transient osteoporosis
Transient osteoporosis is a self-limited condition characterized by reparative bone remodeling, which can affect all weight-bearing joints, being most common in the femoral head. For detailed description of that condition see transient ostoporosis of the hip.
Clinical presentation
Typical symptoms are pain with sudden onset in the affected joint, gait disturbance, limited range of motion. Regional migratory osteoporosis denotes a specific form of the disorder, in which the transient porosis migrates between joints .
Radiographic appearance
Plain radiograph
Osteopenia becomes visible with a delay of 4-8 weeks following symptom onset .
MRI
High T2/PDFS signal similarly to bone marrow edema without a fracture line or necrotic core .
Nuclear medicine
On bone scans the affected area shows increased radiotracer uptake, whilst e.g. avascular necrosis results in focal photopenia .
Differential diagnosis
- suchondral stress response
- subchondral insufficiency fracture
