Lumbar Herniated Disc Treatment
Lumbar Herniated Disc Treatment Nedir?
A lumbar herniated disc occurs when the fibrous outer ring of an intervertebral disc tears, allowing the inner gel-like nucleus to protrude and compress adjacent nerve roots or the spinal canal. It most commonly affects the L4–L5 and L5–S1 disc levels. Because the nerves at these levels travel through the hip, thigh, knee, and sole of the foot, compression produces radiating pain and numbness along these paths — a syndrome known as sciatica. When muscle weakness accompanies these symptoms, it indicates a more serious neurological compromise that requires prompt evaluation.
Approximately 10% of the working-age population in Türkiye experiences clinically significant lumbar disc pain at some point in their lives. Prolonged sitting, incorrect lifting mechanics, obesity, smoking, and genetic predisposition are important risk factors. With the growing shift toward desk-based and remote work, the incidence of lumbar disc disease is rising noticeably among younger and middle-aged adults. MRI is the primary imaging modality that confirms the diagnosis and guides surgical planning.
Prof. Dr. Ermiş performs lumbar disc surgery under an operating microscope through a minimal 1.5 cm incision (microdiscectomy), allowing patients to stand and walk the same day and to be discharged — in most cases — the following morning. For recurrent or special-indication cases, fully endoscopic discectomy, which reduces muscle trauma even further, is also available. In both approaches, protecting the nerve tissue, achieving rapid pain relief, and returning the patient to professional and social life as quickly as possible are the primary goals.
It is important to emphasize that not every lumbar disc herniation requires surgery. The right treatment strategy depends on herniation size, the severity of nerve compression, the intensity of leg pain, the presence of motor weakness, and the response to prior physical therapy or injection-based treatment. For that reason, successful decision-making relies not only on MRI findings, but also on detailed neurological examination and the degree of functional limitation in everyday life.
Evaluating lumbar disc disease requires more than reading the MRI report. The position of the herniation, whether there is migration of a free fragment, coexistence of canal stenosis, the balance between leg pain and back pain, and the presence of reflex, sensory, or motor deficits all shape the treatment decision. This detailed analysis helps determine which patients can continue with conservative care and which patients should be directed to surgery without delay.
Successful lumbar disc treatment is not limited to removing the offending fragment. A structured walking program, sitting ergonomics, smoking cessation, weight management, and core-strengthening exercises are all essential parts of long-term recovery. Especially in desk workers, professional drivers, and patients who lift heavily, failure to address lifestyle factors may contribute to recurrence or adjacent-level complaints over time.

- Sciatic pain radiating from the lower back to the hip, thigh, knee, and sole of the foot
- Loss of sensation, numbness, and tingling in the foot or toes
- Inability to dorsiflex the ankle (foot drop — requires urgent surgery)
- Significant difficulty sitting for extended periods or driving
- Pain aggravated by coughing, straining, or prolonged walking
- Pain attacks that wake the patient during the night
- Sudden difficulty controlling bladder or bowel function (cauda equina syndrome — emergency)
Tedavi Yöntemleri
Microdiscectomy
Microdiscectomy is the most widely performed and globally recognized gold-standard surgical technique for lumbar herniated disc treatment. The procedure is completed under general anesthesia in approximately 45 to 60 minutes. Pre-operative MRI images are reviewed to precisely localize the herniated fragment. A single 1.5 cm skin incision is made over the affected level; the muscles are gently retracted to each side without being cut, and the operating microscope is brought into the field. Under the high magnification and illumination of the microscope, only the fragment compressing the nerve root is carefully excised while healthy disc tissue, ligaments, and surrounding muscles are maximally preserved. This preservation accelerates postoperative recovery and reduces the risk of adjacent segment involvement over time. Patients typically walk within 4 to 6 hours of surgery, experience rapid resolution of sciatica in most cases, and are discharged the following morning. Return to light activities is usually possible within 1 to 2 weeks.
Endoscopic Discectomy
Fully endoscopic discectomy is a next-generation minimally invasive technique performed through an incision of only 7 to 8 mm — even smaller than conventional microsurgery — under direct live camera visualization. Both transforaminal and interlaminar approaches are available; the choice depends on the herniation level and local anatomy. Because the paraspinal muscles do not need to be dissected, postoperative muscle pain and stiffness are minimized and blood loss is negligible. This technique is especially advantageous for patients with high body mass index, those who have had previous lumbar surgery with resulting epidural scar tissue, and cases involving multi-level pathology. Because the learning curve is steep, outcomes depend heavily on the surgeon's experience; in successful cases, patients may be discharged the same day.
When is surgery necessary?
Surgical indications in lumbar disc disease fall into several clinical categories. First, progressive or acute neurological deficits such as foot drop, bladder or bowel dysfunction, or cauda equina syndrome require immediate surgery without delay. Second, when symptoms including pain, numbness, and motor weakness have persisted beyond 6 weeks, have not responded to conservative measures (analgesics, neuropathic agents, physical therapy, epidural injection), and MRI findings are consistent with the clinical picture, surgery becomes the primary option. Third, when pain severely disrupts daily life, work, and sleep quality and the patient can no longer tolerate conservative treatment, surgical evaluation may be pursued regardless of symptom duration. In cases where symptoms have been present for fewer than 6 weeks and there are no neurological deficits, conservative management is trialed first.
Sıkça Sorulan Sorular
Can a lumbar herniated disc heal without surgery?
Approximately 70 to 80% of mild to moderate cases improve meaningfully with 6 to 12 weeks of conservative treatment — rest, analgesics, physical therapy, and neuropathic agents — because the herniated disc material gradually loses water content, shrinks, and reduces pressure on the nerve root. However, conservative treatment is entirely insufficient in cauda equina syndrome or progressive motor weakness, where emergency surgery is mandatory. Prolonged symptoms lasting over a year should also prompt surgical evaluation to prevent permanent nerve damage.
When can patients return to work after lumbar disc surgery?
Patients with desk-based or seated occupations can generally return to work within 1 to 2 weeks. Those with moderately physically demanding jobs typically require 4 to 6 weeks. Heavy lifting, prolonged standing, and strenuous physical activities should be avoided for at least 6 to 8 weeks, and in some cases up to 3 months. Regular walking and gentle core stabilization exercises from an early stage both accelerate healing and reduce the risk of recurrence.
Can the disc herniate again after surgery?
A recurrent or residual herniation at the same disc level occurs in approximately 5 to 8 out of every 100 patients; this risk is highest in the first 3 months after surgery. Weight management, an active lifestyle, core muscle strengthening, correct sitting posture, and using the legs rather than the lower back when lifting all significantly reduce the risk of recurrence. Quitting smoking also has a positive impact on long-term outcomes by improving disc nutrition.
When does the pain go away after surgery?
After successful microdiscectomy or endoscopic discectomy, the majority of patients experience significant relief of sciatic pain within the first few days to 2 weeks. The speed of recovery is directly influenced by how long the nerve root was compressed before surgery and the degree of nerve damage sustained. Numbness and sensory changes typically resolve more slowly than pain; complete nerve recovery may take 3 to 6 months and in some cases up to 12 months.
