The aim of this study was to test the null hypothesis that there
is no difference, from the payer perspective, in the cost of treatment
of a distal radial fracture in an elderly patient, aged >
65 years,
between open reduction and internal fixation (ORIF) and closed reduction (CR). Data relating to the treatment of these injuries in the elderly
between January 2007 and December 2015 were extracted using the
Humana and Medicare Advantage Databases. The primary outcome of
interest was the cost associated with treatment. Secondary analysis included
the cost of common complications. Statistical analysis was performed

Materials and Methods
It is well established that there is a strong association between
Perthes’ disease and worsening socioeconomic deprivation. It has
been suggested that the primary determinant driving this association
is exposure to tobacco smoke. This study aimed to examine this hypothesis. A hospital case-control study (n = 149/146) examined the association
between tobacco smoke exposure and Perthes’ disease, adjusting for
area-level socioeconomic deprivation. Tobacco smoke exposure was
assessed by parental questionnaire of smoking habits during pregnancy,
and by quantitative assay of current exposure using the urinary
cotinine-creatinine ratio, which is a widely used and validated
measure of tobacco smoke exposure.Aims
Patients and Methods
The mucopolysaccharidoses (MPS) are a group of
inherited lysosomal storage disorders with clinical manifestations relevant
to the orthopaedic surgeon. Our aim was to review the recent advances
in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising
orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include
the recognition of slowly progressive, late presenting subtypes,
developments in life-prolonging systemic treatment and potentially
new indications for surgical treatment. The outcomes of surgery
in these patients are not yet validated and some procedures have
a high rate of complications which differ from those in patients
who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or
young adults with a previously unrecognised dysplasia of the hip.
Surgeons treating patients with a MPS should report their experience
and studies should include the assessment of function and quality
of life to guide treatment. Cite this article:

We chose unstable extra-capsular hip fractures as our study group
because these types of fractures suffer the largest blood loss.
We hypothesised that tranexamic acid (TXA) would reduce total blood
loss (TBL) in extra-capsular fractures of the hip. A single-centre placebo-controlled double-blinded randomised
clinical trial was performed to test the hypothesis on patients
undergoing surgery for extra-capsular hip fractures. For reasons
outside the control of the investigators, the trial was stopped
before reaching the 120 included patients as planned in the protocol. Aims
Patients and Methods
Hip fracture is a common injury associated with
high mortality, long-term disability and huge socio-economic burden.
Yet there has been relatively little research into best treatment,
and evidence that has been generated has often been criticised for
its poor quality. Here, we discuss the advances made towards overcoming
these criticisms and the future directions for hip fracture research:
how co-ordinating existing national infrastructures and use of now
established clinical research networks will likely go some way towards
overcoming the practical and financial challenges of conducting
large trials. We highlight the importance of large collaborative
pragmatic trials to inform decision/policy makers and the progress
made towards reaching a consensus on a core outcome set to facilitate data
pooling for evidence synthesis and meta-analysis. These advances and future directions are a priority in order
to establish the high-quality evidence base required for this important
group of patients. Cite this article:
The painful subluxed or dislocated hip in adults
with cerebral palsy presents a challenging problem. Prosthetic dislocation
and heterotopic ossification are particular concerns. We present
the first reported series of 19 such patients (20 hips) treated
with hip resurfacing and proximal femoral osteotomy. The pre-operative
Gross Motor Function Classification System (GMFCS) was level V in
13 (68%) patients, level IV in three (16%), level III in one (5%) and
level II in two (11%). The mean age at operation was 37 years (13
to 57). The mean follow-up was 8.0 years (2.7 to 11.6), and 16 of the
18 (89%) contactable patients or their carers felt that the surgery
had been worthwhile. Pain was relieved in 16 of the 18 surviving
hips (89%) at the last follow-up, and the GMFCS level had improved
in seven (37%) patients. There were two (10%) early dislocations;
three hips (15%) required revision of femoral fixation, and two
hips (10%) required revision, for late traumatic fracture of the
femoral neck and extra-articular impingement, respectively. Hence
there were significant surgical complications in a total of seven
hips (35%). No hips required revision for instability, and there
were no cases of heterotopic ossification. We recommend hip resurfacing with proximal femoral osteotomy
for the treatment of the painful subluxed or dislocated hip in patients
with cerebral palsy.
Previous studies of failure mechanisms leading
to revision total knee replacement (TKR) performed between 1986 and
2000 determined that many failed early, with a disproportionate
amount accounted for by infection and implant-associated factors
including wear, loosening and instability. Since then, efforts have
been made to improve implant performance and instruct surgeons in
best practice. Recently our centre participated in a multi-centre evaluation
of 844 revision TKRs from 2010 to 2011. The purpose was to report
a detailed analysis of failure mechanisms over time and to see if
failure modes have changed over the past 10 to 15 years. Aseptic
loosening was the predominant mechanism of failure (31.2%), followed
by instability (18.7%), infection (16.2%), polyethylene wear (10.0%),
arthrofibrosis (6.9%) and malalignment (6.6%). The mean time to
failure was 5.9 years (ten days to 31 years), 35.3% of all revisions
occurred at less than two years, and 60.2% in the first five years.
With improvements in implant and polyethylene manufacture, polyethylene
wear is no longer a leading cause of failure. Early mechanisms of
failure are primarily technical errors. In addition to improving
implant longevity, industry and surgeons must work together to decrease
these technical errors. All reports on failure of TKR contain patients
with unexplained pain who not infrequently have unmet expectations.
Surgeons must work to achieve realistic patient expectations pre-operatively,
and therefore, improve patient satisfaction post-operatively. Cite this article:
Dislocation is one of the most common causes
of patient and surgeon dissatisfaction following hip replacement
and to treat it, the causes must first be understood. Patient factors
include age greater than 70 years, medical comorbidities, female
gender, ligamentous laxity, revision surgery, issues with the abductors,
and patient education. Surgeon factors include the annual quantity
of procedures and experience, the surgical approach, adequate restoration
of femoral offset and leg length, component position, and soft-tissue
or bony impingement. Implant factors include the design of the head
and neck region, and so-called skirts on longer neck lengths. There
should be offset choices available in order to restore soft-tissue
tension. Lipped liners aid in gaining stability, yet if improperly placed
may result in impingement and dislocation. Late dislocation may
result from polyethylene wear, soft-tissue destruction, trochanteric
or abductor disruption and weakness, or infection. Understanding
the causes of hip dislocation facilitates prevention in a majority
of instances. Proper pre-operative planning includes the identification
of patients with a high offset in whom inadequate restoration of
offset will reduce soft-tissue tension and abductor efficiency.
Component position must be accurate to achieve stability without impingement.
Finally, patient education cannot be over-emphasised, as most dislocations occur
early, and are preventable with proper instructions. Cite this article:
Supracondylar humeral fractures are common in
children, but there are no classification systems or radiological parameters
that predict the likelihood of having to perform an open reduction.
In a retrospective case–control study we evaluated the use of the
medial spike angle and fracture tip–skin distance to predict the
mode of reduction (closed or open) and the operating time in fractures
with posterolateral displacement. A total of 21 patients (4.35%) with
a small medial spike angle (<
45°) were identified from a total
of 494 patients, and 42 patients with a medial spike angle of >
45° were randomly selected as controls. The medial spike group had
significantly smaller fracture tip–skin distances (p <
0.001),
longer operating times (p = 0.004) and more complications (p = 0.033)
than the control group. There was no significant difference in the
mode of reduction and a composite outcome measure. After adjustments
for age and gender, only fracture tip–skin distance remained significantly
associated with the operating time (β = -0.724, p = 0.042) and composite
outcome (OR 0.863 (95% confidence interval 0.746 to 0.998); p = 0.048). Paediatric orthopaedic surgeons should have a lower threshold
for open reduction when treating patients with a small medial spike
angle and a small fracture tip–skin distance. Cite this article:
Symptoms of obstetric brachial plexus injury (OBPI) vary widely
over the course of time and from individual to individual and can
include various degrees of denervation, muscle weakness, contractures,
bone deformities and functional limitations. To date, no universally
accepted overall framework is available to assess the outcome of patients
with OBPI. The objective of this paper is to outline the proposed
process for the development of International Classification of Functioning,
Disability and Health (ICF) Core Sets for patients with an OBPI. The first step is to conduct four preparatory studies to identify
ICF categories important for OBPI: a) a systematic literature review
to identify outcome measures, b) a qualitative study using focus
groups, c) an expert survey and d) a cross-sectional, multicentre
study. A first version of ICF Core Sets will be defined at a consensus
conference, which will integrate the evidence from the preparatory
studies. In a second step, field-testing among patients will validate this
first version of Core Sets for OBPI.Background
Methods
In light of the growing number of elderly osteopenic
patients with distal humeral fractures, we discuss the history of
their management and current trends. Under most circumstances operative
fixation and early mobilisation is the treatment of choice, as it
gives the best results. The relative indications for and results

Gender-specific total knee replacement has generated much interest recently. We reviewed 1970 Sigma knees implanted in 920 women and 592 men with a mean age of 69.7 years. At a mean follow-up of 7.3 years (minimum, five years), we found minimal differences in the outcome between genders. At the final follow-up, men had a higher overall Knee Society score and more osteolysis (3.8% vs 1.1%). However, there were no significant differences between men and women in terms of complications or improvements in knee function, pain score or range of movement. The estimated ten-year survivorship was 97% in women and 98% in men (p = 0.96). We concluded that there was little difference in outcome between the genders treated by a modern unisex design of total knee replacement in this large multicentre study.
We studied 60 patients with an acute displaced fracture of the femoral neck and with a mean age of 84 years. They were randomly allocated to treatment by either internal fixation with cannulated screws or hemiarthroplasty using an uncemented Austin Moore prosthesis. All patients had severe cognitive impairment, but all were able to walk independently before the fracture. They were reviewed at four, 12 and 24 months after surgery. Outcome assessments included complications, revision surgery, the status of activities of daily living (ADL), hip function according to the Charnley score and the health-related quality of life (HRQOL) according to the Euroqol (EQ-5D) (proxy report). General complications and the rate of mortality at two years (42%) did not differ between the groups. The rate of hip complications was 30% in the internal fixation group and 23% in the hemiarthroplasty group; this was not significant. There was a trend towards an increased number of re-operated patients in the internal fixation group compared with the hemiarthroplasty group, 33% and 13%, respectively (p = 0.067), but the total number of surgical procedures which were required did not differ between the groups. Of the survivors at two years, 54% were totally dependent in ADL functions and 60% were bedridden or wheelchair-bound regardless of the surgical procedure. There was a trend towards decreased mobility in the hemiarthroplasty group (p = 0.066). All patients had a very low HRQOL even before the fracture. The EQ-5Dindex score was significantly worse in the hemiarthroplasty group compared with the internal fixation group at the final follow-up (p <
0.001). In our opinion, there is little to recommend hemiarthroplasty with an uncemented Austin Moore prosthesis compared with internal fixation, in patients with severe cognitive dysfunction.
