The mainstay of surgical correction of hallux valgus is first
metatarsal osteotomy, either proximally or distally. We present
a technique of combining a distal chevron osteotomy with a proximal
opening wedge osteotomy, for the correction of moderate to severe
hallux valgus. We reviewed 45 patients (49 feet) who had undergone double osteotomy.
Outcome was assessed using the American Orthopaedic Foot and Ankle
Society (AOFAS) and the Short Form (SF) -36 Health Survey scores.
Radiological measurements were undertaken to assess the correction. The mean age of the patients was 60.8 years (44.2 to 75.3). The
mean follow-up was 35.4 months (24 to 51).Aims
Patients and Methods
The rate of surgical site infection after elective
foot and ankle surgery is higher than that after other elective orthopaedic
procedures. Since December 2005, we have prospectively collected data on
the rate of post-operative infection for 1737 patients who have
undergone elective foot and ankle surgery. In March 2008, additional
infection control policies, focused on surgical and environmental
risk factors, were introduced in our department. We saw a 50% reduction in the rate of surgical site infection
after the introduction of these measures. We are, however, aware
that the observed decrease may not be entirely attributable to these
measures alone given the number of factors that predispose to post-operative
wound infection. Cite this article:
We wished to examine the effectiveness of tibial lengthening
using a two ring Ilizarov frame in skeletally immature patients.
This is a potentially biomechanically unstable construct which risks
the loss of axial control. We retrospectively reviewed a consecutive series of 24 boys and
26 girls, with a mean age of 8.6 years (4 to 14), who underwent
52 tibial lengthening procedures with a mean follow-up of 4.3 years
(4.0 to 16.9). Tibial alignment was measured before and after treatment
using joint orientation lines from the knee and a calculation of
the oblique plane axis.Aims
Patients and Methods
Obesity is a worldwide epidemic that has both
economic and health implications of enormous consequence. The obese
patients tend to have earlier symptoms related to osteoarthritis,
more peri-operative medical problems, higher rates of infection
and more technical difficulties intra-operatively following hip
and knee arthroplasty. Nevertheless, these patients have good long-term
clinical outcomes and implant survival rates and are often some of
the most satisfied patients after joint arthroplasty. Therefore,
obese patients should not be denied surgery based on their weight
alone. Cite this article:
The biomembrane (induced membrane) formed around polymethylmethacrylate (PMMA) spacers has value in clinical applications for bone defect reconstruction. Few studies have evaluated its cellular, molecular or stem cell features. Our objective was to characterise induced membrane morphology, molecular features and osteogenic stem cell characteristics. Following Institutional Review Board approval, biomembrane specimens were obtained from 12 patient surgeries for management of segmental bony defects (mean patient age 40.7 years, standard deviation 14.4). Biomembranes from nine tibias and three femurs were processed for morphologic, molecular or stem cell analyses. Gene expression was determined using the Affymetrix GeneChip Operating Software (GCOS). Molecular analyses compared biomembrane gene expression patterns with a mineralising osteoblast culture, and gene expression in specimens with longer spacer duration (> 12 weeks) with specimens with shorter durations. Statistical analyses used the unpaired student Objectives
Methods
Our aim was to investigate the outcomes of patients with a displaced
fracture of the glenoid fossa who are treated conservatively. There
is little information in the literature about the treatment of these
rare injuries non-operatively. We reviewed 24 patients with a mean age of 52 years (19 to 81)
at a mean of 5.6 years (11 months to 18 years) after the injury.Aims
Patients and Methods
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

Revision total elbow arthroplasty (TEA) is often challenging.
The aim of this study was to report on the clinical and radiological
results of revision arthroplasty of the elbow with the Latitude
TEA. Between 2006 and 2010 we used the Latitude TEA for revision in
18 consecutive elbows (17 patients); mean age 53 years (28 to 80);
14 women. A Kudo TEA was revised in 15 elbows and a Souter-Strathclyde
TEA in three. Stability, range of movement (ROM), visual analogue score (VAS)
for pain and functional scores, Elbow Functional Assessment Scale
(EFAS), the Functional Rating Index of Broberg and Morrey (FRIBM)
and the Modified Andrews’ Elbow Scoring System (MAESS) were assessed
pre-operatively and at each post-operative follow-up visit (six,
12 months and biennially thereafter). Radiographs were analysed
for loosening, fractures and dislocation. The mean follow-up was
59 months (26 to 89).Aims
Patients and Methods
We wanted to investigate regional variations in the organisms
reported to be causing peri-prosthetic infections and to report
on prophylaxis regimens currently in use across England. Analysis of data routinely collected by Public Health England’s
(PHE) national surgical site infection database on elective primary
hip and knee arthroplasty procedures between April 2010 and March
2013 to investigate regional variations in causative organisms.
A separate national survey of 145 hospital Trusts (groups of hospitals
under local management) in England routinely performing primary
hip and/or knee arthroplasty was carried out by standard email questionnaire.Objectives
Methods
We wished to quantify the extent of soft-tissue damage sustained
during minimally invasive total hip arthroplasty through the direct
anterior (DA) and direct superior (DS) approaches. In eight cadavers, the DA approach was performed on one side,
and the DS approach on the other, a single brand of uncemented hip
prosthesis was implanted by two surgeons, considered expert in their
surgical approaches. Subsequent reflection of the gluteus maximus
allowed the extent of muscle and tendon damage to be measured and
the percentage damage to each anatomical structure to be calculated.Aims
Materials and Methods
Bactericidal levels of antibiotics are difficult
to achieve in infected total joint arthroplasty when intravenous antibiotics
or antibiotic-loaded cement spacers are used, but intra-articular
(IA) delivery of antibiotics has been effective in several studies.
This paper describes a protocol for IA delivery of antibiotics in
infected knee arthroplasty, and summarises the results of a pharmacokinetic
study and two clinical follow-up studies of especially difficult
groups: methicillin-resistant Cite this article:
We have investigated the effect of using tranexamic
acid (TXA) during peri-acetabular osteotomy (PAO) on peri-operative
blood loss and blood transfusion requirements. In addition we analysed
whether the use of TXA was associated with an increased risk of
venous thromboembolism (VTE) following this procedure. A consecutive series of 96 PAOs, performed by a single surgeon,
were reviewed. A total of 48 patients received TXA and 48 did not.
The TXA group received a continuous infusion of TXA at a rate of
10 mg/kg/h. The primary outcome measure was the requirement for
blood transfusion. Secondary outcomes included total blood loss,
the decrease in the level of haemoglobin in the blood, the length
of hospital stay, and the complications of this treatment. The mean rate of transfusion was significantly lower in the TXA
group (62.5% The use of TXA reduced the blood loss and the rate of transfusion
after PAO significantly, without adverse effects such as an increased
rate of VTE. Cite this article:
In this retrospective observational cohort study,
we describe 17 patients out of 1775 treated for various fractures who
developed mycobacterium tuberculosis (MTB) infection after surgery.
The cohort comprised 15 men and two women with a mean age of 40
years (24 to 70). A total of ten fractures were open and seven were
closed. Of these, seven patients underwent intramedullary nailing
of a fracture of the long bone, seven had fractures fixed with plates,
two with Kirschner-wires and screws, and one had a hemiarthroplasty
of the hip with an Austin Moore prosthesis. All patients were followed-up
for two years. In all patients, the infection resolved, and in 14
the fractures united. Nonunion was seen in two patients one of whom
underwent two-stage total hip arthroplasty (THA) and the other patient
was treated using excision arthoplasty. Another patient was treated
using two-stage THA. With only sporadic case reports in the literature,
MTB infection is rarely clinically suspected, even in underdeveloped
and developing countries, where pulmonary and other forms of TB
are endemic. In developed countries there is also an increased incidence
among immunocompromised patients. In this paper we discuss the pathogenesis
and incidence of MTB infection after surgical management of fractures
and suggest protocols for early diagnosis and management. Cite this article:
External fixation is widely used in orthopaedic
and trauma surgery. Infections around pin or wire sites, which are usually
localised, non-invasive, and are easily managed, are common. Occasionally,
more serious invasive complications such as necrotising fasciitis
(NF) and toxic shock syndrome (TSS) may occur. We retrospectively reviewed all patients who underwent external
fixation between 1997 and 2012 in our limb lengthening and reconstruction
programme. A total of eight patients (seven female and one male)
with a mean age of 20 years (5 to 45) in which pin/wire track infections
became limb- or life-threatening were identified. Of these, four
were due to TSS and four to NF. Their management is described. A
satisfactory outcome was obtained with early diagnosis and aggressive
medical and surgical treatment. Clinicians caring for patients who have external fixation and
in whom infection has developed should be aware of the possibility
of these more serious complications. Early diagnosis and aggressive
treatment are required in order to obtain a satisfactory outcome. Cite this article:
