This protocol describes the use of 3D planning and printing for reconstruction of bony defects. We use segmentation tools to create 3D models followed by 3D design software to create patient specific implants for reconstruction purposes concomitant to ablative surgery or as a second stage.

Coronoid-Temporalis Pedicled Flap for Orbital Floor Defect Reconstruction
0 Views •
2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.

Although mouse models are invaluable tools for bone tissue engineering, models of long bone defects are sparse. This need motivated development of the present protocol which uses a locking plate with four screws and a dedicated jig to perform and stabilize a reproducible, femoral, critical-size defect with low morbidity.
FAQs
Osteoconduction provides a physical framework that allows new bone to form through the defect, whereas osteogenesis is supported by living graft cells that directly contribute to bone formation. Signaling factors can further encourage the regenerative process. Combining these biological functions may help the reconstructed area integrate with surrounding tissue rather than serving only as a passive filler.
Blood supply is a major determinant of whether reconstructed bone can heal and integrate with adjacent tissue. It supports the biological activity associated with new bone formation and helps the repair respond to the local environment. Consequently, the same graft, synthetic material, or scaffold may produce different outcomes depending on the vascular condition of the defect.
These options provide different combinations of structural support and biological activity. Grafts may supply living cells or signaling factors, while synthetic materials and engineered scaffolds primarily provide space-filling support and a framework for osteoconduction. The relevant choice therefore depends on the desired balance among new bone formation, tissue integration, defect characteristics, and mechanical requirements.
Approach selection is influenced by the defect’s size, the mechanical demands placed on the reconstructed region, local blood supply, and the patient’s overall health. These variables affect both the biological capacity for healing and the need for structural stability. Considering them together helps align the graft, material, or scaffold with the expected reconstruction challenge.
Medical applications include traumatic bone loss, defects remaining after tumor removal, infection-related damage, and complex fractures. Each situation can create a different combination of missing tissue, instability, and impaired function. Reconstruction is used to address these problems by supporting skeletal continuity and healing, with the specific strategy shaped by the defect and the patient’s condition.
Evaluation can focus on restoration of skeletal continuity, mechanical stability, bone healing, integration with surrounding tissue, and recovery of function or mobility. Outcomes are not determined solely by the implanted material; defect size, blood supply, mechanical demands, and overall health also influence results. These measures help describe whether reconstruction achieved both structural and functional goals.
