• Avoiding Aggravating Activities: Patients are advised to refrain from activities that exacerbate pain or strain the injured finger.
• Splinting: A splint may be used to immobilize the finger and allow for healing, particularly in the acute phase.

2. Ice Therapy

• Cold Packs: Applying ice to the injured area for 15-20 minutes every few hours can help reduce swelling and pain.

3. Compression and Elevation

• Compression Bandages: These can help minimize swelling.
• Elevation: Keeping the hand elevated above heart level can also assist in reducing swelling.

4. Pain Management

• Over-the-Counter Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can be used to manage pain and inflammation.

5. Physical Therapy

• Rehabilitation Exercises: Once the initial pain and swelling decrease, a physical therapist may guide the patient through exercises to restore range of motion, strength, and function.

Surgical Treatment Approaches

If conservative management fails or if the injury is more severe (e.g., complete tendon rupture), surgical intervention may be necessary. Surgical options include:

1. Tendon Repair

• Surgical Repair: If the extensor tendon is completely ruptured, surgical repair may be performed to reattach the tendon to the bone or to repair the tendon itself.

2. Tendon Transfer

• Transfer Procedures: In cases where the tendon is irreparably damaged, a tendon transfer from another muscle may be considered to restore function.

3. Reconstruction

• Reconstructive Surgery: In complex cases, reconstructive techniques may be employed to restore the anatomy and function of the extensor mechanism.

Postoperative Care and Rehabilitation

Following any surgical intervention, a structured rehabilitation program is essential for optimal recovery. This may include:

• Immobilization: The finger may need to be immobilized in a splint for a period post-surgery.
• Gradual Rehabilitation: A gradual increase in activity and specific exercises will be introduced to regain strength and flexibility.
