Sternal retraction can cause the first rib to be fractured posteriorly, injuring the brachial plexus. The authors conducted bone scans of 24 consecutive open-heart surgery patients and found an unexpectedly high number of rib fractures which in all but one case had not been seen on the chest radiograph. Bone scans are recommended whenever there is unexplained non-incisional pain in a patient who has undergone sternal retraction.
胸骨后缩可导致第一肋骨后部骨折，损伤臂丛神经。作者对连续24例心脏直视手术患者进行了骨扫描，发现肋骨骨折数量出乎意料地高，除1例外，所有骨折在胸部X光片上均未显示。对于接受过胸骨后缩手术且有无法解释的非切口疼痛的患者，建议进行骨扫描。
