Abstract
This chapter presents a clinical scenario of a 13-year-old girl who has activity-related pain below the medial malleolus, and on occasion in the medial arch of foot and in the sinus tarsi. X-rays are suggestive of a tarsal coalition with flatfoot deformity including 16° of hindfoot valgus. There are no degenerative changes of the posterior facet. Concomitant flatfoot deformity is commonly seen with talocalcaneal (TC) coalitions and can cause pain and disability. TC coalitions typically involve the middle facet, but can occur at any location in the subtalar joint. CN is the most common type of tarsal coalition, representing 54% of all coalitions. Although deformity is more common in TC coalitions, CN coalitions can also present with flatfoot deformity causing pain and disability. Unlike TC coalitions, CN coalitions do not involve a joint. They act as an extra-articular tether, limiting movement through otherwise healthy cartilage.
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.

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.
