Reliability of hip range of motion using goniometry in pediatric femur shaft fractures.
Bibliographic record
Abstract
INTRODUCTION: The purpose of this study was to determine the interrater reliability of the assessment of range of motion of the hip joint through goniometry. METHODS: We included children aged 4 to 10 years with a femoral shaft fracture, from 4 study sites, who had had either an early hip spica cast or an external fixator. An assessor blind to treatment received at each site measured range of hip joints motion, using a standardized goniometric technique at 15 and 24 months postfracture. RESULTS: The intraclass correlation coefficient (ICC) was used to quantify concordance or agreement. Most ICCs for the different aspects of hip range were between 0.2 and 0.5, indicating only slight agreement. The most reliable measure was hip flexion, with an ICC of 0.48 (95% confidence interval 0.29-0.63). CONCLUSION: Goniometric measurement, using standardized protocols for the hip, has low reliability. Only when differences in rotation exceed at least 30 degrees and in flexion-extension exceed 50 degrees should clinicians conclude that true change has occurred.

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.
