Running stress fractures — tibia, metatarsals, fibula, femoral neck, navicular — are season-ending without proper management. PEMF therapy is FDA-cleared specifically for non-union fractures and accelerates union in confirmed stress fractures. The strongest single evidence base in PEMF therapy applies directly here. See our dedicated stress fracture guide.
Quick facts
- FDA-cleared: Yes — non-union fractures since 1979
- Common sites: Tibia, metatarsals, fibula, femoral neck, navicular
- Higher-risk sites: Anterior tibia, navicular, femoral neck
- Sessions: 3× per week for 6–8 weeks
- Recovery: 6–12 weeks
Why this injury happens in this sport
Sudden volume increases, RED-S (energy availability), and biomechanical risk factors all contribute. Imaging is essential.
Recovery and return to sport
Strict load reduction. Cross-train without impact. PEMF 3× per week directly over the fracture site. High-risk sites (anterior tibia, navicular, femoral neck) need orthopaedic specialist input.
Contraindications
Standard PEMF contraindications: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.
Frequently asked questions
Will PEMF help my femoral neck stress fracture?
Yes — but femoral neck stress fractures need urgent specialist orthopaedic management because they can progress to complete fracture requiring surgery.
Can I keep running cross-training?
Cycling and swimming usually fine. Aqua-jogging is excellent. Continued running impact delays healing.
