Abstract:

Large skeletal defects are often encountered in the surgery of bone tumours, revision arthroplasty and trauma. Skeletal stability can be restored using either large endoprostheses or structural allografts. The latter have the advantage of restoring bone in the defect. However, transplantation of allograft bone carries with it the risk of transmissal of contaminant or blood borne infection. Sterilisation of such grafts is commonly performed by the use of gamma irradiation. The first part of this study was the audit of an allograft bank to determine the incidence of contamination of the grafts a

Abstract:

Bone grafts are used to treat more than 300,000 fracture patients yearly, as well as patients with congenital defects, bone tumors, and those undergoing spinal fusion. Given the established limitations of autograft and allograft bone, there is a substantial need for bone graft substitutes. Tissue engineering strategies employing the addition of osteogenic cells and/or osteoinductive factors to porous scaffolds represent a promising alternative to traditional bone grafts. While many bone defects are in load-bearing sites, very little is known about the response of bone grafts and their subst

Abstract:

Bone and cartilage constructs are often plagued with mechanical failure, poor nutrient transport, poor tissue ingrowth, and necrosis of embedded cells. However, advances in computer aided design (CAD) and computational modeling enable the design of scaffolds with complex internal michroarchitectures and the a priori prediction of their transport and mechanical properties, such that the design of constructs satisfying the needs of the tissue environment can be optimized. The goal of this research is to investigate the capability of additive manufacturing technologies to create designed microarc

L’hydroxyapatite (HA) est largement utilisée pour l’élaboration de substituts osseux. En effet, lorsque le défaut osseux est trop important, la réparation naturelle ne peut avoir lieu.

De plus, ses propriétés d’ostéoconduction permettent une colonisation efficace des cellules sur le substitut favorisant la formation d’os nouveau.

Abstract:

Polylactic acid (PLA) has emerged as a promising material for bone scaffolds due to its biocompatibility, controlled degradation, and suitability for additive manufacturing. However, polymeric scaffolds often face challenges in achieving adequate mechanical strength which compromise their effectiveness as load-bearing supports during bone healing. Hence, evaluating and improving their fatigue performance is essential to meet the required strength. Existing studies have mainly focused on mechanical properties of polymeric scaffolds under static loading, while their performance under cyclic load

Lorsque le défaut atteint un stade critique, la régénération osseuse est impossible et on assiste à une perte de fonction.

This doctoral work was developed in the frame of bone tissue engineering, dealing with the fabrication of scaffolds for the regeneration of bones.

Abstract:

One of the greatest obstacles to clinical translation of bone tissue engineering is the inability to effectively and efficiently vascularise scaffolds. This limits the size of defects that can be repaired, as blood perfusion is necessary to provide nutrient and waste exchange to tissue at the core of scaffolds.

A pipeline was developed for the production of hydroxyapatite surfaces with controlled architecture.

Υλικό–Μέθοδος: Στην παρούσα μελέτη χρησιμοποιήθηκαν 90 κουνέλια Νέας Ζηλανδίας, ηλικία 3.5 μηνών και βάρους 4(0.25)kg, τα οποία χωρίσθηκαν σε 6 ομάδες, η κάθε μία εκ των οποίων περιελάμβανε 15 κουνέλια. Υπό γενική αναισθησία, με ενδομυϊκή χορήγηση κεταμίνης 35mg/kg και ξυλαζίνης 5mg/kg, δημιουργήθηκε, με πλάγια χειρουργική προσπέλαση, μια οπή με φρέζα διαμέτρου 4.5mm και βάθους 8mm, στους μηριαίους κονδύλους των 2 οπισθίων ά

Abstract:

The focus of this dissertation is on the development of a solid freeform fabrication (SFF) process for the design and manufacture of porous biodegradable orthopaedic implants from calcium polyphosphate (CPP). Porous CPP structures are used as bone substitutes for regenerating bone defects and/or as substrates in formation of so-called “biphasic” implants for repair of damaged osteochondral tissues. The CPP implants can be utilized in the treatment of many musculoskeletal diseases, osteochondral defects, and bone tumours while replacement of the defect site is required. In this study, the fabr
