Background: Breathing is the essential step of Pilates exercise and can be used to activate core muscles. Although the effects of breathing exercise on pain, breathing muscles, and cervical posture have been extensively studied, little is known about the impact of Pilates breathing on spinal posture and alignment. Purpose: To determine the effect of 3D-Pilates breathing exercise on spinal curvature and alignment of healthy adults during corrected to normal alignment. Design: One group pre-post test design Methods: Eighteen participants were given a 3D-pilates breathing exercise twice a week (20 minutes per session) for three weeks and warmed up for 10 minutes before each exercise session. To examine spinal curvature and alignment of each subject, this study used radiation free rasterstereography (Formetric III, Germany). Paired t-test and Wilcoxon signed rank test were performed to determine the difference between pre and post exercise. Results: There were statistically significant differences in height (p<.001), kyphosis angle (p<.05), trunk imbalance (p<.05), kyphotic apex (p<.01), cervical fleche (p<.05), pelvic tilt (p<.01), and lateral deviation (p<.05) between before and after 3D Pilates breathing exercise. However, there was no significant difference in lordosis angle. Conclusions: The study results indicated that three week 3D-pilates breathing exercise program could be presented as an effective rehabilitation method for improving spinal curvature and alignment.

Objective : Lumbar spinal instability occurs when normal biomechanics support in lumbar vertebrae interrupted. Despite the recent enthusiastic studies, the precise radiological assessment has not been fully established, yet. Therefore, we carefully studied our cases to analyze the radiologic findings in lumbar spinal instability. Patients and Methods : We have put together radiological analysis and assessment based on 38 patients who have been diagnosed and treated for lumbar spinal instabilities from June 1994 to December 1998, Patients who have been diagnosed and treated for trauma were excluded from study. Results : The outcomes are as follows : 1) Lumbar lordotic curve was statistically significant in unstable group by 23.7, compared to the control group ($17.0^{\circ}$). 2) According to the resting x-ray, sagittal plane angulation measured on unstable group was $21.1^{\circ}$, control group $18.0^{\circ}$. Therefore unstable group was noticeably higher(p<0.01). 3) According to the resting x-ray sagittal plane displacement, unstable group had 4.3mm, the comparison had 1.2mm. Therefore measurement from the unstable group were significantly higher(p<0.01). 4) According to stress view, sagittal plane translation was 4.1mm for the unstables and 2.7mm for the comparisons. Therefore unstables were noticeably higher(p<0.01). 5) According to stress view, sagittal plane rotation was $15.1^{\circ}$ at L3-4, $22.0^{\circ}$ at L4-5, $27.9^{\circ}$ at L5S1 for the unstable group and $11.3^{\circ}$, $18.1^{\circ}$, $21.0^{\circ}$ each for the comparison. 6) Facet angle for unstable group, left $29.3^{\circ}-61.5^{\circ}$, right $24.4^{\circ}-63.2^{\circ}$ and the mean for each are $43.1^{\circ}$, $47.2^{\circ}$. The difference between left and right facet angle was $3.5^{\circ}-20.7^{\circ}$ and the mean value $15.3^{\circ}$. Facet angle for the comparisons for the left was $29.3^{\circ}-59.5^{\circ}$, right was in between $25.7^{\circ}-64.5^{\circ}$ range and the each mean are $44.9^{\circ}$ and $47.6^{\circ}$. Also, the difference between left and right facet angle was $4.1^{\circ}-9.3^{\circ}$ and the average was $17.1^{\circ}$. The average and the difference between the left and right angle are found not to have statistic necessity for both unstable and stable measurements(p>0.01). 7) 19 patients were found to have vacuum facet phenomenon among unstable group etc. results were collected. Conclusion : According to above results, we attempted to prepare the application to the patient of radiological analysis and assessment for lumbar spinal instability early checkup.

PURPOSE: The Fukuda test can be used at home and in school to diagnose scoliosis at an early stage and prevent serious curvature of the spine. This study aimed to use the Fukuda test to detect scoliosis. An additional aim was to invoke the national interest in imbalanced postures and habits, which result in scoliosis, by providing data obtained in periodic assessments. METHODS: The study consisted of 35 idiopathic scoliosis patients (22 in right lumbar spinal region and 13 in the left lumbar spinal region). The distance of displacement and angle of displacement were measured following the Fukuda test. A correlation analysis was then used to examine the distance of displacement and angles of displacement and rotation with regard to the direction of the curve in scoliosis. RESULTS: There was a significant negative correlation (p<0.00) between the direction of the curve in scoliosis and the angle of displacement, but there was no correlation between the cobb's angle and distance of displacement or between the cobb's angle and angle of rotation. CONCLUSION: The Fukuda test did not capture changes in spinal curvature such as the cobb's angle, or subsequent changes in the muscles. Thus, the Fukuda test is not suited to examining the direction or status of the thoracic curve in scoliosis patients. Simple methods to objectively measure scoliosis need to be developed.

Objective : The purpose of this study is to compare the outcomes of two methods for stabilization and fusion : Postero-Lateral Fusion [PLF, pedicle screw fixation with bone graft] and Posterior Lumbar Interbody Fusion [PLIF, cage insertion] for spinal stenosis and recurred disc herniation except degenerative spondylolisthesis. Methods : Seventy one patients who underwent PLF [n=36] or PLIF [n=35] between 1997 and 2001 were evaluated prospectively. These two groups were compared for the change of interbody space, the range of segmental angle, the angle of lumbar motion, and clinical outcomes by Prolo scale. Results : The mean follow-up period was 32.6 months. The PLIF group showed statistically significant increase of the interbody space after surgery. However, the difference in the change of interbody space between two groups was insignificant [P value=0.05]. The range of segmental angle was better in the PLIF group, but the difference in the change of segmental angle was not statistically significant [P value=0.0l7]. Angle of lumbar motion was similar in the two groups. Changes of Prolo economic scale were not statistically significant [P value=0.193]. The PLIF group showed statistically significant improvement in Prolo functional scale [P value=0.003]. In Prolo economic and functional scale, there were statistically significant relationships between follow-up duration [P value<0.001]. change of interbody space [P value<0.001], and range of segmental angle [P value<0.001]. Conclusion : Results of this study indicate that PLIF is superior to PLF in interbody space augmentation and clinical outcomes by Prolo functional scale. Analysis of clinical outcomes showed significant relationships among various factors [fusion type, follow-up duration, change of interbody space, and range of segmental angle]. Therefore, the authors recommend instrumented PLIF to offer better clinical outcomes in patients who needed instrumented lumbar fusion for spinal stenosis and recurred disc herniation.

Objective : Percutaneous vertebroplasty (VP) can provide immediate stabilization in pathologic fractures of spinal tumors. However, long term follow-up data in cases of pathologic fractures are lacking. The authors report follow-up results of VP in 185 pathologic fractures of 102 spinal tumor patients. Methods : Percutaneous VP was performed at 185 vertebral bodies of 102 patients from 2001 to 2007. Retrospective analysis was done with medical records and radiological data. The change of visual analogue score (VAS), vertebral body (VB) height and kyphotic angle were measured preoperatively and on postoperative one day and at 3, 6, and 12 months. Results : The patients were composed of metastatic spine tumors (81%) and multiple myeloma (19%). Involved spinal segments were between T6 and L5. Mean follow-up period was 12.2 months. VAS for back pain was 8.24 preoperatively, 3.59 (postoperative one day), 4.08 (three months) and 5.22 (one year). VB compression ratio changed from 21.33% preoperatively to 13.82% (postoperative one day), 14.36% (three month), and 16.04% (one year). Kyphotic angle changed from $15.35^{\circ}$ preoperatively to $12.03^{\circ}$ (postoperative one day), $13.64^{\circ}$ (three month), and $15.61^{\circ}$ (one year). Conclusion : Immediate pain relief was definite after VP in pathologic compression fracture of osteolytic spinal disease. Although VAS was slightly increased on one year follow-up, VP effect was maintained without significant change. These results indicate that VP could be a safe and effective procedure as a palliative treatment of the spinal tumor patients.

본 연구는 청소년의 스마트폰 중독이 증가함에 따라 나타나는 척추 건강에 미치는 영향을 알아보고 인지강도에 따른 척추건강의 조절효과를 알아보고자 실시하였다. 모든 대상자는 스마트 폰 중독 진단 척도, 경추의 전방 기울기 각도(거북목 각도), 그리고 뇌파의 인지감마피크(Cognitive Gamma-Peak)의 진폭변화량을 측정하여 스마트폰 사용 정도, 척추각도, 그리고 인지강도를 측정하였다. 그 결과 스마트폰 사용 정도가 증가할수록 척추각도는 유의하게 증가하였으며(p<.001), 인지강도가 증가할수록 척추각도는 유의하게 감소하였다(p<.01). 또한 인지강도는 스마트폰 사용정도의 상호작용을 통해서도 척추각도에 조절효과를 나타냈다(p<.05). 이러한 결과를 볼 때, 인지강도가 낮을수록 스마트폰 사용정도는 증가하며 이에 따른 척추각도도 증가함을 의미한다. 결국 이 결과는 후기 청소년들에게 인지강도가 중간인 그룹과 낮은 그룹에서 스마트폰 사용 정도가 높아질수록 경추의 전방 기울기 각도(거북목 각도)가 더 증가한다는 것을 알 수 있다.

In this paper, we proposed the method of virtual reality-based surgical navigation to reproduce the pre-planned position and angle of the pedicle screw in spinal fusion surgery. The goal of the proposed method is to quantitatively save the surgical plan by applying a virtual guide coordinate system and reproduce it in the surgical process through virtual reality. In the surgical planning step, the insertion position and angle of the pedicle screw are planned and stored based on the virtual guide coordinate system. To implement the virtual reality-based surgical navigation, a vision tracking system is applied to set the patient coordinate system and paired point-based patient-to-image registration is performed. In the surgical navigation step, the surgical plan is reproduced by quantitatively visualizing the pre-planned insertion position and angle of the pedicle screw using a virtual guide coordinate system. We conducted phantom experiment to verify the error between the surgical plan and the surgical navigation, the experimental result showed that target registration error was average 1.47 ± 0.64 mm when using the proposed method. We believe that our method can be used to accurately reproduce a pre-established surgical plan in spinal fusion surgery.

Objective : In order to provide normal values of the pediatric sub-axial cervical spinal canal and vertebral body growth pattern using computed tomographic scans, a total of 318 patients less than 10 years old were included. Methods : The growth of the vertebral body and canal space was investigated using four different age groups. The Torg ratio (TR) was calculated and all patients were classified into a low TR group and a high TR group according to a cutoff value of 1.0. To account for spinal curvature, the C3-7 angle was measured. Results : Very little axial expansion and growth in height were observed (2.9 mm and 3.4 mm, respectively), and the spinal canal increments (1.8 mm) were much smaller than the dimensions of the vertebral body. The mean TR values were $1.03{\pm}0.14$ at the C3 vertebral level, $1.02{\pm}0.13$ at C4, $1.05{\pm}0.13$ at C5, $1.04{\pm}0.13$ at C6, and $1.02{\pm}0.12$ at C7 in all patients. The mean sub-axial angle (C3-7) was $7.9{\pm}10.6^{\circ}$ (range: $-17-47^{\circ}$). Conclusion : The upper sub-axial spinal canal continuously increased in size compared to the lower sub-axial spine after 8 years of age. Considerable decrements in the TR was found after late childhood compared to younger ages. Generally, there were no significant differences between boys and girls in vertical length of the cervical vertebrae. However, the axial dimension of the vertebral body and the spinal canal space varied according to gender.
