How are distal humerus fractures classified?

According to the anatomic location and fracture pattern:
Extra-articular
Epicondylar: fracture of the medial or lateral epicondyle
Supracondylar: fracture line above the epicondyles
Intra-articular
Transcondylar: fracture plane within the joint capsule; either lateral or medial condyle fractured
Intercondylar (bicondylar): an intra-articular fracture line splitting the medial and lateral condyles
