AOT Advanced Principles Course
Principles for soft-tissue management
• Wait for the soft tissue!!
• Staged treatment if ORIF of tibial plateau
fracture
Principles for definitive fixation
• Fully understand the fracture,
especially the 3-D construct
• Anatomically restore the
articular surface—no structural
articular defect
• Stable fixation to maintain the
alignment
3-Column-concept. Luo CF, Sun H, Zhang B, et al. Three-column fixation for complex tibial plateau fractures. J Orthop Trauma. 2010 Nov;24(11):683-92.
3-Column classification
• Column fracture—breakage of
corresponding cortex
(compression/tension fracture)
• Localize the articular surface
depression
• Pure depression of articular
surface (Schatzker type III)—
“zero column fracture”
Principles for approach selection
• Biomechanics of fixation
• Depressed articular
fragment
• Soft-tissue tolerance
Principle for plate fixation
• Buttress fixation is preferred for
column fractures
• Main buttress plate is chosen
according to the injury
mechanism
• Bridging is used for comminuted
metaphyseal fractures
2 column fractures
• Understanding the fracture is essential for decision making and definitive fixation
• If not too comminuted combination ORIF surgery with 2 plates and 2 approaches are possible
Bone graft
• Often needed for
articular defect
• Grafting technique
can reduce the
amount of bone graft
• Bone substitute can
be considered
The result of ORIF for this type of injury is not satisfactory Papagelopoulos PJ, Partsinevelos AA, Themistocleous GS et al. Complications after tibia plateau fracture surgery. Injury. 2006 Jun;37(6):475–484.

Take-home messages
• Fully understanding the fracture is essential for decision making and definitive fixation
• Approach selection and fixation should take into account the soft tissue, mechanism of injury, and 3-D morphology
• 3-column classification provides a way of planning the treatment of tibial plateau fractures
• ORIF and EX-fix supplements each other
