Clincal value of different MRI sequences in the diagnosis of elbow trauma in children / 中国基层医药

ABSTRACT

Objective:To analyze the clinical value of different MRI sequences in the diagnosis of elbow trauma in children.Methods:From March 2015 to March 2019, 78 children with elbow joint injury were studied.All patients were examined by X-ray and MRI, including 3D-DESS, TSETIWI, T1-TIRM and FS-PDWI.The differences between the two methods were analyzed.Results:A total of 62 cases of epiphyseal fracture were confirmed by MRI.According to the distribution of Salter Harris fracture 23 cases of type Ⅱ (37.10%)>17 cases of type Ⅲ (27.42%)>12 cases of type Ⅳ (19.35%)>10 cases of type Ⅰ (16.13%)>0 case of type Ⅴ (0.00%), the difference was statistically significant (χ 2=6.126, P=0.025). Among 78 children of elbow joint injury, 73 cases had bone marrow edema, of which 62 cases were within 1 cm from epiphyseal plate, 11 cases were outside 1 cm from epiphyseal plate, 5 cases were without bone marrow edema, and there was a correlation between bone marrow edema and epiphyseal fracture ( r=0.174, P=0.006). Type Ⅰ-Ⅳ epiphysis injury of elbow joint in children could be accompanied with articular cartilage injury, and 3D-DESS had good effect on articular cartilage injury. Conclusion:Different sequences of MRI have high accuracy in the diagnosis of elbow joint injury in children, which is of great significance in reducing misdiagnosis and missed diagnosis rate of epiphyseal fracture, bone marrow edema and articular cartilage injury in children.
