Lodwick-Madewell Classification (Lytic Bone Lesion)
1.0.0Grades radiographic aggressiveness of lytic bone lesions by margin and zone of transition (modified Lodwick-Madewell IA–IIIC). Higher grades imply faster growth and greater likelihood of malignancy, with important benign exceptions.

How this tool works
Lodwick correlated patterns of bone destruction with growth rate: geographic lesions with sclerotic or sharp margins grow slowly, while moth-eaten and permeative patterns grow rapidly. Madewell and colleagues refined margin concepts (including changing margination and radiographically occult disease). The 2016 modified Lodwick-Madewell system regroups patterns into grades that better track malignancy risk: grade I usually benign, grade II intermediate, grade III high likelihood of malignancy—while reminding readers that osteomyelitis and eosinophilic granuloma can mimic aggressive grades.
