The static sagittal balance of the normal spine is a physiological alignment of the spine in the most efficient manner by the muscular forces. During gait, this balance is constantly thwarted by single-foot support. This analysis involves the study of parameters which are now well defined. ⋯ Taking these parameters into account also enables us to understand the complications involved in this type of surgery: transitional syndromes or junctional syndromes. Integration of these parameters into the study of gait is an area still under investigation. These slides can be retrieved under Electronic Supplementary Material .

Major complications are a concern following ASD surgery. Even when properly managed and resolved, they may still have a relevant impact on HRQL. We aimed to investigate the impact of resolved early major complications on 2-year outcome after ASD surgery. ⋯ The results indicate that patients experiencing major complications after ASD surgery have significantly less functional improvement (SRS-22 function, ODI, SF-36 PCS) than their complication-free counterparts, even when complications were considered resolved, and the outcome was measured after an 18-month complication-free period.

Lumbar spine fusion with anterior (ALIF) or lateral (LLIF) approach is a moderately painful procedure associated with significant length of hospital stay (LoS) and opioid requirements. We developed an opioid-sparing analgesic pathway of care for ALIF and LLIF, featuring transversus abdominis plane (TAP) block. In this study, we assessed the feasibility of performing the TAP block as an analgesic adjunct for ALIF or LLIF. ⋯ Applying TAP block to spine surgery is a novel pain management strategy. This study demonstrates high patient acceptance and the general safety of the technique. Although lacking a control arm, these results also provide preliminary data supporting efficacy.

To determine the relationship between the bone formation-related functions of GPR126 and the structural asymmetry of spine in adolescent idiopathic scoliosis (AIS). ⋯ Our findings indicated that GPR126-NTFs play a role in skeletal development, and the inclusion/exclusion of exon6 may regulate the bone formation-related functions of GPR126. The convex/concave asymmetric expression of GPR126-exon6in may be an important factor in abnormal bone formation of AIS. These slides can be retrieved under Electronic Supplementary Material.

Immediate postoperative coronal imbalance in Lenke 5 and Lenke 6 adolescent idiopathic scoliosis: Is it predictable?
Immediate postoperative coronal imbalance (IPCIB) is a common reason for worse postoperative appearance in adolescent idiopathic scoliosis (AIS) patients and rarely improves on its own at follow-up, thereby greatly influencing the patients' health-related quality of life. However, no studies have been performed to detect the primary risk factors for IPCIB and it remains unclear whether the condition can be predicted preoperatively. The purpose of this study is to detect the primary risk factors for IPCIB in Lenke 5 and Lenke 6 AIS patients and to explore whether IPCIB can be predicted preoperatively. ⋯ The preoperative bending L5 tilt, postoperative translation of the thoracic apex, and the postoperative lumbar Cobb angle were the primary risk factors for IPCIB in Lenke 5 and Lenke 6 AIS patients. The IPCIB index can be used to predict the occurrence of IPCIB with high accuracy. Our results indicate that the thoracic curve should be adequately corrected during surgery; however, moderate correction of the lumbar curve is recommended.
