• Ice Therapy: Applying ice packs to the affected area can help reduce swelling and alleviate pain. This is typically recommended for 15-20 minutes every few hours during the initial days post-injury.

• Compression and Elevation: Using a compression bandage can help minimize swelling. Elevating the hand above heart level can also assist in reducing edema.

• Pain Management: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, can be used to manage pain and inflammation.

• Physical Therapy: Once the acute phase has passed, physical therapy may be recommended to restore range of motion, strength, and function. This can include stretching and strengthening exercises tailored to the injury.

2. Surgical Intervention

In cases where conservative treatment fails or if there is a complete rupture of the extensor tendon, surgical intervention may be necessary. Surgical options include:

• Tendon Repair: If the extensor tendon is torn, surgical repair may involve suturing the tendon ends together. This is typically performed under local or general anesthesia.

• Tendon Grafting: In cases where the tendon is severely damaged or retracted, a graft from another tendon may be used to restore function.

• Reconstruction: For complex injuries involving multiple structures, a more extensive surgical reconstruction may be required to restore the anatomy and function of the finger.

3. Postoperative Care and Rehabilitation

Following surgery, a structured rehabilitation program is crucial for optimal recovery. This may include:

• Immobilization: The finger may be placed in a splint or cast to protect the repair during the initial healing phase.

• Gradual Mobilization: Once healing is underway, a gradual increase in movement and strength exercises will be introduced to prevent stiffness and regain function.

• Follow-Up Care: Regular follow-up appointments are essential to monitor healing and adjust rehabilitation protocols as needed.

Conclusion

The treatment of an unspecified injury of the extensor muscle, fascia, and tendon of the fingers at the forearm level (ICD-10 code S56.40) typically begins with conservative management, focusing on rest, ice, compression, and physical therapy. Surgical options are reserved for more severe cases where conservative measures are insufficient.
