20-Year Experience in Total Primary Hip Arthroplasty in Patients Under 50 Years with Inflammatory Rheumatic Diseases: Functional Results, Complications and Survival
Bibliographic record
Abstract
Introduction: Total Hip Arthroplasty (THA) is an option in young patients with comorbidities of inflammatory rheumatic diseases such as juvenile idiopathic arthritis, rheumatoid arthritis, femoral avascular necreosis, among others.Currently, approximately 280,000 cases of primary THA and more than 50,000 revision surgeries are reported annually in the United States.It is expected that the demand for THAs will continue to increase due to the improvement in the quality of life.Objective: Evaluate the survival of THA in patients under 50 years of age with rheumatic diseases who attend "The National Institute of Medical Sciences and Nutrition Salvador Zubiran" in a period from 2000 to 2020, as well as to explore their sociodemographic characteristics.Methods: Information was collected retrospectively through the clinical records of 295 patients who received total hip arthroplasty between 2000 and 2020.The sociodemographic characteristics of the population were evaluated, as well as comorbidities, complications of the intervention, and functionality using: Visual Analogue Scale (VAS), Harris Hip Score (HHS), Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), Oxford Hip Score (OHS), and Total Hip Arthroplasty Survival. Results:We were able to observe that the probability of survival for THA is 98% at five years, 93.8% at ten years, 81% at fifteen years, and 61% at twenty years. Conclusions:In a retrospective cohort of 171 patients, the outcomes of THA, such as the prevalence of comorbidities and survival, are comparable to what has been previously reported in the literature.

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.
