The cartilaginous primary physis, or growth plate, at the end of long bones in children allows for longitudinal bone growth. A variety of insults to the physis can lead to physeal bridge formation, which in turn can lead to limb-shortening and angular deformities. This paper begins with a description of the causes, risk factors and mechanisms by which bridges form. Then it reviews the use of imaging in the diagnosis and characterization of bridges and in the evaluation of treatment and post-treatment complications. It is important for radiologists taking care of children to be aware of the indirect and direct imaging findings of physeal bridges to aid in their diagnosis, to be able to characterize bridges as part of preoperative planning, and to know the imaging finding of post-resection complications.
儿童长骨末端的软骨性原发骺，即生长板，允许骨骼纵向生长。各种对骺板的损伤可导致骺板桥形成，进而导致肢体缩短和畸形。本文首先描述了桥形成的原因、危险因素和机制。然后回顾了影像学在诊断和评估桥的特征以及治疗和治疗后并发症中的应用。对于照顾儿童的放射科医生来说，了解骺板桥的间接和直接影像学表现以帮助诊断、能够对桥进行术前规划以及了解切除后并发症的影像学表现非常重要。
