Tel: 0553650795 Objective Mob: 01093445108 The aim of this study is to evaluate fixation of supracondylar intercondylar humerul fractures E-mail: [email protected] by anatomical distal humeral plates. Functional results will be assessed with Mayo elbow per- formance (MEP) scores. Materials and Methods A prospective study of 20 patients with supracondylar intercondylar humeral fractures was treated by anatomical distal humeral plates in the department of Orthopaedics at Al-Azhar university hospitals between the period of October 2016 till September 2017. Variables of each patient were recorded The Egyptian Orthopedic Journal; 2019 and analyzed with respect to age, sex, fracture type, mode of injury, limb involvement, associated supplement (2), December, 54: 1-7 injuries, follow up, complications and final outcomes. These patients were followed up at different intervals i.e. at every week for first 1 months, then interval of 1 month for next 6 months and then at 3-month interval. Results As regard 20 patents in this study, the result of our study showed 8 cases (40%) had excellent result, 8 cases (40%) had good result, and 4 cases (20%) had poor result. The Mean ±SD of score was 83.5 ± 17.6. Conclusion Locked compression plates have been popularized that utilize fixed angle screws that are be- lieved to provide superior fixation. They have an additional advantage of neocortical screw placement that avoids risk of screw tips projecting into the joints. These locked compression plates and distal humerus plates are more useful in patients with osteoporotic bones, metaphy- seal commination and very low type of intra-articular fractures.
