To evaluate the radiologic and clinical results of treatment of the Shatzker type 6 tibia plateau fracture using the lateral and posteromedial dual incision approach and dual plating.

Twelve cases in eleven patients of Shatzker type 6 tibia plateau fracture which has been treated using the lateral and posteromedial dual incision approach and dual plating were analyzed with an average follow-up of 16 months. Times to union, alignment and reduction loss on radiograph and postoperative clinical outcome with checking the range of motion of the knee joint, Knee Society Score and UCLA activity scale were analyzed and evaluated.

In all cases, bony union was obtained in an average fifteen weeks after the operation, and there was no reduction loss. The arc of motion of the knee joint at the latest follow-up was 132 degrees on average. Average of Knee Society Score was 85 and UCLA activity scale was decreased from 9.6 points preoperatively to 5.7 points postoperatively.

The treatment of Shatzker type 6 tibia plateau fracture using the lateral and posteromedial dual approach and dual plating have shown clinically preferable results of excellent recovery of joint motion and good knee society score by early range of motion exercise after firm fixation. However, it was high energy injury, so the sports activity of patients was significantly decreased.
