Purpose To evaluate the diagnostic value of MRI in bony bridge formation of posttraumatic growth plate.

目的研究MRI对长骨生长板创伤后骨桥形成的诊断价值。

An "interbody fusion" is a bony bridge that "welds" the two vertebral bodies together to stop unstable motion.

“椎体融合术”就是将两个脊椎连接起来防止脊椎不稳定的手术。

Results: the direct physeal injury could cause bony bridge formation and the premature closure of growth plate.

结果：骺板直接损伤可导致骨桥形成，骨骺提前闭合。

The articular discs were found displaced in all cases and early bony bridge formed at a limited area where there was no disc as cushion.

术中探及的关节盘全部发生移位，早期强直骨化发生在无关节盘区域。

Noncartilaginous tissue and material could only prevent formation of bony bridge in small defect of growth plate and lacked ability of regenerative repair.

非软骨组织材料只能阻止小面积生长板缺损内骨桥形成，无再生修复能力。
