In vitro and in vivo evaluation of a novel polymer-ceramic composite scaffold for bone tissue engineering

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006

Currently available bone grafts present certain limitations such as donor-site morbidity for autografts and risk of disease transmission for allografts. These limitations suggest a need for alternative strategies. The use of polymer/ceramic composites as scaffolds for trabecular bone tissue engineering capitalizes on the benefits of both materials. Polymers are easily formed and shaped and add structural rigidity while calcium phosphates ...

Vesselness-guided variational segmentation of cellular networks from 3D micro-CT

2010 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2010

Advances in imaging techniques lead to nondestructive 3D visualization of biological tissue at a sub-cellular scale. As a consequence, new demands emerge to segment complex structures. For instance, synchrotron radiation micro-CT, makes it possible to image the lacunar-canalicular porosity in bone tissue. This structure contains a dense network of slender channels interconnecting the cells. Their size (~300-600 nanometers in diameter) ...


Bio-compatible ceramics as mimetic material for bone tissue substitution

Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials. IPMM'99 (Cat. No.99EX296), 1999

Bone-like apatite formation on the surface of implant is of key importance during the physical and chemical processes leading to the formation of bonds between the implanted material and the newly formed bone tissue. The smartness of such a mimetic process is likely the action of silanole groups (Si-OH) which serve as the nucleation sites for the biocompatible interface formation ...

  • In vitro and in vivo evaluation of a novel polymer-ceramic composite scaffold for bone tissue engineering

    Currently available bone grafts present certain limitations such as donor-site morbidity for autografts and risk of disease transmission for allografts. These limitations suggest a need for alternative strategies. The use of polymer/ceramic composites as scaffolds for trabecular bone tissue engineering capitalizes on the benefits of both materials. Polymers are easily formed and shaped and add structural rigidity while calcium phosphates impart osteoconductivity and osteointegration. We have developed a biodegradable, microsphere-based scaffold for bone tissue engineering based on poly(lactide- co-glycolide)/calcium phosphate composite microspheres in which a nanocrystalline hydroxyapatite is synthesized within the forming microspheres.

  • The effects of fluoride ions (F/sup -/) on the mechanical properties of bovine bone tissue with different ultrastructures

    Bovine cortical bone samples were tested in tension after being treated for three days in a 2.0M NaP solution. Randomly selected bone samples were obtained from 18 month old steer, 24 month old cow and 96 month old cow. The elastic modulus (E) and ultimate tensile stress (UTS) were obtained for a control group (0.145M saline) and a fluoride group for each age of bovine. The fluoride ion (F/sup -/) content of the bone was also measured to approximate the amount of absorption of the test conditions (0.952%). The results showed that fluoride ions induced a more pronounced effect on younger bone causing a greater overall decrease in E and UTS. The decrease in mechanical properties occurs because fluoride is thought to influence the interphasic bonding between the carbonated hydroxyapatite mineral and organic phases present in bone along with the bone mineral structure.

  • Application of wavelet analysis to ultrasonic characterization of bone

    Investigates the application of time-frequency techniques to ultrasonic signals transmitted through bone to noninvasively determine bone density and strength. Ultrasonic transmission measurements are carried out on 3 samples of human vertebral trabecular bone, using a 1 MHz transducer pair. The data is processed using the wavelet transform according to Mallat's (1989) pyramid algorithm. The wavelet representation thus obtained is then cross-correlated with a wavelet representation of a reference signal to obtain the time- frequency representation associated with a particular bone sample. Results indicate that time-frequency methods may serve to accurately discriminate bone in various biophysical states. Further studies are under way to determine the best set of features associated with the time-frequency representation as well as the optimal means for processing the feature set, including neural networks.<<ETX>>

  • Vesselness-guided variational segmentation of cellular networks from 3D micro-CT

    Advances in imaging techniques lead to nondestructive 3D visualization of biological tissue at a sub-cellular scale. As a consequence, new demands emerge to segment complex structures. For instance, synchrotron radiation micro-CT, makes it possible to image the lacunar-canalicular porosity in bone tissue. This structure contains a dense network of slender channels interconnecting the cells. Their size (~300-600 nanometers in diameter) is at the limit of the acquisition system resolution (280 nm) making their detection difficult. In this work is proposed a variational region growing segmentation method adapted for cellular networks. To control the evolution of the segmentation through tubular structures a vesselness map is introduced in the expression of the functional to minimize. The method is tested on synthetic images and applied to experimental data.

  • Bio-compatible ceramics as mimetic material for bone tissue substitution

    Bone-like apatite formation on the surface of implant is of key importance during the physical and chemical processes leading to the formation of bonds between the implanted material and the newly formed bone tissue. The smartness of such a mimetic process is likely the action of silanole groups (Si-OH) which serve as the nucleation sites for the biocompatible interface formation capable to coexist between the original tissue and the implants which can be made from ceramics, glass-ceramics, composites as well as certain metals (titanium) respecting the condition of suitable surface reactivity. Lasak Co. Ltd. is the leading manufacturer of these materials in the Czech Republic and provides various kinds of bioactive implants, based on calcium phosphate ceramics, apatite wollastonite glass-ceramics and implants with hydroxyapatite surface coatings, permitting differentiated applications in clinical practice. The bioactive materials used as bone substitutes are all the subject of continuing research to attain biological, mechanical and chemical properties as similar as possible to those of the tissue to be replaced-mimetic materials. Clinical applications in orthopaedics, neurosurgery, maxillofacial surgery, auricular surgery, dental surgery and in other fields are demonstrated.

  • Effects of ovariectomization on interfacial interactions of cortical bone in the rat femur

    In recent years, many researchers have studied the changes in bone mass and biomechanical competence in relation to age and sex hormones due to the increase awareness of osteoporosis in the elderly. The objective of this study was to determine the effects of ovariectomization and aging on the cortical bone of the rat femur concentrating on the biomechanical properties and bone mass. The fluoride treatment technique was employed to understand the relationship between the biomechanical properties and the interfacial interactions between the mineral-organic interface of the cortical bone.

  • Treatment of standardized fractures by extracorporeal shock wave therapy (ESWT)

    ESWT is used in treatment of pseudoarthrosis and may be considered for callus lengthening operations. In this study, effects of ESWT on the forming callus were studied. Transverse femoral osteotomy at mid diaphysis, internally fixated with Kirschner wires were performed on 20 male, ten-week-old white Wistar rats. In the third week animals underwent ESWT with 1500 (Group I) and 500 (Group II) shock waves/treatment at a generating voltage of 10 kV on their right femurs; left femurs were used as controls. In the nineth week animals were sacrificed. X-Ray and computerized tomographical analyses on both femurs were done. X-Ray data showed that bone tissue of Group I displayed a higher percentage of nonunions and secondary axial displacements than Group II. Group II had a higher percentage of unions and fewer secondary axial displacements than Group I. The radiological scores for 500-sw/treatment group were 67% of the controls. CT data showed that ESW treated right legs in both groups had a greater callus area, and lower average density of image pixel than controls. In agreement with other studies done on healing bone, no significant correlation between callus area and the level of bone healing was found.

  • The in vivo mechanical loading history of bone

    Recent work to quantify a bone's strain history illustrates the complexity of its in vivo mechanical loading, a complexity similar to that found in many other physiological systems. Further quantification of the mechanical loading of bone will help one to understand the mechanism of the bone mechanosensory system and will also be useful as a physiological input for in vitro and in vivo bone experiments as well as for input for computational models of bone adaptation.

  • P3F-7 Impact of Microstructure on Elastic Behavior of Cortical Bone

    The axial transmission technique dedicated to clinical assessment of cortical bone involves propagation of various propagation modes such as Lamb type modes or lateral wave. As revealed by in vitro experiments, velocities of these elastic waves reflect a combination of bone properties, which themselves are highly related to bone strength: cortical thickness, porosity, elastic impedance and mineral content of the bone tissue. Assuming that bone properties could be evaluated from measured velocities, we investigated the sensitivity of elastic waves to these different bone properties, particularly to porosity, on the basis of finite difference time domain simulation approach. Results exhibit quadratic variations of the compression and shear velocity with porosity. For a typical transversely isotropic bone matrix, an increase of the porosity from 0% to 10% leads to a 4%-decrease of the compression velocity along the axial direction and an 11%-decrease of the compression velocity along the transverse direction, resulting in an increase of anisotropy (ratio c<sub>33</sub>/c<sub>11</sub> of 17%. The impact of porosity on a specific propagation mode (S<sub>0</sub> Lamb-mode type) used in axial transmission was derived

  • On effective properties of heterogeneous bone scaffold

    Scaffold material, porosity and internal pore architecture are essential parameters for bone scaffold design that affect both scaffold function and cell-tissue ingrowth. A general approach for design of bone scaffold is to mimic natural tissue properties, namely, the tissue heterogeneity and anisotropy. This paper presents a modified multi-cell model that can be used to predict the effective properties of heterogeneous bone scaffolds with an improved accuracy. Results from the model prediction are reported.
