Unfused tibial tubercle

Case contributed by Ammar Haouimi
Diagnosis probable

Presentation

Recent sport injury.

Patient Data

Age: 30 years
Gender: Male
x-ray

There is a bony fragment visible anterior to the proximal tibia with no adjacent soft tissue edema in keeping with an unfused ossification center of the tibial tubercle. No bony fracture is seen.

Case Discussion

The radiological appearance in addition to the absence of pain or swelling at the same level is suggestive of an unfused ossification center of the tibial tubercle (incidental finding), and should not be mistaken for an avulsion fracture of the tibial tuberosity or Osgood-Schlatter disease.
