Cumulative incidence demonstrated a nonlinear temporal pattern, with most events occurring early after reduction: 87% within the first 14\u2009days, with apparent peaks at days 3\u20134 and 7\u201314. In multivariable analysis, initial lateral displacement percentage &gt;85% (hazard ratio [HR] 3.52, 95% confidence interval (CI): 1.82\u20136.83) and severe soft-tissue swelling (HR 3.08, 95% CI: 1.61\u20135.89) were independently associated with redisplacement, whereas Gartland classification was not.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Redisplacement risk after nonoperative management of pediatric SCHFs appears concentrated in early post-reduction periods.
