Our aim was to examine the clinical and radiographic outcomes
in 257 consecutive Oxford unicompartmental knee arthroplasties (OUKAs)
(238 patients), five years post-operatively. A retrospective evaluation was undertaken of patients treated
between April 2008 and October 2010 in a regional centre by two
non-designing surgeons with no previous experience of UKAs. The
Oxford Knee Scores (OKSs) were recorded and fluoroscopically aligned
radiographs were assessed post-operatively at one and five years.Aims
Patients and Methods
Few studies dealing with chondrosarcoma of the pelvis are currently
available. Different data about the overall survival and prognostic
factors have been published but without a detailed analysis of surgery-related complications.
We aimed to analyse the outcome of a series of pelvic chondrosarcomas
treated at a single institution, with particular attention to the
prognostic factors. Based on a competing risk model, our objective
was to identify risk factors for the development of complications. In a retrospective single-centre study, 58 chondrosarcomas (26
patients alive, 32 patients dead) of the pelvis were reviewed. The
mean follow-up was 13 years (one week to 23.1 years).Aims
Patients and Methods
Our aim was to determine whether, based on the current literature,
bariatric surgery prior to total hip (THA) or total knee arthroplasty
(TKA) reduces the complication rates and improves the outcome following
arthroplasty in obese patients. A systematic literature search was undertaken of published and
unpublished databases on the 5 November 2015. All papers reporting
studies comparing obese patients who had undergone bariatric surgery
prior to arthroplasty, or not, were included. Each study was assessed
using the Downs and Black appraisal tool. A meta-analysis of risk ratios
(RR) and 95% confidence intervals (CI) was performed to determine
the incidence of complications including wound infection, deep vein
thrombosis (DVT), pulmonary embolism (PE), revision surgery and
mortality.Aims
Methods
To present our experience of using a combination of intra-articular
osteotomy and external fixation to treat different deformities of
the knee. A total of six patients with a mean age of 26.5 years (15 to
50) with an abnormal hemi-joint line convergence angle (HJLCA) and
mechanical axis deviation (MAD) were included. Elevation of a tibial
hemiplateau or femoral condylar advancement was performed and limb
lengthening with correction of residual deformity using a circular
or monolateral Ilizarov frame.Aims
Patients and Methods
There are various pin-in-plaster methods for treating fractures
of the distal radius. The purpose of this study is to introduce
a modified technique of ‘pin in plaster’. Fifty-four patients with fractures of the distal radius were
followed for one year post-operatively. Patients were excluded if
they had type B fractures according to AO classification, multiple
injuries or pathological fractures, and were treated more than seven
days after injury. Range of movement and functional results were
evaluated at three and six months and one and two years post-operatively.
Radiographic parameters including radial inclination, tilt, and
height, were measured pre- and post-operatively.Objectives
Methods
We carried out a further study of the long-term results of the
cemented Exeter femoral component in patients under the age of 40
with a mean follow-up of 13.6 years (10 to 20). We reviewed our original cohort of 104 cemented Exeter stems
in 78 consecutive patients with a mean age of 31 years (16 to 39).
Only one patient was lost to radiological follow-up.Aims
Patients and Methods
This study compared the quality of reduction
and complication rate when using a standard ilioinguinal approach and
the new pararectus approach when treating acetabular fractures surgically.
All acetabular fractures that underwent fixation using either approach
between February 2005 and September 2014 were retrospectively reviewed
and the demographics of the patients, the surgical details and complications
were recorded. A total of 100 patients (69 men, 31 women; mean age 57 years,
18 to 93) who were consecutively treated were included for analysis.
The quality of reduction was assessed using standardised measurement
of the gaps and steps in the articular surface on pre- and post-operative
CT-scans. There were no significant differences in the demographics of
the patients, the surgical details or the complications between
the two approaches. A significantly better reduction of the gap,
however, was achieved with the pararectus approach (axial: p = 0.025,
coronal: p = 0.013, sagittal: p = 0.001). These data suggest that the pararectus approach is at least equal
to, or in the case of reduction of the articular gap, superior to
the ilioinguinal approach. This approach allows direct buttressing of the dome of the acetabulum
and the quadrilateral plate, which is particularly favourable in
geriatric fracture patterns. Cite this article:
Lifestyle risk factors are thought to increase the risk of infection
after acute orthopaedic surgery but the evidence is scarce. We aimed
to investigate whether smoking, obesity and alcohol overuse are
risk factors for the development of infections after surgery for
a fracture of the ankle. We retrospectively reviewed all patients who underwent internal
fixation of a fracture of the ankle between 2008 and 2013. The primary
outcome was the rate of deep infection and the secondary outcome
was any surgical site infection (SSI). Associations with the risk
factors and possible confounding variables were analysed univariably
and multivariably with backwards elimination.Aims
Patients and Methods
Children treated for osteosarcoma around the knee often have
a substantial leg-length discrepancy at skeletal maturity. The aim
of this study was to investigate the results of staged skeletal
reconstruction after a leg lengthening procedure using an external
fixator in these patients. We reviewed 11 patients who underwent staged reconstruction with
either an arthroplasty (n = 6) or an arthrodesis (n = 5). A control
group of 11 patients who had undergone wide excision and concurrent
reconstruction with an arthroplasty were matched for gender, location,
and size of tumour. We investigated the change in leg-length discrepancy,
function as assessed by the Musculoskeletal Tumor Society Scale
(MSTS) score and complications.Aims
Patients and Methods
To compare the outcomes for trochanteric fractures treated with
a sliding hip screw (SHS) or a cephalomedullary nail. A total of 400 patients with a trochanteric hip fracture were
randomised to receive a SHS or a cephalomedullary nail (Targon PFT).
All surviving patients were followed up to one year from injury.
Functional outcome was assessed by a research nurse blinded to the
implant used.Aims
Patients and Methods
In the time since Letournel popularised the surgical
treatment of acetabular fractures, more than 25 years ago, there
have been many changes within the field, related to patients, surgical
technique, implants and post-operative care. However, the long-term
outcomes appear largely unchanged. Does this represent stasis or
have the advances been mitigated by other negative factors? In this
article we have attempted to document the recent changes within
the surgery of patients with a fracture involving the acetabulum,
outline contemporary management, and identify the major problem
areas where further research is most needed. Cite this article:
Since redesign of the Oxford phase III mobile-bearing unicompartmental
knee arthroplasty (UKA) femoral component to a twin-peg design,
there has not been a direct comparison to total knee arthroplasty
(TKA). Thus, we explored differences between the two cohorts. A total of 168 patients (201 knees) underwent medial UKA with
the Oxford Partial Knee Twin-Peg. These patients were compared with
a randomly selected group of 177 patients (189 knees) with primary
Vanguard TKA. Patient demographics, Knee Society (KS) scores and
range of movement (ROM) were compared between the two cohorts. Additionally,
revision, re-operation and manipulation under anaesthesia rates
were analysed.Aims
Patients and Methods
We present the results of correcting a double or triple curve
adolescent idiopathic scoliosis using a convex segmental pedicle
screw technique. We reviewed 191 patients with a mean age at surgery of 15 years
(11 to 23.3). Pedicle screws were placed at the convexity of each
curve. Concave screws were inserted at one or two cephalad levels
and two caudal levels. The mean operating time was 183 minutes (132
to 276) and the mean blood loss 0.22% of the total blood volume
(0.08% to 0.4%). Multimodal monitoring remained stable throughout
the operation. The mean hospital stay was 6.8 days (5 to 15).Aims
Patients and Methods
The diagnosis of surgical site infection following endoprosthetic reconstruction for bone tumours is frequently a subjective diagnosis. Large clinical trials use blinded Central Adjudication Committees (CACs) to minimise the variability and bias associated with assessing a clinical outcome. The aim of this study was to determine the level of inter-rater and intra-rater agreement in the diagnosis of surgical site infection in the context of a clinical trial. The Prophylactic Antibiotic Regimens in Tumour Surgery (PARITY) trial CAC adjudicated 29 non-PARITY cases of lower extremity endoprosthetic reconstruction. The CAC members classified each case according to the Centers for Disease Control (CDC) criteria for surgical site infection (superficial, deep, or organ space). Combinatorial analysis was used to calculate the smallest CAC panel size required to maximise agreement. A final meeting was held to establish a consensus.Objectives
Materials and Methods
This study compares the cost-effectiveness of
treating dorsally displaced distal radial fractures with a volar
locking plate and percutaneous fixation. It was performed from the
perspective of the National Health Service (NHS) using data from
a single-centre randomised controlled trial. In total 130 patients
(18 to 73 years of age) with a dorsally displaced distal radial
fracture were randomised to treatment with either a volar locking
plate (n = 66) or percutaneous fixation (n = 64). The methodology
was according to National Institute for Health and Care Excellence guidance
for technology appraisals. . There were no significant differences in quality of life scores
between groups at any time point in the study. Both groups returned
to baseline one year post-operatively. NHS costs for the plate group were significantly higher (p <
0.001, 95% confidence interval 497 to 930). For an additional £713,
fixation with a volar locking plate offered 0.0178 additional quality-adjusted
life years in the year after surgery. The incremental cost-effectiveness
ratio (ICER) for plate fixation relative to percutaneous fixation
at list price was £40 068. When adjusting the prices of the implants
for a 20% hospital discount, the ICER was £31 898. Patients who
underwent plate fixation did not return to work earlier. We found no evidence to support the cost-effectiveness, from
the perspective of the NHS, of fixation using a volar locking plate
over percutaneous fixation for the operative treatment of a dorsally
displaced radial fracture. Cite this article:
Most of the literature on surgical site infections
following the surgical treatment of fractures of the ankle is based
on small series of patients, focusing on diabetics or the elderly.
None have described post-operative functional scores in those patients
who develop an infection. We performed an age- and gender-matched
case–control study to identify patient- and surgery-related risk
factors for surgical site infection following open reduction and
internal fixation of a fracture of the ankle. Logistic regression
analysis was used to identify significant risk factors for infection
and to calculate odds ratios (OR). Function was assessed using the
Olerud and Molander Ankle Score. The incidence of infection was
4% (29/717) and 1.1% (8/717) were deep infections. The median ankle
score was significantly lower in the infection group compared with
the control group (60 A low incidence of infection following open reduction and internal
fixation of fractures of the ankle was observed. Both superficial
and deep infections result in lower functional scores. 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
