Abstract

fetched live from OpenAlex

Five failed retrieved modular Ti-6A1-4V hip stems were examined to determine causes of failure.Investigation included microscopic and macroscopic analysis, finite element analysis, and mechanical testing of the modular hip implant.Method of failure was found to be fatigue, with crack initiation occurring on the lateral side of the modular junction.Bony ingrowth across the modular junction and on the proximal body was not present on both medial and lateral sides.Finite element analysis confirmed that the highest point of stress was where the crack was initiating, its magnitude, and that by case.This implies that examining patient radiographs are not exact and will only suggest certain findings, which must be confirmed or refuted by visual inspection of the Medial Bone Insrowth at BodvLateral Bone Insrowth at Bodv Distal Bone

Full frame distilled prediction

Teacher imitation

Not 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.
