Integrating the Masquelet Technique and Bone Transport for Massive Tibial Defect: A Case Report Utilizing A Novel Approach Combining Concurrent Bone Transport , Masquelet Technique and 3D-Printed Bioresorbable Scaffold

Management of critical-sized bone defects constitutes a considerable clinical challenge. This report elucidates a hybrid approach for salvaging a limb with an 11 cm post-traumatic tibial defect. Given the patient's underlying schizophrenia, the primary objective of the reconstruction was to minimize the duration of external fixation. To mitigate this, we employed a strategy combining concurrent Ilizarov bone transport with the masquelet technique. The reconstruction was subsequently completed using a custom Osteopore 3D-printed scaffold meticulously designed to restore the patient's anatomy with high precision by utilizing a mirror image of the CT scan of the contralateral tibia. This design facilitated the restoration of length, alignment, and rotation and incorporated a central cavity to accommodate the intramedullary nail. This report delineates an effective, patient-centric combination of techniques to achieve anatomical restoration while reducing the treatment time.
