trapezoid

25
Q

capitate

A
  • keystone of the wrist
  • many central articulations
  • round part is the head, longer part is the ponytail
26
Q

hamate

A

lots of articulations

27
Q

carpal tunnel

A
  • roof of the carpal tunnel runs across the trapezium and hamate

  • most lateral
  • medial side is shorter
35
Q

side MC2

A
  • largest wedge is medial
  • facet faces towards MC1 - laterally
36
Q

side MC3

A
  • styloid process is lateral
37
Q

side MC4
