Eligible patients were women aged 18-40 years with BMI &amp;lt; 30 kg\/m\u00b2 and visceral fat &amp;lt; 13%. All completed 1-year clinical and radiologic follow-up. Postoperative pain, complications, and imaging findings were analyzed using Wilcoxon tests (P &amp;lt; .05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Bicorticality occurred in 15 patients (4.6%), mostly within the first 20 postoperative days. Pain was reported by 41 patients (12.5%), but in 7.9% was related to corset misuse rather than fracture status. Bicorticality correlated with higher visceral fat (12.7% \u00b1 0.5 vs 8.0% \u00b1 0.3; P &amp;lt; .001) and longer operative time (48.9 \u00b1 6.3 vs 43.3 \u00b1 8.3 minutes; P = .01). No hemothorax or pneumothorax occurred. At 1 year, 98.2% demonstrated satisfactory healing; 1.5% showed callus irregularity; and only 1 patient (0.3%) had persistent bicorticality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>RibXcar achieves controlled monocortical fractures with a low bicorticalization rate and predictable consolidation.
