• Compression: Using an elastic bandage or compression wrap can help control swelling.
• Elevation: Keeping the hand elevated above heart level can further reduce swelling.

4. Pain Management

• Over-the-counter pain relievers such as nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help manage pain and inflammation.

5. Physical Therapy

• Once the acute pain subsides, physical therapy may be recommended to restore strength and flexibility. This can include:
  • Range of Motion Exercises: Gentle stretching and movement to improve flexibility.
  • Strengthening Exercises: Gradual introduction of resistance exercises to strengthen the extensor muscles.

Surgical Treatment Approaches

If conservative treatments fail to provide relief or if there is a significant injury such as a complete tendon rupture, surgical intervention may be necessary.

1. Tendon Repair

• In cases of complete tendon rupture, surgical repair may be performed to reattach the tendon to the bone or to repair the tendon itself. This procedure typically involves:
  • Incision: Making an incision over the affected area to access the tendon.
  • Suturing: Using sutures to reattach the tendon ends or to repair any tears.

2. Tendon Transfer

• In some cases, if the extensor tendon is severely damaged, a tendon transfer may be performed. This involves taking a functioning tendon from another part of the hand or wrist and attaching it to the little finger to restore function.

3. Rehabilitation Post-Surgery

• Post-operative rehabilitation is crucial for recovery. This may include:
  • Immobilization: Using a splint or cast to immobilize the finger during the initial healing phase.
  • Gradual Rehabilitation: Following immobilization, a structured rehabilitation program will help restore function and strength.
