Extract
Revision of a loose femoral stem of a total hip prosthesis in the presence
of massive bone loss and previous infection represents a challenging surgical
reconstruction. Current reconstructive options include the use of a long
prosthetic stem with cemented fixation into a proximal structural allograft,
the use of a custom reconstructive tumor endoprosthesis, or strut allograft
augmentation of the femur with use of a long cementless femoral stem. Previous
infection is a relative contraindication for the use of
allograft1,2,
and allografts are associated with the complications of fracture and
nonunion3. In the
present report, we describe an alternative management option for this complex
femoral reconstruction that includes the use of a long-stemmed
hydroxyapatitecoated implant with distal interlocking screw fixation. Our
patient was informed that data concerning the case would be submitted for
publication.
