In proximal-to-mid humeral chronic osteomyelitis, complex anatomy, abundant musculature, and limited tourniquet feasibility may cause diffuse bleeding, impaired visualization, and prolonged surgery. Although tranexamic acid (TXA) is widely used for orthopaedic blood management, its infection-control safety in infected bone debridement remains unclear. We evaluated preoperative intravenous TXA in this setting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single-center retrospective cohort study included patients undergoing debridement for chronic osteomyelitis of the proximal or mid-humerus between January 2020 and March 2025. Patients were grouped by preoperative intravenous TXA use; the TXA group received 1.0\u2005g approximately 30\u2005min before surgery. Primary outcomes were second-stage frozen-section neutrophil count, unplanned repeat debridement, infection recurrence, and venous thromboembolic events.
