title: A custom coupling device of total knee and ipsilateral total hip arthroplasties after distal femoral fracture.
abstract: The treatment of periprosthetic femoral fractures around long-stemmed hip implants is an orthopedic challenge, which may be complicated by the presence or need for a total knee arthroplasty. Treatment of this fracture when the proximal implant is well fixed and a distal implant is required poses ongoing challenges. Traditional plating and allograft struts have produced variable results, particularly in osteoporotic bone, where incidence of nonunion is greater. Thus, we report a custom interlocking device, which couples the stem of the fixed proximal implant to a new stemmed total knee prosthesis, resulting in the expedited restoration of functionality and fracture union.
