External Fixation of Lower Extremity Injuries in an Austere Environment: A Technique for Safe Application Without the Use of Fluoroscopy
Bibliographic record
Abstract
External fixation is a fundamental technique for the initial care of major extremity trauma. External fixation is used to provide temporary stability in both the damage control setting and environments where resources for definitive fixation are not readily available or definitive fixation is ill-advised. In the austere or resource-constrained environment-particularly in the battlefield setting or in disaster response-external fixation has demonstrated to be a reliable and efficient method for stabilizing the injured extremity without notable disruption of the soft-tissue envelope. Although instruments and implants used for external fixation are highly portable, standard intraoperative fluoroscopy is cumbersome and often unavailable outside of a standard operating room. We present a safe, reproducible technique for external fixator placement without the use of fluoroscopic guidance. In addition to its utility in austere environments, this technique offers several advantages in the standard healthcare setting, particularly in minimizing radiation exposure and allowing for application of an external fixator in settings not optimized for fluoroscopic imaging such as the intensive care unit or combined damage control surgical cases where a nonradiolucent operating room table is used.

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.
