- Ice Therapy: Applying ice to reduce swelling and pain.
- Pain Management: Using over-the-counter analgesics such as ibuprofen or acetaminophen.
Occupational Therapy
In cases where there is mild sensory loss, occupational therapy may be beneficial. Therapists can provide exercises to improve function and desensitization techniques to enhance sensory recovery.
Surgical Management
Indications for Surgery
Surgical intervention is indicated in cases of:
- Complete nerve transection.
- Severe lacerations.
- Persistent symptoms despite conservative management.
Surgical Techniques
- Nerve Repair: If the nerve is completely severed, direct repair (neurorrhaphy) is performed to reconnect the nerve ends. This is typically done within a few days of the injury to optimize recovery.
- Nerve Grafting: In cases where the nerve ends cannot be approximated, a nerve graft may be necessary. This involves using a segment of another nerve (often from the patient’s own body) to bridge the gap.
- Decompression: If the injury is due to compression (e.g., from a fracture or hematoma), surgical decompression may be performed to relieve pressure on the nerve.
Postoperative Care and Rehabilitation
Follow-Up
Post-surgery, patients require regular follow-up to monitor healing and nerve function. This may include:
- Wound Care: Ensuring the surgical site is clean and free from infection.
