Swan neck deformity has many of possible causes arising from the DIP, PIP, or even the MCP joints. In all cases, there is a stretching of the volar plate at the PIP joint to allow hyperextension, plus some damage to the attachment of the extensor tendon to the base of the distal phalanx that produces a hyperflexed mallet finger.
If patients do have median nerve palsy, occupational therapy or wearing a splint can help reduce the pain and further damage. Wearing a dynamic splint, which pulls the thumb into opposition, will help prevent an excess in deformity. This splint can also assist in function and help the fingers flex towards the thumb.
Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away (PIP flexion with DIP hyperextension).

Buddy wrapping, also called neighbour strapping [1] or buddy taping, is the act of bandaging a damaged or particularly a fractured finger or toe together with a healthy, uninjured one. The bandage or medical tape is usually stiff, not allowing the digits to move; the healthy digit acts as a splint , keeping the damaged one in a natural position ...
Dislocations can be categorized based on the direction that the fingertip moves in relation to the knuckle. [6] If in the direction of the palm, it is a volar dislocation. If in the direction of the back of the hand, it is a dorsal dislocation. [6] If in the direction to either side, it is a lateral dislocation. [2]
Fracture of the tuft of the finger. Finger injuries are usually diagnosed with x-ray and can get to be considerably painful. The majority of finger injuries can be dealt with conservative care and splints. However, if the bone presents an abnormal angularity or if it is displaced, one may need surgery and pins to hold the bones in place.
A finger contracture caused by Dupuytren's contracture. Muscle contractures can occur for many reasons, such as paralysis , muscular atrophy , and forms of muscular dystrophy . Fundamentally, the muscle and its tendons shorten, resulting in reduced flexibility.
