Background: Fractures of the radial head are common ,constituting approximately one-third of all elbow fractures. These fractures typically occur when an axial load is applied to the forearm, causing the radial head to hit the capitellum of the humerus. The severity of these injuries runs the gamut from minimally displaced fractures needing minimal treatment to those with major displacement or comminution, requiring surgical fixation, excision, or replacement. In two-part partial articular fractures of the radial head, fixation can be achieved by lag screws. The thread pulls the opposite bone fragment towards the head of the screw placing the fracture ends under compression. Mini fragment 1.5 mm or 2.0 mm screws, or headless compression screws (Herbert or similar screws) are used. Aim of the work: Evaluating the effectiveness of treating Mason II & III radial head fractures through the fixation with mini screws(17) on 20 patients and the outcome of operatively treated Mason II & III radial head fractures(18), this enables the discovery of complications and can lead to modifications in treatment.(19). Primary outcome is maintenance of reduction of fracture and elbow stability and secondary outcome is functional evaluation of elbow by Dash & Mayo elbow performance index. Patients and methodology: this study was conducted on 20 radial head fracture treated with screws and were evaluated regarding union range of motion and MEPS. Results: According to Mayo elbow performance score (MEPS) the clinical results were graded as excellent in 11 patients (55%), good in 6 patients (30%), fair in 1 patients (5%) and poor in 2 patients (10%). The average Mayo elbow performance score was 86
