STUDY DESIGN: Retrospective analysis of prospectively collected data from the 2001 to 2010 Nationwide Inpatient Sample database. OBJECTIVE: To assess complication rates in adolescent spinal deformity by surgeon operative volume for procedures with a range of complexity. SUMMARY OF BACKGROUND DATA: Surgeons performing higher volumes of lumbar spinal fusion have been associated with improved surgical outcomes, according to studies using the Nationwide Inpatient Sample...

STUDY DESIGN: Prospective consecutive clinical study to assess the decompressive benefit and outcome of oblique lateral interbody fusion for lumbar degenerative diseases. OBJECTIVE: To evaluate radiologically the effect of interbody distraction upon neural patency via an anterolateral retroperitoneal approach for the treatment of lumbar degenerative diseases. SUMMARY OF BACKGROUND DATA: Traditional treatment for symptomatic lumbar stenosis uses direct posterior decompression with or without fusion...

STUDY DESIGN: Single-center retrospective study. OBJECTIVE: To reveal the characteristic changes in central motor conduction time (CMCT) produced by transcranial magnetic stimulation among the responsible levels of cervical compressive myelopathy (CCM). SUMMARY OF BACKGROUND DATA: CMCT is a useful and noninvasive measure for evaluating the central motor pathway. However, a systematic correlation between CMCT findings and the responsible level of CCM has so far not been addressed in a large patient cohort...

OBJECTIVE: To define reference parameters for analyzing sagittal balance of the cervical spine in asymptomatic volunteers. METHODS: Prospective study after Bioethics Committee approval. Imaging performed using a low-dose radiographic system (EOS Imaging, Paris, France). The absence of pain was assessed using the Oswestry Questionnaire and VAS. 106 subjects were included of whom 55.66 % were men. The parameters measured were: pelvic incidence, pelvic tilt, sacral slope, thoracic and lumbar curvature, C7 plumb line position and the spino-sacral angle...

PURPOSE: The aim of this study was to investigate how the severity of operative invasion to the posterior muscular-ligament complex impacts postoperative cervical sagittal balance. MATERIALS AND METHODS: Ninety cases of open-door expansive laminoplasty due to cervical spondylotic myelopathy were reviewed. Fifty-three patients underwent laminoplasty with unilateral preservation of the muscular-ligament complex (unilateral elevation group). Thirty-seven patients underwent traditional open-door laminoplasty (bilateral elevation group)...
