The Lateral Decubitus Approach for Complex Proximal Femur Fractures
Bibliographic record
Abstract
SUMMARY: Unstable intertrochanteric or subtrochanteric fractures with significant proximal or distal extension or comminution are often a challenge for achieving stable fixation. In recent years, locked proximal femoral plates have been developed that aid fixation of these complex fractures often permitting the biological advantages of minimal contact or minimally invasive application. Although previously described with success using a standard lateral approach in the supine position, we describe a lateral decubitus position for the locked plating of proximal femur fractures. We have found that lateral positioning neutralizes the gravitational forces acting on the bone and soft tissues, facilitating reduction and exposure while continuing to be compatible with intraoperative image intensification. We present lateral positioning as a technical trick for anatomic and stable reduction of complex proximal femur fractures with proximal femoral locking plates and present a series of 10 cases that were treated with this combination of approach and internal fixation.

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.
