Background: Supracondylar and Intercondylar in fractures of distal humerus are one of the common and complex fractures encountered in trauma care with a challenging management in terms of surgical approach as well as attainment of acceptable congruity of joint for proper elbow joint function. The aim of the study was to access the outcome of bicolumnar supracondylar and intercondylar fractures of distal humerus managed by orthogonal plating. Materials and method: This study was carried out under the Department of Orthopaedics, S.R.G. Hospital and Jhalawar Medical College, Jhalawar (Rajasthan). The study comprised of 15 patients 11 males and 4 females (fracture type, c1 - 9 cases, c2 - 4 cases, c3 - 2 cases) of supra and intercondylar fracture of distal humerus treated by orthogonal plating of both medial and lateral column of supracondylar humerus with olecranon osteotomy. all cases intra operative range of the motion was 100%, with appreciable stable fixation. Results: Results were analysed by mayo elbow performance index (MPEI) and Out of 15 patients 9 had excellent outcome, 5 patients had good outcome, 1 case fair results were obtained due to poor bone stock and compliance.

Conclusion: The posterior trans-olecranon approach gives excellent exposure of the distal articular surface of the humerus. Use of bicolumnar orthogonal plating is found to be successful method in obtaining the desired results if performed with expertise.
