Flexor Tendon CHT 2025/2026 Exam
Questions and Answers 100%
Guaranteed Success | Already Rated A+
Strickland Formula - 🧠 ANSWER ✔✔Active PIP + DIP flexion - extension
lag x °
= % of normal active PIP and DIP motion
Excellent: 85-100%
Good: 70-84%
Fair: 50-69%
Poor: <50%
Trigger Finger Stages - 🧠 ANSWER ✔✔Stage 1 Palm pain and tenderness
@ A1 Pulley
,Stage 2 Catching of Digit
Stage 3 Locking of Digit, Passively Correctable
Stage 4 Fixed Locked Digit
Flexor Tendon Healing Phases - 🧠 ANSWER ✔✔Inflammatory phase - 48-
72 hours
Fibroblastic phase - 4 days through 5 weeks
Remodeling phase - Through 112 days
Tendon Tensile Strength - 🧠 ANSWER ✔✔Decreases during the first week
following a repair
Mason & Allen, 1941
Progressive increase after the first 2-3 weeks
Increase in strength proportional to the amount of stress provided
Immediate controlled stress to the healing tendon facilitates a reversal of
the initialweakening process
• Maximum collagen synthesis occurs at 3 weeks
Annular Pulleys - 🧠 ANSWER ✔✔A1 .5 cm prox to MP jt and anchored to
VP and prox phalanx
, A2 Immediately distal to A1, extends 1/2 length prox phalanx, largest
annular pulley - critical - prevent bowstrining
A3 Arises from PIP and anchored to VP at PIP jt
A4 Arises from middle 1/3 of middle phalanx - critical bowstring
A5 Thickening of sheath over DIP arising from VP
Transverse Carpal Lig acts as pulley - preventing bowtstinging @ wrist
Cruciate Pulleys - 🧠 ANSWER ✔✔C1 between A1 and A3 pulleys
C2 between A3 and A4 pulleys
C3 distal to A4 pulley
Thumb Pulleys - 🧠 ANSWER ✔✔Annular Pulleys located @ MP and IP jts
Oblique pulley between 2 annular pulleys over prox phalanx
Oblique pulley most impt for mech efficiency of FPL
Flexor Tendon Zones - 🧠 ANSWER ✔✔Z I from I of FDS on middle
phalanx. Only FDP
Z II Beg of A1 pulley just prox to MP jt extending to FDS insertion. Includes
area of flexor tendons within pulley system
