A 15-year-old male patient presents for a right knee series after sustaining a varus injury while playing football.AP, lateral, and both oblique radiographs of the knee demonstrate an avulsion fracture of the lateral tibial plateau (Segond fracture).What additional imaging modality would be best utilized in the diagnosis for this patient?

Question

Quizplus · Accepted Answer

MRI is the best imaging modality for further evaluation of Segond fractures as it can help detect associated ligamentous injuries, meniscal tears, and cartilage damage. CT may be useful in certain cases to evaluate fracture displacement or articular surface involvement, but it is not as sensitive as MRI in evaluating soft tissue injuries. Knee arthrography and nuclear medicine are not indicated for this type of injury.
