This study examines patients with metastatic spinal disease undergoing non-total en bloc spondylectomy, focusing on revision surgery reasons and its effectiveness in treating spinal instability, neurological issues, and pain. ⋯ Long-segment fixation with radiotherapy may reduce revision surgery need and extend the time between surgeries. Hybrid or separation surgeries lower the likelihood of revision. Revision surgery can relieve pain and improve neurological function. Patients in the revision group have longer survival times.

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.
