AB022. SOH25_AB_128. Novel post-free traction technique provides safe surgical exposure in paediatric and adolescent and femur fracture surgery
Bibliographic record
Abstract
Background: The traction table is used for numerous lower extremity procedures including hip and femur fractures, deformity correction, and hip arthroscopy. However, standard traction is not without risk; injuries are common and include neuropraxias, pressure injuries, well leg compartment syndrome, and rotational malreduction. This study aims to outline our experience using a post-free traction table in the management of paediatric femur fractures and report on early functional and radiographic outcomes and complications. Methods: A retrospective review of consecutive patients treated with post-free traction from 2019–2023 was performed. Patients who presented with a diaphyseal femoral fracture and treated surgically using a post-free traction table were included. Exclusion criteria included inadequate clinical records. Variables including operative time, adequacy of traction, use of “bail-out” perineal post, intra- and post-operative complications, fixation strategy, and fracture union at follow-up were collected for reporting. Results: Twenty-five traumatic and three pathological femur fractures met inclusion criteria. Adequate traction was reported in all cases using the post-free traction table and no cases reported pudendal nerve palsy or related injuries. Median (confidence interval) operative times including positioning were 2.5 (2.3–3.4) hours for traumatic and 2.7 (1.4–4.3) hours for pathological femur fractures. No complications related to mal-rotation, malunion, or nonunion were documented. One patient developed leg calf swelling postoperatively and one patient developed post-operative left arm neuropraxia. Conclusions: Post-free traction for the management of paediatric femoral fractures is safe, reliable, and can be considered an excellent alternative to classic perineal post-based traction. No injuries related to perineal pressure were observed.

How this classification was reachedexpand
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.
