Magnetic resonance imaging is a useful tool for stress fractures (SF) diagnosis, allowing the estimation of injury severity. The aim of this study was to determine the relation between the severity of SF in athletes determined by magnetic resonance imaging and the morbidity estimated as the time to return to sport. Thirty-four cases of stress fractures, (29 athletes; 12 female, 17 male; age 26.3 +/- 12.5), were studied by radiographs and magnetic resonance imaging. Injuries were classified

The tibia was the most affected bone (n=12; 35.2%), followed by the tarsal navicular (n=5; 14.7%), and the metatarsals (n=4; 11.7%). Injury severity according to magnetic resonance imaging appearance was: grade 1=14.7%; grade 2=14.7%; grade 3=38.2%; grade 4=32.4%. The main finding was the positive significant correlation between injury severity and recovery time (r=0.66, p=0.0002). In conclusion, significant correlation exists between stress fracture injury severity determined by magnetic resonance image and recovery time in athletes. The use of a systematic graded magnetic resonance image evaluation may assist the physician to define clinical management, supervise the rehabilitation program and estimate the return to sport activity.
