Objective
This study evaluates surgical strategies based on preoperative computed tomography (CT) findings during unilateral biportal endoscopic (UBE) surgery for thoracic ossification of the ligamentum flavum (OLF) with dural ossification.
Methods
This retrospective study included patients undergoing posterior thoracic laminectomy via UBE surgery to treat symptomatic thoracic stenosis due to OLF. Clinical outcomes were assessed using visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) scores, alongside analyses of preoperative CT and intraoperative videos for dural ossification characteristics.
Results
A total of 34 patients participated, showing significant improvements in VAS and JOA scores postoperatively. All focal dural ossifications exhibiting the tram-track sign were effectively excised without significant dural defects. The circumferential floating technique was employed for cases with the bridge sign, whereas wide excision was warranted for those with the comma sign.
Conclusion
UBE surgery effectively manages progressive thoracic OLF associated with dural ossification. Preoperative CT imaging is essential for assessing dural involvement and guiding surgical techniques. Microscopic surgery is recommended for inexperienced surgeons requiring wide dural excision.

Objective
Endoscopic spine surgery implies possibly severe complications of the central nervous system, from headache to seizures and autonomic dysreflexia. These adverse events might be due to increased intracranial pressure (ICP), presumably induced by increased spinal intra-/epidural pressure caused by fluid irrigation. This study was designed to perform interlaminar endoscopic lumbar discectomy (IELD) at different irrigation fluid settings while monitoring its effect on intra-/epidural and ICPs, with and without dural tears.
Methods
Spinal intradural pressures were measured by introducing catheters through a sacral approach to human cadavers’ lumbar, thoracic, and cervical levels. Additionally, an epidural probe was placed at L3–4. ICP was measured by an intraventricular probe. IELD was performed at L3–4, and the effect of varying irrigation pressures by different endoscopic pump systems and gravity-based irrigation on intra-/epidural and ICP pressures was measured before and after durotomy at L3–4.
Results
Intradural pressure at L3–4 correlated linearly with increasing irrigation pressure, irrespective of the used pump system (median pressure increase at 100-mmHg irrigation pressure: system I: 7 mmHg, r=0.94, p=0.002; system II: 7 mmHg, r=0.89, p=0.017) or gravity (8 mmHg, r=0.93, p=0.242). This effect was also seen intradurally at the thoracic/cervical spine, epidural, and intracranial level, and was even more pronounced with the maneuver of outflow-occlusion and a dural tear present.
Conclusion
While performing IELD, pump pressures correlated linearly to intra-/epidural pressures and ICPs. Pressures did not rise to concerningly high levels without outflow-occlusion, even with increased pump pressures. In the presence of a dural tear, higher pump pressures exacerbated by occlusion may lead to deleterious intradural and ICP elevations.

Objective
This study aimed to evaluate the clinical and radiological outcomes of unilateral laminotomy for bilateral decompression (ULBD) using biportal endoscopic spinal surgery (BESS) in patients with central canal stenosis, with and without low-grade degenerative lumbar spondylolisthesis (DLS).
Methods
A retrospective observational study was conducted on 170 patients who underwent BESS-ULBD between 2015 and 2018, with at least 2 years of follow-up. Patients were categorized into 2 groups: group A (68 patients) with central stenosis and low-grade DLS and group B (102 patients) with central stenosis alone. Clinical outcomes were assessed using the visual analogue scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and Modified MacNab criteria. Radiological assessments included sagittal translation measurements on dynamic flexion-extension radiographs.
Results
Both groups significantly improved clinical outcomes at the final follow-up (p<0.05). Group A’s mean VAS scores improved from 3.8±2.4 to 1.9±2.0 for back pain and from 6.4±1.8 to 2.3±2.0 for leg pain. In group B, back pain improved from 3.9±2.5 to 1.7±1.9, and leg pain from 6.6±2.0 to 2.2±2.2. ODI scores also improved significantly in both groups. Radiological evaluation showed no significant changes in sagittal translation postoperatively, indicating preserved spinal stability. Both groups had comparable clinical outcomes, with no major complications reported.
Conclusion
BESS-ULBD is a safe and effective minimally invasive option for managing central canal stenosis, with or without low-grade DLS. This technique provides substantial symptom relief, preserves spinal stability, and presents a promising alternative to more invasive fusion procedures in carefully selected patients.

Objective
The upper lumbar region has distinctive anatomical characteristics that contribute to the challenges of performing discectomy. We introduce far-lateral transforaminal unilateral biportal endoscopic (UBE) lumbar discectomy for central or paracentral disc herniations in the upper lumbar region.
Methods
We conducted retrospective review of the patients who underwent a far-lateral transforaminal UBE lumbar discectomy at our institution from January 2018 to September 2024. The electronic medical records, operative records, and radiologic images of the patients were reviewed.
Results
A total of 27 patients underwent far-lateral transforaminal UBE lumbar discectomy for central or paracentral disc herniations in the upper lumbar region. The patient had a mean age of 54.0 ± 13.7 years. Operation was performed at the L1–2 level in 3 patients (11.1%), L2–3 in 9 patients (33.3%), and L3–4 in 15 patients (55.6%). The patients were followed-up for a mean of 27.7 ± 19.3 months. The Oswestry Disability Index was significantly decreased from 36.3 ± 6.8 preoperatively to 3.7 ± 3.3 at last follow-up (p < 0.001). The visual analogue scale (VAS) back was significantly decreased from 7.8 ± 0.9 preoperatively to 3.1 ± 0.6 postoperative day 2 (p < 0.001). The VAS leg was significantly decreased from 8.1 ± 0.8 preoperatively to 2.3 ± 0.7 postoperative day 2 (p < 0.001).
Conclusion
The far-lateral transforaminal UBE lumbar discectomy would be a viable surgical option for upper lumbar disc herniations.

Endoscopic spine surgery (ESS) is growing in popularity worldwide. An expanding body of literature demonstrates rapid functional recovery with reduced morbidity compared to open techniques. Both full endoscopic spine surgery, or uniportal endoscopy, and unilateral biportal endoscopy (UBE) can be employed in conjunction with various navigation and enabling technologies for assistance with localization of anatomic orientation and assessment of the intraoperative target spinal pathology. This review article describes various navigation technologies in ESS, including 2-dimensional (2D) fluoroscopic imaging, 2D fluoroscopic navigation, 3-dimensional C-arm navigation, augmented reality, and spinal robotics. Employment of enabling navigation and emerging technology with the registration of patient-specific anatomy enables clear delineation of anatomic landmarks and facilitation of a successful procedure. Additionally, avoidance of common pitfalls during use of navigation systems in ESS is discussed in this review.

The growth of minimally invasive techniques in spine surgery has accelerated in recent years, leading to development of new techniques and technology such as robotic-assisted spine surgery and full-endoscopic surgery. While robotic spine surgery offers the potential of increased precision and accuracy in instrumentation, endoscopic techniques are beneficial in reducing collateral tissue damage and allowing patients a faster return to function. We describe a case where we combine a robotic guidance system with a full-endoscopic technique, the trans-superior articular process decompression. We aim to share our experience as well as an overview of the surgical technique.

The main aim of this video article is to demonstrate the combined use of O-arm navigation and unilateral biportal endoscopy (UBE) to manage far-out syndrome (FOS). In FOS there is entrapment and compression of the fifth lumbar nerve beyond the foramen and between L5 transverse process and the sacral ala at the lumbosacral junction. Conventional microscopic decompression using a paraspinal approach had been the gold standard for its management. However, the surgery is technically challenging due to the deep location of the pathology and intricate anatomy of extraforaminal space. There have been some published reports of unsatisfactory outcomes with microscopic decompression for FOS. We decided to integrate navigation with UBE to increase precision for the management of FOS. A 70-year-old female presented to us with chief complaint of left lower limb radiculopathy since 1 year. She also complained of numbness and paresthesias in her left leg and foot. She was unable to walk for more than 10 minutes due to pain. Her magnetic resonance imaging scan revealed compression of left L5 nerve root in the extraforaminal region. UBE decompression via paraspinal approach was performed for her under O-arm navigation. She experienced immediate relief of her symptoms in the postoperative period. O-arm-navigation-guided UBE is an effective and safer alternative to microsurgical decompression for the management of FOS. This video demonstrates the step-by-step implementation of O-arm navigation with endoscopy and its precise execution.

We present a novel technique to approach far lateral lumbar pathologies using a bitubular, biportal endoscopic system and a paramedian approach. Background: Conventional approaches for lumbar far lateral discectomy range from open approaches to newer minimally invasive approaches such as tubular discectomy and single portal endoscopic discectomy. We present a case of a patient suffering with a left L3–4 and left L4–5 extraforaminal disc herniation who was treated successfully with a left sided bitubular, biportal endoscopic 2 level far lateral discectomy. A paramedian ‘bitubular’ biportal endoscopic approach is safe and effective for far lateral lumbar pathologies with excellent visualisation due to good outflow of irrigation fluid.

To demonstrate the preoperative workup, surgical planning and execution of transforaminal endoscopic thoracic discectomy (TETD) for a giant calcified disc herniation. Surgeries for symptomatic thoracic disc herniations are rare and challenging. The main goal is to achieve sufficient decompression with minimal manipulation of the spinal cord. Conventional surgical techniques may have significant approach-related morbidities and often require additional stabilization. The full endoscopic transforaminal technique is the least invasive approach so far. A 73-year-old female patient with progressive gait disturbance and paraparesis received radiological imaging which revealed a giant calcified thoracic disc herniation at the level T11–12. The preoperative workup, planning and execution of TETD is demonstrated in detail. This report represents a typical educational case of a giant calcified thoracic disc herniation, treated by TETD.

This surgical video demonstrates the full-endoscopic repair of an incidental durotomy, offering practical guidance and insights into the technique. Incidental dural tears occur in up to 1% of lumbar endoscopic surgeries, with risk factors including interlaminar approaches, stenosis decompression, and power drill usage. Although many dural tears are managed with sealant or gel foam, no standard exists for when surgical repair is necessary. Complications such as cerebrospinal fluid leakage, radiculopathy, and neurological deficits can arise, prompting the need for effective repair techniques. A 50-year-old man presented with bilateral leg claudication due to lumbar stenosis (L4–S1). Full-endoscopic decompression was performed, during which an incidental 10-mm dural tear occurred at L5–S1. The nerve root was repositioned into the dural sac, and the tear was repaired using a 6-0 prolene suture with a knot pusher under endoscopic guidance. Gelfoam was applied to aid compression, and irrigation pressure was reduced to prevent increased intracranial pressure. The patient was mobilized after 48 hours and experienced significant symptom improvement without neurological deficits. We propose that dural tears should be repaired when possible to prevent complications. Surgeon experience, tear size, and location are critical factors. This case demonstrates a simple, effective endoscopic repair method, though further studies are needed to establish its long-term efficacy.

We present a case of iatrogenic lumbar foraminal stenosis caused by bone-cement leakage during vertebroplasty, successfully managed using transforaminal endoscopic lumbar foraminotomy (TELF). Vertebroplasty is an effective treatment for osteoporotic vertebral compression fractures (VCFs); however, complications such as bone-cement leakage can lead to vascular or neurological issues, including lumbar radiculopathy. TELF is a minimally invasive surgical option for addressing various forms of lumbar foraminal stenosis. An 82-year-old female patient presented to Gachon University Gil Medical Center with severe right inguinal pain radiating to the anterior thigh and knee. Six months prior, she had undergone vertebroplasty at the L3 level for an osteoporotic VCF at another hospital. Following the procedure, she developed radicular leg pain with a diminished knee jerk reflex, which progressively worsened despite extensive conservative treatment. Magnetic resonance imaging and computed tomography revealed right-sided L3–4 foraminal stenosis caused by bone-cement leakage from the prior vertebroplasty. TELF was performed under local anesthesia to decompress the affected area. Bone-cement fragments, along with hypertrophic bone and ligaments, were successfully removed, achieving sufficient decompression of the exiting nerve root. The patient experienced immediate postoperative pain relief. This case represents the first documented instance of endoscopic decompression for iatrogenic foraminal stenosis following vertebroplasty. TELF, performed safely under local anesthesia, demonstrates its effectiveness as a minimally invasive solution for this rare complication.

This video provides a step-by-step guide for performing the hybrid endoscopic thoracic discectomy using navigation and robotic arm for addressing high migrated calcified disc herniation. With the development of techniques, endoscopic spine surgery has emerged as a reliable treatment for thoracic myelopathy. This approach offers high-resolution, off-axis visualization of the surgical field. The field is poised to advance further as endoscopic instruments are refined, becoming less invasive and more precise through the integration of navigation and robot-assisted systems. A 62-year-old woman presented to us with chief complaints of both legs weakness. She had difficulty standing and walking after squatted due to weakness in her legs and her Oswestry Disability Index score was 66. On examination her both side knee extension and ankle dorsiflexion were grade 4 without dysesthesia. The imaging examination confirmed the diagnosis of thoracic myelopathy caused by a highly migrated calcified disc herniation at T5–6 level. The patient underwent an endoscopic thoracic discectomy using robotic arm and navigation for addressing highly migrated calcified disc herniation, resulting in an excellent outcome. The continuous development of navigation and robotic systems in endoscopic thoracic surgery enhanced accuracy in surgical incisions and instrument placement, as well as improved efficiency in locating pathology and achieving precise decompression. Endoscopic thoracic discectomy combines full-endoscopy and unilateral biportal endoscopic (UBE) techniques to leverage the benefits of both approaches, including the cross-viewing of full-endoscopy cannula and the use of larger Kerrison rongeurs under UBE.

Objective
Spinal stenosis is a prevalent condition; however, the optimal surgical treatment for central lumbar stenosis remains controversial. This study compared the clinical outcomes and radiological parameters of 3 surgical methods: unilateral laminectomy bilateral decompression with unilateral biportal endoscopy (ULBD-UBE), conventional subtotal laminectomy (STL), and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
Methods
This retrospective study included 86 patients, divided into ULBD-UBE (n=34), STL (n=24), and MIS-TLIF (n=28) groups. We evaluated demographics and perioperative factors and assessed clinical outcomes using the visual analogue scale (VAS), Oswestry Disability Index (ODI), and neurogenic intermittent claudication (NIC). Radiological parameters assessed included lumbar lordosis, L4S1 Cobb angle (L4S1), T12S1 Cobb angle (T12S1), increased cross-sectional dural area (CSA), dynamic angulation (DA), dynamic slip (DS), and development of postoperative instability.
Results
The ULBD-UBE group showed a significantly shorter hospital stay duration and operation time and reduced blood loss than the other groups (p<0.001). ULBD-UBE group showed a trend towards greater VAS and ODI improvement at 1 month and postoperative NIC symptom relief. Radiologically, MIS-TLIF group exhibited lower postoperative DA and DS (p<0.001), indicating higher postoperative stability. Postoperative instability was lower in the ULBD-UBE group (2.9%) than in the STL group (16.7%) and similar to the MIS-TLIF group (0.0%) (p=0.028). The CSA was highest in the MIS-TLIF group (295.5%) compared to that in the other groups (ULBD-UBE, 216.3%; STL, 245.2%) (p<0.001).
Conclusion
Compared to other procedures, ULBD-UBE is a safe, effective, and viable surgical procedure for treating lumbar central stenosis.

This article aims to introduce a novel full-endoscopic anterior cervical discectomy and fusion (ACDF) procedure to treat cervical myelopathy. Adoption of endoscopic anterior cervical procedures has been lagging due to safety concerns and the necessity of placing an interbody cage. We have developed novel instrumentation and a modified percutaneous anterior cervical approach that allows a safe and reproducible full-endoscopic ACDF. Specially designed retractor blades facilitate percutaneous placement of a zero-profile cervical interbody cage. A 64-year-old male patient presents with chronic neck pain and bilateral paresthesia in his upper extremities, mild ataxia, and positive Hoffmann sign. He has a history of deep vein thrombosis 5 years prior. Preoperative magnetic resonance imaging and computed tomography scans show a degenerated disk, severe central canal stenosis with cord compression and a hyperintense cord signal at C5–6, compatible with cervical myelopathy. An electromyography of upper extrimities shows suspicion of myelopathy at C5–6. Full-endoscopic ACDF was performed at C5–6 to decompress the canal and restore disk height with a zero-profile interbody cage. Postoperatively the patient showed improvement of his symptoms with reduced pain and disability scores and was discharged from the hospital within 24 hours of the surgery. Outcome is satisfactory at 2-year postoperative follow-up. Full-endoscopic ACDF enables excellent visualization of the posterior endplates and cervical canal with constant irrigation, facilitating treatment of cervical myelopathy. No retraction is required during discectomy and decompression, decreasing the risk of postoperative dysphagia, hoarseness and bleeding. A zero-profile interbody cage can be percutaneously placed with special retractor blades.

Objective
Endoscopic spine surgery is an emerging technique of minimally invasive spine surgery. However, headache, seizure, and autonomic dysreflexia are possible irrigation-related complications following full-endoscopic lumbar discectomy (FELD). Pressure elevation through fluid irrigation may contribute to these adverse events. A validated experimental model to investigate parameters for guideline definition is lacking. This study aimed to create an experimental setting for FELD with pressure assessments to prove the concept of repeatable and sensitive measurement of intracranial, intra- and epidural pressures during spine endoscopy.
Methods
To measure intradural pressure, catheters were introduced through a sacral approach and advanced to lumbar, thoracic, and cervical levels in human cadavers. Similarly, lumbar epidural and intracranial probes were placed. The dural sac was filled with Ringer solution to a physiologic pressure of 15 cmH2O. Lumbar endoscopy was performed on 3 human cadavers at the L3–4 level. Pressure changes were measured continuously at all sites and the effects of backflow-occlusion were monitored.
Results
Reproducibility of the experimental model was validated with catheters at the correct locations and stable compartmental pressure baselines at all levels for 3 specimens (mean±standard deviation: 1.3±2.9 mmHg, 9.0±2.0 mmHg, 6.0±1.2 mmHg, respectively). Pressure increase could be detected sensitively by closing the system with backflow-occlusion.
Conclusion
An experimental setup for feasible, repeatable, and precise pressure measurement during FELD in a human cadaveric setup has been developed. This allows investigation of the effects of endoscopic techniques and pump pressures on intra-, epidural and intracranial pressure and enables ranges of safe pump pressures per clinical situations.
