en Orthopedic surgery Research (Original) Background: Talar fractures are uncommon, usually result from high-energy trauma, and may lead to osteonecrosis, non:union:, mal:union:, and post-traumatic osteoarthritis. Objective: To evaluate clinical and radiographic outcomes after surgically treated talar fractures and assess whether the timing of reduction and definitive fixation was associated with those outcomes. Methods: This retrospective observational study included 38 of 53 patients who underwent surgical treatment for a talar fracture between April 2013 and April 2017. Demographic, injury, fracture, and treatment data were obtained from medical records. Radiographs and computed tomography scans were reviewed for :union:, mal:union:, osteonecrosis, and osteoarthritis. Functional outcomes were assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) for pain, and Manchester-Oxford Foot Questionnaire (MOXFQ). Mean follow-up was 38 months (range, 11–70 months). Results: The cohort included 33 men and 5 women with a mean age of 33 years. Osteoarthritis occurred in 52.6% of patients and osteonecrosis in 47.3%; mal:union: and non:union: occurred in 5.3% and 2.6%, respectively. Mean AOFAS, MOXFQ, and VAS scores were 60.3, 67.6, and 4.9. Within the observed surgical interval, we were unable to detect a statistically significant association between treatment timing and osteonecrosis or functional outcome. Conclusion: Complications and functional impairment were common after surgically treated talar fractures. The timing finding should be interpreted cautiously because of the limited sample size and potential selection bias. clinical outcome, radiographic outcome, talar fracture, post-traumatic osteoarthritis, osteonecrosis 13 20 http://tbsrj.mazums.ac.ir/browse.php?a_code=A-10-3548-5&slc_lang=en&sid=1 Mohammad Taghi Peivandi drpeivandy@yahoo.com 100319475328460032108 100319475328460032108 No Orthopedic Research Center, Shahid Kamyab Hospital, Mashhad University of Medical Sciences, Mashhad, Iran Seyed Sadegh Shirdel Dr.s.shirdel@gmail.com 100319475328460032109 100319475328460032109 Yes Orthopedic Research Center, Shahid Kamyab Hospital, Mashhad University of Medical Sciences, Mashhad, Iran Sayyed Hadi Sayyed Hosseinian HoseinianH@mums.ac.ir 100319475328460032110 100319475328460032110 No Orthopedic Research Center, Shahid Kamyab Hospital, Mashhad University of Medical Sciences, Mashhad, Iran Amirsaleh Abdollahi amirsalehabdellahi@gmail.com 100319475328460032111 100319475328460032111 No Mazandaran University of Medical Sciences, Sari, Mazandaran, Iran Mohammad H.
