Can CT Findings Predict Ligament Tear or Meniscal Injury?
Mui L.*; Engelsohn E.; Umans H.; Radiology, Jacobi Medical Center, Bronx, NY. Address correspondence to L. Mui (leowmui{at}yahoo.com’ + u + ‘@’ + d + ”//–>) Objective: To compare CT and MRI data in patients with acute tibial plateau fracture to determine 1) CT criteria which might predict ligamentous injury and 2) assess if CT findings correlate with meniscal injury as identified by MRI. Materials and Methods: We reviewed all imaging and surgical data for patients presenting to our institution from 12/01-8/05 with acute tibial plateau fracture in whom CT and MRI were obtained pre-operatively (n = 41). MRI and CT images were separately analyzed for: Schatzker classification, intercondylar eminence fracture or fibular avulsion, maximal articular gapping and depression. CT images were reviewed, blinded to MRI data, to determine if ligament tear could be detected. Insertion site avulsions were deemed indicative of intact corresponding ligaments.
