Opening- and closing-wedge osteotomy
An osteotomy is a surgical procedure to cut and re-align a bone. In an 'opening wedge' osteotomy, laminar spreaders open the wedge in the bone which is held in the new position with a plate and screws until new bone fills the gap. In a closing wedge osteotomy, a wedge of bone is removed and the gap closed and plated.
