[Lumbar disc herniation]

Area of Science:

• Neurosurgery
• Orthopedics
• Spinal Surgery

Background:

• Lumbar disc herniation (LDH) affects 1-2.5% of adults in industrialized nations, peaking between ages 30-50.
• Clinical symptoms and 'red flags' guide diagnosis and treatment decisions, not solely imaging.
• Most LDH cases resolve with conservative management, though some require surgical intervention.

Purpose of the Study:

• To review the diagnosis and management of lumbar disc herniation.
• To highlight the importance of clinical presentation in surgical decision-making.
• To compare outcomes of minimally invasive versus conventional surgical techniques for LDH.

Main Methods:

• Review of clinical history and physical examination findings.
• Identification of 'red flags' prompting further investigation.
• Analysis of surgical indications based on neurological deficits and time-sensitive emergencies.
• Comparison of minimally invasive endoscopic discectomy with traditional surgical approaches.

Main Results:

• Conservative treatment is effective for most LDH cases.
• Early surgical intervention (within 48-72 hours) is critical for severe motor deficits (MRC < 2).
• Acute conus/cauda symptoms constitute a surgical emergency requiring prompt decompression (within 48 hours) for optimal outcomes.
• Minimally invasive endoscopic discectomy demonstrates equivalent efficacy to conventional surgery regarding pain, function, safety, and recurrence.

Conclusions:

• Clinical assessment is paramount in managing LDH, guiding surgical necessity.
• Timely surgical decompression is essential for patients with severe neurological deficits to prevent long-term disability.
• Minimally invasive endoscopic discectomy offers a viable, effective alternative to traditional open surgery for LDH treatment.
