The World Health Organization (WHO) and the Centre
for Disease Control and Prevention (CDC) recently published guidelines
for the prevention of surgical site infection. The WHO guidelines,
if implemented worldwide, could have an immense impact on our practices
and those of the CDC have implications for healthcare policy in
the United States. Our aim was to review the strategies for prevention of periprosthetic
joint infection in light of these and other recent guidelines. Cite this article:
To evaluate the hypothesis that failed osteosynthesis of periprosthetic
Vancouver type B1 fractures can be treated successfully with stem
revision using a transfemoral approach and a cementless, modular,
tapered revision stem with reproducible rates of fracture healing,
stability of the revision stem, and clinically good results. A total of 14 patients (11 women, three men) with a mean age
of 72.4 years (65 to 90) undergoing revision hip arthroplasty after
failed osteosynthesis of periprosthetic fractures of Vancouver type
B1 were treated using a transfemoral approach to remove the well-fixed
stem before insertion of a modular, fluted titanium stem which obtained
distal fixation. These patients were clinically and radiologically
followed up for a mean 52.2 months (24 to 144).Aims
Patients and Methods
The aim of this study was to investigate the outcomes of Vancouver
type B2 and B3 fractures by performing a systematic review of the
methods of surgical treatment which have been reported. A systematic search was performed in Ovid MEDLINE, Embase and
the Cochrane Central Register of Controlled Trials. For inclusion,
studies required a minimum of ten patients with a Vancouver type
B2 and/or ten patients with a Vancouver type B3 fracture, a minimum
mean follow-up of two years and outcomes which were matched to the type
of fracture. Studies were also required to report the rate of re-operation
as an outcome measure. The protocol was registered in the PROSPERO
database. Aims
Materials and Methods
Compared with primary total hip arthroplasty (THA), revision
surgery can be challenging. The cement-in-cement femoral revision
technique involves removing a femoral component from a well-fixed
femoral cement mantle and cementing a new stem into the original
mantle. This technique is widely used and when carried out for the
correct indications, is fast, relatively inexpensive and carries
a reduced short-term risk for the patient compared with the alternative
of removing well-fixed cement. We report the outcomes of this procedure
when two commonly used femoral stems are used. We identified 1179 cement-in-cement stem revisions involving
an Exeter or a Lubinus stem reported to the Swedish Hip Arthroplasty
Register (SHAR) between January 1999 and December 2015. Kaplan-Meier
survival analysis was performed.Aims
Patients and Methods
Our first aim was to determine whether there are significant
changes in the level of metal ions in the blood at mid-term follow-up,
in patients with an Articular Surface Replacement (ASR) arthroplasty.
Secondly, we sought to identify risk factors for any increases. The study involved 435 patients who underwent unilateral, metal-on-metal
(MoM) hip resurfacing (HRA) or total hip arthroplasty (THA). These
patients all had one measurement of the level of metal ions in the
blood before seven years had passed post-operatively (early evaluation)
and one after seven years had passed post-operatively (mid-term evaluation).
Changes in ion levels were tested using a Wilcoxon signed-rank test.
We identified subgroups at the highest risk of increase using a
multivariable linear logistic regression model.Aims
Patients and Methods
The aim of this study was to examine the real time A total of 50 patients (83 hips) underwent 4D dynamic CT scanning
of the hip, producing real time osseous models of the pelvis and
femur being moved through flexion, adduction, and internal rotation.
The location and size of the cam deformity and its relationship
to the angle of flexion of the hip and pelvic tilt, and the position
of impingement were recorded.Aims
Patients and Methods
The aim of this study was to compare early functional and health
related quality of life outcomes (HRQoL) in patients who have undergone
total hip arthroplasty (THA) using a bone conserving short stem
femoral component and those in whom a conventional length uncemented
component was used. Outcome was assessed using a validated performance
based outcome instrument as well as patient reported outcome measures
(PROMs). We prospectively analysed 33 patients whose THA involved a contemporary
proximally porous coated tapered short stem femoral component and
53 patients with a standard conventional femoral component, at a
minimum follow-up of two years. The mean follow-up was 31.4 months
(24 to 39). Patients with poor proximal femoral bone quality were
excluded. The mean age of the patients was 66.6 years (59 to 77)
and the mean body mass index was 30.2 kg/m2 (24.1 to
41.0). Outcome was assessed using the Oxford Hip Score (OHS) and
the University College Hospital (UCH) hip score which is a validated
performance based instrument. HRQoL was assessed using the EuroQol
5D (EQ-5D).Aims
