Objective : The purpose of this study was to evaluate the efficacy of a transforaminal suprapedicular approach, semi-rigid flexible curved probe, and 3-dimensional reconstruction computed tomography (3D-CT) with discogram in the endoscopic treatment of non-contained lumbar disc herniations. Methods : The subjects were 153 patients with difficult, non-contained lumbar disc herniations undergoing endoscopic treatment. The types of herniation were as follows : extraforaminal, 17 patients; foraminal, 21 patients; high grade migration, 59 patients; and high canal compromise, 56 patients. To overcome the difficulties in endoscopic treatment, the anatomic structures were analyzed by 3D reconstruction CT and the high grade disc was extracted using a semi-rigid flexible curved probe and a transforaminal suprapedicular approach. Results : The mean follow-up was 18.3 months. The mean visual analogue scale (VAS) of the patients prior to surgery was 9.48, and the mean postoperative VAS was 1.63. According to Macnab's criteria, 145 patients had excellent and good results, and thus satisfactory results were obtained in 94.77% cases. Conclusion : In a posterolateral endoscopic lumbar discectomy, the difficult, non-contained disc is considered to be the most important factor impeding the success of surgery. By applying a semi-rigid flexible curved probe and using a transforaminal suprapedicular approach, good surgical results can be obtained, even in high grade, non-contained disc herniations.

Foraminal or extraforaminal Far Lateral Disc Herniations (FLDH) extending into or beyond the foraminal zone have been recognized as between 7-12% of all lumbosacral disc herniations. Conventional posterior laminectomy may not provide good access to a herniation that lies far lateral to the lateral margin of the pedicle. Use of the endoscopic technique through a percutaneous approach to treat such FLDH patients can decrease the surgical morbidity while achieving better outcomes. We made an effort to utilize the advantages of percutaneous endoscopic lumbar discectomy (PELD) and to determine the appropriate approach for FLDH at the level between the 5th Lumbar and first Sacral vertebrae(L5-S1). The authors present a case of an endoscopically resected lumbar extruded disc of the left extraforaminal zone with superior foraminal migration at the level of L5-S1, which had led to foot drop, while placing the endoscope in the anterior epidural space without facetectomy.

Lumbar microdiscectomy (MD) is the gold standard for treatment of lumbar disc herniation. Generally, the surgeon attempts to protect the facet joint in hopes of avoiding postoperative pain/instability and secondary degenerative arthropathy. We believe that preserving the facet joint is especially important in young patients, owing to their life expectancy and activity. However, preserving the facet joint is not easy during lumbar MD. We propose several technical tips (superolateral extension of conventional laminotomy, oblique drilling for laminotomy, and additional foraminotomy) for facet joint preservation during lumbar MD.

The objective of this study is to report an accidental detection of colorectal cancer (CRC) metastasis to spine during conservative treatment for lumbar disc herniation. We treated a 65-year-old female who was diagnosed with lumbar disc herniation on September 2019 by acupuncture, pharmacopuncture, cupping treatment, chuna manual therapy, herbal medicine treatment, medicine treatment and physical therapy. After that we analyzed medical record from December 12, 2019 to February 11, 2020. The patient was diagnosed with CRC and received tumor resection in 2014. After 2 times of chemotherapy, she arbitrarily interrupted the treatment. Since she stated that CRC treatment was terminated, we had difficulty in finding connection between symptom and CRC. During the treatment period, compression fracture at L3 body was found, which was caused by CRC metastasis. Rigorous question, appropriate radiological and clinical tests are required to patients who have history of malignant tumor.

Objective: The purpose of this study is to evaluate the disc block subluxation for lumbar scoliosis and herniation of nucleus pulpous (HNP). Methods: We used AP & Lateral view X-ray for patients. And we measured of disc wedge angle, vertebral body rotation to evaluate the typical and atypical disc block subluxation. Results: On the analysis of the lateral view X-ray, 4th lumbar intervertebral disc angle (I.V.D angle) showed $4^{\circ}$, $5^{\circ}$, $3^{\circ}$, $0^{\circ}$ in the cases. On the 4th lumbar analysis of the AP view X-ray, lumbar scoliosis showed right disc wedge angle was $11^{\circ}$ (case 1), $17^{\circ}$ (case 2) and left vertebral body rotation was 13mm, 6mm. Lumbar HNP showed left disc wedge angle was $5^{\circ}$ (case 3), $4^{\circ}$ (case 4) and left vertebral body rotation was 2mm, 4mm. Conclusions: Disc block subluxation has been in lumbar scoliosis, but not been in lumbar HNP.

Intradural lumbar disc herniation (ILDH) is rare. In this report, authors present 2 cases of ILDHs associated with severe adhesion between the dural sac and posterior longitudinal ligament. In a 40-year-old man, ILDH occurred in association with epidural adhesion due to ossification of the posterior longitudinal ligament (OPLL). In other 31-year-old man, ILDH occurred in presence of epidural adhesion due to previous spine surgery.

Objective : To prospectively assess the diagnostic and clinical value of a new technique (3-tesla magnetic resonance myelography, 3T MRM) as compared to computed tomographic discography (disco-CT) in patients with far lateral disc herniation. Methods : We evaluated 3T MRM and disco-CT of 25 patients, whom we suspected of suffering from far lateral disc herniation. Using an assessment scale, 4 observers examined independently both 3T MRM and disco-CT images. We analyzed observer agreement and the accentuation of each image. Results : We found complete matching, and observer agreement, between high resolution images of 3T MRM and disco-CT for diagnosing far lateral disc herniation. Conclusion : We think noninvasive 3T MRM is an appropriate diagnostic tool for far lateral disc herniation as compared to disco-CT.

Objectives We have attempted to provide the basis of treatment effects by considering foreign & domestic randomized controlled trials (RCTs), being implemented with catgut-embedding therapy for lumbar disc herniation. Methods We found the literatures prepared in Korean, English, and Chinese by December 2014 in electronic databases (Pubmed, Science Direct, Proquest, OASIS, KMbase, NDSL, RISS, National Assembly Library). We choosed RCTs by selection criteria through abstracts & articles, extracted and analyzed data. Cochrane's Risk of Bias Tool was used & implemented for the risk of bias. Results The total of 17 studies were included in the review. 88.2% of studies were accomplished within the last decade. The experimental group has shown more significant effects in 70.6% of studies, and the long-term & partial significant results were obtained in 29.4% of studies. Affected lumbar area and pelvic limb area with radiating pain were mostly selected for acupoint. Conclusions Overall and partial significant results were obtained from 17 foreign & domestic comparative RCTs which substantiates the treatment effects of catgut-embedding therapy for lumbar disc herniation. Since all studies, however, were exposed to the risk of bias, so future research of higher quality shall be necessary.

Objectives The purpose of this study is to find out the relationship between the hip internal rotation angle and the site of herniation of single level lumbar intervertebral disc. Methods This study was carried out to 418 patients with lumbar disc herniation diagnosed by M.R.I, who visited Bu-Chun Jaseng Hospital of Korean Medicine with low back pain. Researchers measured their hip internal rotation angle and analyzed the relationship between the hip internal rotation angle and the site of herniation of single level lumbar intervertebral disc. Results 1. Excessive right internal rotation of hip joint increases risk of L5/S1 HIVD. 2. Limited left internal rotation of hip joint decreases risk of L4/L5 HIVD. 3. In cases of L4/L5 HIVD level, there was evidence that the prevalence of HNP in men was 1.85 times as higher than that in women. 4. In cases of L5/S1 HIVD level, there was the evidence that the prevalence of HNP in men was 0.64 times as lower than that in women. Conclusions In single-segment lumbar HIVD patients, limited left internal rotation of hip joint decreases risk of HIVD of L4/5 and excessive right internal rotation of hip joint mainly leads to L5/S1 HIVD.
