Most cases of extensor tendon injuries can be managed conservatively, especially if the injury is not severe. The following approaches are commonly employed:

• Rest and Activity Modification: Patients are advised to avoid activities that exacerbate pain or strain the injured area. This may involve temporary immobilization of the finger or hand.

• 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, may be recommended to manage pain and inflammation.

• Physical Therapy: Once the acute phase has passed, physical therapy may be initiated to restore range of motion and strength. This often includes gentle stretching and strengthening exercises tailored to the patient's needs.

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 completely torn, a surgical repair may be performed to reattach the tendon to the bone or to the remaining tendon structure. This is typically done under local or general anesthesia.

• Tendon Grafting: In cases where the tendon is severely damaged or retracted, a graft may be used to replace the damaged section. This involves using a tendon from another part of the body or a donor tendon.

• Rehabilitation Post-Surgery: Following surgery, a structured rehabilitation program is crucial. This may involve splinting the finger to protect the repair, followed by gradual mobilization and strengthening exercises.

3. Follow-Up Care

Regular follow-up appointments are essential to monitor healing and adjust treatment as necessary. This may include:

• Assessment of Range of Motion: Evaluating the progress of finger extension and overall hand function.

• Adjusting Therapy: Modifying physical therapy based on the patient's recovery and any complications that may arise.
