The early results of massive osteoarticular allograft in the surgical treatment of lower limb bone tumors
This is the early results of 20 cases of massive osteoarticular allograft performed for reconstruction of lower limb s after resection of bone tumors. These cases include 7 distal femur and hemiarticular ,6 proximal tibio and hemiarticular, 3 total knee joints and 4 proximal femur with total hip replacement. Bone allografts were taken at steril condition from early postmortum cadavers and st...
متن کاملSystemic zoledronate treatment both prevents resorption of allograft bone and increases the retention of new formed bone during revascularization and remodelling. A bone chamber study in rats
BACKGROUND In osteonecrosis the vascular supply of the bone is interrupted and the living cells die. The inorganic mineral network remains intact until ingrowing blood vessels invade the graft. Accompanying osteoclasts start to resorb the bone trabeculae and gradually replace the bone. If the osteonecrosis occurs in mechanically loaded parts, like in the subchondral bone of a loaded joint, the ...
متن کاملEvaluation of Clinical Results and Complications of Structural Allograft Reconstruction after Bone Tumor Surgery
Background: Massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. The purpose of this study was to analyze the outcome of these procedures at Imam Reza Hospital, Mashhad University of Medical Sciences. Methods: In this study, 113 cases have been presented. Eleven cases were excluded (patients has a traumat...
متن کاملThe effect of freeze-dried bone allograft and partially demineralized freeze-dried bone allograft on regeneration of rabbit calvarial bone defects: A Histological and histomorphometric study
Background and Aims: Reconstruction of osseous defects is one of the ideal goals of periodontal treatments and dental implant therapy. Different biomaterials have been used for this purpose and many studies have tried to compare and introduce the best ones. The present study aimed to evaluate the effect of PDFDB (Partially Demineralized Freeze-Dried Bone Graft) and FDBA (Freeze Dried Bone Allog...
متن کاملThree-Dimensional Virtual Bone Bank System Workflow for Structural Bone Allograft Selection: A Technical Report
Structural bone allograft has been used in bone defect reconstruction during the last fifty years with acceptable results. However, allograft selection methods were based on 2-dimensional templates using X-rays. Thanks to preoperative planning platforms, three-dimensional (3D) CT-derived bone models were used to define size and shape comparison between host and donor. The purpose of this study ...
