The Jerosch score assesses osteolysis, premature resorption of the graft (1 point), unchanged size of the void, no resorption of the bone graft (2 points), beginning marginal bone-defect remodeling (3 points), bone-defect remodeling with nondirectional formation of trabeculae (4 points), and bone-defect remodeling with directional formation of trabeculae (5 points).
The values are given as the number of patients, with or without the percentage in parentheses.
