What are the treatments for Finger Injuries?
- The fingernail and the underlying nail bed are the most commonly injured part of the hand.
- If a fingernail is injured by a direct blow, the underlying bone may also be broken.
Fractures (broken finger bone)
- Each finger (except the thumb) has three bones, or phalanges: the proximal (closest) phalanx (plural-phalanges), the middle phalanx, and the distal (furthest) phalanx.
- A fracture of a phalanx may be an isolated injury, but it is often associated with injury to tendons, ligaments, fingernails, or other soft tissue.
- A dislocation is an injury to a joint that causes a bone to move out of its normal alignment with another bone.
- Finger dislocations commonly happen as a result of a direct blow to the finger (like while playing ball sports).
- Usually a dislocation causes damage to the surrounding ligaments (ligaments hold bone to bone), which are stretched and remain damaged even after the dislocation is reduced (put back in place).
Ligament injuries (sprains)
- Ligaments are the tough tissues that hold two bones together and stabilize a joint.
- A ligament may be torn by a forceful stretch or blow, leaving the joint unstable and prone to further injury.
- Tendons are the fibrous bands that attach muscles to bones and allow the flexible, precise movements of the joints.
- Tendons lie just under the skin in the fingers and are covered by a protective sheath.
- Both the tendon and its sheath can be damaged by a laceration (cut) or a crush injury.
- A tendon can also be torn away from its bony attachment, which is called an avulsion fracture.
