Single-event multilevel surgery (SEMLS) has been used as an effective
intervention in children with bilateral spastic cerebral palsy (BSCP)
for 30 years. To date there is no evidence for SEMLS in adults with
BSCP and the intervention remains focus of debate. This study analysed the short-term outcome (mean 1.7 years, standard
deviation 0.9) of 97 ambulatory adults with BSCP who performed three-dimensional
gait analysis before and after SEMLS at one institution. Aims
Methods
Myxofibrosarcomas (MFSs) are malignant soft-tissue sarcomas characteristically
presenting as painless slowly growing masses in the extremities.
Locally infiltrative growth means that the risk of local recurrence
is high. We reviewed our experience to make recommendations about
resection strategies and the role of the multidisciplinary team
in the management of these tumours. Patients with a primary or recurrent MFS who were treated surgically
in our unit between 1997 and 2012 were included in the study. Clinical
records and imaging were reviewed. A total of 50 patients with a
median age of 68.4 years (interquartile range 61.6 to 81.8) were
included. There were 35 men; 49 underwent surgery in our unit.Aims
Patients and Methods
The aim of this study is to introduce and investigate the efficacy
and feasibility of a new vertebral osteotomy technique, vertebral
column decancellation (VCD), for rigid thoracolumbar kyphotic deformity
(TLKD) secondary to ankylosing spondylitis (AS). We took 39 patients from between January 2009 and January 2013
(26 male, 13 female, mean age 37.4 years, 28 to 54) with AS and
a TLKD who underwent VCD (VCD group) and compared their outcome
with 45 patients (31 male, 14 female, mean age 34.8 years, 23 to
47) with AS and TLKD, who underwent pedicle subtraction osteotomy
(PSO group), according to the same selection criteria. The technique
of VCD was performed at single vertebral level in the thoracolumbar
region of AS patients according to classification of AS kyphotic
deformity. Pre- and post-operative chin-brow vertical angle (CBVA),
sagittal vertical axis (SVA) and sagittal Cobb angle in the thoracolumbar
region were reviewed in the VCD and PSO groups. Intra- , post-operative
and general complications were analysed in both group.Aims
Patients and Methods
The purpose of this study was to evaluate the
effect of various non-operative modalities of treatment (transcutaneous
electrical nerve stimulation (TENS); neuromuscular electrical stimulation
(NMES); insoles and bracing) on the pain of osteoarthritis (OA)
of the knee. We conducted a systematic review according to the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses guidelines to identify
the therapeutic options which are commonly adopted for the management
of osteoarthritis (OA) of the knee. The outcome measurement tools used in the different studies were
the visual analogue scale and The Western Ontario and McMaster Universities
Arthritis Index pain index: all pain scores were converted to a
100-point scale. A total of 30 studies met our inclusion criteria: 13 on insoles,
seven on TENS, six on NMES, and four on bracing. The standardised
mean difference (SMD) in pain after treatment with TENS was 1.796,
which represented a significant reduction in pain. The significant
overall effect estimate for NMES on pain was similar to that of
TENS, with a SMD of 1.924. The overall effect estimate of insoles
on pain was a SMD of 0.992. The overall effect of bracing showed
a significant reduction in pain of 1.34. Overall, all four non-operative modalities of treatment were
found to have a significant effect on the reduction of pain in OA
of the knee. This study shows that non-operative physical modalities of treatment
are of benefit when treating OA of the knee. However, much of the
literature reviewed evaluates studies with follow-up of less than
six months: future work should aim to evaluate patients with longer
follow-up. Cite this article:
Fractures around total knee arthroplasties pose
a significant surgical challenge. Most can be managed with osteosynthesis
and salvage of the replacement. The techniques of fixation of these
fractures and revision surgery have evolved and so has the assessment
of outcome. This specialty update summarises the current evidence
for the classification, methods of fixation, revision surgery and
outcomes of the management of periprosthetic fractures associated
with total knee arthroplasty. Cite this article:
The purpose of this study was to analyse the biomechanics of
walking, through the ground reaction forces (GRF) measured, after
first metatarsal osteotomy or metatarsophalangeal joint (MTP) arthrodesis. A total of 19 patients underwent a Scarf osteotomy (50.3 years,

Patients 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:
The aim of this study was to analyse the effect of altered viewing
perspectives on the measurement of the glenopolar angle (GPA) and
the differences between these measurements made on 3D CT reconstructions
and anteroposterior (AP) scapular view radiographs. The influence of the viewing perspective on the GPA was assessed,
as were the differences in the measurements of the GPA between 3D
CT reconstructions and AP scapular view radiographs in 68 cadaveric
scapulae.Aims
Materials and Methods
The aim of this study was to compare the effect of a percutaneous
radiofrequency heat lesion at the medial branch of the primary dorsal
ramus with a sham procedure, for the treatment of lumbar facet joint
pain. A randomised sham-controlled double blind multicentre trial was
carried out at the multidisciplinary pain centres of two hospitals.
A total of 60 patients aged >
18 years with a history and physical
examination suggestive of facet joint pain and a decrease of ≥ 2
on a numerical rating scale (NRS 0 to 10) after a diagnostic facet
joint test block were included. In the treatment group, a percutaneous
radiofrequency heat lesion (80oC during 60 seconds per
level) was applied to the medial branch of the primary dorsal ramus.
In the sham group, the same procedure was undertaken without for
the radiofrequency lesion. Both groups also received a graded activity
physiotherapy programme. The primary outcome measure was decrease
in pain. A secondary outcome measure was the Global Perceived Effect scale
(GPE).Aims
Patients and Methods
This study investigates and defines the topographic
anatomy of the medial femoral circumflex artery (MFCA) terminal
branches supplying the femoral head (FH). Gross dissection of 14
fresh–frozen cadaveric hips was undertaken to determine the extra
and intracapsular course of the MFCA’s terminal branches. A constant
branch arising from the transverse MFCA (inferior retinacular artery;
IRA) penetrates the capsule at the level of the anteroinferior neck,
then courses obliquely within the fibrous prolongation of the capsule
wall (inferior retinacula of Weitbrecht), elevated from the neck,
to the posteroinferior femoral head–neck junction. This vessel has
a mean of five (three to nine) terminal branches, of which the majority
penetrate posteriorly. Branches from the ascending MFCA entered
the femoral capsular attachment posteriorly, running deep to the
synovium, through the neck, and terminating in two branches. The
deep MFCA penetrates the posterosuperior femoral capsular. Once
intracapsular, it divides into a mean of six (four to nine) terminal
branches running deep to the synovium, within the superior retinacula
of Weitbrecht of which 80% are posterior. Our study defines the
exact anatomical location of the vessels, arising from the MFCA
and supplying the FH. The IRA is in an elevated position from the
femoral neck and may be protected from injury during fracture of
the femoral neck. We present vascular ‘danger zones’ that may help
avoid iatrogenic vascular injury during surgical interventions about
the hip. Cite this article:
The aim of this consensus was to develop a definition of post-operative
fibrosis of the knee. An international panel of experts took part in a formal consensus
process composed of a discussion phase and three Delphi rounds.Aims
Patients and Methods
A fracture of the hip is the most common serious orthopaedic
injury, and surgical site infection (SSI) is one of the most significant
complications, resulting in increased mortality, prolonged hospital
stay and often the need for further surgery. Our aim was to determine
whether high dose dual antibiotic impregnated bone cement decreases the
rate of infection. A quasi-randomised study of 848 patients with an intracapsular
fracture of the hip was conducted in one large teaching hospital
on two sites. All were treated with a hemiarthroplasty. A total
of 448 patients received low dose single-antibiotic impregnated
cement (control group) and 400 patients received high dose dual-antibiotic impregnated
cement (intervention group). The primary outcome measure was deep
SSI at one year after surgery.Aims

This is the first prospective study to report the pre- and post-operative
patient reported outcomes and satisfaction scores following excision
of interdigital Morton’s neuroma. Between May 2006 and April 2013, we prospectively studied 99
consecutive patients (111 feet) who were to undergo excision of
a Morton’s neuroma. There were 78 women and 21 men with a mean age
at the time of surgery of 56 years (22 to 78). Patients completed
the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12
(SF-12) and a supplementary patient satisfaction survey three months
pre-operatively and six months post-operatively.Aims

Rib fracture fixation by orthopaedic and cardiothoracic surgeons has become increasingly popular for the treatment of chest injuries in trauma. The literature, though mainly limited to Level II and III evidence, shows favourable results for operative fixation. In this paper we review the literature and discuss the indications for rib fracture fixation, surgical approaches, choice of implants and the future direction for management. With the advent of NICE guidance and new British Orthopaedic Association Standards for Trauma (BOAST) guidelines in production, the management of rib fractures is going to become more and more commonplace.
In 11 paediatric patients (seven girls and four
boys, from 12 to 15 years old) with unilateral obligatory patellar dislocation
and ligamentous laxity vastus medialis advancement, lateral release,
partial patellar ligament transposition and Galeazzi semitendinosus
tenodesis was undertaken to stabilise the patella. The diagnostic criterion
for ligamentous laxity was based on the Beighton scale. Outcomes
were evaluated radiologically and functionally by measurement of
the range of knee movement and isokinetic testing. The evaluation
also included the Lysholm knee scale. Follow-up studies took place
at a mean of 8.1 years (5 to 15) post-operatively. Normal patellar tracking without any recurrence of dislocation
was obtained in ten out of 11 patients. Pain related to vigorous
activity was reported by nine patients. Compared with the opposite
normal side, the isokinetic tests revealed a statistically significant
decrease in the maximal torque values for the affected quadriceps
muscle (p = 0.003 and p = 0.004), but no difference between the
knee flexors (for angular velocities of 60°/s and 180°/s) (p = 0.858
and p = 0.79). The applied surgical technique generally prevents the recurrence
of the disorder in children with habitual patellar dislocation and
ligamentous laxity. Quadriceps muscle weakness can be expected to
occur post-operatively, Cite this article:
Percutaneous placement of pedicle screws is a
well-established technique, however, no studies have compared percutaneous
and open placement of screws in the thoracic spine. The aim of this
cadaveric study was to compare the accuracy and safety of these
techniques at the thoracic spinal level. A total of 288 screws were
inserted in 16 (eight cadavers, 144 screws in percutaneous and eight
cadavers, 144 screws in open). Pedicle perforations and fractures
were documented subsequent to wide laminectomy followed by skeletalisation
of the vertebrae. The perforations were classified as grade 0: no
perforation, grade 1: <
2 mm perforation, grade 2: 2 mm to 4
mm perforation and grade 3: >
4 mm perforation. In the percutaneous
group, the perforation rate was 11.1% with 15 (10.4%) grade 1 and
one (0.7%) grade 2 perforations. In the open group, the perforation
rate was 8.3% (12 screws) and all were grade 1. This difference
was not significant (p = 0.45). There were 19 (13.2%) pedicle fractures
in the percutaneous group and 21 (14.6%) in the open group (p =
0.73). In summary, the safety of percutaneous fluoroscopy-guided
pedicle screw placement in the thoracic spine between T4 and T12
is similar to that of the conventional open technique. Cite this article:
Only limited data are available regarding the
infiltration of local anaesthetic for total hip arthroplasty (THA),
and no studies were performed for THA using the anterior approach. In this prospective, randomised placebo-controlled study we investigated
the effect of both standard and reverse infiltration of local anaesthetic
in combination with the anterior approach for THA. The primary endpoint
was the mean numeric rating score for pain four hours post-operatively.
In addition, we recorded the length of hospital stay, the operating
time, the destination of the patient at discharge, the use of pain
medication, the occurrence of side effects and pain scores at various
times post-operatively. Between November 2012 and January 2014, 75 patients were included
in the study. They were randomised into three groups: standard infiltration
of local anaesthetic, reversed infiltration of local anaesthetic,
and placebo. There was no difference in mean numeric rating score
for pain four hours post-operatively (p = 0.87). There were significantly
more side effects at one and eight hours post-operatively in the
placebo group (p = 0.02; p = 0.03), but this did not influence the
mobilisation of the patients. There were no differences in all other
outcomes between the groups. We found no clinically relevant effect when the infiltration
of local anaesthetic with ropivacaine and epinephrine was used in
a multimodal pain protocol for THA using the anterior approach. Cite this article:
Single event multilevel surgery (SEMLS) has been shown to improve
gait in children with cerebral palsy (CP). However, there is limited
evidence regarding long-term outcomes and factors influencing them. In total 39 children (17 females and 22 males; mean age at SEMLS
ten years four months, standard deviation 37 months) with bilateral
CP (20 Gross Motor Function Classification System (GMFCS) level
II and 19 GMFCS level III) treated with SEMLS were included. Children
were evaluated using gait analysis and the Gait Deviation Index
(GDI) before SEMLS and one, two to three, five and at least ten
years after SEMLS. A linear mixed model was used to estimate the
effect of age at the surgery, GMFCS and follow-up period on GDI. Aims
