The common recommended treatment for infected
total hip replacement is two-staged exchange including removal of
all components. However, removal of well-fixed femoral stems can
result in structural bone damage. We recently reported on an alternative
treatment of partial two-stage exchange used in selected cases,
in which a well-fixed femoral stem was left and only the acetabular
component removed, the joint space was debrided thoroughly, an antibiotic-laden
polymethylmethacrylate spacer was moulded using a bulb-type syringe
and placed in the acetabulum, intravenous antibiotics were administered
during the interval, and delayed re-implantation was performed.
In 19 patients treated with this technique from January 2000 to
January 2011, 89% were free of infection at a mean follow-up of
four years (2 to 11). Since then, disposable silicone moulds have
become available to fabricate spacers in separate femoral and head
units. The head spacer mould, which incorporates various neck taper adapter
options, greatly facilitates the technique of partial two-stage
exchange. We report our early experience using disposable silicone
head spacer moulds for partial two-stage exchange in seven patients
with infected primary hip replacements. Cite this article:
The August 2014 Wrist &
Hand Roundup360 looks at: Trapeziectomy superior to arthrodesis;
Periprosthetic joint infection (PJI) complicates
between 0.5% and 1.2% primary total hip arthroplasties (THAs) and
may have devastating consequences. The traditional assessment of
patients suffering from PJI has involved the serological study of
inflammatory markers and microbiological analysis of samples obtained
from the joint space. Treatment has involved debridement and revision
arthroplasty performed in either one or two stages. We present an update on the burden of PJI, strategies for its
diagnosis and treatment, the challenge of resistant organisms and
the need for definitive evidence to guide the treatment of PJI after
THA. Cite this article:
The December 2015 Shoulder &

The October 2015 Foot &
Ankle Roundup360 looks at: TightRope in Weber C fractures; A second look at the TightRope; Incisional VAC comes of age?; Platelet-derived growth factor and ankle fusions; Achilles tendon rehab in the longer term following surgery; Telemedicine for diabetic foot ulcer
The primary aim of this study was to investigate the effect of
an enhanced recovery program (ERP) on the short-term functional
outcome after total hip arthroplasty (THA). Secondary outcomes included
its effect on rates of dislocation and mortality. Data were gathered on 1161 patients undergoing primary THA which
included 611 patients treated with traditional rehabilitation and
550 treated with an ERP. Aims
Patients and Methods
The October 2015 Shoulder &
Elbow Roundup360 looks at: Culture time important in propionibacterium acnes; Microvascularisation of the cuff footprint; Degenerative cuff tears: evidence for repair; Middle ground in distal humeral fractures?; Haste needed in elbow heterotopic ossification; Iatrogenic frozen shoulder; Salvage of failed humeral fixation
The aim of this study was to present data on 11 459 patients
who underwent total hip (THA), total knee (TKA) or unicompartmental
knee arthroplasty (UKA) between November 2002 and April 2014 with
aspirin as the primary agent for pharmacological thromboprophylaxis. We analysed the incidence of deep vein thrombosis (DVT) and pulmonary
embolism (PE) then compared the 90-day all-cause mortality with
the corresponding data in the National Joint Registry for England
and Wales (NJR). Aims
Patients and Methods
Two-stage exchange remains the gold standard
for treatment of peri-prosthetic joint infection after total hip replacement
(THR). In the first stage, all components and associated cement
if present are removed, an aggressive debridement is undertaken
including a complete synovectomy, and an antibiotic-loaded cement
spacer is put in place. Patients are then treated with six weeks
of parenteral antibiotics, followed by an ‘antibiotic free period’
to help ensure the infection has been eradicated. If the clinical
evaluation and serum inflammatory markers suggest the infection
has resolved, then the second stage can be completed, which involves
removal of the cement spacer, repeat debridement, and placement
of a new THR. Cite this article:
