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
Patients and Methods
Loss of motion following spine segment fusion results in increased strain in the adjacent motion segments. However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following cervical fusion and lumbar fusion during simulated whiplash using a whole-human finite element (FE) model to simulate coupled motions of the spine. A previously validated FE model of the human body in the driver-occupant position was used to investigate cervical hyperextension injury. The cervical spine was subjected to simulated whiplash exposure in accordance with Euro NCAP (the European New Car Assessment Programme) testing using the whole human FE model. The coupled motions between the cervical spine and lumbar spine were assessed by evaluating the biomechanical effects of simulated cervical fusion and lumbar fusion.Objectives
Methods
The aim of this study was to report a retrospective, consecutive
series of patients with adolescent idiopathic scoliosis (AIS) who
were treated with posterior minimally invasive surgery (MIS) with
a mean follow-up of two years ( We prospectively collected the data of 70 consecutive patients
with AIS treated with MIS using three incisions and a muscle-splitting
approach by a single surgeon between June 2013 and February 2016
and these were retrospectively reviewed. There were eight male and
62 female patients with a mean age of 15 years (Aims

This prospective study reports the 15-year survival and ten-year
functional outcome of a consecutive series of 1000 minimally invasive
Phase 3 Oxford medial UKAs (818 patients, 393 men, 48%, 425 women,
52%, mean age 66 years; 32 to 88). These were implanted by two surgeons
involved with the design of the prosthesis to treat anteromedial
osteoarthritis and spontaneous osteonecrosis of the knee, which
are recommended indications. Patients were prospectively identified
and followed up independently for a mean of 10.3 years (5.3 to 16.6). At ten years, the mean Oxford Knee Score was 40 (standard deviation
( This is the only large series of minimally invasive UKAs with
15-year survival data. The results support the continued use of
minimally invasive UKA for the recommended indications. Cite this article:
To address the natural history of severe post-tuberculous (TB)
kyphosis, with focus upon the long-term neurological outcome, occurrence
of restrictive lung disease, and the effect on life expectancy. This is a retrospective clinical review of prospectively collected
imaging data based at a single institute. A total of 24 patients
of Southern Chinese origin who presented with spinal TB with a mean
of 113° of kyphosis (65° to 159°) who fulfilled inclusion criteria
were reviewed. Plain radiographs were used to assess the degree
of spinal deformity. Myelography, CT and MRI were used when available
to assess the integrity of the spinal cord and canal. Patient demographics,
age of onset of spinal TB and interventions, types of surgical procedure,
intra- and post-operative complications, and neurological status
were assessed. Aims
Patients and Methods
Although atlantoaxial rotatory fixation (AARF) is a common cause
of torticollis in children, the diagnosis may be delayed. The condition
is characterised by a lack of rotation at the atlantoaxial joint
which becomes fixed in a rotated and subluxed position. The management of
children with a delayed presentation of this condition is controversial.
This is a retrospective study of a group of such children. Children who were admitted to two institutions between 1988 and
2014 with a diagnosis of AARF were included. We identified 12 children
(four boys, eight girls), with a mean age of 7.3 years (1.5 to 13.4),
in whom the duration of symptoms on presentation was at least four weeks
(four to 39). All were treated with halo traction followed by a
period of cervical immobilisation in a halo vest or a Minerva jacket.
We describe a simple modification to the halo traction that allows
the child to move their head whilst maintaining traction. The mean follow-up
was 59.6 weeks (24 to 156).Aims

This study aimed to determine the relationship between pedicle-lengthening
distance and bulge-canal volume ratio in cases of lumbar spinal
stenosis, to provide a theoretical basis for the extent of lengthening
in pedicle-lengthening osteotomies. Three-dimensional reconstructions of CT images were performed
for 69 patients (33 men and 36 women) (mean age 49.96 years; 24
to 81). Simulated pedicle-lengthening osteotomies and disc bulge
and spinal canal volume calculations were performed using Mimics
software. Aims
Methods
A lack of connection between surgeons and patients in evaluating
the outcome of total knee arthroplasty (TKA) has led to the search
for the ideal patient-reported outcome measure (PROM) to evaluate
these procedures. We hypothesised that the desired psychometric properties
of the ideal outcome tool have not been uniformly addressed in studies describing
TKA PROMS. A systematic review was conducted investigating one or more facets
of patient-reported scores for measuring primary TKA outcome. Studies
were analysed by study design, subject demographics, surgical technique,
and follow-up adequacy, with the ‘gold standard’ of psychometric
properties being systematic development, validity, reliability,
and responsiveness.Objectives
Methods
Oxidised zirconium was introduced as a material for femoral components
in total knee arthroplasty (TKA) as an attempt to reduce polyethylene
wear. However, the long-term survival of this component is not known. We performed a retrospective review of a prospectively collected
database to assess the ten year survival and clinical and radiological
outcomes of an oxidised zirconium total knee arthroplasty with the
Genesis II prosthesis. The Western Ontario and McMaster Universities Osteoarthritis
Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS)
and a patient satisfaction scale were used to assess outcome.Aims
Methods
Little biomechanical information is available about kinematically aligned (KA) total knee arthroplasty (TKA). The purpose of this study was to simulate the kinematics and kinetics after KA TKA and mechanically aligned (MA) TKA with four different limb alignments. Bone models were constructed from one volunteer (normal) and three patients with three different knee deformities (slight, moderate and severe varus). A dynamic musculoskeletal modelling system was used to analyse the kinematics and the tibiofemoral contact force. The contact stress on the tibial insert, and the stress to the resection surface and medial tibial cortex were examined by using finite element analysis.Objectives
Materials and Methods
We reviewed 34 consecutive patients (18 female-16 male) with
isthmic spondylolysis and grade I to II lumbosacral spondylolisthesis
who underwent in situ posterolateral arthodesis between the L5 transverse
processes and the sacral ala with the use of iliac crest autograft.
Ten patients had an associated scoliosis which required surgical correction
at a later stage only in two patients with idiopathic curves unrelated
to the spondylolisthesis. No patient underwent spinal decompression or instrumentation
placement. Mean surgical time was 1.5 hours (1 to 1.8) and intra-operative
blood loss 200 ml (150 to 340). There was one wound infection treated
with antibiotics but no other complication. Radiological assessment
included standing posteroanterior and lateral, Ferguson and lateral flexion/extension
views, as well as CT scans. Aims

Although infrequent, a fracture of the cuboid can lead to significant
disruption of the integrity of the midfoot and its function. The
purpose of this study was to classify the pattern of fractures of
the cuboid, relate them to the mechanism of injury and suggest methods
of managing them. We performed a retrospective review of patients with radiologically
reported cuboid fractures. Fractures were grouped according to commonly
occurring patterns of injury. A total of 192 fractures in 188 patients
were included. They were classified into five patterns of injury.Aims
