Torg's classification of proximal fifth metatarsal fractures is based on the degree of sclerosis adjacent to the fracture on imaging at the time of presentation to determine the fracture age.
Classification
Type I
- narrow fracture line with sharp margins and no widening
- minimal cortical hypertrophy
- no intramedullary sclerosis
Type II
- wide fracture line with adjacent lucency
- fracture line involving both cortices
- partial obliteration of medullary canal by sclerosis at the site of fracture
Type III
- wide fracture line
- periosteal new bone formation
- complete obliteration of medullary canal by sclerosis at the site of fracture
