Background: This study aims to statistically analyze and compare the curative effect and satisfaction level between typical traditional Korean medicine treatment and nonsurgical spinal decompression treatment. Methods: Of the patients who were diagnosed with the cervical or lumbar herniated intervertebral disc at the Department of Acupuncture and Moxibustion Medicine at the Daejeon Korean Medicine Hospital from April 14^th to August 25^th, 2019, this study retrospectively analyzed the medical records of 31 patients who underwent nonsurgical spinal decompression treatment and traditional Korean medicine (assigned to Group A) and another 31 patients who received typical traditional Korean medicine alone (assigned to Group B). The clinical data were analyzed using IBM SPSS Version 23.0. Results: No statistically significant differences appeared in terms of sociodemographic, condition, and therapeutic characteristics, except whether the patient received Western medicine treatment, before or after a treatment with traditional Korean medicine. Group A exhibited higher variations in numeric rating scale, EuroQol- 5 dimension and EuroQol visual analogue scale scores compared to Group B as determined by independent sample t test and analysis of covariance. In addition, the satisfaction score of Group A was higher than that of Group B The result of cross analysis revealed that desire for continued treatment in Group A was higher than that of Group B. Conclusion: This retrospective observational study showed that the patients with nonsurgical spinal decompression treatment reported a greater reduction in pain, improved quality of life and satisfaction than patients receiving typical traditional Korean medicine.

Objectives : Due to recent developments and the wide application of percutaneous transforaminal discectomy (PTED) in China, we herein compare its clinical effects with microendoscopic discectomy (MED) for the treatment of lumbar disc herniation in terms of recurrence and revision rates. Methods : Six databases, namely, PubMed, EMBASE, Cochrane Library, Ovid, China National Knowledge Infrastructure and Wanfang, were searched by computer. The literature was screened according to inclusion and exclusion criteria, and the quality of the included literature was evaluated. After extracting the data from the papers, Review Manager 5.2 software (Cochrane Collaboration, Oxford, UK) was applied to analyze these data. Finally, sensitivity and publication bias analyses of the results were conducted. Results : A total of 12 studies consisting of 2400 patients were included in this meta-analysis. A comparison of PTED with MED revealed higher postoperative recurrence and postoperative revision rates for PTED (odds ratio [OR] recurrence, 1.60; 95% confidence interval [CI], 1.01 to 2.53; p=0.05 and OR revision, 1.77; 95% CI, 1.18 to 2.64, p=0.006). Conclusion : PTED has a number of advantages because it is a minimally invasive surgery, but its recurrence and revision rates are higher than MED. Therefore, MED should not be completely replaced by PTED.

Objective : To characterize perioperative biomechanical changes after thoracic spine surgery. Methods : Fifty-eight patients underwent spinal instrumented fusions and simple laminectomies on the thoracolumbar spine from April 2003 to October 2008. Patients were allocated to three groups; namely, the laminectomy without fusion group (group I, n = 17), the thoracolumbar fusion group (group II, n = 27), and the thoracic spine fusion group (group III, n = 14). Sagittal (ADS) and coronal (ADC) angles for adjacent segments were measured from two disc spaces above lesions at the upper margins, to two disc spaces below lesions at the lower margins. Sagittal (TLS) and coronal (TLC) angles of the thoracolumbar junction were measured from the lower margin of the 11th thoracic vertebra body to the upper margin of the 2nd lumbar vertebra body on plane radiographs. Adjacent segment disc heights and disc signal changes were determined using simple spinal examinations and by magnetic resonance imaging. Clinical outcome indices were determined using a visual analog scale. Results : The three groups demonstrated statistically significant differences in terms of angle changes by ANOVA (p<0.05). All angles in group I showed significantly smaller angles changes than in groups II and III by Turkey's multiple comparison analysis. Coronal Cobb's angles of the thoracolumbar spine (TLC) were not significantly different in the three groups. Conclusion : Postoperative sagittal balance is expected to change in the adjacent and thoracolumbar areas after thoracic spine fusion. However, its prevalence seems to be higher when the thoracolumbar spine is included in instrumented fusion.

Objective : The purpose of this study was to evaluate the efficacy and safety of the surgical treatment for lumbar spinal stenosis in elderly patients. Methods : The authors reviewed the medical records of 49 patients older than 65 years of age with lumbar spinal stenosis who underwent surgical treatment from January 2002 to December 2004 in our institute. Results : Average age of patients was 70 years old [32 women, 17 men]. Twenty-four patients had chronic medical disorders. All patients were operated under the general anesthesia of these, 29 patients underwent decompressive laminectomy and decompressive laminectomy with instrumentation and fusion in 20 patients. The mean operation time was 193.5 minutes, mean estimated blood loss was 378cc and mean postoperative hospital stay length was 15.3 days. The mean follow-up duration was 11.9 months. The evaluation of outcome was assessed by Macnab classification. At first month after operation, the outcome showed excellent in 7 [14.3%]. good in 35 [71.4%], fair in 5 [10.2%], and poor in 2 [4.1%]. And at 6 months after operation, 17 patients were lost in follow-up, the outcome showed excellent in 4 [12.5%], good in 25 [78.1%], fair in 3 [9.4%], and no poor cases. There was no significant difference between outcome of laminectomy alone and that of laminectomy with fusion. Six patients [12.2%] experienced postoperative complications which included wound infection [3], nerve root injury [1], disc herniation [1], and reoperation due to insufficient decompression [1]. There were no deaths related to operation. Conclusion : We conclude that the surgical treatment for lumbar spinal stenosis in elderly patients can provide good results with acceptable morbidity when carefully selected. In addition, decision on lumbar spinal fusion should not be against solely on advanced age.

Objective : The purpose of this study was to describe a surgical technique of axillary approach of percutaneous endoscopic interlaminar discectomy for L5-S1 disc herniation and its preliminary results. Methods : From July 2002 to September 2003, 101 patients with lumbar radiculopathy due to L5-S1 disc herniation, who were treated by percutaneous interlaminar endoscopic discectomy, were retrospectively reviewed. There were 57 males and 44 females with a mean age of 44.8 years [range, 18 to 62 years]. The surgery consisted of needle insertion into the epidural space via the interlaminar space, sequential dilatation, and endoscopic discectomy through the axillary area of the S1 root. Results : The mean follow-up period was 14.5 months and the average surgical time was 41 min. According to the modified Macnab criteria, 44 patients [43.6%] had excellent outcomes, 49 [48.5%] had good results and only 8 [78%] had fair or poor outcomes. Four patients had a revision microdiscectomy due to incomplete removal of disc fragment. There were no major complications related to this surgical approach. Conclusion : Axillary approach of percutaneous endoscopic interlaminar discectomy is safe and effective procedure for the treatment of L5-Sl disc herniation. It combines the advantages of MED and conventional percutaneous endoscopic discectomy.

This report describes a case of spinal nerve root compression due to an acute inflammatory granuloma after lumbar surgery. A 39 year-old man with a history of increasing back pain with a 3-week duration was diagnosed with a herniated intervertebral disc (HIVD). The diagnosis of a HIVD was confirmed by magnetic resonance imaging (MRI) with indications for surgery. A discectomy and a partial laminectomy was performed and the symptoms were alleviated immediately after surgery for a five-day period. However, a slowly progressing pain was subsequently noted along a different dermatome. There was no pain relief despite the patient being given pharmacological treatments, combined with an epidural steroid injection. The follow up MRI images showed severe compression of the nerve roots by a epidural lesion. Another procedure was performed 17 days after the initial operation. The lesion responsible for the compression of the nerve roots was found to be an acute inflammatory granuloma. The pain was relieved after the second procedure and there were no other symptoms or neurological problems. This case is remarkable in that a granuloma formed relatively quickly and grew to such a size that it was able to severely compress the surrounding nerve roots.

Background: Since open Wiltse approach allows limited visualization for foraminal stenosis leading to an incomplete decompression, we report the short-term clinical and radiological results of unilateral biportal endoscopic foraminal decompression using $0^{\circ}$ or $30^{\circ}$ endoscopy with better visualization. Methods: We examined 31 patients that underwent surgery for neurological symptoms due to lumbar foraminal stenosis which was refractory to 6 weeks of conservative treatment. All 31 patients underwent unilateral biportal endoscopic far-lateral decompression (UBEFLD). One portal was used for viewing purpose, and the other was for surgical instruments. Unilateral foraminotomy was performed under guidance of $0^{\circ}$ or $30^{\circ}$ endoscopy. Clinical outcomes were analyzed using the modified Macnab criteria, Oswestry disability index, and visual analogue scale. Plain radiographs obtained preoperatively and 1 year postoperatively were compared to analyze the intervertebral angle (IVA), dynamic IVA, percentage of slip, dynamic percentage of slip (gap between the percentage of slip on flexion and extension views), slip angle, disc height index (DHI), and foraminal height index (FHI). Results: The IVA significantly increased from $6.24^{\circ}{\pm}4.27^{\circ}$ to $6.96^{\circ}{\pm}3.58^{\circ}$ at 1 year postoperatively (p = 0.306). The dynamic IVA slightly decreased from $6.27^{\circ}{\pm}3.12^{\circ}$ to $6.04^{\circ}{\pm}2.41^{\circ}$, but the difference was not statistically significant (p = 0.375). The percentage of slip was $3.41%{\pm}5.24%$ preoperatively and $6.01%{\pm}1.43%$ at 1-year follow-up (p = 0.227), showing no significant difference. The preoperative dynamic percentage of slip was $2.90%{\pm}3.37%$; at 1 year postoperatively, it was $3.13%{\pm}4.11%$ (p = 0.720), showing no significant difference. The DHI changed from $34.78%{\pm}9.54%$ preoperatively to $35.05%{\pm}8.83%$ postoperatively, which was not statistically significant (p = 0.837). In addition, the FHI slightly decreased from $55.15%{\pm}9.45%$ preoperatively to $54.56%{\pm}9.86%$ postoperatively, but the results were not statistically significant (p = 0.705). Conclusions: UBEFLD using endoscopy showed a satisfactory clinical outcome after 1-year follow-up and did not induce postoperative segmental spinal instability. It could be a feasible alternative to conventional open decompression or fusion surgery for lumbar foraminal stenosis.

퇴행성 추간판 질환은 전통적으로 수핵과 섬유륜의 변화에 따른 요통으로 생각되어 왔으나, 최근 연구들에서 추간판을 이루고 있는 상·하 종판의 변화가 추간판의 퇴행을 유발하고, 그 결과로 기계적 압박과 염증 반응에 의해 요통이 유발된다고 한다. 또한 최근에는 추체 골수-종판-수핵과 섬유륜을 하나의 단위로 생각하고, 그 연관성을 설명하고 있다. 종판이 손상되면 결국 추체, 수핵과 섬유륜의 퇴행성 변화를 가중시킨다. 이 과정에서 섬유륜에 가해지는 압박력이 증가하고, 염증성 매개 물질들에 의한 염증 반응이 일어나서, 동척추 신경(sinuvertebral nerve)과 기저추 신경(basivertebral nerve)이 자극을 받으면서 요통을 발생시킨다. 이런 변화가 만성화되면, 추체 내 골수에도 Modic 변화 같은 퇴행성 변화가 발생하게 된다. 결국, 퇴행성 추간판 질환은 추체 골수-종판-수핵과 섬유륜을 하나의 단위로 연관지어서 생각해야 할 필요가 있다. 그러므로 만성 요통 환자 진료 시에는 수핵과 섬유륜의 변화 소견뿐 아니라, 종판의 병변에 관심을 가질 필요가 있다고 생각된다.

Objective : Pyogenic spondylitis often results in acute neurological deterioration requiring adequate surgical intervention and appropriate antibiotic treatment. The purpose of this study was to conduct an analysis of the clinical effect of continuous irrigation via laminotomy in a series of patients with pyogenic spondylitis in thoracic and lumbar spine. Methods : The authors conducted a retrospective investigation of 31 consecutive patients with pyogenic thoracic and lumbar spondylitis who underwent continuous irrigation through laminotomy from 2004 to 2008. The study included 22 men and 9 women, ranging in age from 38 to 78 years (mean 58.1 years). The average follow-up duration was 13.4 months (range, 8-34 months). We performed debridement and abscess removal after simple laminotomy, and then washed out epidural and disc space using a continuous irrigation system. Broad spectrum antibiotics were administered empirically and changed according to the subsequent culture result. Clinical outcomes were based on the low back outcome scale (LBOS), visual analogue scale (VAS) score, and Frankel grade at the last follow-up. Radiological assessment involved plain radiographs, including functional views. Results : Common predisposing factors included local injection for pain therapy, diabetes mellitus, chronic renal failure, and liver cirrhosis. Causative microorganisms were identified in 22 cases (70.9%) : Staphylococcus aureus and Streptococcus spp. were the main organisms. After surgery, LBOS, VAS score, and Frankel grade showed significant improvement in most patients. Spinal stability was maintained during the follow-up period, making secondary reconstructive surgery unnecessary for all patients, except one. Conclusion : Simple laminotomy with continuous irrigation by insertion of a catheter into intervertebral disc space or epidural space was minimally invasive and effective in the treatment of pyogenic spondylitis. This procedure could be a beneficial treatment option in patients with thoracolumbar spondylitis combined with minimal or moderate destructive change of vertebrae.
