Time and rate of return to sport after stress fracture

Time and rate of return to sport after stress fracture
Stress fracture type Average recovery time Rate of return to full sports (%)
Tibia (posteromedial) 6 weeks (range 2 to 7) 98
Fibula 8 weeks 90
Metatarsals 1, 2, 3, 4 (not proximal) 11 weeks (range 3 to 12) 96
Pubis 11 weeks 96
5th metatarsal 12 weeks 95
Femoral shaft 12 weeks 95
Medial malleolus 15 weeks 93
Femoral neck (compression-side fractures treated nonsurgically) 15 weeks (range 4 to 32); average 7.4 weeks if MRI grade 1 and 15 weeks if MRI grade 2 to 4 55
Tarsal navicular 18 weeks 83
Low-risk site* and low-grade severity on MRI/bone scan 8.7 weeks  
High-riskΔ site and low-grade severity on MRI/bone scan 19.3 weeks  
Low-risk site and high-grade◊ severity on MRI/bone scan 21.8 weeks  
High-risk site and high-grade severity on MRI/bone scan 18.7 weeks  
This table summarizes the evidence about the time needed to return to full sport following a stress fracture. The time and rate of return vary by the location, including whether the fracture occurred at a high-risk or low-risk site, and the severity of injury.

MRI: magnetic resonance imaging.

* Low-risk sites: Metatarsal shafts 2, 3, and 4; posterior tibial cortex; fibula; tarsals other than talus or navicular; pelvis; femoral shaft.

¶ Low-grade severity: Grades 1 or 2 on MRI or bone scan.

Δ High-risk sites: Base of 2nd metatarsal, 5th metatarsal, tarsal navicular, talus, medial malleolus, anterior tibia, femoral neck, patella, great toe sesamoids, pars interarticularis.

◊ High-grade severity: Grades 3 or 4 on MRI or bone scan.
