The aim of this study was to examine the results of the acetabular
distraction technique in achieving implantation of a stable construct,
obtaining biological fixation, and producing healing of chronic
pelvic discontinuity at revision total hip arthroplasty. We identified 32 patients treated between 2006 and 2013 who underwent
acetabular revision for a chronic pelvic discontinuity using acetabular
distraction, and who were radiographically evaluated at a mean of
62 months (25 to 160). Of these patients, 28 (87.5%) were female.
The mean age at the time of revision was 67 years (44 to 86). The patients
represented a continuous series drawn from two institutions that
adhered to an identical operative technique.Aims
Patients and Methods
We are currently facing an epidemic of periprosthetic
fractures around the hip. They may occur either during surgery or
post-operatively. Although the acetabulum may be involved, the femur
is most commonly affected. We are being presented with new, difficult
fracture patterns around cemented and cementless implants, and we
face the challenge of an elderly population who may have grossly
deficient bone and may struggle to rehabilitate after such injuries.
The correct surgical management of these fractures is challenging.
This article will review the current choices of implants and techniques
available to deal with periprosthetic fractures of the femur. Cite this article:
Acetabular bone loss is a challenging problem
facing the revision total hip replacement surgeon. Reconstruction
of the acetabulum depends on the presence of anterosuperior and
posteroinferior pelvic column support for component fixation and
stability. The Paprosky classification is most commonly used when
determining the location and degree of acetabular bone loss. Augments
serve the function of either providing primary construct stability
or supplementary fixation. When a pelvic discontinuity is encountered we advocate the use
of an acetabular distraction technique with a jumbo cup and modular
porous metal acetabular augments for the treatment of severe acetabular
bone loss and associated chronic pelvic discontinuity. Cite this article:
