Retrograde reduction for a depressed talus fracture concomitant with a pilon fracture: A case report

Background

A depressed talus fracture is rare and selecting appropriate reduction methods is challenging. We report a case of depressed talus fracture concomitant with a pilon fracture, in which retrograde reduction under arthroscopy was performed using the anteromedial approach.

Case presentation

A 43-year-old man sustained a left depressed talus fracture concomitant with a pilon fracture. The depressed lesion was located on the posterolateral part of the talar trochlea, which was inaccessible using standard surgical approaches for pilon fractures. Open reduction and internal fixation were performed using an anteromedial approach, which was also used for arthroscopic-assisted retrograde reduction of the depressed talar fragment.

Conclusions

Reduction for all joint surfaces is required to prevent posttraumatic osteoarthritis. Arthroscopic-assisted retrograde reduction provides good visualization and accurate reduction for a depressed talus fracture. This method is an effective treatment for depressed talus fractures.
