This study focuses on treating patients with delayed union or non-union long bone fractures, conditions where bones fail to heal properly after a fracture. Delayed union occurs when there are no signs of bone healing between 4 to 9 months after the initial fracture, while non-union refers to fractures that have not healed after 9 months following the injury.
The treatment being studied combines allogeneic bone marrow-derived mesenchymal stromal cells (ORTHOALLO-BM-MSC) with a special bone substitute material called MBCP+. This bone substitute is a ceramic material containing calcium phosphate that helps fill spaces in the bone. The purpose of the study is to determine if this combination treatment can achieve bone healing in patients with delayed or non-healing fractures.
The study will follow patients for 12 months after their surgical procedure. During this time, patients will undergo various evaluations, including imaging tests to check bone healing progress. The treatment involves a surgical procedure where the cell suspension is administered directly into the bone along with the bone substitute material.
