This study aimed to investigate how preoperative motion analysis results affect the postoperative clinical outcomes of patients undergoing surgery for adult spinal deformity (ASD). ⋯ The study highlights that a high preoperative Ant-PT angle in motion analyses is associated with poor clinical outcomes after surgery for ASD. Therefore, it is necessary to observe and consider the dynamic gait pattern related to the compensatory mechanism for sagittal imbalance in the decision-making process for ASD surgery.

"After-hours" non-elective spine surgery is associated with increased morbidity. Decision-making may be enhanced by collaborative input from experienced local colleagues. At our center, we implemented routine use of a cross-platform messaging system (CPMS; WhatsApp Inc., Mountain View, California) to facilitate quality care discussions and collaborative surgical decision-making between spine surgeons prior to booking cases with the operating room. Our aim is to determine whether encrypted text messaging for shared decision-making between spine surgeons affects the number or type of after-hours spine procedures. ⋯ Prospective (i.e., prior to booking surgery) quality care discussion for joint decision-making among spine surgeons using CPMS may reduce both the number and complexity of after-hours procedures.

The short rod technique (SRT) is a novel method for lumbar pedicle screw placement to reduce surgical trauma and avoid damage to the facet joint and articular surface. The core concept is to change the entry point and angle of the screw on the vertebrae at both ends in the sagittal plane to shorten the length of the longitudinal rods. The purpose of this study is to determine the sagittal screw angle (SSA) and its safe Maximum (MAX) value on each lumbar vertebra for the SRT and to observe the shortening effect on the longitudinal rods. ⋯ The application of the SRT to lumbar pedicles is a safe screw placement method that can significantly shorten the length of the used longitudinal rods.

To explore the characteristics of spontaneous facet joint fusion (SFJF) in patients after oblique lateral lumbar interbody fusion combined with lateral single screw-rod fixation (OLIF-LSRF). ⋯ In the OLIF-LSRF procedure, SFJF occurs mostly at 3-6 months postoperatively, especially in elderly patients and at the right facet joint. OLIF-LSRF has the potential for circumferential fusion.
