Percutaneous Humeral Plating of Fractures of the Proximal Humerus: Results of a Prospective Multicenter Clinical Trial
Bibliographic record
Abstract
OBJECTIVES: To evaluate the safety and functional outcome of a recently described surgical technique of percutaneous plating for proximal humerus fractures. DESIGN: Prospective clinical trial. SETTING: : Two urban Level 1 university trauma centers. PATIENTS: From February 2002 to December 2003, 34 consecutive patients underwent surgery by 5 trauma surgeons from 2 teaching hospitals. Twenty-seven patients had 1-year follow-up. INTERVENTION: The technique involved 2 minimal incisions with a lateral deltoid split and a more distal shaft incision. A proximal humerus-specific locking plate was implemented. MAIN OUTCOME MEASUREMENTS: DASH (disabilities of the arm, shoulder, and hand) and Constant-Murley evaluation scores were used for functional evaluation. The presence of complications was noted. RESULTS: Specifically, there were no axillary nerve injury injuries and no loss of reduction. The average Constant score at 1 year was 82 and the DASH score was 26. CONCLUSION: This study demonstrated that the functional outcome results correspond to a normal age-adjusted score signifying an acceptable result.

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.
