Patients with residual adolescent idiopathic scoliosis (AIS) and thoracolumbar/lumbar curves may present with progression after cessation of growth, with lateral translation as a major risk factor. Nonetheless, radiographic predictors and underlying mechanisms remain indefinite. This study aimed to determine these radiographic predictors and structural mechanisms in patients with residual AIS. ⋯ Facet joint instability, L4 tilt ≥20.5°, and L3 cranial vertebral bridging are predictive radiographic factors for L3 lateral translation in patients with residual AIS. Thus, patients exhibiting these characteristics require consistent follow-up or early surgical intervention before lateral translation occurs.

Acute traumatic spinal cord injury (SCI) results in a lifelong condition without any standardized biomarker or corresponding interventions. The objective of this study was to correlate changes in fluid biomarkers with the severity of SCI. ⋯ A negative correlation was observed between biomarkers and functional outcome scores with statistical significance for the 100 kdyn injury. As such, this study demonstrates the potential usefulness of these biomarkers in SCI, especially with regards to impact severity. Futures studies may be conducted at various impact forces to establish a biomarker gradient based on severity of injury.

To develop and validate a nomogram predicting the postoperative adding-on phenomenon in Lenke 1/2 adolescent idiopathic scoliosis patients, providing a quantitative tool for therapeutic benefit assessment and personalized risk prediction. ⋯ The model proved useful for predicting the occurrence of adding-on in Lenke 1/2 adolescent idiopathic scoliosis patients after surgery.

Venous thromboembolism (VTE) is a serious postoperative adverse event after spine surgery. In patients with pain refractory to typical multimodal analgesia regimens after spine surgery, whom are often chronic opioid users, perioperative ketamine is an alternative analgesic that has grown in popularity. The aim of this study is to assess the risk of VTE in chronic opioid users undergoing spine surgery. ⋯ Our study found no association between chronic opioid use and VTE occurrence; however, we identified a significant association between ketamine infusion and VTE after spine surgery. Further studies should be conducted to identify the risks associated with ketamine and other newly implemented alternative analgesics.
