Abstract
OBJECTIVE: To develop a new periacetabular osteotomy technique that can be performed safely and reliably using computer-enhanced technology. MATERIALS AND METHODS: This technique uses a modified posterior approach with a trochanteric osteotomy. A 3D surface model is generated from CT data. The osteotomy is planned using custom software developed by our team. A dynamic reference body is fixed to the iliac crest and the pelvis is registered using an optically tracked probe (Optotrak, Northern Digital, Ontario, Canada). A tracked probe is used to mark the osteotomies in three dimensions. The posterior column is osteotomized between the sciatic notch and hip joint. The pubic ramus is osteotomized under fluoroscopic guidance. The acetabular fragment is rotated into a more appropriate position and fixed with pelvic reconstruction plates. Subjective and objective data are collected pre- and postoperatively. RESULTS: This procedure has been performed on eight patients. Average center-edge angle correction has been 17 degrees. The computer and optical guidance system has provided accurate information in seven of eight cases, and there have been no complications. CONCLUSIONS: This technique has enabled us to perform periacetabular osteotomies with safety and predictability. Using this computer-enhanced technique, periacetabular osteotomy may become a more common procedure in the practice of hip reconstruction surgeons.

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
