• Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) or other analgesics may be prescribed to manage pain and inflammation.

2. Surgical Intervention

In cases where conservative management fails or if the injury is severe (e.g., complete nerve transection), surgical options may be considered:

• Nerve Repair: If the nerve is severed, surgical repair may be necessary to reconnect the nerve ends.
• Nerve Grafting: In cases where the nerve ends cannot be directly sutured together, a graft from another nerve may be used to bridge the gap.
• Decompression Surgery: If the nerve is compressed (e.g., due to a fracture or swelling), surgery may be performed to relieve the pressure.

3. Postoperative Rehabilitation

Following surgical intervention, a structured rehabilitation program is essential:

• Physical Therapy: Continued therapy focuses on regaining strength, flexibility, and function in the affected arm.
• Occupational Therapy: This may be necessary to help patients adapt to daily activities and regain independence.

4. Monitoring and Follow-Up

Regular follow-up appointments are crucial to monitor recovery progress and adjust treatment plans as necessary. This may include:

• Re-evaluation of Symptoms: Assessing pain levels, sensory function, and motor skills.
• Adjusting Therapy: Modifying rehabilitation exercises based on recovery progress.

Conclusion

The treatment of an unspecified nerve injury at the forearm level (ICD-10 code S54.90) typically begins with conservative management, progressing to surgical options if necessary. A comprehensive approach that includes initial assessment, conservative treatment, potential surgical intervention, and postoperative rehabilitation is essential for optimal recovery.
