Klinisches Outcome und schrittzählerbasierte Aktivität nach minimalinvasivem Hüftgelenksersatz über einen direkt anterioren Zugang
Bibliographic record
Abstract
In einer prospektiven Studie zum minimalinvasiven Hüftgelenksersatz über einen direkt anterioren Zugang wurden präoperativ, 6 Wochen und 3 Monate postoperativ (N=46) der Western Ontario and McMaster University Osteoarthritis Index (WOMAC), die gesundheitsbezogene Lebensqualität (SF-36), der Harris Hip Score (HHS) und die körperliche Aktivität (StepWatch 3ª Activity Monitor) erfasst. Der WOMAC, HHS und die körperlichen Skalen des SF-36 zeigten bereits nach 6 Wochen einen deutlichen Anstieg. Die körperliche Aktivität verringerte sich hingegen von 4015 ± 1539 Gangzyklen (GC) präoperativ zu 3724 ± 1543 GC nach sechs Wochen (p=0.183). Erst nach 3 Monaten kam es zu einer signifikanten Aktivitätssteigerung von 4756 ± 1733 GC (p kleiner 0.01), welche noch nicht den Anforderungen für einen aktiven Lebensstil entsprach. Andere Faktoren wie arthrosebedingte Schäden, der Rehabilitationsumfang oder Komorbiditäten scheinen wichtige Einflussgrößen für eine adäquate körperliche Aktivität zu sein.

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.
