| AXIAL T2 A2 PULLEY AT MID PORTION OF PROXIMAL PHALYNX 5TH FINGER |
This MRI study of litter finger shows:
Full-thickness flexor digitorum profundus, FDP tendon tear, Zone II injury.
There is associated retraction of the proximal end, spring coiled, the torn end of proximal stump is at the level of metacarpo phalangeal joint, with a gap of 36 mm. Length of the distal stump measuring approximately 20 mm from its insertion on to the base of distal phalanx. Quality of both torn ends of the tendon is good, sharp without abnormal fraying or degeneration.
Associated A2 pulley injury at the level of midportion of proximal phalanx with approximately 4 mm bowstringing of FDS.
A3 pulley intact.
No associated bony avulsion.
No associated joint subluxation.
No associated volar plate injury.
No associated collateral ligaments tear.
