Treatment of Pathologic Femoral Neck Fractures with Modified Pauwels??? Osteotomy
Bibliographic record
Abstract
UNLABELLED: Treatment of pathologic femoral neck fractures secondary to extensive lesions of fibrous dysplasia and simple bone cysts has been controversial. We think that modified Pauwels' intertrochanteric osteotomy and osteosynthesis can result in sound healing of the lesion and of the fracture, with no recurrence, low complication rates, and good functional results. Seven patients were treated with a uniform approach consisting of biopsy (Stage I) and osteotomy with osteosynthesis (Stage II). Curettage of the lesion and bone grafting were not done. The average followup was 79.28 months (range, 32-142 months). All of the fractures and osteotomy sites healed in means of 14 weeks (range, 12-16 weeks) and 9.1 weeks (range, 8-10 weeks), respectively. All fibrous dysplasia lesions healed radiologically. Grade IV radiographic healing was seen in both patients with simple bone cysts after 35 and 92 months. Using the Musculoskeletal Tumor Society functional evaluation and Toronto Extremity Salvage Score, all the patients had good to excellent results. Complications such as infection, local recurrence, refracture, femoral neck deformity, osteonecrosis of the femoral head, and growth arrest of capital femoral physis were not seen. In addition to biomechanical advantages, the procedure seems to have had a biologic role in healing of the fracture and of the lesion by initiating osteogenesis to replace the defect with new bone. LEVEL OF EVIDENCE: Therapeutic study, Level IV (case series--no, or historical control group). See the Guidelines for Authors for a complete description of levels of evidence.

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.
