tendon is away from the bone
adhesion formation, fibroblasts and inflammatory cells - ANSWER with extrinsic tendon
healing, ____________ between the tendon and its sheath which prevents gliding of the
tendon, influx of ______________
synovial fluid, tendon ends, peritendinous - ANSWER with intrinsic tendon healing,
_______ diffusion, healing between ________, controlled mobilization to allow healing but
prevent ___________ adhesions
Inflammatory
Fibroblastic
Remodeling - ANSWER phases of tendon healing
Day 0-7 - ANSWER how long does inflammatory phase of tendon healing last?
Day 4-28 - ANSWER how long does the fibroblastic phase of tendon healing last?
4 weeks-1 year - ANSWER how long does the remodeling phase of tendon healing last?
tendon laceration - ANSWER Level of tendon injury is based on relation of the
___________ in the sheath when the finger is fully extended
Block PIP joint in extension, and have patient bend DIP joint - ANSWER how to assess
FDP
Supinate forearm and hold all digits except one being tested. Bend PIP of untethered
digit toward palm to assess motion - ANSWER how to assess FDS
,extends from insertion of FDS at middle phalanx to that of the FDP at the distal phalanx. -
ANSWER flexor zone 1
FDP, DIP, PIP - ANSWER in flexor zone 1, _____ is injured; loses ____ flexion but
maintains _____ flexion
jersey finger - ANSWER a Zone I flexor tendon injury, common with the football athlete,
refers to an avulsion injury of FDP from insertion at base of distal phalanx, FDP muscle
belly in maximal contraction during forceful DIP extension
Ring finger involved in 75% of cases, during grip ring fingertip is 5 mm more prominent
than other digits in ~90% of patients, therefore ring finger exposed to greater average
force than other fingers during pull-away, finger lies in slight extension relative to other
fingers in resting position
flexor zone 2 - ANSWER "No Man's Land"- awful area to injure, Region where both FDS
and FDP travel within the flexor sheath from the A1 pulley to the insertion of the FDS
from A1 pulley to the insertion of FDS - ANSWER Flexor zone 2
between the distal border of the carpal tunnel and A1 pulley of the flexor sheath -
ANSWER flexor zone 3
tendons and digital nerve - ANSWER in flexor zone 3, May see both _______ injury here.
Good prognosis because this is out of sheath area and not as much scarring occurs -
ANSWER does flexor zone 3 have good or bad prognosis?
within the carpal tunnel area - ANSWER flexor zone 4
median and ulnar nerves, ulnar artery and superficial palmar arch - ANSWER injury that
occurs in flexor zone 4
no - ANSWER are flexor zone 4 injuries common?
extends from the flexor musculotendonous junction in the forearm to the proximal
border of the transverse carpal ligament. - ANSWER flexor zone 5
nerves, tendons, arteries - ANSWER in flexor zone 5, Deep forearm lacerations may
involve _________
FDP, artery, DN, fx? - ANSWER structures affected in flexor zone 1
Sheath, 2 tendons, vincula, DN - ANSWER structures affected in flexor zone 2
Palmar aponeurosis pulley, proper digital nerves, palmar arch, arteries, 2 tendons -
ANSWER structures affected in flexor zone 3
, TCL, Tendons, MN + motor branch - ANSWER structures affected in flexor zone 4
Multiple tendons, MN/UN, radial and ulnar artery, "Spaghetti wrist" - ANSWER
structures affected in flexor zone 5
DBS- dorsal blocked splint
Wrist flexed to 20-45 degrees?
MCP flexed 40-90 degrees?
PIP's and DIP's in neutral (0°).
splinting
No precautions after 12 weeks of healing - ANSWER rehab of flexor tendon injuries
12 - ANSWER for rehab of flexor tendon injuries- no precautions after ___ weeks of
healing
wrist and finger extension, finger flexion - ANSWER we splint with flexor tendon injuries
because it protects healing tendon by preventing excessive stretch from combined
_____________, and preventing excessive stress from strong active _________
tenodesis - ANSWER when bring wrist back, fingers should curl up, splint allows this
motion, getting them into functional movements
Kleinert, modified duran, indiana, chow - ANSWER protocols used with flexor tendon
injuries
modified duran and indiana - ANSWER protocols used the most
cruciate pulleys - ANSWER function to prevent sheath collapse and expansion during
digital motion, 3 total at the level of the joints
