22-year-old woman with acute-on-chronic ankle pain
Bibliographic record
Abstract
A 22-year-old woman with a history of chronic right ankle pain for 8 years presented with pain exacerbation over the right talus over the previous 7 months. There was no recent history of trauma. The pain was aggravated by not wearing orthotics. No alleviating factors were identified. There was no history of instability or clicking. Past treatments included physiotherapy and ibuprofen. Physical examination revealed pes planus with normal gait, normal weight bearing and normal range of motion. No skin changes or pain on palpation was identified. Focused neurovascular examination was normal. The anterior drawer, talar tilt and tibial torsion tests were all normal. Ankle radiographs (figures 1 and 2) were obtained. Figure 1 Anteroposterior radiograph of the right ankle. Figure 2 Lateral radiograph of the right ankle. What is your diagnosis? Talocalcaneal tarsal coalition. ### Anteroposterior radiograph of right ankle No abnormality is appreciable on this anteroposterior radiograph. This image demonstrates a complete C-sign with osseous bridging. There is narrowing of the posterior subtalar facet, a short talar neck and a small dorsal subtalar beak. The magnetic resonance images demonstrate bone marrow oedema across the middle subtalar joint, cortical irregularity and small subchondral cysts, in keeping with fibrous coalition. Tarsal coalition is an abnormal union between two or more tarsal bones. The coalition can be osseous, fibrous or cartilaginous. Tarsal coalition is relatively common on autopsy, with an incidence of up to 1% of the population; although the majority of these are thought to be asymptomatic.1 Most cases of tarsal coalition …

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
