In the present study, the clinical features and prognostic factors of thoracic OLF were examined in a large number of Korean patients. (More)
BACKGROUND We sought to identify preoperative factors significantly correlated with survival. We also aimed to evaluate the validity of the prognostic scores in the Tomita and Tokuhashi systems and discuss several aspects to improve the predictive accuracy of these systems. Moreover, we suggest modified criteria for selecting treatment strategies. METHODS(More)
In this paper, we propose an electronic ordering and payment system with embedded devices to improve a conventional manned ordering and payment method using a POS system for quick and easy ordering and payment. Embedded devices as thin clients of the proposed system can be placed on each table, and a user can choose a menu and can check his payment from the(More)

STUDY DESIGN Retrospective analysis. PURPOSES To introduce the mini-open lateral approach for the anterior lumbar interbody fusion (ALIF), and to investigate the advantages, technical pitfalls and complications by providing basic knowledge on extreme lateral interbody fusion (XLIF) or direct lumbar interbody fusion (DLIF). OVERVIEW OF LITERATURE(More)
STUDY DESIGN Prospective observational study. PURPOSE To introduce the techniques and present the surgical outcomes of mini-open anterior lumbar interbody fusion (ALIF) at the most caudal segments of the spine combined with lateral lumbar interbody fusion (LLIF) for the correction of adult spinal deformity. OVERVIEW OF LITERATURE Although LLIF is(More)
OBJECTIVE The cervicothoracic junction (CTJ) is a biomechanically and anatomically complex region that has traditionally posed problems for surgical access. In this retrospective study, we describe our clinical experiences of the treatment of metastatic spinal tumors at the CTJ and the results. METHODS From June 2006 to December 2011, 23 patients who(More)
A 25-year-old Korean woman was referred for uncontrolled hypertension. Laboratory examination revealed increased plasma renin activity and microscopic hematuria.
