periosteal ganglion cyst is a rare condition that can easily be misdiagnosed as other types of surface bony lesions because of cortical erosion and suggestive periosteal reactions on plain radiography. We encountered a periosteal ganglion located over the anterolateral aspect of the metaphysis of the distal tibia, which was connected to an intraosseous ganglion cyst through a cortical defect on...

INTRODUCTION: One goal of reducing fracture risk is to maintain bone stiffness and strength with aging despite a net loss in bone mass. It is well recognized that age-related bone loss is often accompanied by continued periosteal apposition [1]. Because variation in the amount of periosteal expansion may be a major contributor to fracture risk [2], having a better understanding of the factors c...

INTRODUCTION The periosteum may have an important function of new bone formation because of the abundant blood supply and the presence of osteoprogenitor cells. Periosteal cells have also been used for bone and cartilage formation. Though there have been many studies about the osteogenesis using periosteum, and osteogenic activity of osteoprogenitor cells such as mesenchymal stem cells(MSCs), l...

the purpose of this study is determining of some immunity and blood serum parameters in brood stock and grower fish before and after of stripping to evaluate the effect of breeding physiological changes on immunity and serum indexes. in this study 15 male trout fish (oncorhynchus mykiss) including 5 in the stage of grower, 5 before stripping and 5 after stripping randomly were considered. blood...

PURPOSE Pluripotent cells residing in the periosteum, a bi-layered membrane enveloping all bones, exhibit a remarkable regenerative capacity to fill in critical sized defects of the ovine femur within two weeks of treatment. Harnessing the regenerative power of the periosteum appears to be limited only by the amount of healthy periosteum available. Here we use a substitute periosteum, a deliver...

The present study was designed to evaluate the effects of platelet growth factors and periosteal mesenchymal stem cells on bone healing process, radiographically. Forty male White New Zealand rabbits in five equal groups were used in this study. A 2 mm full thickness bone defect was made in left radial bone of each animal. In group A (control) the defect was left with no medical intervention. I...
