Prospective study assesses perfusion changes in infants after hip reduction, suggesting implications for injury risk.

This study aims to evaluate intraoperative femoral head perfusion changes after surgical reduction for infantile DDH.
Conducted a prospective study with infants aged 4 to 18 months undergoing surgery for DDH.
Utilized contrast-enhanced ultrasound to assess perfusion before and after surgical reduction.
Performed statistical analysis to explore relationships between casting position and perfusion changes.
Found significant lower perfusion index in 79.4% of hips post-surgery (p = 0.003).
Identified most significant decreases in perfusion in the central femoral head region (p = 0.002).
Observed correlation between axial abduction and decreased perfusion index (r = 0.35; p = 0.04).

Kebeh et al. (2026) studied this question.
