Importance of the preoperative cross-sectional area of the semispinalis cervicis as a risk factor for loss of lordosis after laminoplasty in patients with cervical spondylotic myelopathy
ConclusionPreoperative SCSA of the semispinalis cervicis was a risk factor for LCL after laminoplasty. Spine surgeons should evaluate semispinalis cervicis muscularity at the C6 level when planning laminoplasty for patients with CSM.Graphical abstract These slides can be retrieved under Electronic Supplementary Material.

The Global Spine Care Initiative: public health and prevention interventions for common spine disorders in low- and middle-income communities
ConclusionPrevention principles and health promotion strategies were identified that were incorporated in the GSCI care pathway. Interventions should encourage healthy behaviors of individuals and promote public health interventions that are most likely to optimize physical and psychosocial health targeting the unique characteristics of each community. Prevention interventions that are implemented in medically underserved areas should be based upon best evidence, resource availability, and selected through group decision-making processes by individuals and the community.Graphical abstractThese slides can be retrieved under...

Is vertebral body stenting in combination with CaP cement superior to kyphoplasty?
ConclusionsBoth techniques facilitated good clinical results in combination with absorbable cement augmentation. In particular, the VBS enabled us to benefit from the advantages of the resorbable isothermic CaP cement with an improved radiological outcome in the long term compared to BKP. However, there was a mentionable loss of reduction in the follow-up in both groups compared to previously published data with PMMA cement.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

CT for thoracic and lumbar spine fractures: Can CT findings accurately predict posterior ligament complex injury?
ConclusionWhile no individual CT finding is sufficiently accurate to diagnose or exclude PLC injury, greater the number of positive CT findings (VBT, PLF, ISW, and SPF), the higher the odds of PLC injury. The presence of a single abnormal CT finding may warrant confirmatory MRI for PLC injury, while two or more CT findings may have adequate specificity to avoid need for MRI prior to surgical intervention.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

Predicting medical complications in spine surgery: evaluation of a novel online risk calculator
AbstractPurposeThe preoperative prediction of medical complications is essential to optimize perioperative management. SpineSage ™ is a free of charge online calculator to predict medical complications in spine surgery. The current study utilizes it in patients undergoing spine surgery to assess whether the predicted risks would correlate with the actual complication rate in clinical practice.MethodsA total of 273 consecutive patients who underwent spinal surgery were assessed. The risk of medical complications was predicted for each patient, and all medical complications were recorded within 30  days of surgery...

Comparison of combined anterior –posterior approach versus posterior-only approach in neuromuscular scoliosis: a systematic review and meta-analysis
ConclusionsOur meta-analysis suggested that POA was similar to APA in the correction of scoliosis in coronal and sagittal planes.

Does the META score evaluating osteoporotic and metastatic vertebral fractures have enough agreement to be used by orthopaedic surgeons with different levels of training?
AbstractPurposeDifferentiating osteoporotic vertebral fractures (OVF) from metastatic vertebral fractures (MVF) is difficult. A magnetic resonance imaging (MRI)-based score (META score) aiming to differentiate OVF and MVF was recently published; however, an independent agreement assessment is required before the score is used. We performed such independent agreement evaluation, including raters with different levels of training.MethodsSixty-four patients with confirmed OVF or MVF were evaluated by six raters (three spine surgeons and three orthopaedic residents) using the META score. We used the intra-class correlation coe...

TRPC6 in simulated microgravity of intervertebral disc cells
ConclusionsSimulated microgravity and TRPC channel inhibition both led to reduced proliferation and increased senescence. Furthermore, simulated microgravity reduced TRPC6 expression. IVD cell senescence and mechanotransduction may hence potentially be regulated by TRPC6 expression. This study thus reveals promising targets for future studies.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material. (Source: European Spine Journal)
