Sternectomy Reconstruction Using a Customized Three-Dimensional-Printed Polyetheretherketone Implant.

Complex sternal and chest wall reconstruction can be a challenging clinical situation, with the main objectives being restoration of chest wall rigidity, protection of intrathoracic organs, preservation of respiratory function, and reduction of pain and clicking. The treatment of choice is varied, with several different materials available to aid in adequate reconstruction. We present the case of a 60-year-old male with a post-sternectomy defect and debilitating symptoms who underwent reconstruction with a customized, three-dimensional (3D)-printed polyetheretherketone (PEEK) implant and pectoralis muscle flaps. There were no complications in the perioperative period, and the patient reported significant improvement in pain and subjective improvement in chest stability and respiration. The use of PEEK as a reconstructive material for cardiothoracic defects is a viable and safe method that has several important benefits over other utilized materials in the literature. The early success of this case in relieving patient symptoms opens the door for further exploration of PEEK as an alternative for cardiothoracic reconstruction.
