Curvilinear distraction is currently under investigation to reconstruct curved maxillofacial bone defects. However, previous studies have revealed the discrepancy between the contour of the regenerated bone in the distraction gap and the curvilinear pathway of the transport disc. We hypothesize that the discrepancy is because of the conflict of the distraction vector and the strain vector during the consolidation. In curvilinear distraction osteogenesis, the distraction vector varies, while the strain vector during the consolidation phase is fixed-linear, from the beginning to the end of the distraction pathway. Here we bring forward a solution of segmental curvilinear distraction osteogenesis to divide the curvilinear distraction into several segments, with respective consolidation for each distraction gap. If this hypothesis is verified, the segmental distraction curvilinear distraction will benefit the reconstruction of complicated long-range maxillofacial bone defects.
