Introduction: Acute osteomyelitis is a bone infection that mainly affects children and generally has hematogenous spread, sometimes associated with trauma. The etiology is influenced by factors such as age, immune status, and comorbidities. In most cases, the main etiologic agent is Staphylococcus aureus. Timely diagnosis is important to avoid sequelae in the medium or long term. Objective: To describe the epidemiological characteristics of a group of patients with acute osteomyelitis. Methods: A retrospective review of the clinical records of patients discharged from the pediatric service of the Institute of Tropical Medicine was carried out between January 2016 and December 2020, with a diagnosis of acute osteomyelitis. Results: Men with osteomyelitis correspond to 67.8% of the total of 59 registered cases, in terms of signs and symptoms, pain, swelling and functional impotence were predominant, fever was documented in 49 (83.1%) patients, a history of surgery was recorded in 37 (62.7%) of the patients and complications in 42 (71.2%) of the patients, the most frequent complication was chronic osteomyelitis The most frequent anatomical site was the lower limbs. Empirical treatment was performed with 3G cephalosporins in 72.9% of the patients, either alone or in combination with clindamycin or vancomycin. One patient with M. tuberculosis isolation received HRZE treatment. Some germ was isolated in 44 patients (74.5%), the predominant microorganism was Staphylococcus aureus in 81.8%, half (52.3%) corresponded to MRSA. A high resistance to oxacillin of 55.8% and a only patient resistant to clindamycin (2.2%). Conclusion The findings were similar to those reported in the literature in terms of etiology, affected anatomical site, and antibiotic coverage.
