Salvage of Failed Hip Fracture Fixation
Bibliographic record
Abstract
Nonunion of fractures about the femoral neck and intertrochanteric hip regions is uncommon. Patients who develop nonunions of these fractures typically exhibit marked pain and disability, thereby presenting a treatment challenge to the orthopaedic surgeon. Factors that guide the choice of salvage treatment include the anatomic site of the nonunion, the quality of the remaining proximal bone and articular surface, and patient factors (such as age and activity level). In the younger patients with a well-preserved hip joint, treatment typically involves revision internal fixation with or without osteotomy or bone grafting. However, in older patients, it is more common to encounter poor remaining proximal bone stock or a badly damaged hip joint from hardware cutout. As such, conversion to hip arthroplasty is intended to help effectively restore function and relieve pain. With respect to salvage procedures for the femoral head, the major challenges in decision making include the choice of both internal fixation device and accurate preoperative planning. The challenges involved in planning to convert to hip arthroplasty include the need for acetabular resurfacing, selecting the femoral implant, and managing discontinuity of the greater trochanter. Furthermore, there are additional technical challenges that may be encountered, such as broken hardware, deformity, and femoral bone defects. Overall, salvage of nonunions of femoral neck and intertrochanteric hip fractures in properly selected patients can provide patients with good to excellent results.

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.
