Bicolumnar 90e90 plating of AO 13C type fractures

Abstract

Objective: The aim of this study was to evaluate functional results and complication rate of patients whounderwent medial-dorsolateral plating for intra-articular distal humeral fracture (Müller AO type 13C).Methods: Twenty-four patients (14 men, 10 women; mean age: 47 years) with AO type 13C distal humerus fracture were included in the study. Mean follow-up time was 28 months. Nine patients were in13C1 subgroup, according to AO classiŞcation system, 11 patients were categorized as 13C2, and 4 patients were 13C3. Final follow-up assessment of outcomes included Broberg and Morrey radiologicalcriteria; Mayo Elbow Performance Score, disabilities of the Arm, Shoulder and Hand (DASH) OutcomeMeasure, score based on Jupiter criteria; and range of motion (ROM) values.Results: The mean carrying angle of operated elbows was 11.37. According to Broberg andMorrey radiological criteria, 14 patients, had radiologically normal elbow, 4 patients had mild change, 3patients had moderate change, and 3 patients had severe radiological change. Mean DASH score was21.91 , and mean Mayo rating was 83.37 . Jupiter criteria evaluation revealedexcellent results in 10 cases, good in 12, and fair results in 2. One patient with fair result had openfracture, and the other had previous hemiparesis in the same extremity. There was no instance ofnonunion observed at follow-up.Conclusion: Osteosynthesis with medial-dorsolateral plating is a safe and effective method for thetreatment of intra-articular fractures of distal humerus.Level of evidence: Level IV, Therapeutic study.© 2017 Turkish Association of Orthopaedics and Traumatology.
