The primary aim of this retrospective study was to identify the
incidence of heterotopic ossification (HO) following elective and
trauma elbow arthroplasty. The secondary aim was to determine clinical
outcomes with respect to the formation of heterotopic ossification. A total of 55 total elbow arthroplasties (TEAs) (52 patients)
performed between June 2007 and December 2015 were eligible for
inclusion in the study (29 TEAs for primary elective arthroplasty
and 26 TEAs for trauma). At review, 15 patients (17 total elbow
arthroplasties) had died from unrelated causes. There were 14 men
and 38 women with a mean age of 70 years (42 to 90). The median
clinical follow-up was 3.6 years (1.2 to 6) and the median radiological follow-up
was 3.1 years (0.5 to 7.5).Aim
Patients and Methods
To examine incidence of complications associated with outpatient
total hip arthroplasty (THA), and to see if medical comorbidities
are associated with complications or extended length of stay. From June 2013 to December 2016, 1279 patients underwent 1472
outpatient THAs at our free-standing ambulatory surgery centre.
Records were reviewed to determine frequency of pre-operative medical
comorbidities and post-operative need for overnight stay and complications
which arose.Aims
Patients and Methods
The best method of treating unstable pelvic fractures that involve
the obturator ring is still a matter for debate. This study compared
three methods of treatment: nonoperative, isolated posterior fixation
and combined anteroposterior stabilization. The study used data from the German Pelvic Trauma Registry and
compared patients undergoing conservative management (n = 2394),
surgical treatment (n = 1345) and transpubic surgery, including
posterior stabilization (n = 730) with isolated posterior osteosynthesis
(n = 405) in non-complex Type B and C fractures that only involved the
obturator ring anteriorly. Calculated odds ratios were adjusted
for potential confounders. Outcome criteria were intraoperative
and general short-term complications, the incidence of nerve injuries,
and mortality.Aims

‘Big data’ is a term for data sets that are so
large or complex that traditional data processing applications are
inadequate. Billions of dollars have been spent on attempts to build predictive
tools from large sets of poorly controlled healthcare metadata.
Companies often sell reports at a physician or facility level based
on various flawed data sources, and comparative websites of ‘publicly
reported data’ purport to educate the public. Physicians should
be aware of concerns and pitfalls seen in such data definitions,
data clarity, data relevance, data sources and data cleaning when
evaluating analytic reports from metadata in health care. Cite this article:
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:
The objective of this study was to assess all evidence comparing the Thompson monoblock hemiarthroplasty with modular unipolar implants for patients requiring hemiarthroplasty of the hip with respect to mortality and complications. A literature search was performed to identify all relevant literature. The population consisted of patients undergoing hemiarthroplasty of the hip for fracture. The intervention was hemiarthroplasty of the hip with a comparison between Thompson and modular unipolar prostheses. Pubmed, Embase, CINAHL, Web of Science, PROSPERO and the Cochrane Central Register of Controlled Trials. The study designs included were randomised controlled trials (RCTs), well designed case control studies and retrospective or prospective cohort studies. Studies available in any language, published at any time until September 2015 were considered. Studies were included if they contained mortality or complications.Objectives
Methods
Patellofemoral arthroplasty (PFA) has experienced significant
improvements in implant survivorship with second generation designs.
This has renewed interest in PFA as an alternative to total knee
arthroplasty (TKA) for younger active patients with isolated patellofemoral
osteoarthritis (PF OA). We analysed the cost-effectiveness of PFA We used a Markov transition state model to compare cost-effectiveness
between PFA and TKA. Simulated patients were aged 60 (base case)
and 50 years. Lifetime costs (2015 United States dollars), quality-adjusted
life year (QALY) gains and incremental cost-effectiveness ratio
(ICER) were calculated from a healthcare payer perspective. Annual rates
of revision were derived from the National Joint Registry for England,
Wales, Northern Ireland and the Isle of Man. Deterministic and probabilistic
sensitivity analysis was performed for all parameters against a
$50 000/QALY willingness to pay. Aims
Patients and Methods
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
