Innovative surgical repair of severe pectus carinatum using 3D surgical planning and advanced rib fixation techniques.

This case describes an early adolescent boy with severe pectus carinatum, managed with a complex surgical approach after bracing was deemed unfeasible. A multidisciplinary team collaborated, using advanced three-dimensional (3D) imaging, digital segmentation and a patient-specific 3D-printed model to plan and rehearse the surgery. The operation involved sternum repositioning and rib plating with polyether ether ketone plates. The procedure resulted in favourable chest stability and minimal blood loss. Postoperatively, the patient's pain was well-controlled, and he was discharged on day 7. The patient expressed satisfaction with the outcome and resumed normal activities within a month.
