The blood supply disorder is one of the main reasons that lead to the morbidity and difficulty in healing of diabetes feet, but there is still a lack of particularly effective treatment to improve the blood supply of diabetes feet. Both transverse bone transport and bone marrow cell transplantation have shown some clinical effects. However, the difference in efficacy between the two has not been reported. In this study, investigators compared the therapeutic effects of these two methods on the healing of diabetes foot ulcers through a controlled clinical study.
