Abstract
PURPOSE: The purpose of this study is to describe the scintigraphic pattern of de Quervain tenosynovitis, a common inflammatory condition of the thumb tendon sheaths related to repetitive use. MATERIALS AND METHODS: The author conducted a retrospective audit of consecutive cases with independent clinical validation of the final diagnosis. RESULTS: There were 7 cases of clinically confirmed de Quervain tenosynovitis. The typical scintigraphic finding was a focal area of superficial linear hyperemia and skeletal uptake along the radial aspect of the distal radius corresponding to the anatomic location of the abductor pollicis longus and extensor pollicis brevis. All cases showed an abnormality on at least one phase of the bone scan. CONCLUSIONS: Bone scanning appears to be of value in the differential diagnosis of dorsolateral wrist pain when clinical findings are nondiagnostic. The scintigraphic appearance of de Quervain tenosynovitis can help to confirm the diagnosis while excluding other causes of wrist pain. Determining the sensitivity and specificity of this pattern will require further research.

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.
