Open Seymour fractures of the hallux, distinct from closed physeal injuries, lack a clear optimal stabilization strategy when presentation is delayed. To compare reduction maintenance and recovery of interphalangeal (IP) motion after three operative strategies for neglected, open hallux Seymour fractures. Retrospective comparative cohort study. Forty-four children presenting more than 48 hours after injury underwent irrigation, debridement, and nail bed repair, with transarticular fixation (TFx, n=16), extra-articular crossed-wire fixation (EFx, n=17), or no skeletal fixation (NoFx, n=11). Minimum follow-up was 12 months. Categorical outcomes were compared with exact tests; continuous outcomes with Kruskal-Wallis tests and adjusted pairwise comparisons. Loss of reduction occurred in 5/11 NoFx patients versus 0/33 fixed patients (p < 0.001). Median time to full IP motion was 77 days in TFx versus 56 days in both EFx and NoFx (TFx vs EFx, p = 0.002 after adjustment). Physeal alteration occurred in 3/16 TFx, 3/17 EFx, and 7/11 NoFx patients (overall p = 0.027), though pairwise comparisons were not significant. All 5 patients with loss of reduction had physeal alteration, versus 8/39 without (exploratory p = 0.001). Osteomyelitis occurred in 12/44 patients and correlated with longer treatment delay. Fixation was associated with maintained reduction in this neglected, open-injury cohort. Extra-articular fixation showed earlier recovery of full IP motion than transarticular fixation, with no loss of reduction in either fixed group. These findings support joint-sparing fixation when feasible but do not establish causal superiority or identify which fractures may safely remain unfixed. Level III, retrospective comparative study.
