What is Bone Marrow Edema?

What Causes Bone Marrow Edema?

Loading a bone beyond its usual capacity, an impact, an early stress fracture, cartilage damage or inflammation can change fluid balance and circulation inside bone. The bright MRI area is not a diagnosis by itself; it is an imaging finding interpreted according to the underlying cause.

Symptoms

• Deep bone pain that increases with weight bearing and eases with rest
• Ache that persists at night or after activity
• Restricted movement and difficulty loading the nearby joint
• Focal tenderness and sometimes swelling after an impact

Frequently Asked Questions

Does bone marrow edema always mean a stress fracture?

No. It can occur with a stress fracture, but impact, cartilage problems and other joint conditions can produce the same finding. Examination, X-rays and MRI are considered together; reducing painful load and arranging controlled follow-up may be needed while the cause is clarified.
