In recent years, synthetic hydroxyapatite (HAP) has attracted much interest because of the quest for new generation implants able to promote rapid osteointegration and having longer lifetimes. HAP a major inorganic component of bone, has been increasingly used as a bioceramic coating for load-bearing implants to improve fixation to natural bone tissue. In this study, HAP coating was synthesized using...
The purpose of this paper is to evaluate the biomechanical properties of a novel arthroscopic knot, Pretzel knot to be used in shoulder surgeries and compare it with two knots taken as standard: Samsung Medical Center(SMC) and Nicky's knots. Two groups have been formed: unbacked group (Pretzel and SMC knots), backed group (Pretzel, SMC and Nicky's knots backed with 3 RHAPs). Both groups have been...
Restoration of lost bones and their function is a major issue for bone tissue engineering. Although numerous synthetic biomaterials have been developed to overcome the problems associated with autologous or allogeneic therapeutic bone grafts, there remains a great challenge to design an idea bone substitute. Furthermore, electrospinning is an effective method of producing nano-fibrous structure. In...
Dual-energy techniques in radiography and computed tomography can allow for decomposition of projection images and reconstructed images into two components, representing, for instance, bone and soft tissue. There are a variety of approaches to performing this decomposition in the data domain, including direct solution of the pair of nonlinear equations for each line integral using, in one case, a...
