Abstract

fetched live from OpenAlex

CASE: The patient is a 62-year-old man with early tibial baseplate failure involving fracture and subsidence of the posteromedial metal implant, only 3 years after primary total knee replacement. Although this mode of failure is frequently observed secondary to polyethylene wear and osteolysis, this case was likely because of suboptimal tibial baseplate size and positioning with lack of cortical support that underwent accelerated fatigue, given the high activity level of the patient. CONCLUSION: This case demonstrates rare sequelae of inadequate tibial coverage and cortical structural support of the baseplate. Tibial coverage is influenced by implant sizing, implant positioning, and variations in patient anthropometrics.

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.

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.
