Randomized Controlled Trial
No difference in 9-year outcome in CLBP patients randomized to lumbar fusion versus cognitive intervention and exercises.
To compare the 9-year outcome in patients with chronic low back pain treated by instrumented lumbar fusion versus cognitive intervention and exercises. ⋯ The outcome at 9 years was not different between instrumented lumbar fusion and cognitive intervention and exercises.

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.

Randomized Controlled Trial
Spine surgeon's kinematics during discectomy according to operating table height and the methods to visualize the surgical field.
The ergonomic problems for surgeons during spine surgery are an awkward body posture, repetitive movements, increased muscle activity, an overflexed spine, and a protracted time in a standing posture. The authors analyzed whole spine angles during discectomy. The objective of this study is to assess differences in surgeon whole spines angles according to operating table height and the methods used to visualize surgical field. ⋯ This study suggests that loupe use and a table height midpoint between the umbilicus and sternum are optimal for reducing surgeon musculoskeletal fatigue.

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.

We describe cases presenting with progressive thoracic myelopathy after lumbopelvic fusion attributed to proximal junctional vertebral compression fracture (PJF) followed by spinal calcium pyrophosphate dehydrate (CPPD) crystal deposition. ⋯ The combination of mechanical stress plus PJF and CPPD crystal deposition followed by a foreign body reaction to the deposited crystals caused myelopathy. Patients with radiographic evidence of PJF, especially UIV collapse, after lumbopelvic fusion should be followed carefully for the emergence of myelopathy.
