A systematic search was conducted to study the efficiency of preventive educational interventions mainly focused on a biomechanical/biomedical model. ⋯ The results of the RCTs included in this review suggest that educational interventions mainly focused on a biomechanical/biomedical model are not effective in preventing LBP. However, taking into account the methodological quality level of the RCTs as well as the very short and heterogeneous interventions often proposed, additional high-quality studies with a longer education period are needed to conclude that such interventions are inefficient.

Multicenter Study
Risk factors for major peri-operative complications in adult spinal deformity surgery: a multi-center review of 953 consecutive patients.
Major peri-operative complications for adult spinal deformity (ASD) surgery remain common. However, risk factors have not been clearly defined. Our objective was to identify patient and surgical parameters that correlate with the development of major peri-operative complications with ASD surgery. ⋯ The major peri-operative complication rate was 8.4 % for 953 surgically treated ASD patients. Significantly higher rates of complications were associated with staged and combined anterior-posterior surgeries. None of the patient factors assessed were significantly associated with the occurrence of major peri-operative complications. Improved understanding of risk profiles and procedure-related parameters may be useful for patient counseling and efforts to reduce complication rates.

Comparative Study
Validation of a novel spinal posture monitor: comparison with digital videofluoroscopy.
A novel, minimally invasive posture monitor which can monitor lumbar postures outside the laboratory has demonstrated excellent reliability, as well as concurrent validity compared to a surface marker-based motion analysis system. However, it is unclear if this device reflects underlying vertebral motion. ⋯ The BodyGuard™ appears to be a valid method for analysing vertebral motion in the sagittal plane and is a promising tool for long-term monitoring of spinal postures in laboratory and clinical settings in people with low back pain.

Randomized Controlled Trial
Development of a per-operative procedure for concentrated bone marrow adjunction in postero-lateral lumbar fusion: radiological, biological and clinical assessment.
Addition of bone marrow to the bone graft in the postero-lateral lumbar arthrodesis is a widely used technique. Bone marrow brings stem cells and growth factors contained in the platelets, favorable for bone growth. Adjunction of concentrated bone marrow should create better conditions and may increase bone growth. ⋯ Despite the concentration obtained, there was no increase of bone growth by adding concentrated bone marrow. However, the number of stem cells in bone marrow was low and maybe a stronger concentration is needed to obtain a difference. The 3D reconstruction of the graft and the analysis of the graft's volume using a novel software was efficient according to the similarity of the graft's volume post-operatively in all patients.

To compare mid-term clinical outcomes of two revision strategies for patients with failed SB Charité III total disc replacements (TDRs). ⋯ Both procedures showed improvement clinically. There were no significant additional benefits of removing the TDR as compared to fusion alone at mid-term follow-up. The clinical decision to remove the TDR should be carefully weighed up against potential risks and complications of this procedure.
