Unerkannte Dissoziation des bipolaren Avantage®-Hüftprothesensystems (Biomet®) nach geschlossener Reposition einer Hüftluxation: eine seltene Komplikation
Bibliographic record
Abstract
Eine 84-jährige Patientin wurde mit einer periprothetischen Femurfraktur bei einliegender Hüftprothese (Avantage-Pfannensystem, Biomet®) in unserer Notfallambulanz vorstellig. Die konventionellen Röntgenaufnahmen von Becken und linkem Hüftgelenk zeigten neben der periprothetischen Fraktur Typ Vancouver B2 eine Dezentrierung des Prothesenschafts. Die weiterführende CT-Diagnostik zeigte eine Dissoziation des Polyethyleninlays vom Prothesenkopf, die sich im Rahmen einer bereits 3 Jahre zurückliegenden geschlossenen Reposition nach erfolgter postoperativer Luxation ereignete. Dieser Fall zeigt die Relevanz einer genauen Analyse von Röntgenkontrollaufnahmen post repositionem bez. der exakten Artikulation der Prothesenelemente.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
