Acute Compartment Syndrome Following Non-Displaced Proximal Ulnar and Distal Radial Fractures in a Four-Year-Old Girl
Bibliographic record
Abstract
Acute compartment syndrome (ACS) is a rare but limb-threatening emergency in children, usually associated with displaced fractures, crush injuries, or high-energy trauma. Prompt recognition and fasciotomy are essential to prevent permanent disability. An unusual case of ACS after non-displaced fractures is presented, challenging traditional risk factors. A healthy 4-year-old girl presented 12 h after a 2-m fall with severe forearm pain, swelling, an absent radial pulse, delayed capillary refill (3 - 4 s), and cold digits. Radiographs showed non-displaced proximal ulna and distal radius fractures. Emergency fasciotomy was performed based on clinical findings of ACS. ACS can occur in children after non-displaced fractures, even without conventional risk factors. Clinicians should rely on careful neurovascular assessment and clinical suspicion rather than fracture type or mechanism alone. Early recognition and surgical intervention are critical to preserve limb function.

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.
