Posterior/lateral complex fractures of the tibial plateau are not uncommon clinically and are often due to high-energy injuries, the complexity of which has long been recognized and more difficult to treat [1]. Traditional surgical approaches include anterolateral, posterior medial and posterior surgical approaches, with varying operative times and clinical outcomes. From August 2010 to March 2012, 16 cases of posterior and lateral complex fractures of the tibial plateau were treated by the lateral enlarged incision approach and achieved better results, which are reported as follows: Fan Shicai, Department of Traumatology, Third Affiliated Hospital of Southern Medical University Data and methods I General data The group of 16 cases, 12 male and 4 female; age 21-66 years, mean age 37.9 years; left side 5 cases, right side 11 cases; cause of injury All 16 cases were closed fractures, and according to CT triple column typing [2], they were all collapsed fractures affecting the lateral column and posterior lateral column, combined with medial column fractures in 6 cases and fibular head fractures in 12 cases. The time between injury and surgery ranged from 6 d to 15 d, with an average of 9 d. Only patients with complex fractures involving the posterior/lateral tibial tuberosity were included in this group, and all were operated through an enlarged lateral knee incision.
