Abstract
Objective: To assess the functional outcome of humerus intercondylar fracture using Mayo elbow performance score.
Methodology: This study was conducted at Departments of Orthopaedics and Trauma, Khyber Teaching Hospital and Hayatabad Medical Complex, Peshawar, from January 2015 to December 2019. Patients who had distal humerus fracture of AO classes 13C1, 13C2 and 13C3 were included in the study. Patients with poly trauma, the extremes of age (<18 years > 65 years) and those with pre-existing pathologies were excluded from the study. Intraoperative, 4.5mm partially threaded cancellous screws were used to establish articular congruity. Reconstruction or distal humerus locking plates were applied in 90-90 fashion on both columns and tension band wiring for olecranon osteotomy. Functional outcome was assessed at six months using Mayo elbow performance score.
Results: Out of 43 patients, 19 were male and 24 female. Thirteen patients had 13C1 distal humerus fractures, 19 had 13C2 while 11 had 13C3 fractures. Mean Mayo score was 73.516.5. Three patients scored excellent, 9 scored good, 4 had fair and 3 poor results. We noted that 32% patients had no pain at 6 months, 42% had mild pain and 21% had moderate pain. Stability and function results were also satisfactory.
Conclusion: Based on this study, early open reduction and rigid internal fixation with plates in 90-90 fashion followed by early post-operative mobilization showed a good outcome in distal humeral intercondylar fractures.

Key words: Distal humerus, dual plating, trauma.
