Efficacy of Short-term Teriparatide for Hip Osteonecrosis
Bibliographic record
Abstract
To the Editor: Osteonecrosis of the femoral head is the result of the lack or decrease of blood supply to the bone leading to bone and cartilage cellular death, fracture, and finally collapse of articular surface1. The pathogenesis is still unclear, but it seems that it is the result of a variety of traumatic and atraumatic factors such as genetic predisposition and metabolic factors. Risk factors are high-dosage glucocorticoids, alcohol abuse, venous stasis, adipocyte hypertrophy, alteration of circulating lipids, and other diseases that facilitate intravascular coagulation and thrombus formation2. Nonsurgical treatment is limited and consists of physical therapy and rehabilitation, protected weight-bearing, hyperbaric therapy, and the use of nonsteroidal antiinflammatory drugs (NSAID), bisphosphonates, nifedipine, and lipid-lowering agents3. Unfortunately, these treatments have shown not a real efficacy, but only partial results on pain or delaying fracture and articular collapse4. Teriparatide (TPT), a recombinant synthetic version of the human parathyroid hormone (PTH), is a bone anabolic … Address correspondence to Dr. F.

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.
