Complications after tibial tubercle traction and femoral neck fractures in children: a case report
Bibliographic record
Abstract
Background: Genu recurvatum and femoral neck fracture in children are very rare, and relevant literaturewas reported. However, there were no reports on avascular necrosisafter internal fixation of femoral neck fractures in children, and genu recurvatum and tibial dysplasia after tibial tubercle traction.Case presentation: In this case, a 32-year-old female patient suffered from a femoral neck fracture at the age of 10. The tibial tubercle traction was applied in the conservative treatment, and closed reduction and internal fixationwere adopted after the failure of the conservative treatment. When the patient came to our hospital for the treatment of hip and knee joint pain for 20 years, the doctor discovered that the patient had severe genu recurvatum and avascular necrosis. We adopted staged treatment for the patients. First, the left hip artificial joint replacement was performed due to the femoral head necrosis. After the operation, the pain in the left hip disappeared. Three months later, the patient underwent the combination of tibial osteotomy and tibial tubercle transposition to treat genu recurvatum. One year after the operation, the anterior and lateral radiographs of the knee joint displayed that the osteotomy area healed well, without complications such as fracture nonunion and infection. The appearance of the knee joint returned to normal. According to UCLA Activity Score and WOMAC (The Western Ontario and McMaster Universities) Osteoarthritis Index, the patient's activity and function levels were assessed, and the postoperative scores were significantly improved compared with preoperative scores.Conclusion: Pediatric Femoral Neck Fractures should be treated promptly with surgery and long-term follow-ups. Total hip replacement is an effective method for the treatment of end-stage femoral head necrosis. Meanwhile, tibial traction should be avoided for children with lower extremity fractures, because it may damage the tibial growth plate, thus leading to the early closure of the metaphyseal region in children, and genu recurvatum. The modified surgery for the treatment of genu recurvatum is simple to operate and can avoid patella Baja, so it has a strong healing ability in the osteotomy area. The results of the surgery technique were ideal in this case.P

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.
