The aim of this study is to identify risk factors associated with postoperative DJF in long constructs for ASD. ⋯ Recently, DJF has received recognition as its own entity due to a notable postoperative incidence. Few studies to date have evaluated risk factors for DJF. The results of our study highlight that pedicle subtraction osteotomy, poor correction of lumbar lordosis, and sagittal vertical axis are significantly associated with postoperative occurrence of DJF.

Transcranial electrical stimulation motor-evoked potentials (TES-MEPs) are an intraoperative neurophysiologic monitoring method that reduces adverse outcomes in various spine surgeries. Although spine surgeons rarely use TES-MEPs for simple lumbar decompression surgery, we herein firstly report the efficacy of TES-MEPs for lumbar spinal canal stenosis with asymptomatic coexisting cervical canal stenosis. ⋯ While TES-MEPs can be used to prevent neurological deficits in lumbar spine surgery, it can also be used to indirectly monitor other spinal lesions. Based on our experience, we recommend using TES-MEPs even in lumbar spine surgery.

Observational Study
Pedicle screw placement safety with the aid of patient-specific guides in a case series of patients with thoracic scoliosis.
Pedicle screw (PS) placement in thoracic scoliotic deformities can be challenging due to altered vertebral anatomy; malposition can result in severe functional disability or inferior construct stability. Three-dimensional (3D) printed patient-specific guides (PSGs) have been recently used to supplement other PS placement techniques. We conducted a single-center, retrospective observational study to assess the accuracy of PS placement using PSGs in a consecutive case series of pediatric and adult patients with thoracic scoliosis. ⋯ The accuracy of PS placement using patient-specific 3D templates in our case series exceeds the accuracies of established thoracic PS placement techniques.

"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.
