*****Bones of the Hand + Palpate (Examine) Them

palmar/volar side

palm up

dorsal side

palm down

__ carpal bones

8

the 8 carpal bones are split into 2 rows…

• 4 in proximal row

• 4 in distal row

__ metacarpals

5

__ forearms bones; __ and __; __ is on the thumb side

2; radius and ulna; radius (“Radius is rad” —> thumbs up)

pisiform (palmar/volar side)

• on proximal (closer to trunk) ulnar side

• sits on top of the triquetrum

pisiform (palpating)

bony landmark in palpation

pisiform (dorsal side)

not visible on the dorsal side, as it is now “under” the triquetrum, as opposed to when sitting on top of it on the palmar side

triquetrum (palmar/volar side)

sits right under the pisiform

triquetrum (palpating)

sits right under the pisiform

triquetrum (dorsal side)

can see this clearly, as it is over the pisiform on the dorsal side

hamate (palmar/volar side)

from the pisiform, move radially and distally

hamate (palpating)

• from the pisiform, move radially and distally

• may feel a little tender

• bump

hamate (dorsal side)

trapezium (palmar/volar side)

found at the end of the 1st metacarpal

trapezium (palpating)

start from the end of the 1st metacarpal, then slide down until you reach a divot

trapezium (dorsal side)

at the base of 1st metacarpal

scaphoid (palmar/volar side)

feel for a baby bump

scaphoid (palpating)

• palpate for the trapezium (find end of 1st metacarpal, and slide down until you reach a divot)

  • draw proximal a bit

    • then a little ulnar

scaphoid (dorsal side)

lunate (palmar/volar side)

in between scaphoid and triquetrum

lunate (palpating)

• find pisiform bump

• find scaphoid bump

• it’ll be somewhere in the middle

lunate (dorsal side)

trapezoid (palmar/volar side)

next to trapezium

trapezoid (palpating)

slide down from the 2nd metacarpal until you reach a divot

trapezoid (dorsal side)

trapezoid (palmar/volar side)

capitate (palmar/volar side)

capitate (palpating)

• articulates with the 3rd metacarpal (which comes down from the middle finger)

  • slide down until you reach a divot

capitate (dorsal side)

how to remember (palmar/volar side)

• from left to right + proximal to distal, “Some Lovers Try Positions That They Can’t Handle”

  • scaphoid —> lunate —> triquetrum —> pisiform —> trapezium —> trapezoid —> capitate —> hamate

how to remember (dorsal side)

• go in the opposite direction of the palmar/volar side, but keep the phrase the same “Some Lovers Try Positions That They Can’t Handle”

  • scaphoid —> lunate —> triquetrum —> pisiform —> trapezium —> trapezoid —> capitate —> hamate

1st metacarpal articulates with the __

trapezium

2nd metacarpal articulates with the __

trapezoid

3rd metacarpal articulates with the __

capitate

4th metacarpal articulates with the __

hamate

5th metacarpal articulates with the __

hamate

thumb phalanx

proximal, distal

finger phalanx

proximal, middle, distal

distal phalanx

tip to crease

middle phalanx

crease to crease
