Ankle joint reconstruction by circular frame external fixator for a severely comminuted and contaminated open tibial...

A severely comminuted and contaminated open tibial pilon fracture is one of the most challenging fractures we face. Although nowadays conducting multiple operations over various stages is a common treatment option taking into account the possibility of soft tissue damage, a gold standard protocol for severe pilon fractures has not yet been established. This case concerns a 56-year-old gentleman who suffered a severely comminuted and contaminated Gustilo 3b open tibial pilon fracture (AO 43C3.3) that was successfully treated using a circular frame external fixator without flap. Two years six months after the injury, there were no indications of any skin conditions at the site of the open wound, the range of ankle motion had been maintained and independent walking was possible. The score under the JSSF (Japanese Society of Surgery of the foot) ankle/hind foot scale was 81. This indicates that use of a circular frame external fixator is a useful treatment method in the event of a severe open pilon fracture where there is a large osteochondral bone defect.
