OBJECTIVE To investigate the relationship between bone mineral density (BMD) and sagittal spinal balance in the Korean elderly population. METHODS The retrospective study included subjects aged 60 years and above, who had whole-spine lateral radiography and dual-energy X-ray absorptiometry (DEXA) within a year's gap between each other. Sagittal vertical axis (SVA) for evaluation of sagittal s...

INTRODUCTION Lumbosacral fracture dislocation is a rare entity mainly occurred in high-energy trauma accidents. In this unstable injury, anatomical separation of the spinal column from pelvis is usually associated with severe neurological deficits. CASE PRESENTATION We described a 16-year-old girl with extremely severe axial trauma to the lumbosacral spine who presented with fracture dislocat...

dult spinal deformity is a complex pathologic procA ess with many etiologies and several mechanisms of compensation. A complete understanding of patient-specific spinopelvic alignment is required to differentiate the origin of the deformity from postural compensatory mechanisms and, ultimately, to optimize surgical correction. Specific spinopelvic parameters have been shown to be invaluable in ...

How are spinopelvic tumor resections classified? The type of pelvic resection depends on the area involved and the extent of the tumor. Problems arise when the tumor involves the sacrum and the lower lumbar spine. To obtain acceptable surgical margins in these cases, skeletal resection should extend beyond the standard hemipelvectomy (ie, the sacroiliac joint) and may include the ilium, part of...

BACKGROUND Spinopelvic reconstruction after sacrectomy for a sacropelvic tumor can result in various complications and requires a highly complicated surgical technique. We report 2 cases of pelvic reconstruction surgery using diverse U-shaped rods (USRs) after partial sacrectomy. CASE DESCRIPTION A partial sacrectomy was performed for 2 different cases: one case was a metastatic sacral tumor ...

INTRODUCTION Little data is available on the relationship between sagittal spinopelvic parameters and health related quality of life (HRQOL) in osteoporotic patients. The aim of this study was to identify relationships between spinopelvic parameters and HRQOL in osteoporosis. MATERIAL AND METHODS The patient and control groups comprised 138 osteoporotic patients and 40 controls. All underwent...

Purpose: We investigated the relationships between patient factors, including obesity, osteopenia, and scoliosis, reliability of measures spinopelvic sagittal parameters using conventional X-radiography (Xp) slot-scanning Xp devices (EOS) examined differences in interobserver measurement them.

Abstract Introduction Anterior subcutaneous internal fixator(INFIX) was proposed to treat anterior pelvic ring injury. INFIX initially designed as an alternative the external fixator, but recently its indications have been expanded, using it a definitive treatment, and multiple complications reported. Methods Retrospective study of 11 polytrauma patients with fractures treated fixator after hig...

Study Design: This is a retrospective cohort study using data from the adult spinal deformity (ASD) database of single institution. Purpose: To investigate incidence proximal junctional failure and distal (DJF) after ASD surgery with lower instrumented vertebra (LIV) at L5. Overview Literature: Spinopelvic fixation thoracic to pelvis current gold standard treatment for ASD. However, LIV L5 acce...

The treatment goals of tuberculous spondylitis are to eradicate infection and to prevent or treat instability, deformity, and neurologic deficit. The purpose of this study was to evaluate the clinical outcomes following chemotherapy with 1-stage posterior debridement, correction, and instrumentation and fusion for the treatment of lumbosacral tuberculosis with major vertebral body loss and kyph...
