“…With relation to the likely high impact and rotational forces involved, an MRI scan is useful in identifying concurrent soft tissue injury of the knee joint, such as associated intra-articular injury to the ACL, assessment of the physeal plate, as well as to identify any soft tissue trapping within the fracture site preventing adequate reduction. In our case and as documented by Nowicki et al ,17 periosteal trapping is not uncommon. As such, we recommend MRI scans for all suspected triplane injuries of the proximal tibia with a low threshold for open reduction and internal fixation, to clear the likely presence of a periosteal sleeve caught within the fracture fragment.…”
