Q

Describe process of gripping

A

Open hand- extensors and abductors contract concentrically
Take hold- flexors and abductors contract concentrically
Hold- flexors and abductors work isometrically
Letting go- flexors and abductors contract concentrically

Q

Wrist joint

A

Radiocarpal joint- distal end of radius articulates with proximal row of carpal bones
Ulna does not directly articulate with carpal bones due to soft tissue structures between them
However ulnocarpal joint does transmit 20% of load from hand to forearm when compression forces occur through the wrist

16
Q

Motion at radiocarpal and midcarpal joints

A 
Flexion and extension of the hand 
Flexion greater at radiocarpal joint
Extension greater at midcarpal joint
Radial and ulnar deviation
Radial deviation greater at midcarpal joint
17
Q

Why is radial deviation limited?

A

Due to the impingement of the carpus against the styloid process of the radius
Ulnar deviation not as limited as the styloid process of the ulna is located posteriorly

18
Q

Radioulnar disc

A

Also known as triangular fibrocartilage

Adds stability to radiocarpal joint

19
Q

Transverse carpal ligament

A

forms roof of carpal tunnel
encloses and stabilises carpal tunnel
also functions as a retinaculum for the extrinsic finger flexor muscles of the forearm

20
Q

Extrinsic ligaments

A

Attach onto forearm bone/s and attach distally onto carpal bones
stabilize the radiocarpal joint
Dorsal radiocarpal ligament, palmar radiocarpal ligament, radial collateral ligament and ulnar collateral ligament

21
Q

Dorsal radiocarpal ligament

A

located posterior side from radius to carpal bones

limits full flexion

22
Q

Palmar radiocarpal ligament

A

involves 3 ligaments
located anterior side from radius to carpal bones
limits full extension

23
Q

Radial collateral ligament

A

located from radius to carpal bones

limits ulnar deviation

24
Q

Ulnar collateral ligament

A

located from ulnar to carpal bones

limits radial deviation

25
Q

Intrinsic ligaments

A

attach proximally and distally onto carpal bones
stabilize motion between carpal bones at the midcarpal joint
divided into short, intermediate and long ligaments

26
Q

Short ligaments

A

connect distal row of carpal bones to each other

27
Q

Intermediate ligaments

A

connect proximal row of carpal bones to each other

28
Q

Long ligaments

A

connect scaphoid, triquetrum and capitate

29
Q

Closed pack position of wrist joint

A

extension and slight ulnar deviation

30
Q

Carpometacarpal (CMC) ligaments

A

dorsal, palmar and interosseous CMC ligaments

Stabilize CMC joint

31
Q

Thumb joint

A

Saddle joint

Located between trapezium and first metacarpal

32
Q

What is basilar arthritis?

A

arthritis of the thumb saddle joint
