To determine the incidence and timing of post-operative fevers
following shoulder arthroplasty and the resulting investigations
performed. A retrospective review was conducted of all patients undergoing
shoulder arthroplasty over a nine-year period. The charts of all
patients with a post-operative fever (≥ 38.6°C) were reviewed and
the results of all investigations were analysed.Aims

To examine the rates of hamstring graft salvage with arthroscopic
debridement of infected anterior cruciate ligament (ACL) reconstruction
as reported in the literature and discuss functional outcomes. A search was performed without language restriction on PubMed,
EMBASE, Ovid, CINAHL and Cochrane Register of Controlled Trials
(CENTRAL) databases from their inception to April 2015. We identified
147 infected hamstring grafts across 16 included studies. Meta-analysis
was performed using a random-effects model to estimate the overall
graft salvage rate, incorporating two different definitions of graft
salvage.Aims

Diabetes mellitus is the most common co-morbidity associated
with necrotising fasciitis. This study aims to compare the clinical
presentation, investigations, Laboratory Risk Indicator for Necrotising
Fasciitis (LRINEC) score, microbiology and outcome of management
of this condition in diabetic and non-diabetic patients. The medical records of all patients with surgically proven necrotising
fasciitis treated at our institution between 2005 and 2014 were
reviewed. Diagnosis of necrotising fasciitis was made on findings
of ‘dishwater’ fluid, presence of greyish necrotic deep fascia and
lack of bleeding on muscle dissection found intra-operatively. Information
on patients’ demographics, presenting symptoms, clinical signs,
investigations, treatment and outcome were recorded and analysed.Aims

The aims of the study were to review and analyse the reported
series of debridement, antibiotics and implant retention (DAIR)
in the management of infected total hip arthroplasties (THAs) to
establish the overall success and the influencing factors. Using a standardised recognised study protocol, meta-analysis
of observational studies in epidemiology guidelines, a comprehensive
review and analysis of the literature was performed. The primary
outcome measure was the success of treatment. The search strategy
and inclusion criteria which involved an assessment of quality yielded
39 articles for analysis, which included 1296 patients.Aims

A successful outcome following treatment of nonunion requires the correct identification of all of the underlying cause(s) and addressing them appropriately. The aim of this study was to assess the distribution and frequency of causative factors in a consecutive cohort of nonunion patients in order to optimise the management strategy for individual patients presenting with nonunion. Causes of the nonunion were divided into four categories: mechanical; infection; dead bone with a gap; and host. Prospective and retrospective data of 100 consecutive patients who had undergone surgery for long bone fracture nonunion were analysed.Objectives
Methods
As well as debridement and irrigation, soft-tissue coverage, and osseous stabilization, systemic antibiotic prophylaxis is considered the benchmark in the management of open fractures and considerably reduces the risk of subsequent fracture-related infections (FRI). The direct application of antibiotics in the surgical field (local antibiotics) has been used for decades as additional prophylaxis in open fractures, although definitive evidence confirming a beneficial effect is scarce. The purpose of the present study was to review the clinical evidence regarding the effect of prophylactic application of local antibiotics in open limb fractures. A comprehensive literature search was performed in PubMed, Web of Science, and Embase. Cohort studies investigating the effect of additional local antibiotic prophylaxis compared with systemic prophylaxis alone in the management of open fractures were included and the data were pooled in a meta-analysis.Objectives

Deep bone and joint infections (DBJI) are directly intertwined with health, demographic change towards an elderly population, and wellbeing. The elderly human population is more prone to acquire infections, and the consequences such as pain, reduced quality of life, morbidity, absence from work and premature retirement due to disability place significant burdens on already strained healthcare systems and societal budgets. DBJIs are less responsive to systemic antibiotics because of poor vascular perfusion in necrotic bone, large bone defects and persistent biofilm-based infection. Emerging bacterial resistance poses a major threat and new innovative treatment modalities are urgently needed to curb its current trajectory. We present a new biphasic ceramic bone substitute consisting of hydroxyapatite and calcium sulphate for local antibiotic delivery in combination with bone regeneration. Gentamicin release was measured in four setups: 1) Objectives

Many aspects of the surgical treatment of patients with tuberculosis
(TB) of the spine, including the use of instrumentation and the
types of graft, remain controversial. Our aim was to report the
outcome of a single-stage posterior procedure, with or without posterior
decompression, in this group of patients. Between 2001 and 2010, 51 patients with a mean age of 62.5 years
(39 to 86) underwent long posterior instrumentation and short posterior
or posterolateral fusion for TB of the thoracic and lumbar spines,
followed by anti-TB chemotherapy for 12 months. No anterior debridement
of the necrotic tissue was undertaken. Posterior decompression with
laminectomy was carried out for the 30 patients with a neurological
deficit.Aim

High-intensity narrow-spectrum (HINS) light is
a novel violet-blue light inactivation technology which kills bacteria through
a photodynamic process, and has been shown to have bactericidal
activity against a wide range of species. Specimens from patients
with infected hip and knee arthroplasties were collected over a
one-year period (1 May 2009 to 30 April 2010). A range of these
microbial isolates were tested for sensitivity to HINS-light. During
testing, suspensions of the pathogens were exposed to increasing
doses of HINS-light (of 123mW/cm2 irradiance). Non-light exposed
control samples were also used. The samples were then plated onto
agar plates and incubated at 37°C for 24 hours before enumeration.
Complete inactivation (greater than 4-log10 reduction)
was achieved for all of the isolates. The typical inactivation curve
showed a slow initial reaction followed by a rapid period of inactivation.
The doses of HINS-light required ranged between 118 and 2214 J/cm2.
Gram-positive bacteria were generally found to be more susceptible
than Gram-negative. As HINS-light uses visible wavelengths, it can be safely used
in the presence of patients and staff. This unique feature could
lead to its possible use in the prevention of infection during surgery
and post-operative dressing changes. Cite this article:
In the initial development of total shoulder arthroplasty (TSA),
the humeral component was usually fixed with cement. Cementless
components were subsequently introduced. The aim of this study was
to compare the long-term outcome of cemented and cementless humeral
components in arthroplasty of the shoulder. All patients who underwent primary arthroplasty of the shoulder
at our institution between 1970 and 2012 were included in the study.
There were 4636 patients with 1167 cemented humeral components and
3469 cementless components. Patients with the two types of fixation
were matched for nine different covariates using a propensity score
analysis. A total of 551 well-balanced pairs of patients with cemented
and cementless components were available after matching for comparison
of the outcomes. The clinical outcomes which were analysed included loosening
of the humeral component determined at revision surgery, periprosthetic
fractures, post-operative infection and operating time.Aims

We compared the use of broth culture medium for
samples taken in theatre with the standard practice of placing tissue
samples in universal containers. A total of 67 consecutive patients
had standard multiple samples of deep tissue harvested at surgery
and distributed equally in theatre either to standard universal
containers or to broth culture medium. These samples were cultured
by direct and enrichment methods. The addition of broth in theatre to
standard practice led to an increase in sensitivity from 83% to
95% and an increase in negative predictive value from 77% to 91%.
Placing tissue samples directly into broth in the operating theatre
is a simple, inexpensive way to increase the sensitivity of cultures
from infected patients, and does not appear to compromise the specificity
of these cultures. Cite this article:
The objective of this study was to develop a test for the rapid (within 25 minutes) intraoperative detection of bacteria from synovial fluid to diagnose periprosthetic joint infection (PJI). The 16s rDNA test combines a polymerase chain reaction (PCR) for amplification of 16s rDNA with a lateral flow immunoassay in one fully automated system. The synovial fluid of 77 patients undergoing joint aspiration or primary or revision total hip or knee surgery was prospectively collected. The cohort was divided into a proof-of-principle cohort (n = 17) and a validation cohort (n = 60). Using the proof-of-principle cohort, an optimal cut-off for the discrimination between PJI and non-PJI samples was determined. PJI was defined as detection of the same bacterial species in a minimum of two microbiological samples, positive histology, and presence of a sinus tract or intra-articular pus.Objectives

Following the introduction of national standards in 2009, most
major paediatric trauma is now triaged to specialist units offering
combined orthopaedic and plastic surgical expertise. We investigated
the management of open tibia fractures at a paediatric trauma centre,
primarily reporting the risk of infection and rate of union. A retrospective review was performed on 61 children who between
2007 and 2015 presented with an open tibia fracture. Their mean
age was nine years (2 to 16) and the median follow-up was ten months
(interquartile range 5 to 18). Management involved IV antibiotics,
early debridement and combined treatment of the skeletal and soft-tissue injuries
in line with standards proposed by the British Orthopaedic Association.Aims

The aim of this paper was to present the clinical features of
patients with musculoskeletal sources of methicillin-sensitive A total of 137 patients presented with MSSA septicaemia between
2012 and 2015. The primary source of infection was musculoskeletal
in 48 patients (35%). Musculoskeletal infection was considered the
primary source of septicaemia when endocarditis and other obvious
sources were excluded. All patients with an arthroplasty at the time
were evaluated for any prosthetic involvement. Aims

Induced membrane technique is a relatively new technique in the reconstruction of large bone defects. It involves the implantation of polymethylmethacrylate (PMMA) cement in the bone defects to induce the formation of membranes after radical debridement and reconstruction of bone defects using an autologous cancellous bone graft in a span of four to eight weeks. The purpose of this study was to explore the clinical outcomes of the induced membrane technique for the treatment of post-traumatic osteomyelitis in 32 patients. A total of 32 cases of post-traumatic osteomyelitis were admitted to our department between August 2011 and October 2012. This retrospective study included 22 men and ten women, with a mean age of 40 years (19 to 70). Within this group there were 20 tibias and 12 femurs with a mean defect of 5 cm (1.5 to 12.5). Antibiotic-loaded PMMA cement was inserted into the defects after radical debridement. After approximately eight weeks, the defects were implanted with bone graft.Objectives

Whether patients with asymptomatic bacteriuria
should be investigated and treated before elective hip and knee replacement
is controversial, although it is a widespread practice. We conducted
a prospective observational cohort study with urine analyses before
surgery and three days post-operatively. Patients with symptomatic
urinary infections or an indwelling catheter were excluded. Post-discharge
surveillance included questionnaires to patients and general practitioners
at three months. Among 510 patients (309 women and 201 men), with
a median age of 69 years (16 to 97) undergoing lower limb joint
replacements (290 hips and 220 knees), 182 (36%) had pre-operative asymptomatic
bacteriuria, mostly due to We conclude that testing and treating asymptomatic urinary tract
colonisation before joint replacement is unnecessary. Cite this article:
