Objective To explore the shape and structure of calcified cartilage zone and its interface between the non-calcified articular cartilage and subchondral bone plate.
目的探索关节软骨钙化层的结构形态及其与软骨非钙化层和软骨下骨之间的界面连接方式。
CT findings included interruption of calcified costal cartilage with obvious malposition in 15 cases, and focal high-density of calcified costal cartilage were discontinuous in 5 cases.
CT表现特征包括肋软骨钙化中断伴断端明显错位（ 15例）和肋软骨条状略高密度影不连续伴断端明显错位（ 5例）。
Conclusion: Spiral ct associated with MIP and 3d-ssd reconstruction have important clinical value in the diagnosis of traumatic fracture of non-calcified costal cartilage.
结论：应用螺旋CT扫描、MIP及3d - SSD对未钙化肋软骨骨折的诊断有着重要临床价值。
