under the nail, it should be iced and the athlete should be sent to a physician immediately.

false

A sprain is the most common wrist injury in sports and often the worst managed.

true

The radial nerve is compressed in an individual who has carpal tunnel syndrome.

false

Care of a collateral sprain includes ice packs for the acute stage, X-ray examination, and splinting.

true
