Full Endoscopic Interlaminar Approach for Paracentral L5-S1 Disc Herniation
0 Views •
2023
Here, we present a protocol to describe the full endoscopic interlaminar approach (FEILA) technique, including every cutoff step required to reach technical proficiency. FEILA is a surgery with a relatively steep learning adaptation. Despite this, any surgeon capable of microdiscectomy can perform FEILA with enough practice and suitable patient selection.

A novel methodology that is employed for the treatment of recurrent glioblastomas is described. This treatment approach employs the application of alternating electric tumor treating fields (TTFields), known as TTF Therapy in combination with bevacizumab, a targeted agent that is currently FDA approved as monotherapy.
FAQs
The annulus is the tissue surrounding the lumbar disc. After earlier treatment or symptom improvement, weakened annular tissue may permit disc material to protrude again. At L5-S1, that renewed protrusion can affect nearby neural structures and produce a return of pain, numbness, or weakness. This mechanism explains why symptom improvement does not always indicate permanent resolution.
A recurrent protrusion at the L5-S1 junction may irritate or compress the S1 nerve root. Because that nerve root is associated with symptoms beyond the spine, patients may experience leg pain, numbness, or weakness in addition to low-back pain. The combination and distribution of symptoms help clinicians assess whether recurrent disc-related nerve involvement is likely.
Symptoms after earlier treatment do not by themselves establish that disc material has returned. Clinical examination evaluates the patient’s symptoms and neurologic findings, while magnetic resonance imaging helps identify structural causes. Together, these assessments can distinguish recurrent herniation from postoperative scar tissue and other explanations for renewed symptoms, supporting a more appropriate management decision.
Renewed low-back pain, leg pain, numbness, or weakness may indicate clinically significant recurrence, particularly when symptoms are consistent with irritation or compression of the S1 nerve root. Their presence does not independently confirm the cause, because other postoperative conditions can produce symptoms. Examination and magnetic resonance imaging are therefore important for clarifying the underlying problem.
Evaluation begins with clinical examination and review of the patient’s renewed or persistent symptoms after prior treatment or improvement. Magnetic resonance imaging then helps assess whether recurrent disc material, postoperative scar tissue, or another cause better explains the presentation. The combined findings guide decisions about observation, rehabilitation, medication, injections, or possible repeat surgery.
Management depends on the clinical findings, imaging results, symptoms, and overall course. When immediate repeat surgery is not selected, observation, rehabilitation, medication, or injections may be considered as part of ongoing care. These options allow clinicians to address symptoms and monitor the patient while using examination and imaging findings to inform later decisions.
Recurrence makes follow-up important because symptoms may reflect renewed disc-related nerve irritation, scar tissue, or another postoperative cause. Clinical examination and magnetic resonance imaging help refine the prognosis and determine whether conservative care, injections, or repeat surgery is appropriate. Long-term management therefore combines symptom monitoring with reassessment rather than relying on symptoms alone.
