Repair of Median Nerve Motor Injury Using a Collagen Nerve Conduit: A Case Report

Area of Science:

• * Regenerative medicine
• * Peripheral nerve repair
• * Biomaterials science

Background:

• * Peripheral nerve injuries can lead to significant functional deficits.
• * Median nerve injuries, particularly those involving segmental defects, pose challenges for surgical repair.
• * Synthetic nerve conduits offer a potential alternative to autografts for bridging nerve gaps.

Purpose of the Study:

• * To evaluate the efficacy of a synthetic collagen conduit in repairing a segmental median nerve defect.
• * To assess functional recovery following nerve repair using a collagen conduit.

Main Methods:

• * A 19-year-old male patient with a median nerve injury and a 10-mm segmental defect was treated.
• * Surgical repair was performed using a Renerve® synthetic collagen conduit.
• * Functional outcomes, including sensation and motor function (thumb opposition), were assessed postoperatively.

Main Results:

• * Significant functional recovery was observed at 31 months post-surgery.
• * Restored thumb opposition and improved sensation were noted.
• * Sensory misdirection was present, indicating incomplete sensory recovery.

Conclusions:

• * Synthetic collagen nerve conduits may be effective for treating motor nerve injuries.
• * Favorable conditions for nerve regeneration are crucial for successful outcomes with collagen conduits.
• * Further research is warranted to optimize nerve conduit technology and predict outcomes.
