Objective : The purpose of this study is to investigate the clinical results of anterior and posterior stabilization by one stage posterolateral approach for the unstable fracture of thoracolumbar and lumbar spine. Methods : By posterolateral approach with curved skin incision, unilateral facet and pedicle were removed. Through this route, corpectomy was performed, and then this space was replaced with mesh cage filled up with autologous bone graft. Both side pedicle screw fixation was followed to upper and lower levels. Results : Six of seven patients of this study showed neurological improvement. The other one patient showed no neurological change. One patient had postoperative infection, another patient had postoperative kyphosis. The other patient had epidural hematoma on operation site after surgery. And all patinets on this study made to have spinal stability except one patient happened postoperative kyphosis. Conclusion : In the unstable fracture of thoracolumbar and lumbar spine, one stage anterior and posterior stabilization and fusion by posterolateral approach seems to be an effective procedure, if we have more care and supplementation.

The purpose of this study was to investigate the effect of isoflavone supplementation using soymilk on bone mineral density in underweight college women aged 19-22 years with lower than average bone mass. The bone mineral density (BMD) of the lumbar spine and femoral neck of a number of underweight (BMI < 20) college women was measured. From this group, 33 subjects whose T-score value was below -1 were selected. Anthropometric measurements, dietary recall and BMD were measured before the study began and at the end of the 10th week. The 33 subjects were given 400 ml of soymilk containing 60 mg of isoflavones daily for 10 weeks. After 12 weeks at the end of 10 weeks treatment, the BMD of the subjects was reassessed. The average age of the subjects was 21.1 yrs. At the baseline, average height, weight, and BMI of the subjects were 161 cm, 49.1 kg, 18.8 kg/$m^2$, respectively. Mean daily intake of energy and protein was 1637.2 kcal and 61.2 g, respectively. Mean dietary isoflavone intake was 17.4 mg. Despite the 400 ml soymilk supplementation, there was no significant change in nutrient intake after the 10-week treatment. However, there were significant increases in lumbar spine and femoral neck BMD. After the study, the BMD of the subjects' spine and femoral neck was lower than that before the study. In conclusion, soymilk intake was associated with a significant increase in the BMD of the lumbar spine and femoral neck in underweight college women with lower than average bone mass.

본 연구는 요추 지지대가 노인의 머리와 목 자세에 미치는 영향을 분석하고자 하였다. 20명의 신체 건강한 노인(평균 나이 71.32세)을 대상으로 측정하였으며, 앉은 자세에서 모니터를 시청하는 동안 요추만곡을 요추 지지대 사용 유무에 따라 조절하였다. 측정은 측면에서 사진을 촬영하였다. NIH ImageJ 1.32 프로그램을 사용하여 상부경추 굴곡 각도와 하부경추 굴곡 각도를 측정하였고 분석은 대응 t 검정을 사용하였다. 그 결과, 상부경추 굴곡 각도와 하부경추 굴곡 각도는 요추 지지대 적용 여부에 따라 유의한 차이가 있었다. 상부경추 평균 굴곡 각도는 요추 지지대 적용할 때가 적용하지 않을 때보다 약 $2.83^{\circ}$ 증가하였다(p<0.005). 하부경추 평균 굴곡 각도 역시 요추 지지대를 적용할 때 약 $4.44^{\circ}$ 증가되었다(p<0.0001). 이는 요추 지지대를 적용하였을 때 상부경추와 하부경추 굴곡을 증가시킴으로 머리와 목 자세에 좋은 영향을 주는 것을 의미한다. 따라서 노인의 머리와 목 자세 개선시 요추만곡 조절을 고려해야 할 것이다.

Many recent studies suggest that the posterior dynamic stabilization(PDS) can be a more physiologically-relevant alternative to the rigid fixation for the patients suffering from low back pain. However, its biomechanical effects or clinically proven efficacies still remain unknown. In this study, we evaluated kinematic behaviors of the lower lumbar spine with the PDS system and then compared to those of the rigid fixation system using finite element (FE) analysis. A validated FE model of intact lumbar spine(L2-L5) was developed. The implanted model was then constructed after modification from the intact to simulate two kinds of pedicle screw systems (PDS and the rigid fixation). Hybrid protocol was used to flex, extend, laterally bend and axially rotate the FE model. Results showed that the PDS systems are more flexible than rigid fixation systems, yet not flexible enough to preserve motion. PDS system allowed $16.2{\sim}42.2%$ more intersegmental rotation than the rigid fixation at the implanted level. One the other hand, at the adjacent level it allowed more range of motion ($2.0%{\sim}8.3%$) than the rigid fixation. The center of rotation of the PDS model remained closer to that of the intact spine. These results suggest that the PDS system could be able to prevent excessive motion at the adjacent levels and restore the spinal kinematics.

Background: Multifidus muscle stiffness decreases in patients with lumbar intervertebral disk herniation; however, age-related changes in humans have not been reported. Objectives: The reliability of ultrasound shear wave elastography in dogs, and changes in the shear elastic modulus of the thoracolumbar multifidus muscle with aging in dogs, were investigated. Methods: Twelve beagle dogs were divided into 2 groups based on the age of onset of intervertebral disk herniation: young (aged not exceeding 2 years; 1.3 ± 0.6 years old, n = 5) and adult (4.9 ± 1.2 years old, n = 7). The shear elastic modulus of the multifidus muscle, from the thirteenth thoracic spine to the fourth lumbar spine, was measured using ultrasound shear wave elastography. The length, cross-sectional area and muscle to fat ratio of the multifidus muscle, and the grade of intervertebral disk degeneration, were assessed using radiographic and magnetic resonance imaging examinations. Results: The length and cross-sectional area of the multifidus muscle increased caudally. In the young group, the shear elastic modulus of the multifidus muscle of the thirteenth thoracic spine was less than that of the third lumbar spine. In the adult group, the shear elastic modulus of the multifidus muscle of first and third lumbar spine was lower than that of the same site in the young group. Conclusions: Ultrasound can be used to measure shear wave elastography of the thoracolumbar multifidus in dogs. If the multifidus muscle stiffness decreases, we should consider age-related change.

Background: The purpose of this study was to investigate the relationship between the spine and the flat-foot, the stability and the alignment of the posture of the neck to prevent the alignment of the ankle joint operation and the lower back flexibility of the lumbar region according to the type of treatment using active stretching of the triceps, back pain, and to see how they affect weight bearing differences. Methods: The subjects of this study were 24 chronic low back pain patients. They were randomly divided into experimental group and control group. In the experimental group, ankle joint mobilization and active scraping of triceps were performed three times a week for a total of 6 weeks. The control group was performed in the same way without articulation. The range of flexion and extension motion of the lumbar spine and pain degree and difference of weight-bearing were measured before and after the experiment. Results: The model of ankle joint mobilization and calf muscle elongation of flat foot significantly improved the range of flexion and extension motion of the vertebrae (p<.05) and the VAS and distribution of weight-bearing were decreased in both of two groups (p<.05). In other words, the exercise and mobilization help to recover of the balance of the whole musculoskeletal, the vertebrae. Conclusions: The active exercise of the triceps muscle of the lower leg in this study It affects the flexibility of the lumbar spine, the pain and the difference in the weight support of the lower extremities, when we performed ankle joint mobilization for exercise and cramping, pain and the difference in weight support between the two lower limbs.

Synovial cysts are recognized as an uncommon cause of radicular and myelopathic symptoms. They are most frequently found in the lumbar region. The cervical spine or cervicothoracic junction is a rare location for a degenerative intraspinal synovial cyst as compared with the lumbar spine. At given cervical spinal levels, synovial cysts probably share clinical features with disc herniation and stenosis. However, the pathogenesis of synovial cysts remains still controversial. Here, we report a rare case of a synovial cyst in the lower cervical spine presented as Brown-Sequard syndrome and include a brief review of the literature. To the best of our knowledge, no previous report has been issued in the English literature on a synovial cyst presenting with Brown-Sequard syndrome. Neurologic function recovered completely after complete removal of the cyst and expansive laminoplasty.

Muscular hypertrophy is caused mainly due to myopathic disorder. But, it is also rarely produced by neurogenic disorder. A 74-year-old woman complained of right calf pain with hypertrophy for several years. Recent lumbar spine magnetic resonance imaging (MRI) showed central and lateral canal narrowing at the L4-L5 intervertebral space. Lower extremity MRI revealed fatty change of right medial head of the gastrocnemius and soleus, causing right calf hypertrophy. Electrodiagnostic examinations including electromyography and nerve conduction velocity testing demonstrated $5^{th}$ lumbar and $1^{st}$ sacral polyradiculopathy. Integrating all the results, the diagnosis was neurogenic muscle hypertrophy. Neurogenic muscle hypertrophy is very rare, but we recommend that clinicians consider this problem when a patient complains of lower limb hypertrophy and pain.

Objectives To introduce a case of a traffic accident trauma in a patient with lumbar kyphosis and straightened lumbar curvature, where the Korean medicine treatment with Chuna manual therapy (CMT) improved lumbar lordotic angle(LLA) and lower back pain. Methods Chuna manual therapy and other Korean medicine treatments; were provided to patient with a flat back posture and low back pain due to the trauma from a traffic accident. Cobb's angle to evaluate LLA and numeric rating scale (NRS) to evaluate pain were compared before and after the treatment. Results There was a significant increase in LLA to reach the normal range and a decrease in low back pain NRS after Korean medicine treatment with CMT for 9 days of admission treatment and 3 weeks of outpatient treatment. Conclusions This study suggests that Korean medicine treatment, including CMT, may improve low back pain as well as LLA of straightened lumbar curvatures in patients.
