Jones Fracture in the Nonathletic Population.

Fractures of the proximal fifth metatarsal are common injuries with a unique history. Treatment of these fractures is controversial partly because of confusion regarding fracture subtype nomenclature. Today "Jones fracture" refers to proximal fifth metatarsal fracture in zones 2 or 3. Zone 2 fractures are acute injuries, and their optimal treatment is unclear. Zone 3 fractures commonly occur in the presence of a chronic stress reaction. Because of poor healing potential, zone 3 fractures typically require operative treatment. Zone 1 fractures have excellent healing potential and may be treated nonoperatively with a weightbearing as tolerated protocol.
