Stress Fracture Bone Stress Reaction Continuum

Classify bone stress injuries along the continuum from periosteal reaction to stress fracture and guide return-to-sport timelines by anatomical risk level.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Classify bone stress injuries along the continuum from periosteal reaction to stress fracture and guide return-to-sport timelines by anatomical risk level

Each component has a specific meaning:

  • Periosteal reaction — The periosteal reaction recorded for the scenario being assessed.

Note: Interpret the stress fracture continuum result against the thresholds and context described above.

How to Use

Enter the periosteal reaction for the scenario you are assessing. Classify bone stress injuries along the continuum from periosteal reaction to stress fracture and guide return-to-sport timelines by anatomical risk level. Use the stress fracture continuum result to inform your calculation.
