Abstract

fetched live from OpenAlex

The influence of surgery on the relationship between the lumbar spine and the pelvis in adolescent idiopathic scoliosis (AIS) remains mostly unknown. The sagittal spinopelvic balance of 40 patients with AIS undergoing posterior spinal instrumentation and fusion was studied. After surgery, the total lumbar lordosis (LL) and the LL below fusion remained correlated to the sagittal pelvic geometry. LL within fusion, which is set by the instrumentation, was also related to the LL below fusion. This preliminary study shows that pelvic morphology probably has an important impact on the postoperative sagittal lumbar alignment. Evaluation of the sagittal pelvic geometry could therefore be useful in the preoperative planning of surgery for AIS. Further studies with more patients are still needed in order to confirm this hypothesis and to evaluate if the distal fusion level influences the spino-pelvic balance.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
