Stress Fracture Foot, Stress Fracture Ankle
Detecting and Assessing Leg and Foot Stress Fractures Using Photon Counting CT
Stress fractures (fatigue or insufficiency fracture) are caused by the mismatch between bone strength and chronic stress applied to the bone. The vast majority of these fractures occur in the lower extremity.

- Stress Fracture Foot, Stress Fracture Ankle, Stress Fracture of Tibia, Stress Fracture Metatarsal
- Trial name
- FootPCCT (NCT06024798)
- Testing
- Photon-Counting-Computed-Tomography
- Where
- Switzerland
- Volunteers
- 50 people
