A prospective multicenter randomized study comparing the SpineJack system and nonsurgical management with a brace in acute traumatic vertebral fractures: the SPICO study.

Objective: The objective of this study was to evaluate the efffectiveness of a titanium vertebral augmentation device (SpineJack system) in terms of back pain, radiological outcomes, and economic burden compared with nonsurgical management (NSM) (bracing) for the treatment of vertebral compression fractures. Complications were also evaluated for both treatment methods.

Methods: A prospective multicenter randomized study was performed at 9 French sites.

Surgical management of isthmic spondylolisthesis: A comparative study of postoperative outcomes between ALIF and TLIF.

Introduction: Circumferential fusion by the anterior (ALIF) or transforaminal (TLIF) approach combined with posterior instrumentation is currently used for the surgical treatment of low-grade isthmic spondylolisthesis. But few studies have compared the clinical and radiological outcomes of various interbody fusion techniques. The objective of this study was to compare the clinical and radiological results at 2 years postoperative of two fusion techniques-TLIF versus ALIF plus posterior instrumentation-for low-grade isthmic spondylolisthesis in adults.

Fusion and clinical outcomes of lumbar interbody fusion for low-grade isthmic spondylolisthesis.

Introduction: Low-grade isthmic spondylolisthesis (ISPL) is generally treated by circumferential fusion with interbody graft, although there is no consensus on technique.

Hypothesis: The various interbody fusion strategies provide satisfactory fusion rates and clinical results.

Methods: A multicenter retrospective study analyzed lumbar interbody fusion for low-grade ISPL performed between March 2016 and March 2019.

Dynamic global sagittal alignment in patients with lumbar spinal stenosis: Analysis of the effects of decompression surgery on gait adaptations.

Background: Lumbar spinal stenosis (LSS) leads patients to adapt their posture and walking parameters. Pelvic retroversion might be a compensation mechanism of pain. Pelvic and lower limbs compensations during gait are still not precisely understood, as well as the effect of a surgical decompression on them.

Under-contouring of rods: a potential risk factor for proximal junctional kyphosis after posterior correction of Scheuermann kyphosis.

Objective: Scheuermann kyphosis (SK) could require surgical treatment in certain situations. A posterior reduction is the most widespread treatment so far, although the development of proximal junctional kyphosis (PJK) is one of the possible complications of this procedure. The contour of the proximal part of the rod could influence the occurrence of PJK in SK patients.

An analysis of the interactions between the spine, pelvis, and lower limbs in asymptomatic adults with limited pelvic compensation.

Background: The interactions between the spine, pelvis, and lower limbs are dynamic based on the "cone of economy" concept; thus, different global radiographic parameters could be regarded as reflections of different centers of gravity. We conducted this retrospective study to evaluate the offsets of different centers of gravity in asymptomatic populations and to investigate how the global sagittal alignment is supported.

Methods: The following parameters were measured: cervical lordosis, thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), the ratio between PT and PI (PT/PI), sacral slope, PI minus LL (PI-LL), the sagittal vertical axis (SVA), cranial SVA to ankle center (Cr-A), CrSVA to the femoral head center (Cr-FH), C2SVA to the femoral head center (C2-FH), pelvic translation (P.

Patients with Coronavirus 2019 (COVID-19) and Surgery: Guidelines and Checklist Proposal.

The management of patients with novel coronavirus 2019 (COVID-19) represents a new challenge for medical and surgical teams. Each operating room in the world should be prepared thoughtfully, and the development of a protocol and patient route seems mandatory. An adequate degree of protection must be used.

Walking Speed as an Alternative Measure of Functional Status in Patients with Lumbar Spinal Stenosis.

Objective: The main objective was to compare estimated walking perimeter (WP) and actual WP during a free walking test (6-minute walk test [6MWT]) in patients with lumbar spinal stenosis (LSS). The second objective was to describe the correlation between measured gait parameters and functional parameters.

Methods: This was a single-center prospective study including 38 patients with symptomatic LSS (23 men, 15 women; mean age, 69.

Cervical Cord Compression by Exostosis.

A 51-year-old woman presented to physical therapy with complaints of weakness in her left arm, progressive numbness in both hands, and mild progressive neck pain radiating into the left upper arm. She reported that her condition had started after playing in an amateur tennis tournament 4 weeks prior and progressed to inability to play tennis. Following examination by the physical therapist, the patient was referred to her physician, who ordered magnetic resonance imaging of the spine, which showed a bony exostosis at C1-2 with myelopathy.

Cervical Hyperextension Deformity After Sagittal Balance Correction in Patient with Congenital Limb-Girdle Myopathy: Surgical Technique and Review of Literature.

Background: There is no gold standard surgical treatment for cervical hyperextension deformity, especially in case of muscular dystrophy. Special considerations and caution should be taken as they carry a high risk of early mortality and spinal cord injury. Only a few case reports are available in the literature.

Rare Complication of Percutaneous Technique: Intradural Cement Leakage and Its Surgical Treatment.

Popularity of percutaneous vertebroplasty and vertebral augmentation to treat vertebral compression fractures is increasing. Cement leakages are relatively common, but intradural cement leakage is rare. Few cases of intradural cement leakage have been reported in the literature, and emergency surgery has been reported to be <1%.

Mid-Term Clinical and Radiological Outcomes After Kyphoplasty in the Treatment of Thoracolumbar Traumatic Vertebral Compression Fractures.

Background: The management of thoracolumbar posttraumatic compression fractures varies widely among centers, and there is no real consensus as to the optimum approach. The objective of our retrospective study was to detect the progression of vertebral kyphosis in nonosteoporotic patients treated by balloon kyphoplasty (KPB) who presented with recent compression fractures of the thoracolumbar region.

Methods: In this retrospective study, we investigated the evolution of vertebral and regional kyphosis in 77 patients treated by KPB for compression vertebral fractures (Magerl A) between 2007 and 2011.

Improvement in Sagittal Balance After Decompression Surgery without Fusion in Patients with Degenerative Lumbar Stenosis: Clinical and Radiographic Results at 1 Year.

Objective: To evaluate modifications in static spinal status after posterior decompression surgery without fusion in patients with symptomatic central canal stenosis.

Methods: From November 2014 to May 2016, 72 patients who underwent isolated decompression for lumbar spinal stenosis were enrolled prospectively in this single-center study. All of the patients had lateral full-body x-ray scans with the EOS system (EOS Imaging, Paris, France) before surgery and after 12 months of follow-up.

Temporal trends in early case-fatality rates in patients with intracerebral hemorrhage.

Objective: To assess whether temporal trends in very early (within 48 hours) case-fatality rates may differ from those occurring between 48 hours and 30 days in patients with spontaneous intracerebral hemorrhage (ICH).

Methods: All cases of ICH that occurred in Dijon, France (151,000 inhabitants), were prospectively collected between 1985 and 2011, using a population-based registry. Time trends in 30-day case fatality were analyzed in 3 periods: 1985-1993, 1994-2002, and 2003-2011.

Assessment of the Radiation Exposure of Surgeons and Patients During a Lumbar Microdiskectomy and a Cervical Microdiskectomy: A French Prospective Multicenter Study.

Objective: Cervical and lumbar disk herniations are the most frequently carried out procedures in spinal surgery. Often, a few snapshots during the procedure are necessary to validate the level or to position the implant. The objective of this study is to quantitatively estimate the radiation received by a spine surgeon and patient during a low-dose radiation procedure.

Surgical-site infection in spinal injury: incidence and risk factors in a prospective cohort of 518 patients.

Purpose: To investigate the incidence of surgical-site infection (SSI) and determinate the risk factors of SSI in the context of spinal injury.

Methods: From February 1, 2011 to July 31, 2011, for a multicentre cohort of patients with acute spinal injury, we prospectively censored those with SSI for at least 12 months. We recorded epidemiologic characteristics and details of surgical procedure and postoperative care for each patient.
