This study was peformed to assess the relationships among bone mineral density (BMD), Physiological characteristics and lifestyle factors in 61 premenopausal working women aged 30∼49 y in Busan. The BMDs of the lumbar spines (Ll∼L4), femoral necks (FN), ward's triangles (WT) and trochanters (TC) were measured by dual energy X-ray absorptiometry. Data for physiological characteristics and physical activity was assessed by questionnaire and usual intakes of coffee, green tea, alcohol, Coca cola by food frequency questionnaire. The BMDs of L14, FN, WT and TC were 1.02 g/$\textrm{cm}^2$, 0.76 g/$\textrm{cm}^2$,0.69 g/$\textrm{cm}^2$ and 0.66 g/$\textrm{cm}^2$respectively The BMD of FN was assessed as osteopenia by T-score. The BMD of WT was positively correlated with age of monarch (p<0.05) and the BMD of Ll4 was positively correlated with delivery number (p<0.05). The BMD of Ll4 was positively correlated with hours of outdoor activity per weekend and week (p<0.05, p<0.05). The BMDs of FN and WT (p<0.05, p<0.05) were positively correlated with intake of green tea per month and the BMD of FN (p<0.05) was positively correlated with intake of wine per month. But the BMD of Ll (p<0.05) was negatively correlated with intake of Coca cola per month. So nutritional education for increasing hours of outdoor activity and decreasing intake frequency of beverage contributing to diminishment of bone mineral density is needed for premenopausal working women to prevent osteoporosis.

Ten patients with a thoracolumbar spine fractures were treated with Kaneda internal fixation device through anterolateral approach during last 1 year. In all cases, spinal decompression, internal instrument fixation and hone fusion with rib were performed. No patient showed neurological deterioration after surgery and 6(60%) patients improved postoperatively with entering the next Frankel subgroup. Follwo-up patient evaluation showed the correction of the fracture deformity with good bony fusion, but 3 patient arc remained back pain. According to above results we concluded that anterolateral internal fixation combined with hone fusion using rib was good mechanical stability and decompression of protruding ventral bone fragments above conus medullaris level.

The Purpose of this study was to find out the effects of frequency and intensity of transcutaneous electrical nerve stimulation(TENS) on the patients with chronic low back pain. The subjects were 32 patients with chronic low back pain average age 39.19 (${\pm}12.96$)years. The duration of chronic low back pain was 8.57 (${\pm}3.07$)months. The treatments were given 15 minutes once a day five a week for two weeks. to low back. Lumbar range of motion(ROM) and Oswestry Disabilitv Index(ODI)) was evaluated before and after TENS application. Each group was compared using Wilcoxon Mann-Whitney test. The results were as followings: Each group showed significant effect. High intensity group showed more effect in low frequency group. High intensity group showed more effect in high frequency group. Therefore, the high intensity can be used more effectively with high frequency for treating chronic low back pain.

척추경 나사못을 이용한 요추 유합술은 가장 보편적으로 사용되어지는 수술적 치료 방법이다. 과거 여러 연구들에서 이러한 척추 유합술의 임상적 우수성은 이미 입증 되었으며, 척추경 나사못은 시술 부위의 운동을 완전히 제한함으로써 높은 유합율을 얻을 수 있으나, 상대적으로 인접 분절의 조기 퇴행성 변화의 요인 중 하나로 보고되고 있다. 따라서 본 연구에서는 유한요소해석 방법을 이용하여 척추경 나사못 시술에 따른 척추체의 운동범위 및 인접 분절 추간판의 스트레스 증가량을 계산하였고, 척추경 나사못 모델과 유합 후 나사못 제거에 따른 모델 또 시술하기 전 정상모델과 비교하여 생체 역학적 측면에서 분석하여 척추경 나사못을 이용한 요추 유합술 후, 척추경 나사못의 제거의 임상적 효과와 그 이론적 근거를 제시하고자 한다.

Purpose: This study examined the utility of preliminary magnetic resonance imaging (MRI) measurements in the ultrasound-guided L4 selective nerve root block. Materials and Methods: As a retrospective study, 71 patients, who met the criteria for outpatient visits from March 2016 to December 2017, were included. From March 2016 to February 2017, 31 patients who underwent an L4 nerve root block without MRI were classified as group A, and 40 patients who underwent an L4 nerve root block through MRI measurements from March 2017 to December 2017 were classified as group B. Group A was injected under ultrasound-guidance through the pararadicular approach without a pre-interventional MRI evaluation, and group B was injected under ultrasound-guidance according to the preliminary MRI measurements. The results were assessed using the numeric rating scale scores before, three hours, and two, six, and 12 weeks after the procedure. Results: At three hours after the procedure, the proportion of patients better than good results were 51.6% in group A and 67.5% in group B. At two weeks after the procedure, the proportion of patients with better than good results were 48.4% and 70.0% in groups A and B, respectively; 58.1% and 62.5% of patient of groups A and B, respectively, showed better than good results after six weeks. In 12 weeks after the procedure, the results of group A and B were 67.7% and 62.5%, respectively. At three hours and two weeks after the procedure, group B showed significant symptom improvement than group A (p<0.05). The procedures were repeated 2.8 and 1.7 times in groups A and B, respectively, between two and six weeks for satisfactory pain relief (p<0.05). Conclusion: A pre-interventional MRI evaluation might improve pain relief within the initial two weeks after ultrasound-guided L4 selective nerve root block by improving the success rate of the procedure.

The Many patients who have lumbar instability(LI) could make a different trunk movement pattern by reduction of their respiratory function and altered breathing pattern. This study was conducted to investigate the change in the thoracoabdominal usage rate(TAUR) on three circumference lines(axillary, xiphoid junction, 10th rib) during the resting and forced breathing (RB and FB) after respiratory pattern correction(RPC) exercises in patients with LI. 15 patients in the experimental group performed RPC exercises, and 15 patients in the control group conducted lumbar stabilization exercises. Before the intervention, both groups had a significant difference in the usage rate among the three thoracoabdominal lines during the RB and FB(p<.05). After the intervention, the experimental group was seen no significant difference in the usage rate among the three lines during the RB(p>.05) and exhibited significant differences in the usage rate between the two thoracoabdominal lines during the FB(p<.05). The RPC exercises might improve the trunk movement patterns by restoring the respiratory patterns. We suggest that the RPC can apply in the re-education and reinforcement process at the reha-program for LI patients.

Purpose: To analyze the risk factors for posterior migration of a single cage after transforminal lumbar interbody fusion (TLIF). Materials and Methods: This study was conducted retrospectively on 48 patients (60 discs) who were followed-up for 1 year after TLIF from January 2015 to January 2017. The patients were divided into two groups: group 1 containing 16 patients (17 discs) with cage migration and group 2 containing 32 patients (43 discs) without it. Information related to cage migration, such as the demographic factors, shape of disc, level and location of the cage inserted, and disc height change, was acquired from the medical records and radiologic images, and the possibility for generating posterior migration of cage was evaluated statistically. Results: The demographic factors and cage-inserted level were similar in the two groups (16 patients in group 1, 32 patients in group 2). In the migration group, number of patients with a pear-type disc, 9 patients, was significantly larger; the disc height change, 1.8 mm, was significantly smaller; and the cage was located frequently on non-center in the anteriorposterior view and center in the lateral view in 9 and 15 out of 16 patients, respectively. Conclusion: A pear-type disc shape, small disc height change, cage with non-center on the anteriorposterior view and non-anterior on the lateral view are the risk factors for posterior migration. These factors are important for preventing posterior migration of the cage.

Purpose: The need for revision fusion surgery after spinal fusion has increased. A revision rod that connects to the previous rod was newly developed for revision surgery. The purpose of this study was to analyze the clinical and radiological results after spinal fusion revision surgery using revision rods. Materials and Methods: Twenty-one patients who underwent revision fusion surgery after spinal fusion in two university hospitals with minimum 1 year follow-up were reviewed. This study assessed 16 cases of adjacent-segment disease, four cases of thoracolumbar fracture, and one case of ossification of ligament flavum. The Oswestry Disability Index (ODI) and numerical rating scale (NRS) were evaluated as clinical outcomes, and the union rate, lordosis or kyphosis of the revision level, lumbar lordosis, T5-12 kyphosis, and proximal junctional kyphosis angle were evaluated as the radiological outcomes. Results: The average ODI was 54.6±12.5 before surgery and improved to 29.8±16.5 at the final follow-up. The NRS for back pain and leg pain was 5.0±1.7 and 6.4±2.0 before surgery, which changed to 2.9±1.6 and 2.9±2.2 at the final follow-up. Lumbar lordosis was 18.1°±11.9° before surgery and 21.1°±10.3° at the final follow-up. Proximal junctional kyphosis was 10.8°±10.1° before surgery, and 9.2°±10.5° at the final follow-up. These angles were not changed significantly after surgery. Bony union was successful in all cases except for one case who underwent posterolateral fusion. Conclusion: Revision surgery using a newly developed revision rod on the thoracolumbar spine achieved good clinical outcomes with successful bony union. No problems with the newly developed revision rod were encountered.

Purpose We retrospectively evaluated the technical success rate and long-term efficacy of fluoroscopy-guided synovial cyst rupture followed by an intra-articular steroid injection at the post-laminectomy lumbar facet. Materials and Methods We selected subjects who had undergone a fluoroscopy-guided synovial cyst rupture with simultaneous intra-articular steroid injection within 6 months of MRI and demonstrated a symptomatic facet joint synovial cyst at the level of a previous lumbar laminectomy. Fourteen patients were enrolled, and we determined whether cyst rupture and symptom improvement were achieved after each procedure. The degrees of symptom improvement were categorized into 4: 1) symptoms improved (30% or more reduction, based on pre-procedural and post-procedural Numerical Pain Rating Scale scores), 2) symptoms not improved, 3) patient underwent surgery after injection, and 4) loss of follow-up. Results The success rate of percutaneous synovial cyst rupture decreased with repeated procedures (62.5% for the first procedure and 0% to 33.3% for additional procedures). However, 80% of the patients had symptom improvement with the procedures, overall. The surgery rate was 14.3% in 14 patients. Conclusion For patients with post-laminectomy symptomatic lumbar facet joint synovial cysts, fluoroscopy-guided synovial cyst rupture with intra-articular steroid injection may be an effective and less invasive treatment before considering a surgical approach.
