This pathology of the hand is one of the most frequent and most unrecognized. It reflects a conflict between the deep flexor tendon and a digital pulley (pulley A1).
This conflict causes pain when fingers block in flexion. The blockage is due to the inflame at the level of the tendon causing a pull when passing through the pulley.
There are three stages of inctreasing severity :
- Stage1 : Isolated pain at the base of the finger, no blockage is felt
- Stage 2 : painful, sporadic blockage, mainly in the morning
- Stage 3 : permanent blockage requiring the other hand to « have the finger back to its position ».
