Digit Damage: four common finger injuries
1. Mallet Finger
Mallet finger is usually caused by adirect blow to the tip of the finger, common in sports such as netball. It causes the tendon to rupture from its attachment below the nail. It can be managed with a custom splintthat immobilises the tip of the finger for6-8 weeks. This usually allows the tendonto heal without requiring surgery.
2. Nail Bed or Crush injury
Nail Bed or Crush injury typically occurs when a finger is trapped in a tight space - a door jam for instance. They can often involve bone fracture, skin cuts, tendon, nerve and blood vessel damage.
Treatment includes relieving pressure ofthe bleeding under the nail, compression gloves, wound care and dressings. Scar tissue management also helps to prevent contractures or stiffness that may limit function. Movement can be regained with splints, even several years after the injury.
3. Goalkeeper's Thumb
Goalkeeper's thumb injury, to the baseof the thumb where it meets the palm, is the most common of all ligament tears. It is typically caused by falling on an outstretched hand, and pulling the thumb backwards.
Splinting for 6-8 weeks will usually allow the thumb to heal without the need for surgery. In severe cases where the ligament isruptured, it can be surgically reconstructed.
4. Trigger Finger
Trigger finger is the common name for swelling of the tendons that control finger bending, preventing them from gliding smoothly, and causing pain, popping, or a catching feeling.
Non-surgical treatments are attempted first to reduce the swelling: splints, anti-inflammatory medication, steroid injections, and adjustments in daily activities. If these are unsuccessful, surgery may be recommended.
