Purpose: AO type C distal humerus fractures are difficult to deduct and repair because of the difficulty of the rectal anatomy and the smallness of broken bone parts. Although the parallel plaque technique for Humerus distal breaks is biomechanically superior, we assume that in clinical conditions the ortogonal plaque technique is as reliable and effective as the parallel plaque method for Type C humerus breaks. Instruments and Methods: Between 2012-2018, 36 patients who were operated due to AO type C distal humerus breach and who meet the criteria for admission to the study were considered retrospective. Parallelly 20 patients, 16 patients were applied ortogonal (medial and posterolateral) plaque. All patients were diagnosed with LC-DCP plaques. The following data for both groups were collected: age Gender side before surgery period smoking habits broken type additional injury cooking time track time Quick DASH, Mayo rectum and VAS scores capture power rectum EHA extension loss and final control complications were assessed. Results: There was no statistically significant difference between the groups in terms of age, gender, side, time before surgery, smoking habit, type of break and additional injury (P> 0.05). There were no statistically significant differences between the groups in terms of Quick DASH, Mayo rectum or VAS scores, capability, rectum EHA, extension loss, cooking time, postoperative heterotrophic ossification, rectum and olecranon cooking, postoperative neuropractic or other complications (P > 0.05). There was a statistically significant difference between the two groups in terms of Ulnar nerve transposition (P<0.05). The result is that there is no functional, radiological or complicated advantage in the treatment of type C distal humerus fractures between commonly used parallel plaque and ortogonal plaque in literature. The surgeon can safely use both techniques, depending on the type of break and how both columns are broken.
