Staged treatment of high energy midfoot fracture dislocations

Abstract

Background: Staged care with interval external fixation is a successful established treatment strategy for high energy periarticular fractures with often extensive soft tissue damage such as the tibial plateau and plafond. The aim of the current study was to determine whether staged care of high energy midfoot fracture/dislocation with interval external fixation prior to definitive open reconstruction in the polytraumatized patient was both safe and efficacious.

Methods: One hundred twenty-three patients were operated on for high energy midfoot fracture/dislocation during the 8-year study period. Eighteen polytrauma patients were selectively treated with a staged protocol. Radiographic assessment was utilized to determine if the fixator achieved gross skeletal alignment. Further, final alignment after definitive reconstruction and postoperative complications were analyzed.

Results: The fixator improved both length and alignment of all high energy midfoot fracture/dislocations. Loss of acceptable reduction while in the temporary frame occurred in only 1 case. Final alignment after definitive reconstruction was anatomic in all cases. No cases of wound-related complication and/or deep infection occurred.

Conclusion: Delayed reconstruction of high energy midfoot fracture/dislocation using interval external fixation should be an accepted care paradigm in selected polytrauma patients.

Level of evidence: Level III, retrospective comparative study.
