How do you fix a swan neck deformity on your finger?

Which tendon is affected in boutonniere deformity?
Boutonnière deformity is generally caused by a forceful blow to the top (dorsal) side of a bent (flexed) middle joint of a finger. It also can be caused by a cut on the top of the finger, which can sever the central slip (tendon) from its attachment to the bone.
Which tendon is involved with mallet finger?
In a mallet injury, when an object hits the tip of the finger or thumb, the force of the blow tears the extensor tendon. Occasionally, a minor force such as tucking in a bed sheet will cause a mallet finger.
What is damaged in swan neck deformity?
The usual cause of a swan neck deformity is weakness or tearing of a ligament on the palm side of the middle joint of the finger. Sometimes it is caused by tearing of the tendon that flexes the middle joint. In other cases, injury of the tendon that straightens the end joint is the cause.
Can swan neck deformity be reversed?

How does mallet finger lead to swan neck deformity?
Mallet finger leads to an imbalance in the distribution of the extensor force between the proximal interphalangeal (PIP) and DIP joints. If left untreated, mallet finger leads to a swan neck deformity from PIP joint hyper extension and DIP joint flexion.
What joint gets injured in a jersey finger injury?
Jersey finger (rugby finger) is an avulsion of the flexor digitorum profundus tendon (FDP) from its distal insertion on the distal phalanx (zone I). The ring finger is most commonly affected.

In swan-neck deformity, the joint at the base of the finger bends in (flexes), the middle joint straightens out (extends), and the outermost joint bends in (flexes). In boutonnière deformity, the middle finger joint is bent inward (toward the palm), and the outermost finger joint is bent outward (away from the palm).
Where are the tendons on your fingers?
The flexor tendons run along the palm side of the fingers and are very close to the surface of the skin, particularly where the skin folds as you bend your fingers. The extensor tendons run along the back side (not the palm side) of your fingers and are also very close to the skin.
What is a Seymour fracture?
Seymour fractures are open, displaced juxta-epiphyseal fractures of the distal phalanx, with an overlying nail bed laceration that occur in children and adolescents with an open physis. This fracture occurs rarely, but its potential consequences are clinically significant.
