Demographics:
15 years old, Male
Indication:
Ankle injury
Findings
- Acute three-part Salter IV fracture of the distal tibia including a sagittally-oriented fracture of the distal tibial epiphysis, horizontal extension into the lateral aspect of the distal tibial physis, and continuation as a nondisplaced fracture extending vertically into the distal tibial metaphysis
- Additional 7 mm fracture fragment adjacent to the medial malleolus
- Ankle joint effusion
- Extensive soft tissue swelling about the ankle
- Os trigonum
Diagnosis
Triplane fracture
Sample Report
Acute three-part Salter IV fracture of the distal tibia including a sagittally-oriented fracture of the distal tibial epiphysis, horizontal extension into the lateral aspect of the distal tibial physis, and continuation as a nondisplaced fracture extending vertically into the distal tibial metaphysis (triplane fracture). Consider CT for further characterization.
Additional 7 mm fracture fragment adjacent to the medial malleolus consistent with chip/avulsion fracture.
Ankle joint effusion.
Extensive soft tissue swelling about the ankle.
Os trigonum, anatomic variant.
