Large pseudoaneurysm arising from the deep femoral artery after hip fracture fixation
Bibliographic record
Abstract
Hip fracture is a common condition of increasing global concern. Vascular injury as a complication after hip fracture repair is rare. A 90-year-old woman developed swelling and pain to her proximal thigh 1 month after uneventful hip fracture fixation. Ultrasound revealed a large pseudoaneurysm of the deep femoral artery, which was successfully treated with transcatheter embolization. Pseudoaneurysms have numerous etiologies. In this case, vascular injury is suspected to be a consequence of proximal migration of the lesser trochanteric fragment. Unfortunately, pseudoaneurysms are often not appreciated due to the nonspecific nature of the presenting symptoms. Diagnosis should be confirmed radiologically and management depends on the location and size of the pseudoaneurysm, as well as patient comorbidities. Pseudoaneurysm after hip fracture fixation is a rare but serious complication. Diagnosis is challenging due to nonspecific symptoms. A high index of suspicion is imperative to prevent life-threatening rupture.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
