Fig. 4From: Potential problem and solution of lateral plate postposition for the posterolateral tibial plateau fractureA schematic illustration depicting the procedure for measuring lateral tibial plateau posterior slope angle and the lateral tibial plateau angle is provided. A LPSA, stands for the angle formed between the line of the articular surface of the tibial plateau and the vertical line of the tibial shaft. B LTPA, defined as the lateral pinch angle formed between the axis of the tibia and the line connecting the medial and lateral plateauBack to article page
