  • Title: Intramedullary total femoral replacement for salvage of the compromised femur associated with hip and knee arthroplasty.
    Author: Peters CL, Hickman JM, Erickson J, Lombardi AV, Berend KR, Mallory TH.
    Journal: J Arthroplasty; 2006 Jan; 21(1):53-8. PubMed ID: 16446185.
    Abstract:
    Severely compromised femora because of prosthetic loosening, osteolysis, or periprosthetic fracture around total hip and knee arthroplasties are increasing. Two approaches that create an intramedullary total femoral (IMTF) replacement are reported. Twenty-three IMTF replacements in 22 patients were performed at 2 institutions. Seven revision total knee arthroplasties with a stemmed component were linked to a well-fixed hip stem with a custom intramedullary sleeve. Sixteen IMTF replacements involved revision of both hip and knee arthroplasties which were connected via an intercalary segment with morse taper junctions. Follow-up averaged 36 months. Complications included 2 dislocations, 2 deep infections, and 2 knee revisions for tibial loosening. Advantages over conventional total femoral replacement or ORIF include less dissection, maintenance of soft tissue attachments, and immediate component stability to allow for early mobilization.
