Hand & Finger Injuries

Hand and finger injuries

Injuries to the hand and fingers are common in sports and must be taken seriously. Here we explain sudden onset (acute) injuries as well as chronic (overuse) hand and finger injuries.


Sudden onset sprains, strains & fractures

Sudden onset injuries are known as acute injuries and are usually caused by direct trauma. They include ligament sprains, tendon strains, and fractures. Acute injuries can become chronic if they are not treated properly.

Sprained finger

A finger sprain is a tear or stretching of any of the ligaments which connect the finger bones. It occurs when the finger is bent in some way.

Symptoms include:

  • Sudden pain
  • Swelling
  • Tenderness which presses over the injured ligament
  • Difficulty moving your finger

Thumb sprain

Thumb sprain

A sprained thumb occurs when the thumb is bent out of its normal range of movement, usually backwards. It can happen in sports like skiing, rugby, and basketball and causes pain and swelling.

The ligaments supporting the joint at the bottom of the thumb get damaged, and this can be helped by taping, icing, and compression.

Finger fracture

Broken finger

A broken finger is a break or fracture in any one of the 3 small phalange bones which make up each finger. Finger fractures are usually caused by some kind of impact or collision.

Symptoms include:

  • You will feel immediate pain with swelling and bruising, which will appear quite quickly.
  • It will be painful to try and move your finger, which may appear deformed.
  • If there is any nerve damage, the finger may be numb or feel tingly.

Dislocated finger

Dislocated Finger

A dislocated finger occurs when two of the finger bones forming joints become displaced, injuring the ligaments and other soft tissue in the process.

Symptoms include:

  • Immediate pain with an obvious deformity of the finger
  • The patient will have great difficulty trying to move the finger
  • It is likely to swell up quickly and bruising may appear later
  • If there is any nerve damage then the dislocated finger may feel numb or tingly
  • Damage to blood vessels could result in the skin feeling cold and appearing pale

Volar plate injury

The volar plate is a very thick ligament which joins two bones in the finger.

A volar plate injury occurs when the finger is bent too far back the wrong way, spraining or tearing the ligament. In some cases, this can also involve a fracture.

Bruised hand

Also known as a hand contusion, occurs due to a direct trauma of the hand. Impacts and crush injuries are the most common causes. This hand injury usually results in bleeding and subsequent bruising and will be painful to touch. Rest and ice are two of the main ways to help this injury.

Gradual onset & chronic hand and finger injuries

Chronic injuries develop over time, usually through overuse. A chronic hand or finger injury can flare up like an acute injury if it is not rested and treated correctly.

Dupuytren’s contracture

Dupuytren’s contracture is a condition which affects the hand and fingers, causing the fingers to bend in towards the palm of the hand. Tissue in the hand contracts and becomes shorter, although this does not normally cause pain. Many cases do not require treatment, although if the condition is severe, there are options you can take.
