Summary: Goalkeepers are less likely to suffer fifth metatarsal stress fracture compared to other positions.

Purpose

Fifth metatarsal stress fracture is the most common stress fracture among soccer players. Patients with this fracture require surgery and it takes three months from operation to return to play because of high risk of nonunion and refracture.
The purpose of this study is to describe risk factors of fifth metatarsal stress fracture in soccer players.

Methods

This retrospective cohort study was approved by the institutional review board at Seirei Hamamatsu General Hospital (approval no.3739).
We retrospectively reviewed 95 feet of 81 soccer players who underwent operation in our hospital between April 1, 2006 and December 31, 2021 using electronic medical records and questionnaires.
Result:
The mean age was 19.0±4.2 years (range 14-43 years ). 63 players (78%) were elite and 32 played on artificial turf.
Playing positions were 3 goalkeeper’s feet, 32 defender’s feet, 35 midfielder’s feet, 15 forward’s feet. (10 feet were unknown.)
The stress fracture occurred in the non-dominant feet of 55% of defenders and midfielders and 53% of forwards. Outside defenders and midfielders were more likely to suffer the injury in the non-dominant feet (67% and 50%.respectively)compared to central defenders and midfielders(46% and 44%. respectively.)
Of the 95 injured feet, 14 (15%) occurred in February and 12(13%) in March.

Conclusion

Goalkeepers are less likely to suffer fifth metatarsal stress fracture compared to other positions. Outside defenders and midfielders are more likely to suffer the injury to the non-dominant leg.
In Japan, soccer players are more likely to be injured in February and March.
