Abstract
This study reviews the second case in the literature involving the use of frozen osteochondral allograft to reconstruct a femoral head fracture-dislocation. The case involved significant, unreconstructable damage to the weightbearing area of the femoral head in an 18-year-old male. Clinical and diagnostic imaging follow up at 46 months revealed that despite magnetic resonance imaging and radiographic evidence of progressive arthrosis in the hip, including subchondral cystic change in the femoral head and localized cartilage loss in the acetabulum and femoral head, the patient had excellent function with no complications (Harris hip score 100, hip dysfunction and osteoarthritis outcome score 62, musculoskeletal function assesment score 22, SF-36 score 81). The use of osteochondral allograft may serve as a useful tool for the orthopaedic surgeon faced with an unreconstructable femoral head fracture-dislocation in a young patient.

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
