目的：探讨MRI对膝关节骨挫伤的诊断价值，提高临床医师对骨挫伤诊断及鉴别诊断的认识。
方法：收集2008年5月至2009年12月经MRI检查确诊的膝关节骨挫伤47例进行回顾性分析，其中男30例，女17例；年龄12～69岁，平均34.5岁。47例外伤后局部均出现疼痛、压痛和(或)软组织肿胀及功能障碍，MRI检查时间自外伤后6 h～30 d，平均7 d。单纯骨挫伤临床采用保守及对症治疗。
结果：47例共显示82个病灶，其中股骨下端39个，胫骨上端(包括胫骨平台)35个，髌骨5个，腓骨上端3个。MRI表现为不规则斑片状或地图样T1WI低信号、T2WI等或略高信号，STIR脂肪抑制序列均呈明显高信号，其中伴半月板撕裂20例，侧副韧带损伤14例，前交叉韧带损伤8例。47例X线、CT检查未见骨折征象。经治疗后临床症状和体征均明显减轻或消失，29例获随访，时间1～12个月，MRI异常信号消失21例，异常信号减弱8例。
结论：MRI能揭示膝部骨挫伤的病理改变，并准确判断关节周围韧带及软组织的损伤情况，常规MRI检查并行脂肪抑制序列是诊断外伤性骨挫伤最有价值的方法。 |

Abstract:
Objective: To investigate the MRI diagnosis of bone contusion on the knee,and improve the diagnosis skill.
Methods: A retrospective analysis of 47 cases of knee bone bruise with the performance of MRI in our hospital from 2008.5 to 2009.12,including 30 males and 17 females,aged from 12 to 69 years,with a mean of 34.5 years old. Forty-seven patients suffered from post-traumatic localized pain,tenderness and(or) soft tissue swelling and dysfunction. The time interval between the accident and the MRI examination ranged from 6 h to 30 days,averaged 7 days. The patients with only bone contusion were treated with conservative and symptomatic treatment.
Results: A total of 47 cases showed 82 lesions,including 39 distal femur,35 proximal tibias(including the tibial plateau),5 patellas,3 fibula top. MRI showed irregular patchy or map-like T1WI low signal,isointensity or slightly high signal intensity T2WI,STIR fat suppression all showed obviously high signal,in which 20 patients with torn meniscus,collateral ligament injuries in 14 cases,anterior cruciate ligament injuries in 8 cases. The X-ray and CT examination of all the patients revealed no signs of fracture. The clinical symptoms and signs of all the patients significantly reduced or disappeared after treatment. Among 29 patients who were followed up from 1 to 12 months,21 patients had abnormal MRI signal disappearing and 8 patients had abnormal signal weakened.
Conclusion: MRI can reveal pathological changes of bone contusion on the knee,and accurately determine ligaments around the joint and soft tissues injuries. Conventional MRI examination and fat-suppression sequence is the most valuable method of bone contusion. |
