We aimed to determine whether there is evidence of improved patient
outcomes in Major Trauma Centres following the regionalisation of
trauma care in England. An observational study was undertaken using the Trauma Audit
and Research Network (TARN), Hospital Episode Statistics (HES) and
national death registrations. The outcome measures were indicators
of the quality of trauma care, such as treatment by a senior doctor
and clinical outcomes, such as mortality in hospital.Aims
Patients and Methods
Developmental dysplasia of the hip (DDH) should
be diagnosed as early as possible to optimise treatment. The current
United Kingdom recommendations for the selective screening of DDH
include a clinical examination at birth and at six weeks. In Northern
Ireland babies continue to have an assessment by a health visitor
at four months of age. As we continue to see late presentations
of DDH, beyond one year of age, we hypothesised that a proportion had
missed an opportunity for earlier diagnosis. We expect those who
presented to our service with Tonnis grade III or IV hips and decreased
abduction would have had clinical signs at their earlier assessments. We performed a retrospective review of all patients born in Northern
Ireland between 2008 and 2010 who were diagnosed with DDH after
their first birthday. There were 75 856 live births during the study
period of whom 645 children were treated for DDH (8.5 per 1000).
The minimum follow-up of our cohort from birth, to detect late presentation,
was four years and six months. Of these, 32 children (33 hips) were
diagnosed after their first birthday (0.42 per 1000). With optimum application of our selective screening programme
21 (65.6%) of these children had the potential for an earlier diagnosis,
which would have reduced the incidence of late diagnosis to 0.14
per 1000. As we saw a peak in diagnosis between three and five months
our findings support the continuation of the four month health visitor
check. Our study adds further information to the debate regarding

The aim of this study was to review the role
of clinical trial networks in orthopaedic surgery. A total of two
electronic databases (MEDLINE and EMBASE) were searched from inception
to September 2013 with no language restrictions. Articles related
to randomised controlled trials (RCTs), research networks and orthopaedic
research, were identified and reviewed. The usefulness of trainee-led
research collaborations is reported and our knowledge of current
clinical trial infrastructure further supplements the review. Searching
yielded 818 titles and abstracts, of which 12 were suitable for
this review. Results are summarised and presented narratively under
the following headings: 1) identifying clinically relevant research
questions; 2) education and training; 3) conduct of multicentre
RCTs and 4) dissemination and adoption of trial results. This review
confirms growing international awareness of the important role research
networks play in supporting trials in orthopaedic surgery. Multidisciplinary
collaboration and adequate investment in trial infrastructure are crucial
for successful delivery of RCTs. Cite this article:

Patients and Methods
Fractures of the distal femur are an important cause of morbidity.
Their optimal management remains controversial. Contemporary implants
include angular-stable anatomical locking plates and locked intramedullary
nails (IMNs). We compared the long-term patient-reported functional
outcome of fixation of fractures of the distal femur using these
two methods of treatment. A total of 297 patients were retrospectively identified from
a State-wide trauma registry in Australia: 195 had been treated
with a locking plate and 102 with an IMN. Baseline characteristics
of the patients and their fractures were recorded. Health-related
quality-of-life, functional and radiographic outcomes were compared
using mixed effects regression models at six months and one year.Aims
Patients and Methods
The aim of this study was to inform a definitive trial which
could determine the clinical effectiveness of the X-Bolt Dynamic
Hip Plating System compared with the sliding hip screw for patients
with complex pertrochanteric fragility fractures of the femur. This was a single centre, participant blinded, randomised, standard-of-care
controlled pilot trial. Patients aged 60 years and over with AO/ASIF
A2 and A3 type femoral pertrochanteric fractures were eligible.Aims
Patients and Methods
We aimed to identify the pattern of nerve injury associated with
paediatric supracondylar fractures of the humerus. Over a 17 year period, between 1996 and 2012, 166 children were
referred to our specialist peripheral nerve injury unit. From examination
of the medical records and radiographs were recorded the nature
of the fracture, associated vascular and neurological injury, treatment
provided and clinical course.Aims
Patients and Methods
Joint replacement of the hip and knee remain
very satisfactory operations. They are, however, expensive. The
actual manufacturing of the implant represents only 30% of the final
cost, while sales and marketing represent 40%. Recently, the patents
on many well established and successful implants have expired. Companies
have started producing and distributing implants that purport to
replicate existing implants with good long-term results. The aims of this paper are to assess the legality, the monitoring
and cost saving implications of such generic implants. We also assess
how this might affect the traditional orthopaedic implant companies. Cite this article:
Wound complications are reported in up to 10% hip and knee arthroplasties and there is a proven association between wound complications and deep prosthetic infections. In this randomised controlled trial (RCT) we explore the potential benefits of a portable, single use, incisional negative pressure wound therapy dressing (iNPWTd) on wound exudate, length of stay (LOS), wound complications, dressing changes and cost-effectiveness following total hip and knee arthroplasties. A total of 220 patients undergoing elective primary total hip and knee arthroplasties were recruited into in a non-blinded RCT. For the final analysis there were 102 patients in the study group and 107 in the control group.Objectives
Methods
Total joint arthroplasty (TJA) is commonly performed in elderly
patients. Frailty, an aggregate expression of vulnerability, becomes
increasingly common with advanced age, and independently predicts
adverse outcomes and the use of resources after a variety of non-cardiac
surgical procedures. Our aim was to assess the impact of frailty
on outcomes after TJA. We analysed the impact of pre-operative frailty on death and
the use of resources after elective TJA in a population-based cohort
study using linked administrative data from Ontario, Canada.Aims
Patients and Methods
The monitoring of fracture healing is a complex process. Typically, successive radiographs are performed and an emerging calcification of the fracture area is evaluated. The aim of this study was to investigate whether different bone healing patterns can be distinguished using a telemetric instrumented femoral internal plate fixator. An electronic telemetric system was developed to assess bone healing mechanically. The system consists of a telemetry module which is applied to an internal locking plate fixator, an external reader device, a sensor for measuring externally applied load and a laptop computer with processing software. By correlation between externally applied load and load measured in the implant, the elasticity of the osteosynthesis is calculated. The elasticity decreases with ongoing consolidation of a fracture or nonunion and is an appropriate parameter for the course of bone healing. At our centre, clinical application has been performed in 56 patients suffering nonunion or fracture of the femur.Objectives
Materials and Methods
Hip arthroscopy in the setting of hip dysplasia is controversial in the orthopaedic community, as the outcome literature has been variable and inconclusive. We hypothesise that outcomes of hip arthroscopy may be diminished in the setting of hip dysplasia, but outcomes may be acceptable in milder or borderline cases of hip dysplasia. A systematic search was performed in duplicate for studies investigating the outcome of hip arthroscopy in the setting of hip dysplasia up to July 2015. Study parameters including sample size, definition of dysplasia, outcomes measures, and re-operation rates were obtained. Furthermore, the levels of evidence of studies were collected and quality assessment was performed.Objective
Methods
There is increasing global awareness of adverse
reactions to metal debris and elevated serum metal ion concentrations
following the use of second generation metal-on-metal total hip
arthroplasties. The high incidence of these complications can be
largely attributed to corrosion at the head-neck interface. Severe
corrosion of the taper is identified most commonly in association
with larger diameter femoral heads. However, there is emerging evidence
of varying levels of corrosion observed in retrieved components
with smaller diameter femoral heads. This same mechanism of galvanic
and mechanically-assisted crevice corrosion has been observed in
metal-on-polyethylene and ceramic components, suggesting an inherent
biomechanical problem with current designs of the head-neck interface. We provide a review of the fundamental questions and answers
clinicians and researchers must understand regarding corrosion of
the taper, and its relevance to current orthopaedic practice. Cite this article:
