Open anterior hip dislocation combined with infection and injury of the common femoral artery and vein: A case report and literature review
Bibliographic record
Abstract
RATIONALE: Open anterior hip dislocation resulting in vascular injury is extremely rare and is a severe orthopedic emergency that can potentially lead to limb necrosis and even life-threatening consequences. PATIENT CONCERNS: A 51-year-old woman presented to our hospital with an open anterior dislocation of the left hip secondary to a fall from height. The patient had a severe infection in the left inguinal area; at presentation, there was dislocation of the femoral head lasting for the past 5 days. Doppler ultrasound revealed left common femoral vein thrombosis. DIAGNOSES: The patient was diagnosed with a multiple-injury patient with an acetabular fracture, femoral head fracture, and open anterior dislocation of the hip with vascular injury and infection. INTERVENTIONS: After placement of an inferior vena cava filter, the reduction was performed under general anesthesia. The common femoral artery ruptured during the process. After suturing, continuous drainage was maintained. During the subsequent treatment, the infection gradually eroded the common femoral artery and formed a pseudoaneurysm. Lower limb vascularity was restored by autologous saphenous vein grafting, repeated debridement, and sensitive antibiotics. OUTCOMES: The infection of the patient was gradually controlled, and the lower limb was successfully preserved. During the 1-year follow-up, the patient returned to normal life without disability. LESSONS: From this rare case, we suggest that a therapeutic approach should be evaluated after adequate exclusion of deep vein thrombosis to prevent thromboembolic events. Moreover, gentle reduction operation, thorough debridement, and timely infection control are essential to prevent complications and improve the functional prognosis of patients.

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.
