• Application of Ice: Ice packs can be applied to the affected area for 15-20 minutes every few hours to reduce swelling and pain.

3. Compression and Elevation

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

4. Pain Management

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

5. Physical Therapy

• Rehabilitation Exercises: Once the acute pain subsides, a physical therapist may guide the patient through exercises to restore strength and flexibility in the thumb and wrist.

Surgical Treatment Approaches

If conservative treatments fail to provide relief or if the injury is severe, surgical intervention may be necessary. Surgical options can include:

1. Tendon Repair

• Surgical Repair: If the extensor tendon is ruptured or severely damaged, 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. Debridement

• Removal of Damaged Tissue: In some cases, surgery may involve debriding (removing) damaged tissue to promote healing.

Postoperative Care and Rehabilitation

Following any surgical intervention, a structured rehabilitation program is crucial for recovery:

• Immobilization: The thumb may be placed in a splint or cast to immobilize it during the initial healing phase.
• Gradual Rehabilitation: Physical therapy will typically begin with gentle range-of-motion exercises, progressing to strengthening exercises as healing allows.

Conclusion

The treatment of an unspecified injury of the extensor muscle, fascia, and tendon of the left thumb at the wrist and hand level (ICD-10 code S66.202) typically begins with conservative management, including rest, ice, compression, and physical therapy. Surgical options are reserved for more severe cases or when conservative measures fail.
