Abstract
Objective:To investigate the value of MRI in the diagnosis of bone contusion of the knee joint and ankle joint. Methods: A retrospective analysis of 65 cases of knee and ankle bone bruise whith the performance of MRI in our hospital from 2010.6 to 2012.4, including 40 males and 25 females, aged from 10 to 65 years, in averaged of 32 years old. 65 patients suffered from posttraumatic localized pain, soft swelling and dysfunction. The time interval between the accident and the MRI examination ranged from 6 h to 25 days, in averaged of 10 days.The patients with only bone contusion were treated with conservative and symptomatic treatment. Results:A total of 125 lesions in 65 cases, including 52 distal femur, 48 tibial plateau, 5 patella, 10 fibula, 2 astragalus;MRI showed irregular patchy or map-like in T1WI low signal and T2WI etc or slightly higher than the signal shadow and STIR fat suppression sequence is obvious hyperintensity. Associated with meniscal tears in 15 cases, anterior cruciate ligament injury in 11 cases. Conclusion: MRI can reveal pathological changes of the bone bruise and determine ligaments around the joint and soft tissue injury. conventional MRI examination in parallel fat-suppression sequence is the diagnosis of traumatic bone contusion of the most valuable method.关键词
