CASE STUDY
✅Avulsion fracture at the medial collateral ligament's epicondylar attachment.
✅ Key findings on imaging include:
- Avulsion fracture of the MCL visible, without displacement
- Continuity of the fracture fragment with the MCL on MRI
- Associated extracapsular hemorrhage appearing hyperintense
- Fracture line is hyperintense surrounded by bone marrow edema, making it less apparent on fat-suppressed images
- Fracture line appears as linear hypointensity on T1-weighted MRI
✅Note
It's important to assess for associated injuries like bone marrow edema, injury to posteromedial corner structures, deep MCL, medial meniscus, and cruciate ligaments which can accompany this type of avulsion fracture.
