Introduction
|
|---|
Recurrent infection at the site of a total joint replacement
secondary to a highly resistant organism in combination with a periprosthetic
fracture presents a treatment challenge. To salvage this situation, a hip
disarticulation or a type-B-IIIb rotationplasty, as described by Winkelmann,
are the only viable surgical techniques reported in the literature of which we
are
aware1,2.
The purpose of our report is to present an alternative surgical technique for
creating an above-the-knee stump with use of a modular proximal femoral
replacement with a bipolar head after hip disarticulation. The procedure
consists of two stages.
 |
Stage One: Débridement and Implantation of a Cement Spacer
|
|---|
Following implant removal and débridement, an antibiotic-impregnated
polymethylmethacrylate spacer is implanted. After the proximal part of the
femur is removed, the greater trochanter is fixed to the spacer to prevent
shortening of the gluteal muscles. During this first stage, either an
immediate hip disarticulation with reconstruction of an above-the-knee stump
is performed (Case 1) . . . [Full Text of this Article]
