为了评估MRI是否可用于评估创伤后生长板软骨的异常，对26例骨骺骨折的28例患者在伤后4天至2年进行了MRI检查。12例患者在骨折后6个月内接受了研究。6例MRI改变了Salter-Harris分级。在T2加权像上检测到的生长板中断与随后的8例患者中的6例生长异常相关。4例患者中只有1例生长发育障碍与生长发育不全相关。损伤后6个月后，对16个生长板进行了研究。12例有骨骺板和异常生长。在4例MRI检查无骨骺异常的患者中，2例生长正常，2例轻度畸形。我们的研究结果表明，磁共振成像缺陷与随后的生长障碍相关的软骨异常，并提供了准确的映射骨骺桥和相关的生长异常，已经发生。
In order to assess whether MR imaging could be used to evaluate posttraumatic abnormalities of the growth plate cartilage, 28 MR imaging examinations of 26 physeal fractures were performed from 4 days to 2 years after injury. Twelve patients were studied within 6 months of the fracture. MR imaging changed the Salter-Harris classification in six. Interruption of the growth plate detected on T2-weighted images was associated with subsequent growth anomaly in six of eight patients. Horizontal fracture of the physis without interruption was associated with growth disturbance in only one of four patients. Sixteen growth plates were studied beyond 6 months after injury. Twelve had physeal bars and abnormal growth. Of four patients without physeal abnormality on MR imaging, two had normal growth and two had mild deformity. Our results show that MR imaging defects abnormalities in the cartilage that are associated with subsequent growth disturbances and provides accurate mapping of physeal bridging and associated growth abnormalities that have already occurred.
