Résumé :
A modified interlaminar (MIL) approach has been proposed for improved accessibility to the target epidural space. However, even with fluoroscopic guidance, uncertainty about the distance between the needle tip and the epidural space can remain. Using the contralateral oblique (CLO) view, determination of the epidural space can be easier with clearer identification of the interlaminar opening. We inserted the needle at the midpoint of the interlaminar opening on the fluoroscopic anteroposterior (AP) view and made the needle oriented toward the pedicle of the target side. Then, CLO view was created by rotating the intensifier approximately 45 degrees to the contralateral side of the target. Through the CLO view, the ventral interlaminar line (VILL) was confirmed and the needle was able to enter the epidural space more easily. The medical records of 29 patients who were conducted MIL approach using CLO view were retrospectively analyzed to evaluate the effectiveness and safety of this procedure. The accessibility to the ventral epidural space was 93.1%. There was no procedure-related complication. Using CLO view, uncertainty can be reduced during the MIL approach, which in turn shortens procedure time and improves safety.

Résumé :
Several treatment modalities have been proposed for foraminal stenosis, but the treatment options remain unsatisfactory. Previous studies have shown that transforaminal balloon adhesiolysis may be effective in patients with refractory lumbar foraminal stenosis. However, in patients with a high iliac crest, balloon catheter insertion may be difficult via a conventional transforaminal approach (particularly targeting the L5–S1 foramen). It has been reported that an epidural catheter can be placed easily by a contralateral interlaminar retrograde foraminal approach. Therefore, we applied this approach to L5–S1 transforaminal balloon adhesiolysis in patients with a high iliac crest. We retrospectively analyzed data from 22 patients who underwent combined epidural adhesiolysis and balloon decompression (balloon adhesiolysis) using the novel foraminal balloon catheter via a contralateral interlaminar retrograde foraminal approach. The pain intensity significantly decreased over the three-month period after balloon adhesiolysis (p < 0.001). There were no complications associated with the balloon procedure. The present study suggests that balloon adhesiolysis for L5-S1 foramen via a contralateral interlaminar retrograde foraminal approach may be an effective alternative for patients with a high iliac crest and refractory lumbar radicular pain due to lumbar foraminal stenosis. In addition, detailed procedural aspects are described here.

Résumé :
Abstract Lumbar radiculopathy often results from direct compression of the exiting nerve roots. This may be caused mainly by spondylotic changes with any contribution from components like a herniated disc, facet overgrowth, and ligamentum flavum hypertrophy, or any combination of them. There are a wide range of surgical treatments directed at decompressing the neural elements. Over the last decade, endoscopic spine surgery has gained popular interest because of potential benefits, including decreased bony removal, less muscle disruption, and enhanced visualization.1 A unilateral endoscopic surgical approach can accomplish an effective bilateral decompression using the ipsilateral-contralateral technique.2 This method allows for addressing both central and bilateral recess stenoses. We present a case of a 48-yr-old female with persistent bilateral lower extremity radicular pain worse on the left side with severe lumbar 4/5 stenosis and a left-sided synovial cyst causing significant foraminal narrowing. This 2-dimensional video illustrates the technique used for an endoscopic interlaminar approach for lumbar 4/5 ipsilateral and contralateral decompression. We highlight key elements regarding the positioning, workflow, and surgical technique to successfully perform this approach. Patient consented to the procedure.

Résumé :
Background and objectives: The purpose of this study was to compare and to analyze contrast spread patterns between the paramedian and midline approaches to cervical interlaminar epidural injection (CIEI). Materials and Methods: We retrospectively enrolled 84 CIEI cases that had been performed for unilateral cervical spinal pain from April 2019 to April 2020. After 3 mL of contrast had been injected into the epidural space, fluoroscopic images were obtained. The CIEI was divided into a midline (Group M, n = 42) and a paramedian (Group P, n = 42) approach by anteroposterior imaging. The P Group was classified into a more medial (Group Pm, n = 26) and a more lateral (Group Pl, n = 16) group. Using ImageJ on an anteroposterior image, we assessed the grayscale brightness ratio of the ipsilateral or contralateral side of the vertebral body as well as the intervertebral disc space one level just above the needle location. We identified the dispersion of contrast into the ventral epidural space. Results: The grayscale brightness ratio was significantly higher in Group P than in Group M (p < 0.001). The incidence of ventral epidural spread in Group M was 57.1% versus 88.1% in Group P, which was significantly different (p = 0.001). Conclusions: The fluoroscopic CIEI finding in the paramedian approach predominantly showed an excellent delivery of the injectate to the ipsilateral side in comparison to the contralateral side. This showed a greater advantage in delivery toward ventral epidural space as compared to the midline approach.

Résumé :
Background: Multifocal intra-and-extraspinal lumbar stenotic lesions could be decompressed with one endoscopic surgical approach, which has the advantages of functional structure preservation, technical efficacy, and safety. Methods: A retrospective study was performed on 48 patients who underwent uniportal endoscopic contralateral approach due to coexisting lateral recess, foraminal, and extraforaminal stenosis at the L5-S1 level. Foraminal stenosis grade and postoperative dysesthesia (POD) were analyzed. Visual analog scale (VAS) pain scores, modified Oswestry Disability Index (ODI) scores, and MacNab criteria for evaluating pain disability and response were analyzed. Results: The foraminal stenosis grade of the treated spinal levels was grade 1 (n = 16, 33%), grade 2 (n = 20, 42%), and grade 3 (n = 12, 25%). The rate of occurrence of POD grade 2 and above, which may be related to intraoperative dorsal root ganglion (DRG) retraction injury, was revealed to be 4.2% (two with grade 2, none with grade 3). The patients showed favorable clinical outcomes. Conclusions: Uniportal endoscopic interlaminar contralateral approach is an effective procedure to resolve combined stenosis (lateral recess, foraminal, and extraforaminal region) with one surgical approach at the L5-S1 level. It may be a minimal DRG retracting and facet joint preserving procedure in foraminal and extraforaminal decompression.

Résumé :
Background and Study Aims The technique and instrumentation of percutaneous endoscopic lumbar diskectomy (PELD) have significantly improved. Thus its indications have been gradually expanding. Down-migrated disk, in particular, is regarded inaccessible by rigid instrumentation due to poor visualization and limited accessibility. We introduce a combination of transforaminal and interlaminar PELD for extensive down-migrated disk herniation at the L4–L5 level. Patients and Methods In the first case, a 48-year-old man had left L5 radicular pain. Magnetic resonance imaging (MRI) showed that L4–L5 disk herniation extended to the L5 lower end-plate level. In the second case, a 39-year-old man presented with right L5 and S1 radiculopathy. MRI showed right huge extensive down-migrated disk herniation from the L4–L5 disk space to the S1 pedicle level. Back pain and leg pain were measured using the visual analog scale (VAS). In the first case, transforaminal PELD with foraminoplasty removed the disk fragment from the L4–L5 disk space to the mid-L5 pedicle level. Interlaminar PELD removed the remaining disk below the mid-L5 pedicle. In the second case, first, contralateral (left) transforaminal PELD at L4–L5 removed disk fragments located at the subannular and subligamentous area as well as the upper part of the down-migrated disk herniation. Second, interlaminar PELD via an ipsilateral (right) L5–S1 interlaminar space removed the remains of the extensively down-migrated disk herniation. Results In the first case, the VAS scores for back and leg pain were improved from 6 and 8 to 2 and 1, respectively. Postoperative MRI showed complete removal of the disk fragment. In the second case, the VAS scores for back and leg pain improved from 7 and 9 to 3 and 1, respectively, after PELD. Postoperative MRI showed complete removal of a huge disk herniation. Both patients were discharged the day after PELD. Follow-up examinations showed no recurrence. Conclusions It is difficult to remove entire disk fragments using only a transforaminal or interlaminar approach for extensive down-migrated disk herniation. Therefore a combination of transforaminal and interlaminar PELD may be effective for extensive down-migrated disk herniation at L4–L5.

Résumé :
Abstract Objective To describe and analyze lumbar epidural contrast spread patterns in antero-posterior (AP), lateral, and contralateral oblique (CLO) views. Methods Lumbar epidural contrast spread patterns after interlaminar injection were prospectively collected in AP, lateral, and several CLO views and analyzed for multiple variables; three-dimensional mapping was also performed. Results Epidural contrast patterns were prospectively analyzed in 28 subjects. The median volume of contrast injected was 2 mL; the AP view was more sensitive than the lateral view to detect foraminal uptake (13/28, 46%, 95% confidence interval [CI] = 27–66%, vs 7/28, 25%, 95% CI = 11–45% subjects). CLO view demonstrated the most consistent location for epidural contrast spread, with contrast contacting the ventral laminar margin in 28/28 (100%, 95% CI = 87–100%) patients. The most common location of contrast spread in the lateral view was at the facet joint lucency, with only 8/28 (29%, 95% CI = 13%–49%) subjects showing contrast contacting the spinolaminar junction. Lateral view was more sensitive than the CLO view in ventral epidural contrast spread detection. The extent and distribution of the spread did not bear any relationship to the volume injected or to the needle location in AP view. Conclusions CLO view provides the most consistent landmark for lumbar epidural contrast spread, and lateral view is most suited to confirming ventral epidural spread. The AP view may be the most optimal for determining target access when considering access to the dorsal root ganglia; in an individual patient, the volume injected and needle location in AP view do not reliably predict target access. The volume to be injected and the need to re-access or obtain multisite access must be prospectively determined, based upon observation of the spread.

Résumé :
Posterior lumbar interbody fusion (PLIF) is an established technique that allows circumferential fusion of lumbar spine through a single incision. A variation of PLIF called transforaminal lumbar interbody fusion (TLIF) uses a posterior approach to the spine but accesses the disc space via a path that runs through the far lateral portion of the vertebral foramen. TLIF provides the surgeon with a fusion procedure that reduces many of the risks and limitations associated with PLIF. Like PLIF, TLIF is easily enhanced when combined with posterolateral fusion (PLF) and instrumentation. TLIF offers an advantage in that it is usually done via a unilateral approach preserving the facet joint and the interlaminar surface on the contralateral side [1]. It minimizes soft tissue stripping and neural element retraction compared to PLIF, while providing a single-stage circumferential fusion. This study compared the biomechanical performance of these two constructs in flexion, extension, and lateral bending under physiologic compressive preloads.
