Q

radiocarpal joint- triangluar fibrocartliage complex

A

complex of ligaments and catliage
- distal radioulnar joint articular disc
- ligaments
functions:
- stabilise distal radioulnar joint
- transmitt and distrubute load form carpals to ulna
- helps to facilitate complex wrist movment

16
Q

intercarpal joints classification

A

synovial multiaxial plane
allow small gliding movments

17
Q

scapholunate ligament

A

function is to prevent the schapoid and the lunate bone from dislocating

18
Q

carpometacarpal joint of the thumb classification

A

synoival biaxial saddle

does flexion, extension ABD ADD circumduction and opposition. these occur in oposite planes and opposite axis

19
Q

carpometacarpal joint of the thumb articular surfacd

A

trapezium & base of 1st metatrsal

20
Q

carpometacarpal joint of the digits 2-5 classification

A

synovial, multiaxial, plane

21
Q

palmer carpometacarpal ligament

A

from distal row of carpal bones to bases of metacarpals 2-5 on anterior side

22
Q

dorsal carpometacarpal ligament

A

from distal row of carpal bones to bases of metacarpals 2-5 on posterior side

23
Q

metacarpophalangeal joint classification

A

synovial biaxial condyloid

24
Q

metacarpophanlangeal ligaments

A

thinkening of articular sides
funtion:
- limit flexion of digit
- prevent abduction and adduction of digits in flexion

25
Q

palmar ligaments (plates)

A

fibrocartligionus plates
form part of articular surfaces
grooved for long flexor tendon
limit extension of digits

26
Q

deep transverse metacarpal ligaments

A

connect palmar ligaments of MCP joints 2-5 (keep heads together)

27
Q

interphalangeal joints

A

synovial uniaxial hinge

28
Q

IP joint collatersl ligaments

A

thickening of articular capsule and function to limit flexion of digit

29
Q

IP joint palmer plates

A

limit extension of digits
