Pollex flexus congenitus

| ICD-10 online (WHO version 2019) | |
For small children a congenital variant comes fast fingers on the thumb before that Pollex flexus congenital (congenital curved thumb) is called. In this case, the thumb on the distal phalanx is in a flexed position and cannot be actively stretched.
This change is innate, but usually only becomes apparent after several weeks, months or later.
The cause is a disturbance in the passage of the flexor tendon through the ring ligaments, which hold the tendon in place. There is a nodular thickening in the tendon so that sliding is no longer possible. A corresponding thickening of tissue can be palpable on the flexor side in the base joint, a so-called "Notta'scher knot".
Treatment consists of cutting the blocking ring ligament in the first few years of life.
