Official Title: Autologous Transplantation of Bone Marrow Derived Mesenchymal Stem Cells in Distraction Osteogenesis in Patients With Limb-length Discrepancy
Brief Summary: Limb-length discrepancy can be due to many causes. These are divided into three groups: congenital (from birth), developmental (from a childhood disease or injury that slows or damages the growth plates), and posttraumatic (from a fracture that leads to shortening of the bone ends). There are three ways to equalize the limb-length discrepancy: use a shoe lift, shorten the long leg, lengthen the short leg. Most patients do not like wearing a lift greater than 2 cm (3/4 in). For discrepancies greater than 2 cm but less than 5 cm (2 in), shortening of the long leg can be considered, especially for tall persons. For growing children, this can be easily accomplished with a small, minimally invasive, uncomplicated procedure called epiphysiodesis.The investigators aim to evaluate if injection of bone marrow derived mesenchymal stem cells can shorten the treatment period by acceleration of bone regeneration during distraction osteogenesis.
