A finger (or thumb) that won’t straighten, bends the wrong way or looks out of shape can have several different causes. This article explains six common deformities, including mallet finger, swan neck and Dupuytren’s contracture.
Dupuytren’s disease causes lumps or cords to form in the palm that can slowly pull one or more fingers into a bent position. This article explores what causes it, who is at risk and the treatment options.
A finger that stays bent at the middle joint, with the tip bending backwards, can follow an injury to the tendon on top of the finger. This article explains boutonnière deformity, how it develops and how it is treated.
A finger that bends backwards at the middle joint and curls forwards at the tip, like the neck of a swan, is known as swan neck deformity. This article looks at its causes, including arthritis and injury, and how it is managed.
If the tip of your finger droops and you can’t straighten it after a knock to the fingertip, you may have a mallet finger. This article explains what happens to the tendon and why early splinting makes such a difference.
