Ilizarov method in combination with autologous mesenchymal stem cells from iliac crest shows improved outcome in tibial non-union

Publication date: May 2018Source: Saudi Journal of Biological Sciences, Volume 25, Issue 4Author(s): Hui Zhang, Feng Xue, Hai Jun XiaoAbstractAutologous bone grafting and ilizarov technique are the preferred mode of treatment for bone nonunion, studies suggest that bone marrow derived mesenchymal stem cells can be effective in treatment of tibial non-union where there is length of bone defect. The current study investigates the beneficial clinical outcome of combining the ilizarov procedure with intraosseous injection of autologous mesenchymal stem cells. The open-label study enrolled 25 patients with infected tibial non-union at the Shanghai Fengxian District Central Hospital, Shanghai, China between April 2010 and July 2014. Patients were randomised to undergo the ilizarov procedure with (n = 11) or without (n = 13) intraosseous injection of bone marrow derived mesenchymal stem cells. All participants were followed prospectively until union was achieved (primary end point). The mean length of the bone defect in the Ilizarov group and Ilizarov group plus MSC group was 6.09 and 5.84 cm respectively. The mean time from the original injury to the time of the treatment for tibial non-union was 5–22 months (mean 13.5 months) for the Ilizarov group and 6–21 months (mean 13.5 months) for Ilizarov plus MSc group. All 24 patients were followed up for 12–34 months (mean 16 months). Both groups achieved the primary endpoint o...
