Frame-Assisted Reduction of a B-Type Pilon Fracture Dislocation: Talar Body Incarceration on an Intact Fibula: A Case

Case:
We describe an irreducible anterolateral tibiotalar dislocation with an AO/OTA (Arbeitsgemeinschaft fur Osteosynthesefragen/Orthopaedic Trauma Association) B-type pilon fracture. The injury was initially treated with closed reduction, using a medializing force achieved with an external fixator to unhinge the talar body from the fibula, followed by temporary stabilization. Definitive fixation was performed once the soft tissues had recovered.
Conclusion:
This unique irreducible pilon fracture dislocation pattern is important to recognize to prevent iatrogenic complications associated with multiple failed closed reduction attempts. Frame-assisted, percutaneous, or open maneuvers may be required to facilitate a reduction. Staged treatment with temporization in an external fixator may be required.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
