Proximal Flexor Digitorum Superficialis Calcification Causing Ulnar Neuralgia at the Elbow Treated with Ultrasound-Guided Lavage
Bibliographic record
Abstract
Distal flexor digitorum superficialis (FDS) calcific tendinopathy has been described in the fingers [1], even though it remains rare compared with other locations of calcific tendinopathy. However, there is no mention in the literature of proximal FDS calcific tendinopathy. Ultrasound (US) examination of a 52-year-old woman with progressive atraumatic right ulnar neuralgia revealed ulnar nerve mild focal swelling at the cubital tunnel and a 9×13×6-mm calcification within the tendinous portion of the proximal humeroulnal head of the FDS (Figure 1; Supplementary Video 1). An anteroposterior x-ray of the right elbow before the procedure was also done (Figure 2). A dynamic US study showed impingement of the ulnar nerve over the calcification with elbow flexion (Figure 1; Supplementary Video 1). ... An US-guided percutaneous lavage of the calcification was performed (Figure 3; Supplementary Video 1), immediately followed by a 40-mg methylprednisolone injection within the proximal humeroulnar head of the FDS tendon. A control x-ray four weeks later was compatible with the resorption of calcifications.

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.
