Scientific titleTreatment of early stage osteonecrosis of the femoral head with implantation of autologous bone marrow-derived and cultured mesenchymal stem cells: a single centre randomised controlled interventional trial
Study acronymCD-BMMSC treatment
Study objectivesBone marrow-derived mesenchymal stem cell implantation into the femoral head is effective in treating early stage osteonecrosis of the femoral head, and the number of these mesenchymal stem cells implanted is crucial to the clinical outcome. The hypothesis of this study is to isolate bone marrow mesenchymal stem cells and grow them in vitro to obtain greater number of such cells for femoral head implantation, in order to achieve better clinical outcome.
Ethics approval(s)Approved by the Public Health Bureau, the City of Dalian, and the State FDA, China in 2002 (ref: 02-88), 2005 (ref: 05-183) and 2008 (ref: 08-179)
Health condition(s) or problem(s) studiedOsteonecrosis of the femoral head at early stage
InterventionOsteonecrosis of the femoral head remains a significant health concern. Currently, core decompression combined with implantation of autologous bone marrow mononuclear cells appears to be an effective treatment against this disease in the early stage. Among the bone morrow mononuclear cells, mesenchymal stem cells (MSCs) are crucial to the efficacy. The number of mesenchymal stem cells (MSCs) in the bone marrow mononuclear cells is very limited, which are crucial to the efficacy of the treatment. Therefore, the aim of our trial is to obtain greater number of bone marrow MSCs through culturing bone marrow-derived mesenchymal stem cells in vitro, and transplant these cultured bone marrow MSCs into the affected femoral head following the procedure of core decompression. In our procedure, about two million cultured bone marrow MSCs could be implanted into the femoral head, compared with that about 20 - 25 thousand MSCs implanted into the femoral head in the procedure employed by other groups, therefore, we expect our procedure could lead to higher clinical and radiographic success rate and better clinical outcome.

Procedure:
1. Isolate mesenchymal stem cells from the autologous bone marrow mononuclear cells
2. The patients are treated with core decompression
3. The cultured stem cells are injected into the femoral head

The duration of our treatment is about 2 weeks. Bone marrow aspiration is performed in the same day of the surgery core decompression, then autologous bone marrow-derived and cultured mesenchymal stem cells are transplanted into the femoral head two weeks post-operatively.

The patient enrolment period was designed from 04 March 2004 to 01 September 2011. Our first manuscript will report the outcome by the 30-month follow-up. We will keep following up the patients as long as we can, at least for 8 years.
Intervention typeOther
Primary outcome measureClinical outcome, assessed by the Harris Hip Score, measured pre-operatively and at 3 months, 6 months, 12 months, 30 months, and every 2 years post-operatively thereafter
Secondary outcome measuresRadiographic approaches are used to determine the progress in osteonecrotic stage and to assess the volume of the necrotic lesion in the femoral head, measured pre-operatively and at 3 months, 6 months, 12 months, 30 months, and every 2 years post-operatively thereafter
