Trigger finger


The irritation of the flexor tendon causing trigger finger is mostly a consequence of overuse of the hand; however the aetiology of this pathology remains unknown. The condition is more frequent in women and the adult/aged population. Apart from repetitive grasping/gripping function other causes leading to trigger finger include:

Tear to the flexor tendon

Infection of the synovium

Congenital condition predisposing to tendon nodule formation
