Multiplane fracture of the distal humerus.

A unique but complex intraarticular fracture of the distal humerus is described. The term multiplane fracture has been applied to highlight a fracture pattern that features not only the well recognized T fracture lines in the sagittal and horizontal planes but also a coronal fracture of the trochlea. The Herbert screw was used in five cases to achieve stable fixation of the purely articular coronal fracture. At a follow-up of 20 months, on average, all fractures healed with an acceptable functional result. No radiographic evidence of avascular necrosis was seen in the follow-up radiographs.
