The purpose of this study was to compare the results and complications of tibial lengthening over an intramedullary nail with treatment using the traditional Ilizarov method. In this matched case study, 16 adult patients underwent 19 tibial lengthening over nails (LON) procedures. For the matched case group, 17 patients who underwent 19 Ilizarov tibial lengthenings were retrospectively matched to the LON group.Objectives
Methods
Distraction osteogenesis (DO) mobilises bone regenerative potential and avoids the complications of other treatments such as bone graft. The major disadvantage of DO is the length of time required for bone consolidation. Mesenchymal stem cells (MSCs) have been used to promote bone formation with some good results. We hereby review the published literature on the use of MSCs in promoting bone consolidation during DO.Objectives
Methods
In order to ensure safety of the cell-based therapy for bone
regeneration, we examined BM cells obtained from a total of 13 Sprague-Dawley (SD) green
fluorescent protein transgenic (GFP-Tg) rats were culture-expanded
in an osteogenic differentiation medium for three weeks. Osteoblast-like
cells were then locally transplanted with collagen scaffolds to
the rat model of segmental bone defect. Donor cells were also intravenously infused
to the normal Sprague-Dawley (SD) rats for systemic biodistribution.
The flow cytometric and histological analyses were performed for
cellular tracking after transplantation.Objectives
