Closed Reduction Internal Fixation Rates and Procedure Times for Metacarpal Fractures Treated in a Minor Surgery Area Before and After the Introduction of a Mini C-Arm Unit
Bibliographic record
Abstract
BACKGROUND: Mini C-arm units are compact, mobile, fluoroscopic imaging systems designed for real-time imaging of the extremities. They deliver the lowest possible radiation exposure to the patient and physician while minimizing operator effort and inconvenience. METHODS: A retrospective chart review was undertaken for consecutive metacarpal fractures requiring internal fixation treated in the minor surgery centre before (n=100) and after (n=100) the introduction of the mini C-arm. Open versus closed approach, procedure time and total operating room time were recorded. RESULTS: Before the introduction of the mini C-arm, the percutaneous rate was 48% and the average procedure and total operating room times were 55 min and 102 min, respectively. After mini C-arm implementation, the percutaneous rate increased to 59% and the average procedure and total times were 36 min and 78 min, respectively. CONCLUSIONS: The use of a mini C-arm increased the rate of successful closed reduction internal fixation and reduced the procedure time for metacarpal fractures treated in the minor surgery area.

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.
