Primary total talus arthroplasty for Hawkins type IV talar neck fracture dislocation

A woman in her 40s was involved in a motor vehicle collision and sustained a closed Hawkins type IV talar neck fracture dislocation. The injury was treated with reduction, percutaneous pinning and spanning external fixation, followed by definitive treatment with total talus arthroplasty (TTA) 2 months following injury. This is a unique example of definitive management for a severe talar neck fracture dislocation with arthroplasty in the subacute setting. TTA is perhaps a primary option for these injuries at high risk for avascular necrosis, non-union, malunion and post-traumatic arthritis.
