INTRODUCTION AND DEFINITION OF THE CONDITION/TREATMENT
The discs between the lumbar vertebrae help absorb load and allow the spine to move. A lumbar disc herniation occurs when disc material protrudes through a weakened or torn part of its outer ring. If the displaced tissue irritates or compresses a nerve root, it can cause leg pain, tingling, numbness or weakness, sometimes alongside low-back pain.
The Turkish expression “closed lumbar disc surgery” is a broad, nontechnical way of describing operations performed through small incisions. One such option is full-endoscopic lumbar discectomy, in which a camera and specialized instruments are used to reach and remove disc material pressing on a nerve. Endoscopic discectomy and microscope-assisted microdiscectomy are different techniques. Neither is automatically the best choice for every person, and most disc herniations do not require surgery.
CAUSES AND SYMPTOMS
Lumbar discs may become less hydrated and resilient over time. Repeated loading, some physical strains and individual susceptibility may contribute to herniation. The location of the herniation and its effect on the nerve matter more than the mere presence of an abnormality on an MRI scan. A visible herniation alone is not an indication for surgery.
Typical symptoms include shooting or burning pain from the lower back or buttock down a particular part of one leg, commonly described as sciatica. Tingling, reduced sensation, difficulty lifting the foot or toes and pain with certain movements may also occur. Other conditions can cause similar symptoms, so an examination is important.
URGENT WARNING: New inability to pass urine, loss of bladder or bowel control, numbness around the genitals or saddle area, or rapidly worsening leg weakness can signal serious nerve compression. Seek emergency medical assessment immediately rather than waiting for a routine appointment.
DIAGNOSTIC METHODS
Assessment starts with a discussion of when the symptoms began, how the pain travels, what makes it worse and how it affects everyday activities. A neurological examination checks leg strength, reflexes, sensation and signs of nerve-root irritation. Magnetic resonance imaging (MRI) may be used to identify the position of a herniation and its relationship to the affected nerve root.
An MRI is not routinely necessary for every episode of back pain; specialist imaging is most useful when the result is likely to alter management. Computed tomography (CT) or electromyography (EMG) may be appropriate in selected situations. Surgery should not be decided on an imaging report alone: the scan, symptoms and examination need to tell a consistent story.
TREATMENT OPTIONS
Many people improve without an operation. Depending on the presentation, initial care may include staying safely active, avoiding prolonged bed rest, clinician-guided pain management and an individualized exercise or physiotherapy programme. An epidural injection may be considered for some people with acute, severe sciatica, after discussing potential benefits and limitations.
Surgery may be discussed when significant leg pain continues to impair daily life despite appropriate nonsurgical treatment, when nerve compression corresponds to the examination and imaging, or when neurological weakness is worsening. The main surgical goal is usually to free the compressed nerve. People with isolated low-back pain do not necessarily obtain the same benefit from disc removal as those with well-matched nerve-root symptoms. Timing and choice of treatment must be individualized.
SURGICAL PROCESS WHEN AN OPERATION IS NEEDED
During endoscopic lumbar discectomy, the surgeon may create a small entry point from the back or side of the lumbar region, depending on the disc level and location. The camera provides a view of the relevant structures while specialized instruments are used to remove the portion of disc pressing on the nerve. An interlaminar or transforaminal route may be selected according to the anatomy. The form of anaesthesia is determined for each patient and procedure.
A smaller incision and earlier mobilization may be possible advantages in selected cases, but they are not guaranteed outcomes. Large or migrated fragments, associated spinal narrowing or instability may make another surgical approach more appropriate. Informed consent should cover infection, bleeding, nerve injury, a tear of the protective nerve covering with cerebrospinal-fluid leakage, anaesthetic complications, recurrent herniation and symptoms that may not fully resolve. The planned approach may occasionally need to change during surgery.
RECOVERY AND THE POSTOPERATIVE PERIOD
Length of hospital stay, walking after surgery and return to work vary with the operation, neurological findings and the physical demands of work. Carefully guided walking may begin early in suitable cases. Instructions on wound care, medicines, lifting, bending, exercise, rehabilitation if indicated and follow-up visits should come from the treating surgical team rather than a fixed timetable applied to everyone.
Radiating leg pain may improve relatively early, while numbness or weakness can take longer to recover. Full recovery is not assured when a nerve has been affected for a long time. New or increasing weakness, changes in bladder or bowel function, fever, significant wound drainage or unexpectedly severe pain warrant prompt medical review; serious neurological symptoms require emergency care. The best approach is determined by the condition and patient, not simply by incision size.
