Periprosthetic joint infection (PJI) is a devastating
complication for patients and results in greatly increased costs
of care for both healthcare providers and patients. More than 15
500 revision hip and knee procedures were recorded in England, Wales
and Northern Ireland in 2013, with infection accounting for 13%
of revision hip and 23% of revision knee procedures. We report our experience of using antibiotic eluting absorbable
calcium sulphate beads in 15 patients (eight men and seven women
with a mean age of 64.8 years; 41 to 83) as part of a treatment
protocol for PJI in revision arthroplasty. The mean follow-up was 16 months (12 to 22). We report the outcomes
and complications, highlighting the risk of hypercalcaemia which
occurred in three patients. We recommend that serum levels of calcium be routinely sought
following the implantation of absorbable calcium sulphate beads
in orthopaedic surgery. Cite this article:
We undertook a prospective non-randomised radiological study
to evaluate the preliminary results of using magnetically-controlled
growing rods (MAGEC System, Ellipse technology) to treat children
with early-onset scoliosis. Between January 2011 and January 2015, 19 children were treated
with magnetically-controlled growing rods (MCGRs) and underwent
distraction at three-monthly intervals. The mean age of our cohort
was 9.1 years (4 to 14) and the mean follow-up 22.4 months (5.1
to 35.2). Of the 19 children, eight underwent conversion from traditional growing
rods. Whole spine radiographs were carried out pre- and post-operatively:
image intensification was used during each lengthening in the outpatient
department. The measurements evaluated were Cobb angle, thoracic kyphosis,
proximal junctional kyphosis and spinal growth from T1 to S1.Aims
Patients and Methods
Prophylactic antibiotics can decrease the risk
of wound infection and have been routinely employed in orthopaedic surgery
for decades. Despite their widespread use, questions still surround
the selection of antibiotics for prophylaxis, timing and duration
of administration. The health economic costs associated with wound
infections are significant, and the judicious but appropriate use
of antibiotics can reduce this risk. This review examines the evidence behind commonly debated topics
in antibiotic prophylaxis and highlights the uses and advantages
of some commonly used antibiotics. Cite this article:
The global economy has been facing a financial crisis. Healthcare costs are spiraling, and there is a projected £30 billion health funding gap by 2020 in the UK. What is happening in the UK is a reflection of a global problem. Rationing of healthcare is a topic of much discussion; as unless spending is capped, providing healthcare will become unsustainable. Who decides how money is spent, and which services should be rationed? In this article we aim to discuss the impact that rationing may have on orthopaedic surgery, and we will discuss our own experiences of attempts to ration local services.
An important measure for the diagnosis and monitoring of knee osteoarthritis is the minimum joint space width (mJSW). This requires accurate alignment of the x-ray beam with the tibial plateau, which may not be accomplished in practice. We investigate the feasibility of a new mJSW measurement method from stereo radiographs using 3D statistical shape models (SSM) and evaluate its sensitivity to changes in the mJSW and its robustness to variations in patient positioning and bone geometry. A validation study was performed using five cadaver specimens. The actual mJSW was varied and images were acquired with variation in the cadaver positioning. For comparison purposes, the mJSW was also assessed from plain radiographs. To study the influence of SSM model accuracy, the 3D mJSW measurement was repeated with models from the actual bones, obtained from CT scans.Objectives

We conducted a randomised controlled trial to assess the accuracy
of positioning and alignment of the components in total knee arthroplasty
(TKA), comparing those undertaken using standard intramedullary
cutting jigs and those with patient-specific instruments (PSI). There were 64 TKAs in the standard group and 69 in the PSI group. The post-operative hip-knee-ankle (HKA) angle and positioning
was investigated using CT scans. Deviation of >
3° from the planned
position was regarded as an outlier. The operating time, Oxford
Knee Scores (OKS) and Short Form-12 (SF-12) scores were recorded.Aims

Tranexamic acid (TXA) is an antifibrinolytic agent used as a blood-sparing technique in total knee arthroplasty (TKA), and is routinely administered by intravenous (IV) or intra-articular (IA) injection. Recently, a novel method of TXA administration, the combined IV and IA application of TXA, has been applied in TKA. However, the scientific evidence of combined administration of TXA in TKA is still meagre. This meta-analysis aimed to investigate the efficacy and safety of combined IV and IA TXA in patients undergoing TKA. A systematic search was carried out in PubMed, the Cochrane Clinical Trial Register (Issue12 2015), Embase, Web of Science and the Chinese Biomedical Database. Only randomised controlled trials (RCT) evaluating the efficacy and safety of combined use TXA in TKA were identified. Two authors independently identified the eligible studies, extracted data and assessed the methodological quality of included studies. Meta-analysis was conducted using Review Manager 5.3 software.Objectives

We present a review of litigation claims relating
to foot and ankle surgery in the NHS in England during the 17-year period
between 1995 and 2012. A freedom of information request was made to obtain data from
the NHS litigation authority (NHSLA) relating to orthopaedic claims,
and the foot and ankle claims were reviewed. During this period of time, a total of 10 273 orthopaedic claims
were made, of which 1294 (12.6%) were related to the foot and ankle.
1036 were closed, which comprised of 1104 specific complaints. Analysis
was performed using the complaints as the denominator. The cost
of settling these claims was more than £36 million. There were 372 complaints (33.7%) involving the ankle, of which
273 (73.4%) were related to trauma. Conditions affecting the first
ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective
practice. Overall, claims due to diagnostic errors accounted for
210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery
and 149 (13.5%) from alleged mismanagement. Our findings show that the incorrect, delayed or missed diagnosis
of conditions affecting the foot and ankle is a key area for improvement,
especially in trauma practice. Cite this article:
The molecular mechanism of rheumatoid arthritis (RA) remains elusive. We conducted a protein-protein interaction network-based integrative analysis of genome-wide association studies (GWAS) and gene expression profiles of RA. We first performed a dense search of RA-associated gene modules by integrating a large GWAS meta-analysis dataset (containing 5539 RA patients and 20 169 healthy controls), protein interaction network and gene expression profiles of RA synovium and peripheral blood mononuclear cells (PBMCs). Gene ontology (GO) enrichment analysis was conducted by DAVID. The protein association networks of gene modules were generated by STRING.Objectives

Hip fracture is a common injury associated with
high mortality, long-term disability and huge socio-economic burden.
Yet there has been relatively little research into best treatment,
and evidence that has been generated has often been criticised for
its poor quality. Here, we discuss the advances made towards overcoming
these criticisms and the future directions for hip fracture research:
how co-ordinating existing national infrastructures and use of now
established clinical research networks will likely go some way towards
overcoming the practical and financial challenges of conducting
large trials. We highlight the importance of large collaborative
pragmatic trials to inform decision/policy makers and the progress
made towards reaching a consensus on a core outcome set to facilitate data
pooling for evidence synthesis and meta-analysis. These advances and future directions are a priority in order
to establish the high-quality evidence base required for this important
group of patients. Cite this article:

We examined risk of developing acute renal failure and the associated
mortality among patients aged >
65 years undergoing surgery for
a fracture of the hip. We used medical databases to identify patients who underwent
surgical treatment for a fracture of the hip in Northern Denmark
between 2005 and 2011. Acute renal failure was classified as stage
1, 2 and 3 according to the Kidney Disease Improving Global Outcome
criteria. We computed the risk of developing acute renal failure
within five days after surgery with death as a competing risk, and
the short-term (six to 30 days post-operatively) and long-term mortality
(31 days to 365 days post-operatively). We calculated adjusted hazard
ratios (HRs) for death with 95% confidence intervals (CIs).Aims

Identifying cervical spine injuries in confused or comatose patients
with multiple injuries provides a diagnostic challenge. Our aim
was to investigate the protocols which are used for the clearance
of the cervical spine in these patients in English hospitals. All hospitals in England with an Emergency Department were asked
about the protocols which they use for assessing the cervical spine.
All 22 Major Trauma Centres (MTCs) and 141 of 156 non-MTCs responded
(response rate 91.5%).Aim

We wished to assess the feasibility of a future randomised controlled
trial of parathyroid hormone (PTH) supplements to aid healing of
trochanteric fractures of the hip, by an open label prospective
feasibility and pilot study with a nested qualitative sub study.
This aimed to inform the design of a future powered study comparing
the functional recovery after trochanteric hip fracture in patients
undergoing standard care, We undertook a pilot study comparing the functional recovery
after trochanteric hip fracture in patients 60 years or older, admitted
with a trochanteric hip fracture, and potentially eligible to be
randomised to either standard care or the administration of subcutaneous
PTH for six weeks. Our desired outcomes were functional testing
and measures to assess the feasibility and acceptability of the
study.Aims

Using a systematic review, we investigated whether there is an
increased risk of post-operative infection in patients who have
received an intra-articular corticosteroid injection to the hip
for osteoarthritis prior to total hip arthroplasty (THA). Studies dealing with an intra-articular corticosteroid injection
to the hip and infection following subsequent THA were identified
from databases for the period between 1990 to 2013. Retrieved articles
were independently assessed for their methodological quality.Aims
