The radial head fractures is one third of all elbow fractures in adults (1), so X-rays or scans are taken, however there is no literature that support the realization of tomography as additional study, so ask ourselves: tomography elbow changes the behavior previously radiograph taken with radial head fractures? An agreement study, where X-rays and CT scans are evaluated by two elbow surgeons, patients with fracture of the radial head in the emergency room valued on two tertiary hospitals of Bogotá from January 2011 to January 2013. 116 medical histories were reviewed, 99 met the criteria, radiographs were reviewed by two orthopedist elbow surgeons who performed ranking Mason getting a κ 1 (P 0. 00), treatment proposal post X-ray κ 0. 934 (P 0. 000, 95% CI 0. 85, 1). Post-scan with κ 0, 934 (p˂ 0, 000 IC95% 0. 85, 1). Concordance intra-orthopedist pre- and post-scan review, has a behavior change in Orthopedist 1 in 32. 6% (κ 0. 674 p˂ 0, 00 IC95% 0. 52, 0. 818) and orthopedist 2 in 36% (κ 0. 64 p˂ 0, 00 IC95% 0. 452, 0. 792). Patients were divided into Mason I, II and III, with substantial concordance in Mason I and III, while Mason II was an acceptable agreement which means that the use of elbow CT scans changes the behavior in general but especially in patients Classified Masson II.
