A tendinopatia é uma das razões mais comuns de visitas a uma clínica especializada em mãos. É mais comum em mulheres, atingindo o pico de incidência aproximadamente na sexta década de vida.[2]Lipscomb PR.

A apresentação mais comum é o dedo em gatilho, seguido pela doença de De Quervain (tendinite do tendão extensor do polegar no primeiro compartimento dorsal). Gestantes e mulheres no pós-parto têm incidência elevada de doença de De Quervain em uma idade mais jovem.[14]Avci S, Yilmaz C, Sayli U.
