Review Case Reports
Aneurysmal bone cyst of the spine treated by concentrated bone marrow: clinical cases and review of the literature.
ABC is a benign lesion with unpredictable behavior. Its treatment is challenging, especially in poorly accessible surgical areas, such as spine and pelvis. Currently, the first-line treatment of ABC is repeated selective arterial embolization (SAE) until healing. Other options have been used with variable success rates. We propose an alternative treatment for spine aneurysmal bone cyst (sABC) based on the injection of concentrated autologous bone marrow. ⋯ Although SAE can still be considered the first line in the treatment of ABC in the axial skeleton, new promising therapeutic procedures involving the use of mesenchymal stem cells are developing.
