Objective. The purpose of tbis study was to demonstrate the MBI findings associated with acute tibial plateam -.
Materials and Methods. MB scans of 29 patients with acute tibial plateau fractures were analyzed rewpethely. The images were evahated for the presnce of injurks involving tbe meaiaci, cntchte rud collateral ligameab. The presema of a lipokoartbrosis or a simple joint effusion was also noted. The t3bial plateau fkactures were ttIad&d acxdlng to the scheme devised by schalzker.
Retadts, Evidence ofintemal derangement of the knee was fouud in 28 (97%) patients. Tibial colhteral t (55%) injudes and lateral meniscus (45%) tears were noted most frequently. Medial lnenkustearswerasesnln 21% and fib&r coliatend ligament injuries were diagnosed in 34%. Forty-one percent had anterior cxuchte ligament ir@les while the posterhr cruciate ligamest was injored in 28%. Twelve (41%) patknts c+mmeWde MIU features of a lipobemarthrosis. Simple joint effusions were found in the remaining 17 (96 patients.
Cohksion. MB imaging in patients with acute tibial plateau fracture3 commonly demot3stmes associated Iigrunento~s and mmiscal lnjurks. By imaging in multiple plpoes, MBI can aid in the accurate &ra&erhtioo of tibial plateau fracture patterns and severity.
