Abstract
In North America, and for the most part globally, a cementless acetabular component with adjuvant screw fixation is the preferred technique for revision total hip arthroplasty. However, there are situations that involve massive pelvic bone loss that preclude the use of a cementless cup alone. Options include: i)Enhanced fixation components and augments ii)Specialised constructs (cup/cage) iii)Structural allografts iv)Bone graft substitutes Complex acetabular revisions present the arthroplasty surgeon with challenges that require an approach with more than one solution for all scenarios. While structural allografts have recently fallen out of favour with the increasing use of enhanced fixation components, there would still appear to be a role in the case in which bone stock restoration is a primary goal. The role of bone graft substitutes remains unclear, with supportive basic science data, but limited clinical experience to date. An algorithm will be discussed to assist in prioritising the multiple goals of acetabular reconstruction and one stock restoration.

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; a candidate call from one teacher head, not a consensus.
