Lumbar degenerative disease is a common problem in an aging society. Oblique lateral interbody fusion (OLIF) is a minimally invasive surgical (MIS) technique that utilizes a retroperitoneal antepsoas corridor to treat lumbar degenerative disease. OLIF has theoretical advantages over other lumbar fusion techniques, such as a lower risk of lumbar plexus injury than direct lateral interbody fusion (DLIF). Previous studies have reported favorable clinical and radiological outcomes of OLIF in various

The large single-institution prospective cohort of the present study showed favorable clinical outcomes following oblique lateral interbody fusion for lumbar degenerative disease, even in spinal stenosis without spondylolisthesis and instability.

본 논문에서는 먼저 네트워크와 네트워크 분석 방법을 자세히 소개하였다. 이러한 소개에 뒤이어 네트워크 분석방법의 국제정치학적 적용의 시도로 서, 1950년부터 2002년까지의 국제체제에 존재하 는 모든 국가 간에 이루어진 군사무기 이전의 자 료 (SIPRI Arms Transfers Database)를 사용하 여 50여 년간의 군사무기 네트워크에 대한 고찰을 국제정치학계에서는 처음으로 시도하였다. 본 연구 는 국제체제 차원에서의, 그리고 아시아 지역에서 의 지난 50여 년간의 군사무기 네트워크 구조와 주요행위자들에 대하여 분석하였다. 본 연구에서의 네트워크 분석의 결과들을 간단히 정리하면 다음 과 같다. 첫째, 국제체제 차원에서나 아시아지역 차 원에서의 군사무기 이전의 네트워크는 1950년부터 2002년까지 몇몇 주요 행위자들에 의해 지배되어 오고 있다. 둘째, 이러한 몇몇 행위자들의 무기이전 네트워크 지배 경향은 국제체제 차원에서보다 아 시아지역에서 미세하지만 더 강력히 이루어져

Indirect decompression showed lower odds of developing ASDeg and undergoing reoperation for ASDeg after lumbar interbody fusion surgery in this meta-analysis. However, the limited number and quality of the included studies should be considered when interpreting the results.

Availability of remaining options for systemic treatment is an important factor to consider when deciding on surgical treatment for spinal metastasis.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of unknown etiology that commonly affects adolescents, imposing significant socioeconomic burdens. Effective management necessitates a comprehensive approach that takes into account multiple factors, including growth potential and psychological issues. Despite significant advancements in AIS management, several questions regarding optimal treatment strategies persist. Recent technological advancements are transforming the tre

To compare total en bloc spondylectomy (TES) with stereotactic ablative radiotherapy (SABR) for single spinal metastasis, we undertook a single center retrospective study. We identified patients who had undergone TES or SABR for a single spinal metastasis between 2000 and 2019. Medical records and images were reviewed for patient and tumor characteristics, and oncologic outcomes. Patients who received TES were matched to those who received SABR to compare local control and survival. A total of 8

Biportal endoscopic spine surgery (BESS) is minimally invasive and therefore benefits both surgeons and patients. However, concerning complications include dural tears and neural tissue injuries. In this study, we aimed to develop a deep learning model for neural tissue segmentation to enhance the safety and efficacy of endoscopic spinal surgery. We used frames extracted from videos of 28 endoscopic spine surgeries, comprising 2307 images for training and 635 images for validation. A U-Net-like

Molecular target therapies have markedly improved the survival of non-small cell lung cancer (NSCLC) patients, especially those with epidermal growth factor receptor (EGFR) mutations. A positive EGFR mutation is even more critical when the chronicity of spinal metastasis is considered. However, most prognostic models that estimate the life expectancy of spinal metastasis patients do not include these biological factors. We retrospectively reviewed 85 consecutive NSCLC patients who underwent pall

Engineering a material with nanoparticles is an attractive strategy to achieve unexpected superior features of materials. Here, we explore smart polymeric composite foams made of carbon nanotubes (CNTs) and a shape memory polyurethane (SMPU) that can be heated with microwaves. The CNTs/SMPU composite foams were fabricated by using a porogen leaching method. It turned out that the composite foams showed not only improved mechanical properties but also unique thermal properties with low CNT conten
