Study of intercondylar fractures of the distal humerus treated with 90-90 plating

Abstract

Intra articular fractures of the distal humerus cause considerable morbidity to the patients. There are several controversies regarding the approach and fixation of the fracture. AO advocated 90-90 plating of both columns while recent biomechanical studies demonstrated superior mechanical strength with parallel plating. But parallel plating is associated with many complications. We performed bicolumnar perpendicular plating in 15 intraarticular AO type C fractures through transolecranon approach. Ulnar nerve was isolated and carefully protected, but ulnar nerve transposition was not done. We achieved union in all cases with functional range of movement in 13 patients. We had no case of post-operatively developed ulnar nerve neuropathy or heterotopic ossification. The average Mayo Elbow Performance Score was 85 points. We infer that 90-90 plating is effective in intercondylar fractures of distal humerus with minimal complications.
