Postoperative femoral neuropathy

Area of Science:

• Neurology
• Surgical Complications
• Orthopedic Surgery

Background:

• Postoperative femoral neuropathy is an underrecognized complication.
• It arises from various mechanisms, often following abdominopelvic surgeries.

Purpose of the Study:

• To review the incidence, causes, diagnosis, and management of postoperative femoral neuropathy.
• To emphasize preventative strategies.

Main Methods:

• Literature review of femoral neuropathy following surgical procedures.
• Analysis of causative factors, clinical presentation, and diagnostic signs.
• Discussion of treatment and prognosis.

Main Results:

• Femoral neuropathy commonly follows abdominopelvic operations, frequently linked to self-retaining retractors.
• Nerve compression by retractor blades or ischemia of the intrapelvic nerve are proposed mechanisms.
• A diminished or absent knee jerk is the most reliable diagnostic sign.
• Most cases show mild sensorimotor disturbance with recovery in weeks to months.
• Electromyography (EMG) may be useful for severe or prolonged cases.

Conclusions:

• Postoperative femoral neuropathy is preventable with meticulous surgical technique, particularly in retractor placement.
• Early diagnosis via physical examination and appropriate management lead to favorable outcomes.
• Awareness and careful surgical practice are key to avoiding this complication.
