STUDY DESIGN A new classification system for throacolumbar spine injury, Thoracolumbar Injury Classification and Severity Score (TLICS) was evaluated retrospectively. PURPOSE To evaluate intrarater and interrater reliability of newly proposed TLICS schemes and to estimate validity of TLICS's final treatment recommendation. OVERVIEW OF LITERATURE Despite(More)
STUDY DESIGN A retrospective review with clinical and radiologic assessment was conducted. OBJECTIVE To demonstrate the feasibility of posterior short segment augmentation with lamina hook and anterior lumbar interbody arthrodesis in tuberculosis of the lumbar spine by evaluating clinical results, fusion status, and sagittal angle. SUMMARY OF BACKGROUND(More)
We retrospectively evaluated 488 percutaneous pedicle screws in 110 consecutive patients that had undergone minimally invasive transforaminal lumbar interbody fusion (MITLIF) to determine the incidence of pedicle screw misplacement and its relevant risk factors. Screw placements were classified based on postoperative computed tomographic findings as(More)
Disability questionnaires are used for clinical assessment, outcome measurement, and research methodology. Any disability measurement must be adapted culturally for comparability of data, when the patients, who are measured, use different languages. This study aimed to conduct cross-cultural adaptation in translating the original (English) version of the(More)
STUDY DESIGN In vitro experiment using bone morphogenetic protein-2 (BMP-2) and human intervertebral disc (IVD) cells. OBJECTIVES To demonstrate the effect of BMP-2 on mRNAs expression (collagen type I, collagen type II, aggrecan, and osteocalcin), proteoglycan synthesis, expression of alkaline phosphatase, bone nodule formation in human IVD cells.

Catecholamines play a central role in the regulation of energy expenditure, in part stimulating lipid mobilization through lipolysis in fat cells. The beta(2)-adrenergic receptor (ADRB2) is a major lipolytic receptor in human fat cells, and a recent study has shown that common polymorphisms occurring in codons 16 and 27 of the ADRB2 gene are significantly(More)
BACKGROUND Although arthroscopic shoulder surgery is less invasive and painful than open shoulder surgery, it can often cause intra-operative hemodynamic instability and severe post-operative pain. This study was conducted to investigate the efficacy of the interscalene brachial plexus block (IBPB) on intra-operative hemodynamic changes and post-operative(More)
The very first step for keeping good dental hygiene is to employ the correct toothbrushing style. Due to the possible occurrence of periodontal disease at an early age, it is critical to begin correct toothbrushing patterns as early as possible. With this aim, we proposed a novel toothbrush monitoring and training system to interactively educate on(More)
BACKGROUND A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the(More)
A second-look endoscopy is routinely performed after endoscopic submucosal dissection (ESD) in many institutions, although the need is questionable. Additional hemostatic procedures might be necessary for the post-ESD ulcer with a high risk of bleeding. We investigated the predictive factors for post-ESD ulcers with a high risk of bleeding. Second-look(More)
