Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term "degenerative cervical myelopathy (DCM)" was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patient

STUDY DESIGN: A nationwide population-based study. PURPOSE: Osteoporotic vertebral compression fracture (OVCF) is a major public health issue. This study examined the incidence and management trends of OVCF in South Korea. OVERVIEW OF LITERATURE: The incidence rates, management trends, and patterns of OVCF differ in different parts of the world. The age-standardized OVCF incidence rate in 2015 was higher in the United States and Asia than in Europe. METHODS: A nationwide database (2012-2016) acq

STUDY DESIGN: Population-based study. From 2008 to 2017, data from the national database of the Korean Health Insurance Review & Assessment Service were analyzed. The national insurance system and all medical expense bill data of the entire population are included in the database. OBJECTIVE: The aim of this study was to elucidate the incidence and management trends of metastatic spinal tumors in South Korea. SUMMARY OF BACKGROUND DATA: The spine is the most common location of bone metastases. Ho

In a Korean population, the normal cervical disc height was about 5.0 mm and the normal facet joint space was 1.4 mm. Disc height ratio can reliably identify normal cervical disc height in patients with mild degeneration. Patient height was positively correlated with disc height and facet joint space. Thus, when selecting a cervical implant, surgeons should consider patient height as well as estimated normal disc height.

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: To investigate the radiographic and clinical effectiveness of surgical treatment using a posterior-only approach, as compared with a combined antero-posterior approach, in patients with infective spondylodiscitis. SUMMARY OF BACKGROUND DATA: Spondylodiscitis is the most common infectious disease of the spine. There is currently no consensus over the surgical approach, use of bone graft, and type of instrumentation for optimal treatment of

This case series investigated the efficacy and optimal dose of Escherichia coli-derived bone morphogenetic protein-2 (E.BMP-2) as a bone graft substitute for additional posterolateral spinal fusion, accompanying interbody fusion procedures, for treating lumbar degenerative spinal stenosis. This study focused on the optimal dose for each segment and the efficacy of E.BMP-2 as a substitute for autogenous iliac bone graft.Ten patients were enrolled from January 2015 to December 2015, and underwent

The Bosworth ankle fracture-dislocation is a rare injury and is often irreducible because of an entrapped proximal fragment of the fibula behind the posterior tibial tubercle. Repeated closed reduction or delayed open reduction may result in several complications. Thus, early open reduction and internal fixation enable a better outcome by minimizing soft-tissue damage. We report on a 27-year-old man who underwent open reduction and internal fixation after multiple attempts at failed closed reduc
