Objective: The aim of our study is to evaluate the results of our patients treated with double plating in parallel or orthogonal configuration after adult distal humerus fractures.

Material and Method: Between January 2013 and December 2020, 31 patients with adult distal humerus fractures who were treated with double plates in our clinic were retrospectively analyzed. Demographic, clinical and radiologic information of the patients were recorded by scanning their files. Clinical results were evaluated by transferring to the MAYO Elbow Performance Scoring System(MEPS).

Results: 45.2% (n =14) of the patients were female, 54.8% (n =17) were male, and the mean age was 49.8±22.32 (20-85) years. The most common reason for admission was simple fall in 48,4% (n =15) patients. According to the AO/OTA classification, the most common fracture type was type C1 fracture in 51,6% (n =16) patients. The mean time to surgery was 4.5±4,95 (0-25) days. The mean MAYO score of the patients operated on in the first 2 days was significantly higher than the patients operated on after 2 days (p :0.022). Osteosynthesis was performed with parallel plates in 15 patients and orthogonal plates in 16 patients. There was no significant difference in clinical outcomes between parallel and orthogonal plating groups (p >0.05). The mean MAYO score of the patients was evaluated as good with 87.4±18.48 (40-100) points.

Conclusion: In the treatment of distal humerus fractures, anatomic joint restoration and parallel or orthogonal rigid fixation with double plates is a suitable treatment method that can provide good and excellent results at a high rate. The configuration selection can be preferred according to the surgeon\'s clinical experience and implant suitability.
