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 published on figshare in April 2026, identifies independent risk factors for postoperative avascular necrosis (AVN). It includes aggregated results from literature searches up to May 1, 2025.

Use Cases

• Identify key risk factors for AVN based on the reported odds ratios for absence of ossific nucleus, IHDI classification grade III/IV, and secondary procedures.
• Support clinical decision-making for surgical treatment of DDH by synthesizing evidence from 16 studies.
• Inform future research design by providing a quantitative summary of existing literature on this complication.

Strengths

• Includes data from 16 studies covering 1,631 patients and 1,941 hips, providing a substantial evidence base.
• Reports specific, statistically significant odds ratios (e.g., OR=2.60 for absence of ossific nucleus) from multivariate meta-analysis.
• Clear methodology described, including search across four major databases (PubMed, Embase, Cochrane Library, Web of Science) up to May 2025.

Limitations

• The dataset is a 47.1 KB DOCX file containing the review manuscript, not the underlying raw study data.
• Column-level documentation for any underlying data tables is absent; field semantics must be inferred from the text.
• Row count for any potential supplementary data is unknown, which may limit suitability assessment.
