Mallet finger: Causes, symptoms, treatment, and recovery
Understanding mallet finger
Mallet finger, also known as baseball finger or dropped finger, is a common hand injury that affects the extensor tendon in the finger. This tendon straightens the finger's last joint, the distal interphalangeal joint (DIP joint). When the extensor tendon is damaged or torn, it can result in the inability to extend or straighten the finger fully. Sometimes, a piece of bone is pulled off with the tendon, known as a bony mallet finger.
Causes of mallet finger
Mallet finger is typically caused by an abrupt force or trauma to the finger. Common causes include:
Sports injuries: Mallet finger is frequently seen in baseball, basketball, and volleyball when the ball strikes the fingertip forcefully.
Accidental injury: Jamming or forcefully bending the finger can cause a mallet finger.
Symptoms of mallet finger
The most prominent symptom of a mallet finger is the inability to straighten the affected finger at the DIP joint fully. Other common signs and symptoms include:
Appearance: The finger may be drooped at the end of the joint.
Pain: Pain around the DIP joint of the injured finger.
Swelling: Swelling at the fingertip where the injury occurred.
Bruising: Discoloration or bruising around the injured area.
Weakness: Reduced strength in the affected finger.
Tenderness: Tenderness or pain when touching the injured area.
Treatment for mallet finger
The treatment for a mallet finger typically depends on the severity of the injury. Common approaches include:
Consult with an expert: An Accredited Hand Therapist is a physiotherapist or occupational therapist with expertise in the finger, hand, wrist, elbow, and shoulder.
Splinting: The most common treatment for mallet finger is to wear a splint that immobilises the DIP joint in an extended position. This allows the torn tendon or bone fragment to heal properly. Splinting is usually required for several weeks, and it's essential to wear it consistently.
Surgery: In severe cases or if the bone is fractured along with the tendon injury, surgical intervention may be necessary to repair the damage.
Medication: Over-the-counter pain relievers may be recommended to manage discomfort during the healing process.
Recovery and rehabilitation
The recovery period for a mallet finger can vary depending on the severity of the injury and the chosen treatment approach. Here are some essential points to consider during the recovery process:
Follow advice: Adhere to the treatment plan recommended by your Accredited Hand Therapist. This may include wearing the orthosis consistently and attending follow-up appointments.
Rehabilitation exercises: Engage in exercises prescribed by an Accredited Hand Therapist to regain strength and flexibility in the injured finger.
Protect the finger: Avoid activities that could re-injure the finger during healing. It's crucial to protect the finger and prevent further trauma.
Monitor progress: Keep an eye on your finger's progress during healing. If you notice any unusual symptoms or concerns, communicate with them promptly with your healthcare provider.
Patience: Recovery from a mallet finger can take time. Be patient and allow the injured finger to heal properly.
