There were three major talar fragments including an intermediate anteromedial displaced articular, head, and body (Fig. 1).

Then, conversion to a minimally invasive approach from anteromedial portal (about 4cm) was performed, allowing to directly maintain the reduction of the intermediate articular fragment, confirm a stepof inferior to 1mm, debride synovium, and remove small articular fragments (Fig. 2).

Finally, other two 4.0mm cannulated partial threatened screws (Stryker) were used to complete the fixation (Fig. 3).
Anteroposterior and lateral radiographs from 6-week follow-up demonstrating maintenance of hardware placement, no displacement of the fracture, and Hawkins sign. Computed tomography showing articular congruity and fracture healing.

No degenerative changes of subtalar or talonavicular joints were observed on radiographs at 6-month follow-up (Fig. 4).
