Purpose Pectus arcuatum is an anterior chest wall deformity that requires transverse wedge sternotomy. Determining and delivering the correct cutting angle is crucial for successful correction. We present the early clinical experience with a novel cutting template technology able to deliver the optimal cutting angle. Description From patients’ computer tomography scans, the optimal cutting angle is obtained through computer aided design (CAD). A template comprising of slots tilted at the right cutting angle and safety block to avoid damaging the posterior periosteum is printed through additive manufacturing. Evaluation The template allows to perform a precise wedge sternotomy, safely sparing the posterior periosteum in all patients, without complications. Post-operative chest x-rays and pictures demonstrate optimal sternal realignment and cosmetic outcome. Mean operative time was 110 min. All patients were successfully discharged with a mean length of stay of 4 days. Conclusions Transverse wedge sternotomy aided by CAD-devised cutting template may reduce the technical challenge of this procedure, increasing its safety, reducing operative times and hospital stay. Further research on long-term patient outcome is necessary.

Abstract

Purpose Pectus arcuatum is an anterior chest wall deformity that requires transverse wedge sternotomy. Determining and delivering the correct cutting angle is crucial for successful correction. We present the early clinical experience with a novel cutting template technology able to deliver the optimal cutting angle. Description From patients’ computer tomography scans, the optimal cutting angle is obtained through computer aided design (CAD). A template comprising of slots tilted at the right cutting angle and safety block to avoid damaging the posterior periosteum is printed through additive manufacturing. Evaluation The template allows to perform a precise wedge sternotomy, safely sparing the posterior periosteum in all patients, without complications. Post-operative chest x-rays and pictures demonstrate optimal sternal realignment and cosmetic outcome. Mean operative time was 110 min. All patients were successfully discharged with a mean length of stay of 4 days. Conclusions Transverse wedge sternotomy aided by CAD-devised cutting template may reduce the technical challenge of this procedure, increasing its safety, reducing operative times and hospital stay. Further research on long-term patient outcome is necessary.
