Periosteum Fracture Bone Strength THE MECHANICAL ROLE OF THE PERIOSTEUM ON THE IMPACT RESISTANCE OF BONE
Introduction: The role of periosteum in the blood supply of bones has been investigated by several investigators [5]. Its osteogenic potential, particularly its important role in fracture repair, is also well recognized [1, 3]. However, the biomechanical role of periosteum in the fracture behavior of bones has not been studied in detail. Although the periosteum is expected to be resistant to te...
متن کاملRegeneration of Periosteum in Denuded Bone
Fig. 1. Schematic of one-stage bone-transport procedure (yellow – bone, red – periosteum). A portion of diaphyseal bone is denuded of periosteum, osteotomized, and transported over an intramedullary nail to the site of the 2.54-cm critical-sized defect, where it is docked to the distal femur. The periosteal sheath is left in situ to surround the new defect site, leading to full infilling of the...
متن کاملEffective bone engineering with periosteum-derived cells.
Bone augmentation via tissue engineering has generated significant interest. We hypothesized that periosteum-derived cells could be used in place of bone marrow stromal cells (which are widely used) in bone engineering, but the differences in osteogenic potential between these 2 cell types are unclear. Here, we compared the osteogenic potential of these cells, and investigated the optimal osteo...
متن کاملPercutaneous screw fixation without bone grafting of scaphoid non-union.
BACKGROUND Delays in diagnosis and inadequate treatment of acute scaphoid fractures can lead to non-unions, presenting surgeons with unique challenges regarding optimal management. OBJECTIVES To evaluate the clinical and radiographic outcome of scaphoid non-unions treated with percutaneous screw fixation. METHODS The study group comprised 12 patients with scaphoid non-unions of an average d...
متن کاملImplant treatment without bone grafting in severely resorbed edentulous maxillae.
PURPOSE This article describes the surgical technique for implant treatment in severely resorbed edentulous maxillae without any alveolar reconstruction before or combined with implant placement. PATIENTS AND MATERIAL Fifteen patients with severely resorbed edentulous maxillae were treated with osseointegrated implants and fixed dental prostheses. All patients were initially considered to be ...
