Mallet finger is a common injury that occurs when the tendon responsible for straightening the end joint of a finger is damaged. This results in the fingertip drooping or an inability to straighten it.
There are two types of mallet finger: osseous (involving a bone fragment) and tendinous (affecting just the tendon). Both types require immobilisation, but the treatment duration may vary, and in some cases, surgery could be necessary.
What causes mallet finger?
Mallet finger usually happens when the tip of the finger is forcefully bent, which overstretches or even tears the extensor tendon. This type of injury is common in sports like baseball, basketball, or volleyball when the ball hits the outstretched finger. However, it can also occur from minor incidents, such as tucking in bedsheets or stubbing your finger.
What are the symptoms of mallet finger?
The symptoms of mallet finger are usually quite distinct. Here’s what to look for:
- Drooping finger: The most obvious sign is that the fingertip droops down and cannot be straightened voluntarily.
- Swelling and pain: There may be swelling at the injury site, along with pain and tenderness.
- Bruising: In some cases, bruising may be visible around the affected area.
- Loss of function: Difficulty in extending the finger fully can impact everyday activities, such as typing or gripping objects.
If you notice these symptoms, seeking professional attention promptly is crucial for proper diagnosis and treatment.
At HULC, hand therapists typically diagnose mallet finger through a physical examination and may recommend imaging tests, such as X-rays, to check for fractures or bone involvement. Understanding the severity of the injury helps in formulating an effective treatment plan.
How does hand therapy help mallet finger?
Hand therapy plays a vital role in managing mallet finger. A hand therapist will:
- Create a custom splint to keep the fingertip in the correct position while the tendon heals.
- Teach pain management techniques to alleviate discomfort and closely monitor your progress.
- Regularly assess your condition to adjust the treatment plan as healing progresses, ensuring a personalised approach that optimises recovery and prevents long-term complications.
Treatment options for mallet finger
Treating mallet finger effectively is important to ensure proper healing and restore function.
- Splinting: The primary treatment for mallet finger is splinting. A custom-designed splint by a hand therapist is usually applied to keep the finger in a straight position for about 6 to 8 weeks.
- Surgery: In more severe cases, where there is a fracture or significant tendon injury, surgical intervention may be required to repair the damaged tendon and stabilise the joint.
If you believe you may have mallet finger, it’s important to keep the fingertip in an extended position and seek professional intervention as soon as possible. Early diagnosis and appropriate treatment can prevent complications and improve your chances of a full recovery.
