Study DesignRetrospective study.PurposeThe objective of the study is to evaluate the relationship between the detection rate of lumbar disc herniation and socioeconomic status.Overview of LiteratureIncome is one important determinant of public health. Yet, there are no reports about the relationship between socioeconomic status and the detective rate of disc herniation.MethodsIn this study, 443 cases were checked for lumbar computed tomography for lumbar disc herniation, and they reviewed questionnaires about their socioeconomic status, the presence of back pain or radiating pain and the presence of a medical certificate (to check the medical or surgical treatment for the pain) during the Korean conscription.ResultsWithout the consideration for the presence of a medical certificate, there was no difference in spinal physical grade according to socioeconomic status (p=0.290). But, with the consideration of the presence of a medical certificate, the significant statistical differences were observed according to socioeconomic status in 249 cases in the presence of a medical certificate (p=0.028). There was a lower detection rate in low economic status individuals than those in the high economic class. The common reason for not submitting a medical certificate is that it is neither necessary for the people of lower socioeconomic status nor is it financially affordable.ConclusionsThe prevalence of lumbar disc herniation is not different according to socioeconomic status, but the detective rate was affected by socioeconomic status. Socioeconomic status is an important factor for detecting lumbar disc herniation.

Purpose: To compare the results of two different surgical methods (translation vs rod derotation)in a correction of double thoracic adolescent idiopathic scoliosis (AIS) using pedicle screw instrumentation. Materials and Methods: Forty-seven patients with double thoracic AIS treated by pedicle screw instrumentation were reviewed retrospectively after a minimum follow-up of 2 years. The patients were divided into two groups; TR group (translation method, n=14) and RD group (rod derotation, n=33). There were no significant differences in the preoperative curve characteristics between the two groups. . 더욱 이 이러한 후방 기기를 척추경 나사못으로만 고정하고 그
