Abstract：
Anterior chest wall instability as a result of sternocostal non-union is a rare complication but can give rise to invalidating pain and cardiac arrhythmias. A woman in her 40s was referred to us with anterior chest wall pain and instability after a modified Ravitch procedure. Sternocostal pseudoarthrosis was seen for which multiple operations were performed which were complicated by low-grade infections. A patient-specific three-dimensional modelled and printed prostheses was used in an operation to both lift the sternum for pectus correction and to reconnect the sternum and the sternal costal junction to regain anterior chest wall stability.
摘要：
胸肋不愈合导致的前胸壁不稳定是一种罕见的并发症，但可引起无效的疼痛和心律失常。经过改良的Ravitch手术后，一名40多岁的妇女因前胸壁疼痛和不稳定而被转诊给我们。观察到胸肋假性关节病，其中进行了多次手术，并伴有低度感染。在手术中使用了针对患者的三维建模和打印假体，既可以抬起胸骨进行胸肌矫正，又可以重新连接胸骨和胸骨肋部，以恢复前胸壁的稳定性。
