BACKGROUND The maintenance of horizontal gaze is an essential function of upright posture and global sagittal spinal alignment. Horizontal gaze is classically measured by the chin-brow vertical angle (CBVA), which is not readily measured on most lateral spine radiographs. OBJECTIVE To evaluate relations between CBVA and the slope of the line of sight, the(More)
OBJECTIVE A suggested cause of idiopathic scoliosis (IS) in children is a disequilibrium in the vestibulospinal control of trunk muscles. We sought a correlation between otolith vestibular dysfunction and IS. METHODS A recently developed test for evaluation of otolith vestibular function (off-vertical axis rotation, OVAR) was applied to 30 children with(More)
We report the results of 116 consecutive displaced extension supracondylar fractures of the elbow in children treated during the first two years after the introduction of the following protocol; closed reduction under general anaesthesia with fluoroscopic control and lateral percutaneous pinning using two parallel pins or, when closed reduction failed, open(More)
STUDY DESIGN Radiological reproducibility study. PURPOSE To assess intra and interobserver reliability of radiographic measurements for global sagittal balance parameters and sagittal spine curves, including cervical spine. Sagittal spine balance in adolescent idiopathic scoliosis (AIS) is a main issue and many studies have been reported, showing that(More)
BACKGROUND Iliac crest autograft is currently the gold standard material for spinal fusion. However, its use is limited by additional operative time, increased blood loss, and morbidity. Recently, a synthetic osteoconductive bone graft material composed of bioactive glass has been described, with high effectiveness in animal models. Its ability to achieve(More)
Unstable degenerative spondylolisthesis of the cervical spine is very rare. Slip usually occurs at the C3 on C4 or C4 on C5 levels, immediately above a stiff lower cervical spine. There are two clinical patterns: that with neurological involvement causing cervicobrachial pain or myelopathy and that with neck pain alone. The diagnosis can be made by(More)
BACKGROUND Kingella kingae, a normal component of the upper respiratory flora, is being increasingly recognized as an important invasive pathogen in young children. Genetic diversity of this species has not been studied. METHODS We analyzed 103 strains from different countries and clinical origins by a new multilocus sequence-typing (MLST) schema.(More)
PURPOSE Hip subluxation is common in children with cerebral palsy (CP). Surgery is indicated in case of pain or progressive increase of Reimers index on radiographs. Peri-iliac osteotomy combined with femoral osteotomy is one of the numerous operative techniques available, but results at skeletal maturity remain unclear. The purpose of this radiological(More)
BACKGROUND In previous studies, many indicator factors have been proposed to select patients who need an MRI screening of the spinal canal. In current study, the clinical and radiologic factors including coronal parameters of the curve were evaluated to find out which indicator is more important. METHODS A prospective study included 143 consecutive(More)
Study Design Systematic review. Objectives To determine the incidence of catastrophic cervical spine injuries (CCSIs) among elite athletes participating in contact team sports and whether the incidence varies depending on the use of protective gear or by player position. Methods Electronic databases and reference lists of key articles published from January(More)
