The aim of this work was to assess whether an audit of clinical image quality could be efficiently implemented within a limited time frame using visual grading characteristics (VGC) analysis. Lumbar spine radiography, bedside chest radiography and abdominal CT were selected. For each examination, images were acquired or reconstructed in two ways. Twenty images per examination were assessed by 4...

OBJECTIVE To compare the level of agreement of quantitative morphometry of the vertebrae on lateral views of the spine using conventional X-ray and using a dual X-ray absorptiometry device (DXA) in determining the degree of wedging of vertebrae in patients with ankylosing spondylitis (AS). METHODS Thirty patients with AS underwent DXA to acquire single-energy morphometric X-ray absorptiometry...

This report describes a case in which a patient presented with hemothorax after a minimally invasive transforaminal lumbar interbody fusion (mTLIF) was performed under general anesthesia. Diagnosis of hemothorax was delayed because it is a rare complication of mTLIF. Following surgery, the patient was diagnosed with total atelectasis by a respiratory physician in the intensive care unit. The at...

STUDY DESIGN Prospective cohort study. PURPOSE To evaluate the contribution of upper and lower lumbar segments to flexion and extension of the lumbar spine in normal and diseased spines. OVERVIEW OF LITERATURE The specific contributions of upper and lower lumbar segments during flexion/extension have rarely been reported. Furthermore, no comparisons between the flexion/extension behaviors o...

Methods and materials A retrospective study of 170 asymptomatic adolescent volunteers was performed and all of them had the standing whole-spine lateral radiography. All subjects were divided into 3 groups by age: Group A (10-12 years), Group B (13-15 years), and Group C (16-18 years). Four different radiographic parameters were measured: lumbar lordosis (LL, L1-L5), thoracic kyphosis (TK, T4-T...

AIM To assess the clinical outcomes and compare the segmental range of motion (ROM) at the implanted L4-L5 level, the cranial and caudal adjacent levels, and the ROM of the whole lumbar spine after semi-rigid lumbar fusion with 2 different devices. MATERIAL AND METHODS Patients with neurogenic claudication, due to grade 1 spondylolisthesis and spinal stenosis at levels L4-L5, were treated eit...

This pilot study investigated the reliability of an inclinometer to assess lumbar spine angle in three different cycling positions, and explored the relationship between lumbar spine angle and riding position, anthropometry, bike measures and low back pain (LBP). Cyclists were recruited from two cycle clubs. Anthropometric variables and bike setup were measured before participants' bikes were s...

STUDY DESIGN Cross-sectional observational study on the relationship between the degrees of disc degeneration and sagittal alignment in asymptomatic healthy individuals. OBJECTIVE This study sought to determine whether the sagittal spine alignment subtype is related to the prevalence of lumbar disc degeneration. SUMMARY AND BACKGROUND DATA Sagittal balance and spinopelvic parameters might b...

Demonstration of an association between inflammation and spinal ankylosis has been challenging. Until the advent of MRI, prospective study was not possible due to inaccessibility of tissue. Recent studies using MRI have described an association between the presence of bone edema at vertebral corners on MRI and the subsequent development of syndesmophytes at the corresponding vertebral corners o...
