==============================================
📌 Case 1: Tibial Tuberosity Fracture
- Radiograph: Minimally displaced fracture
- MRI: Distal tibial tubercle fracture with minimal separation
- Edema at fracture site, surrounding tissues, and Hoffa's fat pad
- Ogden classification: Type 1A
✅ Type I Fractures
Type I fractures involve only the distal portion of the tubercle.
- Type IA: Minimally displaced or non-displaced fracture.
- Type IB: Anterior and proximal displacement or comminution.
- Type IC: Proposed subtype for associated patellar tendon avulsions.
📌 Case 2: Cartilaginous Stage Osgood-Schlatter Disease
- Radiograph: May appear normal
- MRI: Incomplete transverse clefts in tuberosity's secondary ossification center
- Mild proximal tibial marrow edema and avulsed secondary ossification center
✅ Similarities:
- Proximal tibial marrow edema
- Secondary ossification center changes
- Patellar tendon thickening and signal alteration
- Deep infrapatellar bursitis and Hoffa's fat pad edema
✅ Key Differences:
- Fracture: Fracture line through tubercle ossification center
- Osgood-Schlatter: Transverse clefts in secondary ossification center
