to restore pinch - tendon transfer for ulnar nerve palsy

A

ECRB to adductor policis

or FDS to adductor policis

20
Q

claw deformity transfer

A

FDS to provide flexion fo MCF , keep tendon volar to intermetacarpal ligament

21
Q

fingertip/nailbed injury % that have cold intolerance/hypersensitivity

22

secondary intention can heal what size for tip loss

A

1 cm squared

23
Q

fingertip injury - exposed bone with volar oblique

A

cross finger,
Moberg for thumb
thenar flap for child IF or LF

24
Q

digital island flap

A

can maintain sensory innervation for index or thumb

25
Q

finger tip - dorsal oblique or transverse

A

VY, Kutler, or bone shortening

26
Q

thumb injury

A

<1cm - secondary intension

>1 cm - Moberg, firstst dorsal metacarpal artery kite flap

27
Q

skin graft process

A

plasma imbibition, inosculation, and revascularization

28
Q

boutonnière from what

A

central slip rupture, triangular ligaments ruptured, elson test

29
Q

gap >what is risk for rupture in flexor tendon repair

30
Q

number of core strands needed for early motion in tendon repair

A

4+epitendonous

31
Q

epitendous repair

A

increases strength (by 10-50%) and decreases gap

32

radial height, inclination, tilt

A

11 height
22 inclination
11 tilt

33

stabilizers of DRUJ

A 
RUPERT
radioulnar lig
ulnocarp lig
PQ
ECU 
Radius IOM
TFCC
36
Q

TFCC radiulnar lig

A 
superficial fibers (styloid)
deep fibers (fovea)*** most important
37
Q

acceptable reduction for distal radius fx

A

radial shortening <3 mm
dorsal tilt <10 degrees
articular step off <2mm

38
Q

when would you go dorsal for distal radius fx

A

if also has a SL lig injury

direct visualization of articular surface

39
Q

most common complication after DRF is

A

median nerve dysfunction, needs a release

40

where does blood flow come for scaphoid

A

dorsal ridge

42
Q

operative treatment scaphoid

A

displacement >1mm

proximal pole

43
Q

volar for scaphoid

A

hump back
maintains dorsal blood supply
difficult to get screw centrally

44
Q

dorsal for scaphoid

A

proximal pole fx

vascularized bone graft (1-2 ICSRA)

45
