Metacarpal Stress Fractures in Athletes: A Systematic Review

Abstract

Background:

Stress fractures in general are common injuries; however, there is limited literature on metacarpal stress fractures in athletes. Our objective is to contribute the first systematic review of metacarpal stress fractures in athletes, with a particular focus on epidemiology, presentation, and outcomes.

Methods:

A systematic review regarding metacarpal stress fractures in athletes was performed via PubMed, EMBASE, MedLine, Cochrane, and Web of Science. Inclusion criteria consisted of case reports and case series of metacarpal stress fractures in athletes. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed.

Results:

A total of 11 studies (29 cases) were included. The mean patient age was 17 years, with 12 men and 15 women. The most common sports were tennis and badminton. The most common presentation was pain in the dorsal aspect of the hand related to activity. All patients underwent successful nonoperative management, with mean return to play of 9 weeks.

Conclusions:

Metacarpal stress fractures can present with significant pain and impact performance in athletes who perform sports involving repetitive movements of the hand and wrist. Nonoperative treatment, consisting of abstinence from sport until the patient was pain free combined with gradual return to play, was successful for all patients. The addition of proper technique and training load can result in satisfactory return to play. For patients who present with hand pain related to exercise, particularly a young racquet sport player, metacarpal stress fractures are a “can’t miss” diagnosis associated with significant functional impairment.
