Background: We introduce several methods for fixation of unique Mayo type II olecranon fractures with the coronal plane fragment (CPF) including the entire coronoid process and report the radiological and clinical results through a case series. Materials and Methods: 12 patients were operated using this method with a mean age of 44 years. CPFs were fixed with concurrent fixation by a locking plate screw for the olecranon in three patients (method 1), cerclage wiring in six patients (method 2), a mini plate in two patients (method 3), and a double-locking plate (method 4) in one patient. We accessed the fragment through an additional medial coronoid approach after identifying the olecranon fragment through a dorsal approach (methods 1–3). In method 4, the CPF was fixed through a dorsal approach between the comminuted metaphyseal fragments. Results: With the exception of one patient with delayed union, all patients had achieved union at 3-month followup. The mean flexion extension arc was 125°. The mean pronation/supination was 72.5°/71.7° (range, 60-80°/60-80°). The mean visual analog scale score for elbow pain was 0.92 (range, 0-2), and the mean Mayo Elbow Performance Score was 86.7 (range, 80-90). The mean Disabilities of the Arm, Shoulder, and Hand score was 10.2 (range, 4-14). There were no major complications. Conclusion: A thorough preoperative understanding of the fragment patterns and preparation of tools for adequate reduction and fixation are necessary for satisfactory clinical and radiological outcomes. However, further comparative trials of conservative management versus surgery for CPF fixation, and any differences in outcomes according to the CPF fixation options, are required.
