Abstract
Femoral head osteonecrosis (ON) presents in about 10% of all total hip arthroplasty (THA) patients in united states (1). There have been a variety of traumatic and atraumatic factors identified as risk factors for ON, but the etiology and pathogenesis still remains unclear. Ollivier et al. ’s work is trying to shed a light on the anatomical associations with idiopathic ON. In this study, hip morphology was compared (obtained by CT scan) between patients who had idiopathic femoral head ON and a matched control group of patients to determine whether any observed differences could have possible associations with the disease process. In this study, there was significant differences between the two groups and found ON group to be associated with a decreased femoral neck-shaft angle of 17°), less acetabular coverage (lateral center-edge angle of <32°) and less acetabular version <19° (2).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
