reciprocal wrist extension/finger flexion grip pattern - answer--scar adhesions
proximal to extensor retinaculum w/ extrinsic extensor tightness and active
fingers flexion cause wrist ext and further wrist ext allows full digit flexion


Innervation Density - answer--2 point discrimination tests this


1.65 - 2.83 - answer--Semmes Weinstein - normal


3.22 - 3.61 - answer--Semmes Weinstein - diminished light touch


3.84 - 4.31 - answer--Semmes Weinstein - diminished protective sensation


4.56 - answer--Semmes Weinstein - loss of protective sensation


6.65 - answer--Semmes Weinstein - los of depp pressure

,Figure 8 edema method - answer--ulnar styloid, cross volar to radial styloid,
diagonal over dorsal hand to 5th MP joint, radial over volar MP joints, return to
ulnar styloid


Kapandji Scale - answer--Thumb Opposition: 0 IF MP -- 1 IF PIP -- 2 IF DIP -- 3 IF P3
-- 4 MF P3 -- 5 RF P3 -- 6 SF P3 -- 7 SF DIP -- 8 SF PIP -- 9 SF MP -- 10 DPC


Neutrophils - answer--predominant cell first 2 days (to phagocytize
debris/bacteria)


Macrophages - answer--2 days after injury (to phagocytize & induce angiogenesis
& create granulation tissue)


Wound maturation (sutured wound) - answer--week 3: 15-25%, 3 months: 50%,
reorganized collagen maximum strength 70-80%


Angiogenesis & neovascularization - answer--new capillaries are forming causing
local erythema (this stage provides the fibroblasts and endothelial cells oxygen &
nutrients)


Hemostasis - answer--Hemostasis lasts 24 hours


Pseudomonas - answer--present in a yellow wound and give color and odor


Autolytic debridement dressing - answer--Hydrogel dressings & hydrocolloid
dressings

,ECU resting position - answer--in supination ECU takes a 30 degree turn and is less
stable (ECU is more stable/better resting position in pronation)


Unopposed adductor pollicis - answer--deforming muscle force in a thumb RCL
injury


Unopposed FPB and APB - answer--deforming muscle force in a thumb UCL injury


IF PIP joint collateral ligament injury - answer--RCL of IF PIP joint more often
injured than UCL of IF PIP Joint


PIP joints more susceptible to injury than DIP/MP joint - answer--PIP joints are
more often injured in extension rather than flexion


Middle finger sagittal band - answer--more injured than other fingers


Maximum differential tendon gliding - answer--hook fist for FDS/FDP; straight fist
for FDS; composite flexion for FDP


Passive protected extension - answer--allows for most distal tendon excursion (3-
8mm)


Most ideal time to start early active mobilization protocol - answer--3-5 days post-
op to let inflammation decrease, but adhesions can start limiting at 1 week post-
op

, Zone 3 flexor tendon repair = distal end of carpal tunnel to the A1 pulley - answer-
-scarring to intrinsics can occur & tightness, so MPs in splint at 30-40 degrees
flexion


Swan-neck deformity - answer--can occur with absent FDS


Normal finger active flexion - answer--PIP joint flexes first


Extensor tendons proximal to juncturae tendinum - answer--ruptures of these can
be missed due to extension through adjacent tendons


Evans' Short Arc Motion extensor tendons - answer--Wrist placed in 30 degrees
flexion, then templates for 30 degrees flexion PIP and 25 degrees flexion DIP, then
advance as no extensor lag present


Extensor tendon repair proximal to JT - answer--all fingers placed in orthosis in
extension


Extensor tendon repair distal to JT - answer--affected digit in full extension,
adjacent digits in 30 degrees MP flexion


Yoke splint - answer--for RF {RF+MF}; for MF {MF}; for SF {SF+IF}; for IF {IF+SF}
