Reports in the literature offer conflicting data on the value of the midsternal stripe sign in diagnosing sternal dehiscence. Our purpose was to determine the frequency with which the midsternal stripe sign is present in patients with dehiscence compared with a control group without this complication and to determine whether this sign adds incremental value to the sign of sternal wire displacement in the diagnosis of dehiscence.
A midsternal stripe thicker than 3 mm should raise one's suspicion of the presence of sternal dehiscence. However, this sign is rarely observed in patients with this complication and does not add incremental value to the finding of sternal wire displacement in establishing the diagnosis of dehiscence.
文献报道中关于胸骨中线征在诊断胸骨裂开方面的价值存在相互矛盾的数据。我们的目的是确定与无此并发症的对照组相比，胸骨裂开患者出现胸骨中线征的频率，并确定该体征在胸骨裂开诊断中对胸骨钢丝移位征是否具有额外的诊断价值。
胸骨中线宽度大于3mm应引起对胸骨裂开存在的怀疑。然而，该体征在患有此并发症的患者中很少观察到，并且在确立胸骨裂开诊断时，对胸骨钢丝移位这一发现不具有额外的诊断价值。
