Avulsion fractures: a bandage, shoe or boot does as well as a castStrong evidence
In a UK trial of 60 people, a double elasticated bandage for 4 weeks was as good as a below-knee walking cast at 4 weeks and 6 months, though 43% weren't followed up to 6 months. In a trial of 96, walking in a hard-soled shoe was as good as a short leg cast for pain at 6 months, and people got back to their usual activities sooner (37 against 43 days). In one small UK comparison of 37 people, a plaster slipper gave better scores than an elastic bandage at 2 weeks, but they were the same by 6 weeks.
In a UK comparison of 39 people that wasn't randomised, a walking boot gave better function than a walking cast, and people drove again sooner. A boot or a hard-soled shoe gave similar pain and function in 72 people. Reviews found removable supports gave better early function than casts, and non-union in about 1% of these breaks.

Jones fractures: slower to heal, and hospitals differMixed evidence
Across 10 studies (998 people), non-union was 11.6% with non-surgical care and 3.3% after surgery, with fewer complications and better foot scores after surgery; most of the studies weren't randomised, and some mixed sudden breaks with stress fractures. In the one main trial (37 people), 8 of 18 treated in a cast without weight failed (5 didn't heal, 1 healed slowly and 2 broke again), against 1 of 19 after a screw.
But in a UK virtual fracture clinic that put every fifth metatarsal fracture in a boot with full weight (663 people, 111 Jones fractures), 8 Jones fractures (7%) didn't join, none caused symptoms, and 1 person needed an operation; another UK clinic using the same approach had 1 non-union among 126 people. A trial of 72 found early walking did as well as 8 weeks in a cast or boot for zone 2 fractures.
NHS trust leaflets describe treatment without surgery at first, by a boot and walking or by a cast without weight, and we found no national survey of what UK clinics do. Surgery is sometimes offered, especially to athletes and people with physically demanding jobs.

Athletes: a screw speeds the returnEmerging evidence
In 22 studies of 646 Jones fractures in athletes, 98.8% returned to play after a screw against 71.6% without surgery, at about 10 weeks against 13, and the bone healed sooner (about 8 against 14 weeks); about 1 in 10 broke again across the studies. The review's authors recommend a screw for athletes, and an international consensus found return to sport was quicker after surgery. Going back before the X-ray shows healing isn't advised, because of the risk of breaking it again.
In elite men's football, just over half of fifth metatarsal fractures were stress fractures, and 45% of players had warning pain beforehand. The evidence is mostly from studies that weren't randomised.

Spiral shaft (dancer's) fractures usually heal without surgeryEmerging evidence
All 33 displaced spiral fractures in a London series healed without surgery, and a rigid-soled shoe gave pain-free walking sooner than a boot (4.6 against 8.4 weeks). In a US cohort of 142 treated without surgery, function was excellent at 3.5 years and 2 needed surgery for a painful non-union. In a review of 490 people, about 99% healed with or without surgery, but athletes returned to sport sooner after surgery (15.4 against 22.4 weeks).

Exercise after a broken foot: practice-basedEmerging evidence
Fracture clinic letters start ankle and foot movements straight away: point the foot up and down, circle it and spread the toes, 10 of each, 3 to 4 times a day. One NHS fracture clinic advises building back to training by no more than 10% a week, and the balance holds here come from the NHS balance exercises. We found no trials testing exercise programmes after metatarsal fractures, so the later stages and milestones here are editorial, following our broken ankle and stress fracture guides.
