Abstract
Aims: This study aimed to evaluate the efficacy of porous titanium acetabular augments in primary total hip arthroplasty (THA) for reconstruction of superolateral acetabular bone defects in patients with Crowe II or higher classes of developmental dysplasia of the hip (DDH) or rapidly destructive coxopathy (RDC). Methods: We conducted a retrospective evaluation of 27 patients (30 hips) who underwent primary THA using cementless cups and porous titanium acetabular augments. The follow-up periods ranged from two to 11 years, with a mean of 5.0 years. The cohort included 22 females (24 hips) and five males (six hips), with a mean age of 67 years (45 to 83) at the time of surgery. Results: At the final follow-up, there was no radiological evidence of loosening or radiolucency around the cups and augments, indicating successful biological fixation in all cases. Clinically, there was a significant improvement in the Western Ontario and McMaster Universities Osteoarthritis Index score, which improved from a mean of 39.1 (SD 14.7) preoperatively to 5.1 (SD 6.4) postoperatively. Conclusion: The use of cementless cups and porous acetabular titanium augments in primary THA for patients with DDH and RDC can lead to considerable clinical improvements and reliable biological fixation, suggesting their potential as a viable solution for managing challenging acetabular defects in these conditions.

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 it
