Nerve Repair; with Nerve Allograft, Each Additional Strand

Name of the Procedure:

• Common Name: Nerve Repair with Allograft
• Medical Term: Nerve Allograft Repair

Summary

Nerve repair with an allograft involves using donor nerve tissue to bridge gaps in damaged nerves, enabling natural regrowth and repair. This procedure is often used when the nerve damage is too extensive for direct nerve suturing.

Purpose

• Medical Condition/Problem: Addresses nerve damage or severance due to trauma or surgery.
• Goals/Outcomes: Restore nerve function, improve sensation, and muscle strength by facilitating nerve regeneration.

Indications

• Symptoms/Conditions: Severe nerve injury, loss of sensation or motor function, complex nerve defects.
• Patient Criteria: Suitable for patients with nerve gaps too large for direct repair, typically over 2-3 centimeters.

Preparation

• Pre-procedure Instructions: Patients may need to fast for 8 hours and adjust medications as directed by their physician.
• Diagnostic Tests: Electromyography (EMG) and nerve conduction studies to assess the extent of nerve damage.

Procedure Description

1. Anesthesia: General or regional anesthesia is administered.
2. Incision: A surgical incision is made to access the damaged nerve.
3. Debridement: Damaged nerve ends are cleaned and trimmed.
4. Allograft Placement: Donor nerve allograft is placed and sutured to bridge the gap.
5. Closure: The surgical site is closed with sutures or staples.

• Tools/Technology: Microsurgical instruments, operating microscope.
• Sedation Details: General anesthesia is common, but local anesthesia may be used in some cases.

Duration

• The procedure typically takes 2 to 4 hours, depending on the complexity and location of the nerve repair.

Setting

• The procedure is usually performed in a hospital or specialized surgical center.

Personnel

• Surgeon with expertise in nerve repair
• Surgical nurses
• Anesthesiologist

Risks and Complications

• Common Risks: Infection, bleeding, scarring.
• Rare Risks: Nerve graft rejection, chronic pain, incomplete nerve regeneration, allergic reaction to anesthesia.
• Management: Close monitoring, antibiotics for infection, pain management strategies.

Benefits

• Expected Benefits: Improved nerve function, restored sensation, and motor function.
• Timeline: Benefits may be seen gradually as nerve regrowth occurs over several months.

Recovery

• Post-Procedure Care: Wound care, avoid strenuous activities, physical therapy.
• Expected Recovery Time: Full recovery can take up to 12 months; nerve function improvement may start within a few weeks.
• Follow-Up Appointments: Regular monitoring and assessments with the surgeon.

Alternatives

• Treatment Options: Direct nerve repair (neurorrhaphy), autografts (using patient’s own nerve tissue), synthetic nerve conduits.
• Pros and Cons: Autografts are more readily accepted by the body but require additional surgery; synthetic conduits are less bio-compatible.

Patient Experience

• During Procedure: Patients are under anesthesia and will not feel the procedure.
• After Procedure: Some pain and swelling at the incision site, manageable with prescribed pain medication.
• Pain Management: Pain relief through medications, ice packs, and rest.
