Composite materials for bone repair
2010Component selection and general design considerations are described for the production of inorganic/polymer composites for use in bone applications, with a focus on biodegradable systems. A review is presented of particulate composites (including nano-composites) with emphasis on the achievement of well-dispersed and well-bonded reinforcing phases ...

The role of pleiotrophin in bone repair
Injury, 2014Bone has an enormous capacity for growth, regeneration, and remodelling, largely due to induction of osteoblasts that are recruited to the site of bone formation. Although the pathways involved have not been fully elucidated, it is well accepted that the immediate environment of the cells is likely to play a role via cell–matrix interactions, mediated ...

Composite biomaterials for bone repair
2009The fast replacement of native functionality (i.e., biological, chemical, mechanical) of damaged skeletal tissues currently represents the main challenge of clinical surgery. Through an accurate study of natural tissues and biomimesis, advanced biomaterials can be designed in the form of porous scaffolds to create hierarchical porous structures with ...

Stimulation of bone repair by ultrasound
International Journal of Rehabilitation Research, 1985The repair of fibular fractures has been accelerated and modified by treatment with ultrasound. Complete bilateral transverse fibular fractures were made in adult female Wistar rats. Twelve were maintained as untreated controls. In seventy rats, one fracture was treated with ultrasound and the other mock-irradiated.

Role of angiogenesis in bone repair
Archives of Biochemistry and Biophysics, 2014Bone vasculature plays a vital role in bone development, remodeling and homeostasis. New blood vessel formation is crucial during both primary bone development as well as fracture repair in adults. Both bone repair and bone remodeling involve the activation and complex interaction between angiogenic and osteogenic pathways.

The role of growth factors (GF) in bone repair is widely recognised, particularly for bone morphogenetic proteins (BMPs), fibroblast growth factor (FGF), insulin-like growth factors (IGFs), platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-beta) and vascular endothelial growth factor (VEGF).

Electrical Stimulation of Bone Repair
Clinics in Podiatric Medicine and Surgery, 1991Interest in methods of accelerating bone healing persists. Electrical stimulation has demonstrated consistently high success rates in recalcitrant, complicated nonunions. The promise of successful noninvasive alternatives for treating nonunions continues to be realized.

Mechanotransduction in bone repair and regeneration
The FASEB Journal, 2010ABSTRACT Mechanotransduction is the process by which physical forces are converted into biochemical signals that are then integrated into cellular responses. It plays a crucial role in bone repair and regeneration and thus has attracted a great deal of interest from researchers in various fields.

Development of polyurethanes for bone repair
Materials Science and Engineering: C, 2017The purpose of this paper is to review recent developments on polyurethanes aimed at the design, synthesis, modifications, and biological properties in the field of bone tissue engineering. Different polyurethane systems are presented and discussed in terms of biodegradation, biocompatibility and bioactivity.

The Biology of Bone Graft Repair
Clinical Orthopaedics and Related Research, 1983Cancellous and cortical autografts histologically have three differences: (1) cancellous grafts are revascularized more rapidly and completely than cortical grafts; (2) creeping substitution of cancellous bone initially involves an appositional bone formation phase, followed by a resorptive phase, whereas cortical grafts undergo a reverse creeping ...
