Objective(s):Various methods for repairing bone defects are presented. Cell therapy is one of these methods. Bone marrow stromal cells (BMSCs) seem to be suitable for this purpose. On the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. Materials and Me...

We report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. Usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, II In these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

Bones are vital and strong, but not invincible—they can be broken. Normally, bones repair themselves. However, sometimes broken must supported using what is called an implant. An implant a man-made device used to replace or support missing part of the human body. In case bone, aims at helping bone regain its natural function. inserting foreign object into body has several possible complications...

Silk Fibroin-Coated Mg Implants for Bone Repair Engineering In article number 2101724, Hui Fang, Chenxi Wang, and co-workers demonstrate an effective O2/N2 hybrid plasma activation technology to modify alloy, achieving a robust organic protein/inorganic metal interface. The silk fibroin-coated implants possess significantly improved adhesion, anti-corrosion biocompatibility, which expands the b...

since bone marrow has been shown to contain osteoprogenitor cells, an experiment was devised to test its effects when injected percutaneously into osteotomies sites in rabbit radii. in this experimental study, the osteogenicity and its effect on early bone repair of bone marrow grafts were investigated. the purpose of this study was to determine whether bone marrow grafted percutaneously led to...

bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...
