Options for the treatment of subcapital femoral
neck fractures basically fall into two categories: internal fixation
or arthroplasty (either hemiarthroplasty or total hip arthroplasty).
Historically, the treatment option has been driven by a diagnosis-related approach
(non-displaced neck fractures versus displaced neck fractures).
More recently, the traditional paradigm has changed. Instead of
a diagnosis-related approach, it has become more of a patient-related
approach. Treatment options take in to consideration the patient’s age,
functional demands, and individual risk profile. A simple algorithm
can be helpful in terms of directing the treatment. Non-displaced
fractures, regardless of age of the patient, should be treated with
closed reduction and internal fixation. For displaced femoral neck fractures,
the treatment differs depending on the age of the patient. The younger
patient should be treated with urgent ORIF with the goal of an anatomic
reduction. For displaced femoral neck fractures in the elderly,
cognitive function should be determined. For those who are cognitively
functioning, total hip arthroplasty appears to be the best option.
In the cognitively dysfunctional, a bipolar hemiarthroplasty or
a total hip arthroplasty with use of larger heads (32 mm or 36 mm)
and/or constrained sockets are a viable option.
Total hip replacement (THR) still is a rare intervention
in many African countries. In Burkina Faso it is not performed on
a regular basis. A visiting programme for THR was started in a district
hospital with no previous relevant experience. In this paper we
present an analysis of the surgical technical problems and peri-operative
complications of 152 THRs in 136 patients and three bipolar hemiarthroplasties
in three patients undertaken in this new programme with limited
orthopaedic equipment. There were 86 male and 53 female patients
with a mean age of 49 years (21 to 78). We identified 77 intra-operative
technical problems in 51 operations. There were 24 peri-operative complications
in 21 patients, 17 of which were bony in nature. So far, ten revision
THRs have been performed in nine patients. Regular analysis of the technical problems and complications
was used to improve quality, and we identified patient selection
adapted to the local circumstances as important to avoid complications.
Our reflections on the problems encountered in initiating such a
programme may be of help to other teams planning similar projects. Cite this article:
We compared the clinical and radiological outcomes
of two cementless femoral stems in the treatment of patients with
a Garden III or IV fracture of the femoral neck. A total of 70 patients At final follow-up there were no statistically significant differences
between the short anatomical and the conventional stems with regard
to the mean Harris hip score (85.7 (66 to 100) Our study demonstrated that despite the poor bone quality in
these elderly patients with a fracture of the femoral neck, osseo-integration
was obtained in all hips in both groups. However, the incidence
of thigh pain, pulmonary microemboli and peri-prosthetic fracture
was significantly higher in the conventional stem group than in
the short stem group.
The aim of this study was to determine the comorbid risk factors for failure in young patients who undergo fixation of a displaced fracture of the femoral neck. We identified from a prospective database all such patients ≤ 60 years of age treated with reduction and internal fixation. The main outcome measures were union, failure of fixation, nonunion and the development of avascular necrosis. There were 122 patients in the study. Union occurred in 83 patients (68%) at a mean follow-up of 58 months (18 to 155). Complications occurred in 39 patients (32%) at a mean of 11 months (0.5 to 39). The rate of nonunion was 7.4% (n = 9) and of avascular necrosis was 11.5% (n = 14). Failures were more common in patients over 40 years of age (p = 0.03). Univariate analysis identified that delay in time to fixation (>
24 hours), alcohol excess and pre-existing renal, liver or respiratory disease were all predictive of failure (all p <
0.05). Of these, alcohol excess, renal disease and respiratory disease were most predictive of failure on multivariate analysis. Younger patients with fractures of the femoral neck should be carefully evaluated for comorbidities that increase the risk of failure after reduction and fixation. In patients with a history of alcohol abuse, renal or respiratory disease, arthroplasty should be considered as an alternative treatment.
The October 2014 Trauma Roundup360 looks at: proximal humeral fractures in children; quadrilateral surface plates in transverse acetabular fractures; sleep deprivation and poor outcomes in trauma; bipolar hemiarthroplasty; skeletal traction; forefoot fractures; telemedicine in trauma; ketamine infusion for orthopaedic injuries; and improved functional outcomes seen with trauma networks.
Patient safety is a critical issue in elective
total joint replacement surgery. Identifying risk factors that might
predict complications and intensive care unit (ICU) admission proves instrumental
in reducing morbidity and mortality. The institution’s experience
with risk stratification and pre-operative ICU triage has resulted
in a reduction in unplanned ICU admissions and post-operative complications
after total hip replacement. The application of the prediction tools
to total knee replacement has proven less robust so far. This work
also reviews areas for future research in patient safety and cost
containment. Cite this article:
The increasing prevalence of osteoporosis in
an ageing population has contributed to older patients becoming
the fastest-growing group presenting with acetabular fractures.
We performed a systematic review of the literature involving a number
of databases to identify studies that included the treatment outcome
of acetabular fractures in patients aged >
55 years. An initial
search identified 61 studies; after exclusion by two independent
reviewers, 15 studies were considered to meet the inclusion criteria.
All were case series. The mean Coleman score for methodological
quality assessment was 37 (25 to 49). There were 415 fractures in
414 patients. Pooled analysis revealed a mean age of 71.8 years
(55 to 96) and a mean follow-up of 47.3 months (1 to 210). In seven
studies the results of open reduction and internal fixation (ORIF)
were presented: this was combined with simultaneous hip replacement
(THR) in four, and one study had a mixture of these strategies.
The results of percutaneous fixation were presented in two studies,
and a single study revealed the results of non-operative treatment. With fixation of the fracture, the overall mean rate of conversion
to THR was 23.1% (0% to 45.5%). The mean rate of non-fatal complications
was 39.8% (0% to 64%), and the mean mortality rate was 19.1% (5%
to 50%) at a mean of 64 months (95% confidence interval 59.4 to
68.6; range 12 to 143). Further data dealing with the classification
of the fracture, the surgical approach used, operative time, blood
loss, functional and radiological outcomes were also analysed. This study highlights that, of the many forms of treatment available
for this group of patients, there is a trend to higher complication
rates and the need for further surgery compared with the results
of the treatment of acetabular fractures in younger patients. Cite this article:
We analysed the effects of commonly used medications
on human osteoblastic cell activity in vitro, specifically proliferation
and tissue mineralisation. A list of medications was retrieved from
the records of patients aged >
65 years filed in the database of
the largest health maintenance organisation in our country (>
two
million members). Proliferation and mineralisation assays were performed
on the following drugs: rosuvastatin (statin), metformin (antidiabetic),
metoprolol (β-blocker), citalopram (selective serotonin reuptake
inhibitor [SSRI]), and omeprazole (proton pump inhibitor (PPI)).
All tested drugs significantly stimulated DNA synthesis to varying
degrees, with rosuvastatin 5 µg/ml being the most effective among
them (mean 225% ( Cite this article:
We report the results of six trauma and orthopaedic
projects to Kenya in the last three years. The aims are to deliver both
a trauma service and teaching within two hospitals; one a district
hospital near Mount Kenya in Nanyuki, the other the largest public
hospital in Kenya in Mombasa. The Kenya Orthopaedic Project team
consists of a wide range of multidisciplinary professionals that
allows the experience to be shared across those specialties. A follow-up
clinic is held three months after each mission to review the patients.
To our knowledge there are no reported outcomes in the literature
for similar projects. A total of 211 operations have been performed and 400 patients
seen during the projects. Most cases were fractures of the lower
limb; we have been able to follow up 163 patients (77%) who underwent
surgical treatment. We reflect on the results so far and discuss
potential improvements for future missions.
The outcome after total hip replacement has improved
with the development of surgical techniques, better pain management
and the introduction of enhanced recovery pathways. These pathways
require a multidisciplinary team to manage pre-operative education,
multimodal pain control and accelerated rehabilitation. The current economic
climate and restricted budgets favour brief hospitalisation while
minimising costs. This has put considerable pressure on hospitals
to combine excellent results, early functional recovery and shorter
admissions. In this review we present an evidence-based summary of some common
interventions and methods, including pre-operative patient education,
pre-emptive analgesia, local infiltration analgesia, pre-operative
nutrition, the use of pulsed electromagnetic fields, peri-operative
rehabilitation, wound dressings, different surgical techniques, minimally
invasive surgery and fast-track joint replacement units. Cite this article:
Things have not been quiet in the Cochrane Collaboration in the four months since the last 'Cochrane Corner', with the publication of six new or updated reviews summarised here, all conducted with the bulletproof Collaboration's methodology representing the pinnacle of evidence relevant to orthopaedic surgeons.
With the established success of the National
Joint Registry and the emergence of a range of new national initiatives for
the capture of electronic data in the National Health Service, orthopaedic
surgery in the United Kingdom has found itself thrust to the forefront
of an information revolution. In this review we consider the benefits
and threats that this revolution poses, and how orthopaedic surgeons
should marshal their resources to ensure that this is a force for
good.

The August 2013 Hip &
Pelvis Roundup360 looks at: are we getting it right first time?; tantalum augments in revision hip surgery; lower wear in dual mobility?; changing faces changes outcomes; synovial fluid aspiration in MOM hips; taper disease: the new epidemic of hip surgery; the super-obese and THR; and whether well fixed stems can remain in infected hips
For over a decade, bisphosphonate administration
has evolved and become the cornerstone of the prevention and treatment
of fragility fractures. Millions of post-menopausal women have relied
on, and continue to depend on, the long-acting, bone density-maintaining
pharmaceutical drug to prevent low-energy fractures. In return,
we have seen the number of fragility fractures decrease, along with
associated costs and emotional benefits. However, with any drug,
there are often concerns with side effects and complications, and
this unique drug class is seeing one such complication in atypical
subtrochanteric femoral fracture, counterproductive to that which
it was designed to prevent. This has created concern over long-term
bisphosphonate administration and its potential link to these atypical
fractures. There is controversial evidence surrounding such a definitive
link, and no protocol for managing these fractures. This review offers the latest information regarding this rare
but increasingly controversial adverse effect and its potential
connection to one of the most successful forms of treatment that
is available for the management of fragility fractures.
This conversation represents an attempt by several
arthroplasty surgeons to critique several abstracts presented over
the last year as well as to use them as a jumping off point for trying
to figure out where they fit in into our current understanding of
multiple issues in modern hip and knee arthroplasty.
