Fixation of fibular head avulsion fractures with the proximal tibiofibular screw: Technique guide and clinical experience
Bibliographic record
Abstract
Background: Fibular head avulsion fractures are often associated with posterolateral corner injuries. Conventional fixation have consisted of transosseous or anchor-based suture techniques. Purpose: This technique paper reports on the use of a cannulated screw for fixation of fibular head avulsion fractures by a single surgeon at a tertiary referral center. Methods: Thirty-seven patients underwent open reduction and internal fixation of fibular head avulsion fractures between 2006 and 2022. Results: At final follow up (mean 3.5 years ± 2.5) all fractures went on to bony union. All patients regained functional range of motion with mean extension of 1 degree (median 0 degrees, range 0 to -5 degrees) and mean flexion of 121 degrees (median 127.5 degrees, range 90 to 135 degrees). Conclusion: Our results suggest that a cannulated screw across multiple cortices provides robust fixation and allows for early motion.

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.
