PURPOSE: This study was aimed at analyzing the incidence and characteristics of hyperextension tibial plateau fractures (HTPFs) by using a computed tomography (CT)-based "four-column and nine-segment" classification. METHODS: In the coronal plane, HTPFs are divided into four types: pure hyperextension, hyperextension-varus, hyperextension-valgus, and hyperextension-bicondylar. Fractures in the sagittal plane were divided into three types: type 1, pure depression; type 2, cleavage extending to the posterior cortex with no displacement; and type 3, cleavage extending to the posterior cortex with a significant displacement. A retrospective analysis of CT images of the tibial plateau fractures from December 2007 to December 2021 was conducted. Fracture mapping was analyzed and drawn using the new classification system. RESULTS: A total of 136 (10.9%, 136/1253) fractures fulfilled the radiographic criteria for HTPF pattern in 136 knees (53.5 ± 13.3 years). There were 11 knees with pure hyperextension fracture (8.1%), 23 with hyperextension-varus fracture (16.9%), 46 with hyperextension-valgus fracture (33.8%), and 56 with hyperextension-bicondylar fracture (41.2%) in the coronal plane. Furthermore, there were 64 (47.1%), 47 (34.6%), and 25 (18.4%) cases of type 1, type 2, and type 3 fractures, respectively, in the sagittal plane. In the three-dimensional heat map, the fracture lines were mainly located at the anterior rim of the tibial plateau, while the posterior articular surface was rarely involved. CONCLUSIONS: The main manifestations of HTPF are anterior compression and posterior avulsion injury. The CT-based four-column and nine-segment classification system could be used to categorize the injury characteristics of HTPF in the coronal and sagittal planes.
