This article covers everything related to radial cup fractures, which account for 4% of anatomical fractures. Despite advances and innovations in trauma management, unstable radial dome fractures challenge proper management until the orthopedist achieves the best results. The objective of this thesis is to evaluate the functional evaluation in the postoperative follow-up of these patients using a functional scale that gives us a perspective that favors some of these procedures. As a result, a median age of 37 years was found in the patients, with a slightly higher prevalence in women, 62.5% with left elbow and traffic injuries, which accounted for more than half of the cases, 62.5% with Mason IV radial dome fractures and 37.5% with Mason III type. Open reduction and osteosynthesis were performed in 62.5% of patients, while arthroplasty was performed in the remainder. No associations were found with functional results in relation to the type of surgery performed or other variables in the bivariate analysis. josha.org
