A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Strut allografts are not recommended after a femoral shaft exposure, because they may endanger the femoral blood supply. Up till now, we have seen no clinical reports on this problem. We treated 13 consecutive patients with very large anteromedial and anterolateral femoral strut allografts to restabilize periprosthetic fractures which had become loose after a previous attempt at surgical fixation (Vancouver type B fractures with severe bone loss). In 8 cases, the stem was revised in conjunction with the use of strut allografts and in 5 cases, strut allografts alone were used. All refractures and nonunions healed without further treatment. At a mean follow-up of 3 (1.2-7) years, the mean Harris Hip Score was 78 (65-92). All strut grafts showed ingrowth with augmentation of periprosthetic bone on the radiographs. There were 3 complications, 1 nonprogressive subsidence of a revision stem (fibrous stable), 1 deep hematoma and 1 partial lesion of the sciatic nerve. In this series, strut grafts gave reliable healing with augmentation of the host bone stock despite previous femoral exposure, severe bone loss, adverse type of fracture, and persistent instability at the index operation.

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.
