Q

how will the injury look if it occurs when the finger is flexed?

A

tendon injury will be distal to wound, FDP will be lacerated on a different level than the FDS due to different excursion

Q

symptoms of a flexor tendon injury

21
Q

late phase of tendon healing

A

6+ weeks
continued gain of tensile strength
at 12 weeks enough tensile strength for most functional activities

22
Q

a 3mm gap can cause a repaired tendon to

A

fail to glide or rupture due to catching on pulley edge

23
Q

3 basic protocols for a flexor tendon repair

A

immobilization (3-4 weeks)
early passive motion (within 24 hours of repair)
early active motion (within a few days of repair)

24
Q

immobilization protocol for orthosis position

A

wrist flexed 20-30 degrees
MCPs flexed 50-60 degrees
IPs straight

25
how does the immobilization change for a flexor tendon repair in the intermediate phase of healing?
move wrist to a neutral positon
26
when in the intermediate phase of healing from a tendon flexor repair do you wear the orthosis when doing exercises?
No, remove during exercise
27
for early active motion protocol for a flexor tendon repair what orthosis is worn and for how long
a wrist tenodesis orthosis and wrist dorsal blocking orthosis up to 6 weeks
28
kleinert Protocol
passive flexion with rubber bands and active extension in DBS 0-4 weeks: DBS, passive flexion, active extension 4-6 weeks: wristlet, place and hold excercises, scar management 6-8 weeks: AROM, TGEs, differiental gliding, and light ADLs 8-12 weeks: strengthening, work/leisure activities
29
durant protocol
passive flexion and extension in DBS 0-4.5 weeks: DBS, passive flexion and extension 4.5-6 weeks: active flexion and extension in DBS 6-8 weeks: TGEs, diff gliding, scar management, light ADLs 8-12 weeks: strengthening and work/leisure activites
30
the groths pyramid of progressive force application is a guide for progression when adhesions limit...
active flexion
31
start with exercises that result in __ force to the tendon repair
least
32
when is frequency of exercise using the groths pyrmaid higher?
at base of pyramid, decreases at pt moves up
33
if patient has good early active motion delay what type of exercise?
resistance
34
no grip or pinch strength testing till what week?
week 12
35
what modality can be used to decrease adhesions
ultrasound
36
when should you being NMES
within 1 week of resistance exercise
37
Duran and Houser's passive exersies protocol and what mm to promote optimal excursion to decrease adhesion formation
6-8 reps 2x per day 3-5mm
38
pyramid order
bottom to top: passive protected extension palce and hold active composite fist stright and hook fist isolated jt movements discontinue splint reistive comp fist resitive hook and strgiht fist resistive isloated jt movements
39
extensor tendons are ___ and ___ compared to flexor tendons
broad and thin
40
extensors are __ compared to flexors
weak
41
extensors are more ___ and do not run under a ____ system like the flexors do
superficial; pulley
42
the juncturae tendinum is an ___ tendon/ a narrow band of CT interconnecting the ___ tendons
interconnecting; EDC
43
functions of the JT?
force distribution maintain space for the EDC tendons during digit extension MCP stabilization
44
extensors can funtion at ___ weeks versus 12 weeks like the flexors
6-8 weeks
45
3 basic extensor tendon rehab appraoches based on zones
immobiliztion for zone 1 or 2 early passive or active for zone 3-7
46
zone 1 injury also known as a ___ ___ spint this is slight ___ for how many weeks? and then after these weeks what do you limit?
mallet finger HE 6-8 weeks limit DIP flexion to 20-25 degrees
47
no full ___ after a zone 1 injury until 3 months post
flexion
48
zone 5 and 6 injuries are mainly due to what
laceration or rupture due to RA
49

non gliding tendon adhesions
50
post op week 1
