Risk Factors for Avascular Necrosis After Pediatric Hip Dysplasia Surgery: A Meta-Analysis

A systematic review and meta-analysis of 16 studies involving 1,631 pediatric patients (1,941 hips) with developmental dysplasia of the hip (DDH) following surgery. The study, authored by Zhuotao Guo and updated in April 2026, identifies independent risk factors for postoperative avascular necrosis (AVN). Data were analyzed using Stata version 15.1, with a search conducted up to May 1, 2025.

Use Cases

• Training risk prediction models based on identified factors like absence of ossific nucleus.
• Informing clinical decision-making for DDH surgery based on meta-analysis results for IHDI classification grade.
• Designing future clinical studies on pediatric orthopedic complications based on the aggregated evidence.
• Benchmarking surgical outcomes against the reported incidence of AVN (468 hips).

Strengths

• Includes aggregated data from 16 studies, providing a synthesized evidence base.
• Reports specific odds ratios and confidence intervals for identified risk factors.
• Has a registered systematic review protocol (PROSPERO CRD420251135105).
• Released under a permissive CC-BY-4.0 license.

Limitations

• The primary data file is a 22.3 KB DOCX document, which is a small text summary, not the underlying patient-level data.
• Column-level documentation for any underlying data is absent; field semantics must be inferred from the article.
• Row count for any potential tabular data is unknown, which may limit suitability assessment.
