⩥Zone 1-3 flexor tendon protocol modified duran. Answer: - Orthosis:
DBS wrist neutral to 20 degrees flex, MPs 70 degrees flex, IPs ext
- 1-2 weeks: Passive flexion/extension isolated PIP/DIP and composite
- 3.5 weeks: active flex/ext in orthosis (may start with place and holds)
- 4.5 weeks: out of orthosis for HEP, wrist/digital AROM (diff tendon
gliding, comp fist with wrist flex/ext, comp wrist/dig flex followed by
wrist/digital ext)
- 6 weeks: D/C orthosis, joint blocking may begin (no SF)
- 8 weeks: light grip strengthening
- 12 weeks: Use hand in all ADLs
- 14-16 weeks: heavy use and gripping
⩥Flexor tendon zones 1-4 delayed mobilization protocol. Answer: -
Orthosis: DBS wrist neutral to 20 degrees flex, MPs 70 degrees flex, IPs
ext
- 3 weeks: PROM in orthosis (PIP/DIP isolated and comp flex) followed
by AROM in orthosis
- 4.5 weeks: HEP out of orthosis
, - 6 weeks: D/C orthosis, begin passive ext, joint blocking
- 8 weeks: Light grip strengthening
- 10-12 weeks hand weights
⩥Flexor tendon repair zones 4-5 protocol. Answer: - Orthosis: DBS
wrist 30 degrees flex, MPs 70 degrees flex, IPs full ext
- 1-2 weeks: Passive composite flex/ext 3-4x per day
- 3 weeks: AROM in orthosis
- 4 weeks: Gentle joint blocking
- 4.5 weeks HEP out of orthosis
- 6 weeks: D/C orthosis, begin passive ext, emphasize differential tendon
gliding
- States at 6 weeks may initiate light strengthening - would start at 8
weeks
- 10-12 weeks: unrestricted use of hand
⩥Early active zone 4-7 extensor tendon protocol. Answer: - Orthosis:
relative motion orthossis (15-20 degrees greater MCP ext relative to
adjacent digits), wrist cock-up in 20-25 degrees extension
- unrestricted AROM of digits with orthoses on
- 3 weeks: D/C wrist cock up
- 6 weeks: D/C relative motion orthosis
If needed: strengthening at 8 weeks post op. Typically do not need
therapy after 6 weeks.
