In bone surgery, a corticotomy is a cutting of the bone that may or may not split it into two pieces (bone fracture) but involves only the cortex, leaving intact the medullary vessels and periosteum.
In the context of bone surgery, a corticotomy refers to a procedure that involves cutting through the outer layer of bone, potentially leading to a fracture if the bone is split. However, this technique preserves the inner medullary vessels and periosteum, which are crucial for bone repair.
