INTRODUCTION AND DEFINITION
Microdiscectomy uses microscopic magnification to remove disc material compressing a lumbar nerve root; it differs from a fully endoscopic approach.
This page provides general patient information rather than an individual diagnosis. Decisions depend on symptoms, examination findings, relevant tests and patient preferences. Two people with the same diagnosis may require different care plans.
CAUSES AND SYMPTOMS
Radiating leg pain, tingling and weakness may occur; an MRI finding alone does not require surgery.
The intensity of symptoms does not always match the extent of changes seen on scans. New significant weakness, walking difficulty or changes in bladder or bowel control require urgent medical assessment.
DIAGNOSIS AND ASSESSMENT
Nerve examination findings should match the level and side of disc compression on MRI.
Assessment begins with the clinical history and an appropriate examination of strength, sensation and reflexes. X-rays, MRI, CT or nerve studies are used when they can answer a specific clinical question. A scan report alone does not establish the need for surgery.
TREATMENT OPTIONS
Many patients improve with activity, exercise and suitable pain care; persistent disabling leg pain or progressive weakness may warrant surgery.
Management depends on the underlying cause, severity, overall health and realistic goals of treatment. Depending on the condition, monitoring, nonoperative care, activity modification, rehabilitation or clinician-selected medication may be considered. No single treatment suits everyone.
SURGICAL PROCESS WHEN INDICATED
Through a limited incision the surgeon protects the nerve root while removing the compressive fragment; infection, dural tear, nerve injury and recurrent herniation are possible.
Before surgery, the team should discuss likely benefits, alternatives and individual risks. Depending on the operation, complications may include bleeding, infection, anesthesia problems, nerve or spinal cord injury, and persistent symptoms; no outcome can be guaranteed.
RECOVERY AND POSTOPERATIVE PERIOD
Leg pain may ease early, whereas numbness and weakness can recover more slowly; lifting and return to work are personalized.
Follow-up, movement restrictions and return to work or sport vary with the procedure and neurological findings. New or worsening weakness, fever, wound drainage or bladder and bowel changes require prompt medical review.
