Fibular Neck Osteotomy Approach in Treatment of Posterolateral Tibial Plateau Fractures: A Retrospective Case Series.

Med Sci Monit 2020 Nov 5;26:e927370. Epub 2020 Nov 5.

Department of Orthopedics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China (mainland).

BACKGROUND The surgical strategies for posterolateral tibial plateau fractures are still inconsistent. Although a number of operative approaches were previously reported for surgical treatment of fractures of the posterolateral column in the tibial plateau, some approaches fail to provide direct visualization of the articular surface and do not allow enough space to access the posterolateral area of the lateral tibial plateau, thereby leading to unsatisfactory reconstruction of the knee and poor articular activity. MATERIAL AND METHODS We retrospectively reviewed records of 21 patients who underwent fibular neck osteotomy approach for posterolateral fractures. Read More
