A Jones fracture is a specific break at the base of the fifth metatarsal (the long bone connecting to your little toe), occurring 1.5-3cm from the bone end in a zone with poor blood supply, typically from twisting injury on outside of foot, sudden pivoting in basketball/football, or repeated stress in runners and dancers—causing pain, swelling, and difficulty walking on outside of foot. Jones fractures are notorious for slow healing and high nonunion rate (20-30% fail to heal with boot/cast alone) due to poor blood supply to this zone, making surgical screw fixation the preferred treatment for athletes and active individuals (90-95% union rate, return to sport 6-10 weeks), while non-surgical treatment reserved for low-demand patients willing to accept longer recovery (12-20 weeks) and risk of nonunion requiring delayed surgery.
