Surgical treatment of the degenerative disc disease has evolved from traditional open spine surgery to minimally invasive spine surgery including endoscopic spine surgery. Constant improvement in the imaging modality especially with introduction of the magnetic resonance imaging, it is possible to identify culprit degenerated disc segment and again with the discography it is possible to diagnose the pain generator and pathological degenerated disc very precisely and its treatment with minimally invasive approach. With improvements in the optics, high resolution camera, light source, high speed burr, irrigation pump etc, minimally invasive spine surgeries can be performed with various endoscopic techniques for lumbar, cervical and thoracic regions. Advantages of endoscopic spine surgeries are less tissue dissection and muscle trauma, reduced blood loss, less damage to the epidural blood supply and consequent epidural fibrosis and scarring, reduced hospital stay, early functional recovery and improvement in the quality of life & better cosmesis. With precise indication, proper diagnosis and good training, the endoscopic spine surgery can give equally good result as open spine surgery. Initially, endoscopic technique was restricted to the lumbar region but now it also can be used for cervical and thoracic disc herniations. Previously endoscopy was used for disc herniations which were contained without migration but now days it is used for highly up and down migrated disc herniations as well. Use of endoscopic technique in lumbar region was restricted to disc herniations but gradually it is also used for spinal canal stenosis and endoscopic assisted fusion surgeries. Endoscopic spine surgery can play important role in the treatment of adolescent disc herniations especially for the persons who engage in the competitive sports and the athletes where less tissue trauma, cosmesis and early functional recovery is desirable. From simple chemonucleolysis to current day endoscopic procedures the history of minimally invasive spine surgery is interesting. Appropriate indications, clear imaging prior to surgery and preplanning are keys to successful outcome. In this article basic procedures of percutaneous endoscopic lumbar discectomy through transforaminal and interlaminar routes, percutaneous endoscopic cervical discectomy, percutaneous endoscopic posterior cervical foraminotomy and percutaneous endoscopic thoracic discectomy are discussed.

Objective : Lumbar discectomy is an effective treatment for lumbar disc herniation (LDH); however, up to 2-18% of patients with LDH have experienced recurrent disc herniation. The purpose of this study was to evaluate the efficacy of a novel annular closure device (ACD) for preventing LDH recurrence and re-operation compared with that of conventional lumbar discectomy (CLD). Methods : In this prospective randomized controlled trial, we compared CLD with discectomy utilizing the $Barricaid^{(R)}$ (Intrinsic Therapeutics, Inc., Woburn, MA, USA) ACD. Primary radiologic outcomes included disc height, percentage of preoperative disc height maintained, and re-herniation rates. Additional clinical outcomes included visual analog scale (VAS) scores for back and leg pain, Oswestry Disability Index (ODI) scores, and 12-item short-form health survey (SF-12) quality of life scores. Outcomes were measured at preoperation and at 1 week, 1, 3, 6, 12, and 24 months postoperation. Results : Sixty patients (30 CLD, 30 ACD) were enrolled in this study. At 24-month follow-up, the disc height in the ACD group was significantly greater than that in the CLD group ($11.4{\pm}1.5$ vs. $10.2{\pm}1.2mm$, p=0.006). Re-herniation occurred in one patient in the ACD group versus six patients in the CLD group (${\chi}^2=4.04$, p=0.044). Back and leg VAS scores, ODI scores, and SF-12 scores improved significantly in both groups compared with preoperative scores in the first 7 days following surgery and remained at significantly improved levels at a 24-month follow-up. However, no statistical difference was found between the two groups. Conclusion : Lumbar discectomy with the $Barricaid^{(R)}$ (Intrinsic Therapeutics, Inc.) ACD is more effective at maintaining disc height and preventing re-herniation compared with conventional discectomy. Our results suggest that adoption of ACD in lumbar discectomy can help improve the treatment outcome.
This paper describes a new method to create an animal model for TMJ internal derangement in the New Zealand white rabbits and the light and electron microscopical changes of posterior attachment of them. Twenty six rabbits(2.5-3.0kg), four normal and twenty two experimental, were used. The right disc of experimental animal was displaced anteriorly without sectioning the posterior attachment and tied to the zygomatic arch with nylon not to be reduced to the original position. The left TMJ was sham-operated to be compared with its right experimental one. Normal animals were sacrificed one day and eight weeks after experiment. Experimental animals were sacrificed one day, ten days, three weeks, five weeks and eight weeks after surgery respectively. They were fixed intravenously with $2\%$ glutaldehyde under general anesthesia and the samples of them were processed for light and electron microscopic examination. The purpose of this experiment is to make a suitable animal model of disc displacement without reduction for studying and understanding the cellular and morphologic events in posterior attachment of TMJ including early changes which were difficult to be observed in human TMJs. The results of this investigation suggest the following conclusions : 1. Authors induced anterior disc displacement surgically in rabbits with new method to examine histologic changes of posterior attachment. Tissue reactions of this model seem to be similar to those observed in human disc displacement. We think this animal model for anterior disc displacement may be used to explore and evaluate objectively the effects of many treatment modalities in disc displacements. 2. The animal disease model showed inflammation at early stage(one and ten days). At this stage there were mild-to-severe mononuclear inflammatory cell infiltration, numerous newly formed vessels, vessel dilatation and engormement and many fibroblasts. 3. At middle stage(three weeks), fibrosis occurred, where fibroblasts decreased in number, but their cytoplasm was profuse indicating high activity. Collagen fibers increased in number and the tissue looked more dense. 4. At late stage(five weeks and eight weeks) showed degenerative changes including perforation of posterior attachment, disintegration of collagen fiber bundles, degeneration of fibroblasts, metastatic ossification, and dystrophic calcification.

Objective : To evaluate radiographic results of anterior fusion methods in two-level cervical disc disease : tricortical autograft and plate fixation (ACDF-AP), cage and plate fixation (ACDF-CP), stand-alone cage (ACDF-CA), and corpectomy and plate fixation (ACCF). Methods: The numbers of patients were 70 with a minimum 6 month follow-up (ACDF-AP : 12, ACDF-CP : 27, ACDF-CA : 15, and ACCF : 16). Dynamic simple X-ray and computed tomography were evaluated preoperatively, postoperatively, 6 month, and at the final follow-up. The fusion and subsidence rates at the final were determined, and global cervical lordosis (GCL), cervical range of motion, fused segment angle (FSA), and fused segment height (FSH) were analyzed. Results: Nonunion was observed in 4 (25%) patients with ACDF-CA, 1 (8%) patient with ACDF-AP, 1 (4%) patient with ACDF-CP. The number of loss of FSH (%) more than 3 mm were 2 patients (16%) in ACDF-AP, 3 patients (11%) in ACDF-CP, 5 patients (33%) in ACDF-CA, and 3 patients (20%) in ACCF. The GCL was decreased with ACDF-CA and increased with others. The FSA was increased with ACDF-AP, ACDF-CP, and ACCF, but ACDF-CA was decreased. At the final follow-up, the FSH was slightly decreased in ACDF-CP, ACDF-AP, and ACCF, but ACDF-CA was more decreased. Graft related complication were minimal. Screw loosening, plate fracture, cage subsidence and migration were not identified. Conclusion: ACDF-CP demonstrated a higher fusion rate and less minimal FSH loss than the other fusions in two-level cervical disc disease. The ACDF-AP and ACCF methods had a better outcome than the ACDF-CA with respect to GCL, FSA, and FSH.

Objective : The aim of this study is to evaluate the feasibility of posterior cervical foraminotomy (PCF) for adjacent segmental disease (ASD) after anterior cervical fusion (ACF). As ACF is accepted as the standard treatment for cervical spondylosis, many studies have been conducted to evaluate the efficacy of various surgical techniques to overcome symptomatic ASD after the previous surgery. Herein, PCF was performed for the treatment of symptomatic ASD and the feasibility of the surgery was evaluated. Methods : Forty nine patients who underwent PCF due to symptomatic ASD from August 2008 to November 2017 were identified. For demographic and perioperative data, the sex, age, types of previous surgery, ASD levels, operation times, and bleeding amount were recorded. The clinical outcome was assessed using the visual analogue scale for the neck and arm, the modified Odom's criteria as well as neck disability index. Radiologic evaluations were performed by measuring disc softness, disc height, the cervical 2-7 sagittal vertical axis, cervical cobb angle, and facet violation. Results : Thirty-seven patients were enrolled in this study. The patients were divided into two groups based on the location of the pathology; paracentral (group P) or foramina (group F). Both groups showed significant clinical improvement (p<0.05). The proportion of calcified disc and facet violations was significantly larger in group F (p<0.05). The minimal disc height decrease with mild improvement on sagittal alignment and cervical lordosis was radiologically measured without statistical significance in both groups (p>0.05). Conclusion : PCF showed satisfactory clinical and radiologic outcomes for both paracentral and foraminal pathologies of ASD after ACF. Complications related to anterior revision were also avoided. PCF can be considered a feasible and safe surgical option for ASD after ACF.
Objective : In the present study, we evaluated the effect, safety and radiological outcomes of cervical hybrid surgery (cervical disc prosthesis replacement at one level, and interbody fusion at the other level) on the multilevel cervical degenerative disc disease (DDD). Methods : Fifty-one patients (mean age 46.7 years) with symptomatic multilevel cervical spondylosis were treated using hybrid surgery (HS). Clinical [neck disability index (NDI) and Visual Analogue Scale (VAS) score] and radiologic outcomes [range of motion (ROM) for cervical spine, adjacent segment and arthroplasty level] were evaluated at routine postoperative intervals of 1, 6, 12, 24 months. Review of other similar studies that examined the HS in multilevel cervical DDD was performed. Results : Out of 51 patients, 41 patients received 2 level hybrid surgery and 10 patients received 3 level hybrid surgery. The NDI and VAS score were significantly decreased during the follow up periods (p<0.05). The cervical ROM was recovered at 6 and 12 month postoperatively and the mean ROM of inferior adjacent segment was significantly larger than that of superior adjacent segments after surgery. The ROM of the arthoplasty level was preserved well during the follow up periods. No surgical and device related complications were observed. Conclusion : Hybrid surgery is a safe and effective alternative to fusion for the management of multilevel cervical spondylosis.
Objectives : The purpose of this study is to explore the trends of Chuna(manipulation) treatment on neck pain and cervical disc displacement. Methods : We set up the two searching strategies and investigated the latest clinical trials on Chuna(manipulation) therapy for Neck disorders and cervical disc herniation through PubMed search. The searched papers were analyzed and the year, journals, article types of literatures were examined. Of the articles, Randomized controlled trials(RCTs) are assessed by Jadad scale. Results : Studies on Chuna(manipulation) treatment to cervical disc herniation were very few. Articles on Chuna(manipulation) treatment to neck pain were relatively more than those of cervical disc herniation. The most frequently published journal was J Manipulative Physiol Ther. The main design of study was RCT. The limited quality assessment of RCT was conducted by Jadad scale and the average Jadad score was 1.73, which indicates low quality in terms of Jadad evaluation criteria. Conclusions : International trends of studies on Chuna therapy of cervical disease is increasingly reviewed. Although this review has several limitations, analyzing the latest trends of studies on Chuna(manipulation) treatment on neck pain and cervical disc displacement is necessary for further studies.
Purpose : The purpose of this study is to find out the effects of Joint and Muscle Mobilization applied to the patients with Degenerative Disc Disease by measuring, assessing and analyzing the changes on pain and in flexibility before and after Joint and Muscle Mobilization. Method: Surveyed from June. 2008 to July. 2009 were 10 patients suffering from DDD. Joint and muscle Mobilization were applied for 15 minutes in total. After Joint Mobilization, the Oswestry Disability Index(ODI), Visual Analogue Scale (VAS) were used to measure the degree of the pain on the patients. After Joint and Muscle Mobilization, Spinal-$Mouse^{(R)}$ were used to measure the degree of the flexibility on the patients. Result: 1. There was significant decrease in the numerical values of the VAS & ODI after Joint and Muscle Mobilization (p<0.01). 2. There was significant decrease in the degree of the pain on the patients after Joint and Muscle Mobilization (p<0.01). 3. From the analysis into DDD in the degree the pain before and after Joint and Muscle Mobilization with Paired Sample T-test, It became evident that the longer the period of treatment was, the higher the pains decreases drastically, while significant difference was shown in the flexibility and the degree of the pain (p<0.01). Conclusion: Summed up, it can be generally concluded that Joint and Muscle Mobilization is an effective treatment to rid the patients with DDD of pains safely and promptly. It is, therefore, suggested to continue and expand the study on the cure of DDD and to motivate patients. Joint and Muscle Mobilization is considered as safest and most efficient pain remedy.
Background: The first pain clinic opened in korea in 1973 at Yonsei University Hospital, however, since then the number of pain clinics has gradually increased, as has the number of patients visiting them. This increase in patient has caused concerns about the way in which pain is managed, therefore, we conducted a retrospective review of data according to the sex, age and disease in an attept to aid us in planning for the future of our pain clinic. Methods: We analyzed 1,282 new patients who had visited our pain clinic and 828 inpatients who were admitted to our pain clinic between March 2006 and February 2007. Results: The most frequent age group was in the sixties in outpatient and in the seventies in inpatient. In addition, the incidence of disease in new patients and inpatients was as follows: in new patients, lumbar herniated intervertebral disc 16.5%, hyperhidrosis 12.3%, cervical disc disorder 10.5%, acute herpes zoster 8.2%, postherpetic neuralgia 7.9%, and trigeminal neuralgia 7.0%; in admitted patients, acute herpes zoster 17.6%, trigeminal neuralgia 15.6%, lumbar herniated intervertebral disc 13.0%, postherpetic neuralgia 11.2%, hyperhidrosis 9.8%, and complex regional pain syndrome 7.0%. Conclusions: The patients visiting our pain clinic have presented with a wide variety of diseases. This improved care reflects an effort to expand our fields not only to the management of outpatients but also inpatients, as well as to the treatment of new fields of disease. In the future, We need to manage various pain patients not only in outpatients but also in inpatients to expand our field even through pain clinic is rapidly growing in Korea.
