Effect of buried vs. exposed Kirschner wire osteosynthesis on phalangeal, metacarpal and distal radial fractures: A systematic review and meta-analysis
Bibliographic record
Abstract
BACKGROUND: During Kirschner wire osteosynthesis for phalangeal, metacarpal and distal radial fractures, a key clinical decision is whether to leave a Kirschner wire exposed or bury it beneath the skin. Therefore, we conducted a meta-analysis to evaluate the clinical effect of buried and exposed Kirschner wire osteosynthesis on phalangeal, metacarpal and distal radial fractures. METHODS: PubMed, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched and clinical trials that evaluated buried and exposed Kirschner wire osteosynthesis for phalangeal, metacarpal and distal radial fractures were identified. Methodological qualities of studies were assessed by using the Cochrane Collaboration tool and Newcastle-Ottawa Scale. Publication bias was detected using Begg's test and Egger's test. Sensitivity analyses were performed by excluding one study at a time to determine whether overall results were reliable. RESULTS: Two randomized controlled trials (RCT) and five case-controlled studies involving 1446 patients were included in the analysis. Sensitivity analyses indicated that the results of each study were statistically robust. Begg's test or Egger's test revealed no significant publication bias. Our meta-analysis indicated that exposed Kirschner wire osteosynthesis had a significantly higher infection rate than its buried counterpart. Additionally, buried Kirschner wire osteosynthesis resulted in a significantly higher rate of Kirschner wire removal in operating room than the exposed one. Our meta-analysis exhibited no statistical differences between the two procedures in the rate of early pin removal. CONCLUSIONS: Meta-analysis of available RCTs and case-controlled studies demonstrated that buried Kirschner wire osteosynthesis had a lower infection rate but tended to lead to more frequent Kirschner wire removal in the operating room as compared to its exposed counterpart. TRIAL REGISTRATION: PROSPERO (CRD42018105249).

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.
