Purpose: To review available approaches and fixation methods for posterolateral fracture fragment (PLF) in tibial plateau fracture, and to propose an algorithm to treat various types of plateau fractures which all involve the PLF.
Methods: This article reviews multiple surgical approaches for PLF and suggests an algorithm for suitable approach and fixation method according to PLF with combined plateau fracture.
Results: The modified anterolateral approach is a suitable single approach for fractures with a PLF combined with an anterolateral plateau fracture and for isolated posterolateral fracture fragments. For a multicolumn tibia plateau fracture involving the lateral, medial and posterior columns, dual approaches (modified anterolateral and posteromedial approach) can be used to access the entire plateau area.
Conclusions: When considering approaches of this complex fracture pattern, one must consider local soft tissue condition, plateau fracture morphology, associated injuries, and fixation options. After review of multiple approaches described in the literature for PLF fixation, we can suggest an algorithm for the approach and fixation to treat tibial plateau fractures with posterolateral fracture fragments.
