Q

triquetral

Study These Flashcards
A
  • pinchable border, tubercle faces in direction its from
22
Q

pisiform

Study These Flashcards
A
  • pea shaped
  • articulates with triquetral
  • surrounded by tendons
  • no siding
23
Q

trapezium

Study These Flashcards
A
  • rhymes with thumb
  • saddle shaped
24
Q

trapezoid

25
capitate
- keystone of the wrist - many central articulations - round part is the head, longer part is the ponytail
26
hamate
lots of articulations
27
carpal tunnel
- roof of the carpal tunnel runs across the trapezium and hamate - all flexors run through this - pathology gets its name from the overwear of this area
28
metacarpals
- flat, convex on dorsal view and curved, concave view on the palmar view - focus on the base - head articulates with proximal phalanx - base articulates with carpals
29
MC1
- short, stout, saddle - not narrow, no expansion of ends - end compliments the saddle in the trapezium
30
MC2
- long - sloppy W on proximal end
31
MC3
- lateral styloid process
32
MC4
- square base
33
MC5
- no articular facet medially
34
side MC1
- most lateral - medial side is shorter
35
side MC2
- largest wedge is medial - facet faces towards MC1 - laterally
36
side MC3
- styloid process is lateral
37
side MC4
- double facet is lateral - single facet is medial
38
side MC5
- single facet is lateral - medial side has no facet
39
mobility of radiocarpal joints
circumduction
40
mobility of midcarpal joints
very limited
41
mobility of carpometacarpal joint
limited except with CMC1
42
mobility of metacarpophalangeal joint
some circumduction
43
interphalangeal joint movement
flexion and extension only
44
scaphoid articulations
capitate radius lunate trapezium
45
lunate articulations
capitate radius scaphoid triquetral hamate
46
triquetral articulations
pisiform hamate lunate
47
