Background: Intra articular fractures of the distal humerus are uncommon injuries and present the most difcult challenge among fractures of the distal end of the humerus. Objective of this study is to evaluate the functional outcome following bicolumnar plating of AO-Type 13C distal humerus fractures. A total of 20 int Materials and Methods: ra articular (AO TYPE C) distal humerus fractures were operated within a period of 2 years in KVG medical college and hospital Sullia were included in the study in which there were 12 males and 8 females.16 cases were due to RTA, 4 were due to self-fall, Out of 20 cases,1 (5%) was of AO C1 type of fracture, 16(80%) were of C2 and 3 (15%) were of C3 type of fractures. All the patients were operated with pre-countered distal humerus locking plates in orthogonal fashion and functional outcome was measured by Mayo's Elbow Performance Score (MEPS). In our series of 20 cases, the Results: average duration of the radiological union was 16±02 weeks. Excellent results were seen in 10, good in 6 and fair in 3, and poor in 1 According to Mayo's Elbow Performance Score (MEPS) at the end of 12 months follow up. Open reduct Conclusion: ion and internal xation with bicolumnar plating is the ideal xation for AO 13 type C distal humerus fractures. Use of locking plates, stable xation, along with early elbow mobilization inuence the nal functional outcome. Bicolumnar plating provides better stability, allows early elbow range of motion and prevents elbow stiffness.
