- DH resembles a triangle, with the medial & lateral columns making up the sides and the trochlea forming the base
- Reconstruction of the premorbid anatomy of the trochlea is crucial to restoration of motion and stability
- AO and Riseborough & Radin’s Classification commonly used
- Lambotte, in the first decade of the 20th century, was one of the first to describe operative techniques for stable osteosynthesis of the distal humerus
- Problems with distal humerus fractures are : Highly constrained elbow joint, Narrow supracondylar isthmus, Sparsity of adequate subchondral metaphyseal supporting bone, Comminution, Osteoporosis
- Posterior approach : Triceps splitting, Triceps reflecting, Olecranon osteotomy
- TRAP approach- quicker to expose and repair, allows extensive distal humerus exposure, including the supracondylar/intercondylar region
