Final answer:
Tibial widening after ORIF of a plateau fracture refers to the separation or widening of the tibial plateau. The amount of acceptable widening without adversely affecting outcomes can vary depending on several factors, including the type of fracture, patient characteristics, and the specific goals of treatment. Some studies suggest that tibial widening of up to 5mm may be acceptable without adversely affecting clinical outcomes.
Step-by-step explanation:
Tibial widening after open reduction and internal fixation (ORIF) of a plateau fracture refers to the separation or widening of the tibial plateau. This can occur due to factors such as malalignment, loss of reduction, or failure of fixation. The amount of acceptable widening without adversely affecting outcomes can vary depending on several factors, including the type of fracture, patient characteristics, and the specific goals of treatment.
There is no specific universally accepted threshold for tibial widening after ORIF of a plateau fracture. Some studies suggest that tibial widening of up to 5mm may be acceptable without adversely affecting clinical outcomes, while others consider more than 2mm of widening to be significant. It is important to note that the clinical significance of tibial widening should be assessed in conjunction with other factors, such as joint congruity, alignment, and functional outcomes.
The impact of tibial widening on outcomes can be influenced by various factors. These include the presence of concomitant ligamentous injuries, the severity and pattern of the fracture, the accuracy of reduction and fixation, and the overall stability of the knee joint. Additionally, individual patient characteristics, such as age, activity level, and comorbidities, may also affect outcomes.
