Multicenter Study
Comparison of four correction techniques for posterior spinal fusion in adolescent idiopathic scoliosis.
When performing posterior spinal fusion for adolescent idiopathic scoliosis (AIS), it is of major importance to address both coronal and sagittal deformities. Although several techniques have been described, few data exist comparing them. Our objective was to compare four techniques (in situ bending (ISB), rod derotation (RD), cantilever (C) and posteromedial translation (PMT)) for the correction of spinal deformity in AIS including thoracic deformity. ⋯ The four techniques had the same ability to correct spinal deformity in the coronal plane. Three factors were identified to improve correction rate: implant density, convex compression and use of derotation connectors. On the other hand, PMT was more effective in restoring TK, particularly in hypokyphotic patients.

There is a paucity of literature identifying factors that influence the back and neck pain (BNP)-workplace absenteeism relationship. Therefore, this study aimed to investigate the association between BNP and workplace absenteeism and potential mediating variables in a large sample of the US population. ⋯ Workplace interventions focusing on the management of BNP and overcoming difficulties in walking, standing, and sitting, potentially utilizing exercise, therapy, and ergonomic interventions, may prevent absenteeism.

While the effects of VBT on coronal parameters have been investigated in various studies, this has not yet been the case for sagittal parameters. This is of particular relevance considering that VBT does not allow direct correction of the sagittal profile. Thus, we investigated the effects of VBT on sagittal parameters in patients with adolescent idiopathic scoliosis. ⋯ VBT positively influences sagittal parameters and does not have a kyphotic effect on LL.

There is a paucity of studies on new vertebral body tethering (VBT) surgical constructs especially regarding their potentially motion-preserving ability. This study analyses their effects on the ROM of the spine. ⋯ The investigated VBT techniques preserved global ROM of the spine in flexion-extension and axial rotation while reduced the ROM in lateral bending.
