To identify the incidence of hardware and bone-healing complications in patients who underwent locking mandibular reconstruction plate (LMRP) fixation of vascularized bone grafts for reconstruction of segmental mandibular defects.Design: Case series.Setting: Academic tertiary care medical center.Patients: One hundred one patients who had undergone LMRP fixation of vascularized bone grafts for reconstruction of segmental mandibular defects with a minimum follow-up of 6 months.Main Outcome Measures: Association of patient-and defect-related characteristics with the incidence of loose screws, osteosynthesis nonunion, and complications necessitating hardware removal. Results:The incidence of loose screws was 0.8% in 984 locking screws implanted. The incidence of nonunion was 0.7% in 290 osteosyntheses. Overall, 15 of 101 LMRPs

To test the mechanical properties of regenerate cortical bone created using Mandibular Bone Transport (MBT) distraction, five adult male American foxhound dogs underwent unilateral distraction of the mandible with a novel MBT device placed to linearly repair a 30-35 mm bone defect. The animals were sacrificed 12 weeks after the beginning of the consolidation period. Fourteen cylindrical specimens were taken from the inner (lingual) and outer (buccal) plates of the reconstructed mandible and 21 control specimens were removed from the contralateral aspect of the mandible. The mechanical properties of the 35 cylindrical cortical bone specimens were assessed by using a non-destructive pulse ultrasound technique. Results showed that all of the cortical mechanical properties exhibit higher numerical values on the control side than the MBT regenerate side. In addition, both densities and the elastic moduli in the direction of maximum stiffness of the regenerate cortical bone specimens are higher on the lingual side than the buccal side. Interestingly, there is no statistical difference between elastic modulus (E 1 and E 2 ) in orthogonal directions throughout the 35 cortical specimens. The data suggest that the regenerate canine cortical bone is not only heterogeneous, but the elastic mechanical properties tend to approximate transverse isotropy at a tissue level as opposed to control cortical bone that is orthotropic. In addition, the elastic mechanical properties are not only higher on the control side but also in the lingual anatomical position, suggesting a stress shielding effect from the presence of the reconstruction plate.
