Polyostotic Fibrous Dysplasia of the Thoracic Spine
Bibliographic record
Abstract
STUDY DESIGN: A case report of polyostotic fibrous dysplasia including thoracic spine, sacral vertebrae, and temporal bone, with the symptom of back pain. OBJECTIVE: To treat the lesions with percutaneous kyphoplasty. SUMMARY OF BACKGROUND DATA: Polyostotic fibrous dysplasia involving either spine or temporal bone is rarely seen. Few reports of this disorder appear in the literature. This is the first case including thoracic spine, sacrum, and temporal bone together presented to date. METHODS: The patient was a 56-year-old woman with polyostotic fibrous dysplasia involving the thoracic spine of the eighth, ninth, and 10th vertebral body; adjacent rib; the right temporal bone and the sacrum. Percutaneous kyphoplasty in ninth and 10th vertebral body was carried out to achieve substantial pain relief and rapid stabilization of the spine with minimal invasion. RESULTS: The patient experienced complete pain relief and had no clinical complications associated with the cement leakage. The patient tolerated the procedure well. There were no clinical complications and substantial pain relief was noted within hours of the procedure. She has no pain or disability at 1-year follow-up. CONCLUSION: Percutaneous kyphoplasty was a good therapeutic option for the reported patient.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
