Various Dosages of BMP-2 for Management of Massive Bone Defect in Sprague Dawley Rat
Introduction: The use of BMP-2 plays an important role in the treatment of extensive bone defect. However, data about the optimal dosage of BMP-2 in the massive bone defect cases is rare. Material and Method: Twenty-five SD rats were randomly divided into a control group ofhydroxyapatite (HA) alone (Group I), HA+BMP-2 1µg/mL (Group II), HA+BMP-2 5 ug/mL (Group III), HA+BMP-2 10 µg/mL (Gro...

متن کاملPeriacetabular malignant bone tumors managed by massive allografts
Four patients with a primary malignant pelvic tumor adjacent to the acetabulum were managed with a wide en bloc resection including most of the hemipelvis. A hemipelvic allograft was used for reconstruction. The mean follow-up was 7 (5-11) years. Three allografts had healed and were roentgenographically normal. One graft fractured. There was no local recurrence or infection. SICOT Online Report...
متن کاملReconstruction of Traumatic Bone Defect With In Situ Implantation of Dropped Traumatic Segmental Bone Fragments.
This study was conducted to determine whether in situ implantation of a dropped traumatic segmental bone fragment is safe and whether the authors' method would reduce the incidence of infectious and related complications. The authors retrospectively reviewed 16 patients with open fractures, including 11 with Gustilo-Anderson type IIIA fractures and 5 with Gustilo-Anderson type IIIB fractures wh...
متن کاملTomographic imaging of fragmented cortical bone heteroimplant and methylmethacrylate in segmental bone defect of rabbit tibia.
PURPOSE To evaluate the performance of composites consisting of fragmented cortical bone heteroimplant in association with methylmethacrylate preserved in 98% glycerin, in segmental bone defect of rabbit tibia medial metaphysis. METHODS In this study were used twelve adult New Zealand rabbits, divided into three groups of four animals each: G30 (30 days), G60 (60 days) and G90 (90 days). The ...
