The tendon that bends the finger no longer glides smoothly through a tight pulley in the palm called the A1 pulley. The thumb, ring, and middle fingers are affected most often.
Warning signs
- A finger that catches or snaps when you move it
- A tender bump in the palm at the base of the finger
- Worse in the morning or after gripping
- A finger that locks bent and has to be pulled straight
Treatment
Mild cases often respond to a night splint and a single corticosteroid injection. Persistent locking is treated with a short outpatient release of the A1 pulley under local anesthesia, and patients typically use the hand the same day.

En español: ¿Se le traba, brinca o se queda doblado un dedo?
El tendón que dobla el dedo ya no se desliza bien por una polea estrecha en la palma (la polea A1). El pulgar, el anular y el dedo medio son los más afectados.
Señales de alerta
- El dedo se traba o brinca al moverlo
- Un bulto sensible en la palma, en la base del dedo
- Peor por la mañana o después de agarrar con fuerza
- El dedo se queda doblado y hay que enderezarlo con la otra mano
Tratamiento
Los casos leves suelen mejorar con una férula nocturna y una inyección de corticoide. Cuando el dedo sigue trabándose, se realiza una liberación corta y ambulatoria de la polea A1 con anestesia local; la mayoría usa la mano el mismo día.
