Inclusion criteria included traumatic nonpathological elbow fracture dislocations. Patients were randomized 1:1 to receive either intraoperative TXA or no additional treatment.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Outcome Measures and Comparisons:<\/jats:title>\n            <jats:p>The primary outcome was the occurrence of HO, defined by new bone formation observed in radiographic exams during postoperative follow-ups. Secondary outcomes included the presence of clinically relevant HO, reoperation rate due to symptomatic HO, and time to HO reoperation. Compared were patients who received TXA with controls.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>Out of 47 patients with elbow fracture dislocations who completed the follow-up, 23 (49%) received TXA prophylaxis while 24 (51%) were controls. The average age was 51.2 years (range, 18\u201377 years) with a mean follow-up of 12.9 months (range, 6.11\u201334.2). In the TXA group, 11 (47.8%) were men and 12 (52.2%) were women, while in the control group, 14 (58.3%) were men and 10 (41.7%) were women. HO was observed in 30% of patients, primarily around the radial head (71%). In this study, 43.5% of patients in the TXA group developed HO compared with 16.7% in the control group. The differences in HO formation suggest a potentially higher risk in the TXA group (relative risk = 2.6, 95% 1.0 to 8.5, <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.06). Clinically relevant HO led to reoperation in 2 of 10 (20%) patients in the TXA group, while none of the patients in the control group required reoperation, resulting in an overall reoperation rate of 14.3% in the study cohort.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>This prospective trial identified a possible increased risk of HO formation in patients receiving TXA, however, with the sample size available a statistically significant difference was unable to be detected. These findings highlight the need for further research emphasizing larger prospective comparative studies to assess TXA's impact on HO. A deeper understanding of this relationship will enable clinicians to balance TXA's potential risks and benefits more effectively, optimizing outcomes in orthopedic surgery.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n            <jats:p>Therapeutic Level I.
