Bilateral total hip Arthroplasty in Severe Hereditary Multiple Exostosis: A report of two Cases
Bibliographic record
Abstract
Staged bilateral hip arthroplasties were carried out in two patients with osteoarthritis of the hip secondary to the development of hip dysplasia in Hereditary Multiple Exostosis (HME).Both patients had near ankylosis of their hips with pain and difficulty in performing activities of daily living. A proximal femur replacing prosthesis was implanted through an extended trochanteric osteotomy, with preservation of as much proximal bone stock as possible. At latest followup (two to five years), there was a sustained improvement in range of motion and symptoms. The Harris Hip Scores improved from 25 and 31 to 83 and 78. The Toronto Extremity Salvage Scores improved from 49% and 55% to 88% and 75%. Radiographs show bony ingrowth and healing of the trochanteric fragments. In severe HME, hip arthroplasty with replacement of the proximal femur provides good symptomatic relief and return of hip joint movement.

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.
