Traumatic hyperextension-distraction injuries of the thoracolumbar spine: a technical note on surgical positioning.

Eur Spine J 2019 Feb 15. Epub 2019 Feb 15.

Department of Orthopedics, University of Alabama at Birmingham, 510 20th St. S, Birmingham, AL, 35233, USA.

Purpose: Hyperextension-distraction type injury of the thoracolumbar spine is an unstable fracture pattern that generally necessitates surgical stabilization by posterior instrumentation. Care must be taken when positioning these patients from supine to prone due to the unstable nature of their injury. The study objectives were (1) to describe a novel modification of the Jackson table turn technique, which may be safer and more effective than the conventional log-roll method and traditional Jackson table technique for positioning patients with hyperextension-distraction injuries of the thoracolumbar spine from supine to prone in the operating room and (2) to present two cases in which this technique was successfully performed.

Inter-spinous process distance: a novel parameter predicting segmental lordosis during posterior cervical spine deformity surgery.

Eur Spine J 2019 Feb 15. Epub 2019 Feb 15.

Department of Orthopaedic Surgery, Columbia University Medical Center, The Spine Hospital at New York Presbyterian, New York, USA.

Purpose: To investigate the normative value of distance between the spinous processes (inter-spinous process distance, ISPD), correlations between patients' demographics and ISPD, and determine cutoff ISPD values that result in segmental lordosis in posterior cervical-thoracic arthrodesis with instrumentation.

Methods: We reviewed patients with visible lower cervical and cervicothoracic spinous processes (C5-T2) on dynamic X-rays. Radiographic measurements included segmental Cobb angles (S-Cobb) and ISPD, defined as the distance between midpoints of the spinous processes. Read More

Development of a novel model for predicting survival of patients with spine metastasis from colorectal cancer.

Eur Spine J 2019 Jan 18. Epub 2019 Jan 18.

Department of Orthopedic Oncology, Changzheng Hospital, Second Military Medical University, 415 Fengyang Road, Shanghai, 200003, China.

Objective: To develop a novel nomogram for predicting survival of patients with spine metastasis from colorectal cancer (SMCRC) based on the clinical characteristics and prognostic factors.

Methods: Included in this study were 93 SMCRC patients who received treatments in our institute between 2006 and 2017, whose clinical data were analyzed retrospectively by univariate and multivariate analysis to identify independent variables that could predict prognosis. A nomogram for survival prediction was established on the basis of preoperative independent factors, and then subjected to bootstrap re-samples for internal validation. Read More

Sonication of removed implants improves microbiological diagnosis of postoperative spinal infections.

Eur Spine J 2019 Jan 17. Epub 2019 Jan 17.

Charité - Universitätsmedizin Berlin, Chariteplatz 1, 10117, Berlin, Germany.

Purpose: In total joint replacement, culturing of the sonication fluid of removed implants has proven to be more sensitive than conventional periprosthetic tissue culture for the microbiological diagnosis of prosthetic joint infection. However, its role in postoperative spinal implant infection (PSII) is not well investigated. Therefore, the aim of this study was to determine the validity of sonication in detecting infection following instrumented spine surgery. Read More

Identification of abnormalities in the lumbar nerve tract using diffusion-weighted magnetic resonance neurography.

Eur Spine J 2019 Jan 17. Epub 2019 Jan 17.

Department of Orthopedics, Institute of Biomedical Sciences, Tokushima University Graduate School, 3-18-15 Kuramoto-cho, Tokushima, 770-8503, Japan.

Introduction: Abnormalities of the lumbar nerve tract caused by congenital variations or high nerve root take-off angles are difficult to visualize. Diffusion-weighted magnetic resonance neurography (DW-MRN) has recently been introduced for imaging of the lumbosacral region. The aims of this study were to identify lumbar nerve tract abnormalities caused by congenital variation or a high nerve root take-off angle using DW-MRN and to assess the diagnostic value of this imaging modality.

Department of Orthopaedic Surgery, Research School CAPHRI, Maastricht University Medical Center, P. Debyelaan 25, 6229 HX, Maastricht, The Netherlands.

Purpose: The aim of this study was to develop and internally validate a multivariable model for accurate prediction of surgical site infection (SSI) after instrumented spine surgery using a large cohort of a Western European academic center.

Method: Data of potential predictor variables were collected in 898 adult patients who underwent instrumented posterior fusion of the thoracolumbar spine. We used logistic regression analysis to develop the prediction model for SSI. Read More

Is rasterstereography a valid noninvasive method for the screening of juvenile and adolescent idiopathic scoliosis?

Eur Spine J 2019 Jan 7. Epub 2019 Jan 7.

III Spine Surgery - Scoliosis Department, IRCCS Istituto Ortopedico Galeazzi, Milan, Italy.

Purpose: Aim of the study was to verify the accuracy of rasterstereography (RST), as radiation-free alternative to plain radiography (RAD) in the monitoring of spine deformity and scoliosis progression in juvenile and adolescent subjects with idiopathic scoliosis.

Methods: 192 subjects underwent RST (by Formetric 4D device) and low-dose RAD (EOS Imaging, France) in the same session. A sub-group of 30 subjects, selected for conservative treatment with corrective bracing, was assessed at 6-months follow-up. Read More

Differential patient responses to spinal manipulative therapy and their relation to spinal degeneration and post-treatment changes in disc diffusion.

Eur Spine J 2019 Jan 2. Epub 2019 Jan 2.

Department of Physical Therapy, University of Alberta, Edmonton, AB, Canada.

Purpose: Our prior study revealed that people with non-specific low back pain (LBP) who self-reported a > 30% improvement in disability after SMT demonstrated significant post-treatment improvements in spinal stiffness, dynamic muscle thickness and disc diffusion, while those not having self-reported improvement did not have these objective changes. The mechanism underlying this differential post-SMT response remains unknown. This exploratory secondary analysis aimed to determine whether persons with non-specific LBP who respond to spinal SMT have unique lumbar magnetic resonance imaging (MRI) findings compared to SMT non-responders.
