Resection of the manubrium including both sternoclavicular joints is occasionally performed in the case of sternal tumours. Sternoclavicular joints are the only true joints connecting the axial skeleton to the upper extremity. Therefore, they play an important role in shoulder function. However, data on their reconstruction are lacking. Here, we described the case of a sternal reconstruction including both sternoclavicular joints using a mesh-bone cement sandwich. The mechanical properties of the construct mimicked those of the original sternoclavicular joints and could therefore restore shoulder strength allowing the patient to perform overhead work.
