AT214: Elbow

The ligament that stabilizes and encircles the head of the radius is the:

Annular Ligament

With the elbow flexed at 45 degrees, the athlete flexes and extends the wrist as far as possible. We are testing for:

Capsular Pain

An injury to the ulnar nerve usually results in parasthesia in the second and third digits.

False

Cubitus varus is an abnormality resulting in an increased carrying angle

False

Pronator teres syndrome involves entrapment of the ulnar nerve.

False

Ten to 25 percent of young pitchers develop little league elbow as a result of the repetitive stress caused by throwing curve balls.

False

The spool-shaped capitulum fits into an articulating groove with the ulna.

False

The triceps bursa is the most frequently injured bursa in the elbow because it is so superficial and at risk for direct trauma.

False

Valgus stress testing of the elbow stresses the lateral collateral ligament of the elbow.

False

Visually observing an elbow at a 45-degree angle of flexion will show the olecranon process and both humeral epicondyles in a straight horizontal line.

False

The motions of the elbow joint are:

Flexion and extension

Which of the following is NOT an elbow flexor?

Flexor Carpi Ulnaris

The adolescent athlete who complains of sudden pain and locking of the elbow joint should be suspected of having:

Osteochondritis Dissecans

Most elbow dislocations result from falling on an outstretched hand and result in the ulna and radius dislocating:

Posteriorly

The motion(s) that occur at the radioulnar joint?

Pronation and supination

Possible complications of a supracondylar humeral fracture are muscle spasm, swelling, or bone pressure on the brachial artery, which inhibit blood circulation to the forearm, wrist, and hand. This is a:

Volkmann's Contracture

Which of the following conditions results from an injury to the brachial artery, usually associated with a supracondylar fracture of the humerus?

Volkmann's Contracture

Which of the following is not a disorder associated with little league elbow?

Cubital Tunnel Syndrome

If resistance is applied to an athlete's extended wrist with the elbow flexed at a 45-degree angle, the athletic trainer is testing for:

Lateral epicondylitis

What nerve innervates the main elbow flexors?

Musculocutaneous

What nerve innervates the main elbow extensors?

Radial

During rehabilitation of a posterior elbow dislocation which of the following phases would include the beginnings of PNF and DAPRE exercises?

Repair Phase

Lateral epicondylitis results from:

Repetitive extension of the wrist

Complications from an elbow dislocation include injury to the median and radial nerve, as well as the brachial artery.

True

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

True

Racquetball elbow, golfer's elbow, and javelin throwers elbow refer to a medial epicondylitis.

True

Restoring normal range of motion is crucial early in elbow rehabilitation

True

Strains to the elbow are usually caused by hyperextension forces

True

The distal end of the humerus forms two condyles: the lateral condyle is called the capitulum, and the medial condyle is called the trochlea.

True

The radial collateral ligament does not attach to the radius, which is free to rotate.

True

Using a tennis racket with an inappropriate grip size can cause added stress to be placed on the elbow.

True

Which nerve can become irritated secondary to cubitus valgus present at the elbow?

Ulnar

If an athlete complains of burning and tingling or paresthesia to the fourth and fifth fingers, what structure may be damaged?

Ulnar nerve
