Strontium doping of bone graft extender
BACKGROUND AND PURPOSE Allografts are often used during revision hip replacement surgery for stabilization of the implant. Resorption of the allograft may exceed new bone formation, and instability of the prosthesis can develop. We investigated whether strontium could regulate the imbalance of fast resorption of allograft and slower formation of new bone, because it is both an anabolic and an a...
متن کاملPorous Allograft Bone Scaffolds: Doping with Strontium
Strontium (Sr) can promote the process of bone formation. To improve bioactivity, porous allograft bone scaffolds (ABS) were doped with Sr and the mechanical strength and bioactivity of the scaffolds were evaluated. Sr-doped ABS were prepared using the ion exchange method. The density and distribution of Sr in bone scaffolds were investigated by inductively coupled plasma optical emission spect...
متن کاملLumbar posterolateral fusion with local bone graft plus bone extender compared with iliac crest bone graft: a systematic review
STUDY DESIGN Systematic review. Study rationale and context: Bone graft from the iliac crest has been the gold standard in posterolateral spinal fusion procedures, but is associated with chronic pain at the harvest site. Bone graft harvested locally from the spine and combined with extenders may decrease the morbidity associated with iliac graft harvest, but questions remain on the success of...
متن کاملPorous Strontium-Containing Ceramic Granules as Bone Graft Substitutes
We have synthesized calcium phosphate-based, strontium (Sr) containing, porous ceramic granules for use as bone graft substitutes. The granules with a particle size between 1 and 2 mm and a (macro)-pore size around 200–500μm were mixed with a fibrin sealant to form a moldable composite material. The starting material with Sr contents between 0 and 100% Sr were precipitated from Ca/Sr solutions ...
متن کاملEffect of Strontium Doping on Magnetic Properties of Neodymium Orthoferrimanganites
Copyright 1996-2012 Researchpub.org. All rights Reserved. 18 Abstract— The effect of strontium dopping on magnetic properties of neodymium orthoferrimanganites have been investigated using neutron diffraction and MÖssbauer spectroscopy. All samples prepared using solid state reaction from pure oxides. The XRD reflections exhibited single phase structure of both samples. The neutron diffraction...
