MANAGEMENT OF TIBIAL PLATEAU FRACTURE Capt Zaw Myo Han
Introduction Tibial Plateau fractures make up 1% of all fractures Up to 70%, are isolated to the lateral plateau
3 DR.SITHU
anatomy tibial plateau makes up the superior articular surface of the tibia separated medially and laterally by the intercondylar eminence and both surfaces are covered by articular cartilage 4 DR.SITHU
anatomy medial plateau is larger, concave and significantly stronger than the lateral plateau. lateral plateau is smaller, relatively convex and weaker than the medial aspect menisci provide some stability and congruence for articulation with the femoral condyles 5 DR.SITHU
anatomy M ajor ligamentous attachments (MCL, LCL-PLC, ACL, PCL) N eurovascular structures that important are the peroneal nerve laterally popliteal vessels and tibial nerve posteriorly 14-Dec-23
. (1) Force directed either medially ( valgus deformity, the classic ‘‘bumper fracture’’) or laterally ( varus deformity) (2) Axial compressive force, or (3) Combined Mechanism of injury

AO classification Type A extra-articular metaphyseal and epiphyseal fractures Type B Partial articular fractures, in these injures, part of the articular surface retains its continuity with the diaphysis Type C Complete articular fractures in which the articular surface has lost all connection to the diaphysis divides the fractures not only into types but also into groups and subgroups 18 fracture types classified into six groups

increasing from 2% for type I to 50% for type V, with an overall average of 15%, approximately that of classic dislocation of the knee DR.SITHU 26
Presentation/ physical examination 27 DR.SITHU
DR.SITHU 28 Medial plateau injuries are associated with neurovascular complications more frequently due to the increased force required to cause the injury One must also have a high suspicion for compartment syndrome and ligament injury and have high vigilence for open injuries
Imaging STANDARD RADIOGRAPHIC VIEWS standard AP and lateral views two oblique views 29 DR.SITHU
Traction Radiographs If surgical intervention is contemplated used in determining the efficacy of distraction techniques Traction films reveal whether a ligamentotaxis reduction is possible and also aid in planning surgical incisions 30 DR.SITHU
Stress Radiographs It sometimes aid decision to operate or to proceed with nonoperative management Instability with greater than 7 to 10 degrees of motion in the coronal plane is usually managed with surgery 31 DR.SITHU
COMPUTED TOMOGRAPHY SCANNING CT scan provides the surgeon with the cross-sectional anatomy of the fracture and the potential for sagittal or coronal reconstruction at any desired depth 32 DR.SITHU
Traction CT scanning gives the surgeon a much better indication of the effectiveness of distraction techniques 33 DR.SITHU
MRI superior for assessment of associated soft tissue injuries such as meniscal and ligamentous disruptions 34 DR.SITHU
ARTERIOGRAPHY considered whenever there is serious concern about the possibility of an arterial lesion An intimal tear may be present without a clinically detectable deficit During fracture surgery, such a lesion may lead to an occlusive thrombosis that jeopardizes the extremity 35 DR.SITHU
Goal of Treatment Restoration of articular congruity Axial alignment Joint stability Functional motion of knee joint 14-Dec-23
Non-operative Treatment Absolute indication Fractures that occur after a low-energy injury which are usually incomplete or non-displaced a displaced lateral plateau fracture without articular instability and some unstable lateral plateau fractures in osteoporotic patients Relative indication presence of significant cardiovascular, pulmonary, neurologic, or metabolic compromise 42 DR.SITHU
Operative Treatment 43 DR.SITHU
Timing of Surgery urgently irrigated & debrided repeated debridement Antibiotics Fasciotomy Immediate internal fixation & delayed closure Open fracture 44 DR.SITHU
Temporary spanning external fixator Initial treatment modality of choice Stabilizes the soft tissue Pain relief Fracture reduction via ligmentotaxis Visualizations of soft tissue Mobilization 45 DR.SITHU
In polytrauma patient and in those with soft tissue compromise, reduction of the joint is advocated as soon as possible Percutaneous or limited incision approaches with temporary spanning external fixation across the joint allows mobilization of the polytrauma patient 46 DR.SITHU
Preoperative Planning Routine and traction X-rays CT Scan and MRI Confirm that appropriate implants and reduction instruments. Use of preoperative drawings to make a detailed plan of all the steps in the surgical tactic. Surgery is performed on paper before being carried out in the operating room. 14-Dec-23

Four primary factors determine the prognosis 64 DR.SITHU
Post-operative Care To minimize complications and loss of reduction of the fracture and maximize knee motion A period of non-weight bearing or minimal weight bearing is necessary to minimize the chances of displacing the reduced fracture. Duration depends on the fracture pattern and the strength of the fixation Probably takes 6 to 12 weeks Early motion was much more important after operative treatment Immobilized for longer than 2 weeks tended to be stiff 14-Dec-23
Practice points All high- energy tibial plateau fractures have concomitant soft- tissue injury Temporary spanning external fixation is often the initial treatment of choice A biologic approach, mindful of the vascularity of soft tissue and bone, can prevent many adverse outcomes 66 DR.SITHU
Summary With more complex fractures, it is essential to consider not only the bone injury but also the associated soft tissue damage Use of limited open approaches ligamentotaxis , indirect reduction aids wire-guided cannulated screws minimally invasive plating techniques allows the surgeon to treat higher energy injuries effectively with internal fixation 67 DR.SITHU
