Stem cells could mend broken bones that Won't heal

This study tests a new way to repair large bone gaps in arms or legs that are not healing properly. Doctors will take a small sample of the patient's own bone marrow, grow the stem cells in a lab, and combine them with a special scaffold to create living bone tissue. This tissue-engineered bone is then placed into the defect during surgery. The goal is to see if this approach helps bones heal faster and more completely than standard treatments. The study involves 30 adults aged 18 to 55 with bone defects of 2-3 cm or bone cysts affecting more than half the bone's width.
