IMibf stands for "Induced Membrane for Bone Formation," which is a technique used in orthopedic surgery to facilitate bone healing in cases of large bone defects or non-union fractures. The method involves creating a membrane that promotes the growth of new bone tissue by using a combination of biocompatible materials and growth factors. This induced membrane enhances the biological environment necessary for successful bone regeneration. It is particularly beneficial in complex cases where traditional methods may not be effective.
