Neurolysis

Area of Science:

• Neurosurgery
• Peripheral Nerve Anatomy

Background:

• Classification and terminology for neurolysis are proposed based on peripheral nerve anatomy.
• Detailed explanation of various neurolysis techniques is provided.

Observation:

• Animal studies show fibrosis predominantly in the epineurial layer after saline neurolysis, epineurectomy, or interfascicular neurolysis.
• The extent of scarring produced by neurolysis itself is a critical factor in its consideration.

Findings:

• Neurolysis is advisable only if existing nerve scarring is more severe than the scarring resulting from the procedure.
• The procedure appears beneficial for nerve lesions in continuity that do not recover spontaneously.
• Current literature lacks clear guidelines for neurolysis after nerve trunk discontinuity repair.

Implications:

• Standardized terminology and classification can improve neurolysis reporting and understanding.
• Future advancements in nerve stimulation and intraoperative recording may enhance the utility of interfascicular neurolysis.
