28
Q

How does an athlete injure the TFCC?

A

Most often injured when swinging a bat or a racket that creates a violent twist, or torque of the wrist

29
Q

Symptoms and signs of an injured TFCC?

A

Pain along the ulnar side of the wrist. Wrist extension is difficult and painful, especially on the ulnar side of the wrist. There is considerable swelling around the wrist.

30
Q

How does one manage an TFCC injury?

A

Patient should be referred to a physician for treatment. If not properly managed permanent loss of motion and disability can occur. The wrist should be immobilized for 4 weeks followed by motion and strength exercises.

31
Q

Wrist tenosynovitis occurs to which muscle?

A

the extensor carpi radialis longs or brevis

32
Q

How does wrist tenosynovitis occur?

A

movements that require the patient to perform repetitive wrist acceleration and decelerations. The repetitive use and overuse of the wrist tendons and their sheaths.

33
Q

symptoms and signs of wrist tenosynovitis?

A

pain with use or pain in passive stretching. There is tenderness and swelling over the tendon.

34
Q

management of wrist tenosynovitis?

A

acute pain and inflammation are managed by ice massage for 10 minutes four times a day for the first 48 to 72 hours.

35
Q

What is the primary cause of tendinitis?

A

overuse of the wrist.

36
Q

What are the two most common nerve entrapments of the wrist?

A

the median nerve and the ulnar nerve

37
Q

How does nerve palsy occur?

A

by direct trauma to a nerve

38
Q

What nerves are most likely to exhibit nerve palsy?

A

the median and radial nerves

39
Q

Benediction/Bishop’s deformity results from?

A

a damage to the ulnar nerve that affects the hypothenar and intrinsic muscles of the ring and little fingers.

40
Q

How does drop wrist deformity occur?

A

A palsy of the radial nerve

41
Q

How does Claw Hand deformity occur?

A

Compression of both the median and ulnar nerves

42
Q

What is deQuervain’s syndrome?

A

A stenosing tenosynovitis in the thumb. Also called Hoffman’s disease.

43
Q

Signs and symptoms of deQuervain’s syndrome?

A

A positive Finkelstein’s test. Point tenderness and weakness during thumb extension and abduction, and there may be a painful snapping and catching to the tendons during movement.

44
Q

What is Kienbock’s disease?

A

a loss of blood supply to the lunate bone, eventually resulting in osteonecrosis. The cause of Kienbock’s disease is unknown. Patient thinks he or she has a sprained wrist

45
Q

symptoms and signs of Kienbock’s disease?

A

as the disease progresses, the patient may develop a painful and sometimes swollen wrist, limited range of motion in the affected wrist, decreased grip strength in the hand, tenderness directly over the bone and pain or difficulty in turning the hand upward.

46
Q

treatment of Kienbock’s disease?

A

usually immobilization with a cast and the use of NSAIDS.

47
Q

What is the most frequently fractured of the carpal bones?

A

the scaphoid

48
Q

how does scaphoid fracture occur?

A

usually by a force on the outstretched hand.

49
Q

What is Preiser’s disease?

A

Avascular necrosis of the scaphoid bone due to the unhealing of a scaphoid fracture

50
Q

signs and symptoms of Preiser’s disease?

A

Swelling in the area of the carpal bones, severe point tenderness of the scaphoid bone in the anatomical snuffbox. Absence of the ability to provoke pain by applying pressure in the anatomical snuffbox is perhaps the best way to distinguish a scaphoid fracture from a wrist sprain.

51
Q

What is a wrist ganglion?

A

A synovial cyst often seen in sports.

52
Q

symptoms and signs of a wrist ganglion?

A

Patient pains of occasional pain with a lump at the site. Pain increases with use. There is a cystic structure that may feel soft, rubbery, or very hard.

Q

What is the cause of Trigger Finger/Thumb

A

Nonspecific overuse

57
Q

Another name for mallet finger

A

Baseball finger or basketball finger

58
Q

What is the correct term for Mallet Finger?

A

Extensor Tendon Avulsion

59
Q

What is Mallet Finger caused by?

A

A blow from an object that strikes the tip of the finger, jamming and avulsing the extensor tendon from its insertion, along with a piece of bone.

60
Q

Signs and symptoms of Mallet Finger?

A

The patient is unable to extend the finger, carrying it at approximately a 30-degree angle.

61
Q

What is Boutonniere Deformity?

A

A rupture of the extensor tendon dorsal to the middle phalanx.

62
Q

Symptoms and signs of Boutonniere Deformity?

A

Patient complains of severe pain and an inability to extend the DIP joint. There is swelling, point tenderness and an obvious deformity.

63
Q

Management of Boutonniere Deformity?

A

Cold application followed by splinting of the PIP joint in extension.

64
Q

What is the correct term for Jersey finger?

A

Flexor Digitorum Profundus Rupture

65
Q

What is the cause of Dupuytren’s contracture?

A

The cause is unknown. Nodules develop in the palmar aponeurosis that limit finger extension and eventually cause a flexion deformity.

66
Q

Symptoms and signs of Dupuytren’s Contracture?

A

A flexion deformity most often develops in which the ring or little finger moves into the palm of the hand and cannot be extended.
