The aim of this paper is to review the evidence relating to the
anatomy of the proximal femur, the geometry of the fracture and
the characteristics of implants and methods of fixation of intertrochanteric
fractures of the hip. Relevant papers were identified from appropriate clinical databases
and a narrative review was undertaken.Aims
Materials and Methods
Femoral impaction bone grafting was first developed in 1987 using
morselised cancellous bone graft impacted into the femoral canal
in combination with a cemented, tapered, polished stem. We describe
the evolution of this technique and instrumentation since that time. Between 1987 and 2005, 705 revision total hip arthroplasties
(56 bilateral) were performed with femoral impaction grafting using
a cemented femoral stem. All surviving patients were prospectively
followed for a mean of 14.7 years (9.8 to 28.3) with no loss to
follow-up. By the time of the final review, 404 patients had died.Aims
Patients and Methods
A possible solution for the management of proximal femoral bone
loss is a modular femoral endoprosthesis (EPR). Although the outcome
of EPRs in tumour surgery has been well described, the outcome of
their use in revision hip surgery has received less attention. The
aim of this study was to describe the outcome of using EPR for non-neoplastic
indications. A retrospective review of 79 patients who underwent 80 EPRs for
non-neoplastic indications was performed, including the rates of
complication and survival and the mean Oxford Hip Scores (OHS),
at a mean of five years post-operatively. The mean age at the time
of surgery was 69 years (28 to 93) and the mean number of previous operations
on the hip was 2.4 (0 to 17). The most common indications for EPR
implantation were periprosthetic joint infection (PJI) (n = 40),
periprosthetic fracture (n = 12) and failed osteosynthesis of a
proximal femoral fracture or complex trauma (n = 11).Objectives
Methods
Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients. Patients with single-level acute osteoporotic vertebral compression fracture at thoracolumbar junction (T10 to L2) were followed. If the patients were not satisfied with acute pain reduction after a three-week conservative treatment, vertebroplasty was recommended. Pain assessment was carried out at the time of diagnosis, as well as three, four, six, and 12 weeks after the diagnosis. The effect of vertebroplasty, compared with conservative treatment, on back pain (visual analogue score, VAS) was analysed with the use of analysis-of-covariance models that adjusted for pre-operative VAS scores.Objectives
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
Patients and Methods
A successful outcome following treatment of nonunion requires the correct identification of all of the underlying cause(s) and addressing them appropriately. The aim of this study was to assess the distribution and frequency of causative factors in a consecutive cohort of nonunion patients in order to optimise the management strategy for individual patients presenting with nonunion. Causes of the nonunion were divided into four categories: mechanical; infection; dead bone with a gap; and host. Prospective and retrospective data of 100 consecutive patients who had undergone surgery for long bone fracture nonunion were analysed.Objectives
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
In this study, we aimed to determine whether designation as a
major trauma centre (MTC) affects the quality of care for patients
with a fracture of the hip. All patients in the United Kingdom National Hip Fracture Database,
between April 2010 and December 2013, were included. The indicators
of quality that were recorded included the time to arrival on an
orthopaedic ward, to review by a geriatrician, and to operation.
The clinical outcomes were the development of a pressure sore, discharge
home, length of stay, in-hospital mortality, and re-operation within
30 days. Aims
Patients and Methods
The optimal management of intracapsular fractures of the femoral
neck in independently mobile patients remains open to debate. Successful
fixation obviates the limitations of arthroplasty for this group
of patients. However, with fixation failure rates as high as 30%,
the outcome of revision surgery to salvage total hip arthroplasty
(THA) must be considered. We carried out a systematic review to
compare the outcomes of salvage THA and primary THA for intracapsular
fractures of the femoral neck. We performed a Preferred Reporting Items for Systematic Reviews
and Meta-Analysis (PRISMA) compliant systematic review, using the
PubMed, EMBASE and Cochrane libraries databases. A meta-analysis
was performed where possible, and a narrative synthesis when a meta-analysis
was not possible.Aims
Patients and Methods
Obesity is a worldwide epidemic that has both
economic and health implications of enormous consequence. The obese
patients tend to have earlier symptoms related to osteoarthritis,
more peri-operative medical problems, higher rates of infection
and more technical difficulties intra-operatively following hip
and knee arthroplasty. Nevertheless, these patients have good long-term
clinical outcomes and implant survival rates and are often some of
the most satisfied patients after joint arthroplasty. Therefore,
obese patients should not be denied surgery based on their weight
alone. Cite this article:
Currently, there is little information about the need for peri-operative
blood transfusion in patients undergoing shoulder arthroplasty. The purpose of this study was to identify the rate of transfusion
and its predisposing factors, and to establish a blood conservation
strategy. We identified all patients who had undergone shoulder arthroplasty
at our hospital between 1 January 2011 and 31 December 2013. The
rate of transfusion was determined from the patient’s records. While
there were exceptions, patients typically underwent transfusion
if they had a level of haemoglobin of <
7.5 g/dl if asymptomatic,
<
9.0 g/dl if they had a significant cardiac history or symptoms
of dizziness or light headedness. Multivariable regression analysis was undertaken to identify
predictors of transfusion. High- and low-risk cohorts for transfusion
were identified from a receiver operating characteristic (ROC) curve.Aims
Methods
The aim of this study was to present data on 11 459 patients
who underwent total hip (THA), total knee (TKA) or unicompartmental
knee arthroplasty (UKA) between November 2002 and April 2014 with
aspirin as the primary agent for pharmacological thromboprophylaxis. We analysed the incidence of deep vein thrombosis (DVT) and pulmonary
embolism (PE) then compared the 90-day all-cause mortality with
the corresponding data in the National Joint Registry for England
and Wales (NJR). Aims
Patients and Methods
The aims of this study were to evaluate the clinical and radiological
outcomes of instrumented posterolateral fusion (PLF) performed in
patients with rheumatoid arthritis (RA). A total of 40 patients with RA and 134 patients without RA underwent
instrumented PLF for spinal stenosis between January 2003 and December
2011. The two groups were matched for age, gender, bone mineral
density, the history of smoking and diabetes, and number of fusion
segments. The clinical outcomes measures included the visual analogue scale
(VAS) and the Korean Oswestry Disability Index (KODI), scored before
surgery, one year and two years after surgery. Radiological outcomes
were evaluated for problems of fixation, nonunion, and adjacent
segment disease (ASD). The mean follow-up was 36.4 months in the RA
group and 39.1 months in the non-RA group.Aims

Data on early morbidity and complications after
revision total hip replacement (THR) are limited. The aim of this nationwide
study was to describe and quantify early morbidity after aseptic
revision THR and relate the morbidity to the extent of the revision
surgical procedure. We analysed all aseptic revision THRs from 1st
October 2009 to 30th September 2011 using the Danish National Patient
Registry, with additional information from the Danish Hip Arthroplasty
Registry. There were 1553 procedures (1490 patients) performed in
40 centres and we divided them into total revisions, acetabular
component revisions, femoral stem revisions and partial revisions.
The mean age of the patients was 70.4 years (25 to 98) and the median
hospital stay was five days (interquartile range 3 to 7). Within 90
days of surgery, the readmission rate was 18.3%, mortality rate
1.4%, re-operation rate 6.1%, dislocation rate 7.0% and infection
rate 3.0%. There were no differences in these outcomes between high-
and low-volume centres. Of all readmissions, 255 (63.9%) were due
to ‘surgical’ complications Cite this article:

We present detailed information about early morbidity
after aseptic revision knee replacement from a nationwide study.
All aseptic revision knee replacements undertaken between 1st October
2009 and 30th September 2011 were analysed using the Danish National
Patient Registry with additional information from the Danish Knee
Arthroplasty Registry. The 1218 revisions involving 1165 patients
were subdivided into total revisions, large partial revisions, partial
revisions and revisions of unicondylar replacements (UKR revisions).
The mean age was 65.0 years (27 to 94) and the median length of
hospital stay was four days (interquartile range: 3 to 5), with
a 90 days re-admission rate of 9.9%,
re-operation rate of 3.5% and mortality rate of 0.2%. The age ranges
of 51 to 55 years (p = 0.018), 76 to 80 years (p <
0.001) and ≥ 81
years (p <
0.001) were related to an increased risk of re-admission.
The age ranges of 76 to 80 years (p = 0.018) and the large partial
revision subgroup (p = 0.073) were related to an increased risk
of re-operation. The ages from 76 to 80 years (p <
0.001), age ≥ 81
years (p <
0.001) and surgical time >
120 min (p <
0.001)
were related to increased length of hospital stay, whereas the use
of a tourniquet (p = 0.008) and surgery in a low volume centre (p
= 0.013) were related to shorter length of stay. In conclusion, we found a similar incidence of early post-operative
morbidity after aseptic knee revisions as has been reported after
primary procedures. This suggests that a length of hospital stay ≤ four
days and discharge home at that time is safe following aseptic knee
revision surgery in Denmark. Cite this article:
There is a large amount of evidence available
about the relative merits of unicompartmental and total knee arthroplasty
(UKA and TKA). Based on the same evidence, different people draw
different conclusions and as a result, there is great variability
in the usage of UKA. The revision rate of UKA is much higher than TKA and so some
surgeons conclude that UKA should not be performed. Other surgeons
believe that the main reason for the high revision rate is that
UKA is easy to revise and, therefore, the threshold for revision
is low. They also believe that UKA has many advantages over TKA
such as a faster recovery, lower morbidity and mortality and better
function. They therefore conclude that UKA should be undertaken
whenever appropriate. The solution to this argument is to minimise the revision rate
of UKA, thereby addressing the main disadvantage of UKA. The evidence
suggests that this will be achieved if surgeons use UKA for at least
20% of their knee arthroplasties and use implants that are appropriate
for these broad indications. Cite this article:
