Tricortical Bone Grafts for Treatment of Malaligned Tibias and Fibulas
Bibliographic record
Abstract
UNLABELLED: Malunions and malaligned nonunions of the tibia and fibula after fracture alter limb function and can be corrected only with surgical intervention. We sought to determine whether using tricortical portions of the iliac crest in conjunction with osteotomy and internal fixation could successfully treat malunions and malaligned nonunions of the tibia and fibula. Seventeen patients with either a malunion or a malaligned nonunion of the tibia or fibula were treated with an osteotomy, deformity correction, and placement of an autogenous iliac crest tricortical bone graft with open reduction and internal fixation (ORIF). The minimum followup was 3 months (average, 32 months; range, 3-118 months). Sixteen patients (94%) had clinical and radiographic evidence of healing at an average of 99 days (range, 43-229 days). Major complications occurred in four patients; one had a persistent nonunion, two had wound infections, and one underwent resection of the distal fibula for subsequent development of fibulotalar arthrosis after ankle arthrodesis. Minor complications occurred in two patients, one tendinitis and one persistent malunion. There were no complications at the iliac crest bone graft site. Autogenous iliac crest tricortical bone grafts, when used in conjunction with correction of alignment and stable internal fixation, are a reasonable option for treatment of nonunions and malaligned nonunions of the tibia and fibula. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

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.
