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:
Non-traumatic osteonecrosis of the femoral head
is a potentially devastating condition, the prevalence of which
is increasing. Many joint-preserving forms of treatment, both medical
and surgical, have been developed in an attempt to slow or reverse
its progression, as it usually affects young patients. However, it is important to evaluate the best evidence that is
available for the many forms of treatment considering the variation
in the demographics of the patients, the methodology and the outcomes
in the studies that have been published, so that it can be used
effectively. The purpose of this review, therefore, was to provide an up-to-date,
evidence-based guide to the management, both non-operative and operative,
of non-traumatic osteonecrosis of the femoral head. Cite this article:
The aim of this study was to compare the pain caused by the application
of a tourniquet after exsanguination of the upper limb with that
occurring after simple elevation. We used 26 healthy volunteers (52 arms), each of whom acted as
their own matched control. The primary outcome measure was the total pain experienced by
each volunteer while the tourniquet was inflated for 20 minutes.
This was calculated as the area under the pain curve for each individual
subject. Secondary outcomes were pain at each time point; the total
pain experienced during the recovery phase; the ability to tolerate the
tourniquet and the time for full recovery after deflation of the
tourniquet. Aims
Patients and Methods
From a global point of view, chronic haematogenous osteomyelitis in children remains a major cause of musculoskeletal morbidity. We have reviewed the literature with the aim of estimating the scale of the problem and summarising the existing research, including that from our institution. We have highlighted areas where well-conducted research might improve our understanding of this condition and its treatment.
A delay in the diagnosis of paediatric acute
and subacute haematogenous osteomyelitis can lead to potentially devastating
morbidity. There are no definitive guidelines for diagnosis, and
recommendations in the literature are generally based on expert
opinions, case series and cohort studies. All articles in the English literature on paediatric osteomyelitis
were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the
Cochrane Library and reference lists. A total of 1854 papers were
identified, 132 of which were examined in detail. All aspects of
osteomyelitis were investigated in order to formulate recommendations. On admission 40% of children are afebrile. The tibia and femur
are the most commonly affected long bones. Clinical examination,
blood and radiological tests are only reliable for diagnosis in
combination. Most studies were retrospective and there is a need for large,
multicentre, randomised, controlled trials to define protocols for
diagnosis and treatment. Meanwhile, evidence-based algorithms are
suggested for accurate and early diagnosis and effective treatment.
We examined 204 children (137 boys and 67 girls) aged 12 years and under with septic arthritis. Their mean age was 31.1 months (1 to 144; SD 41.6). The most common joints affected were the knees and shoulders. Joints in the upper limb were affected more often in younger children and in the lower limb in those who were older. The mean age for an infection was 12 months in the shoulder and 73 months in the hip. The most common organisms cultured were species of Salmonella.
This prospective study evaluates the role of new laboratory markers in the diagnosis of deep implant infection in 78 patients (41 men and 37 women) with a revision total knee or hip replacement. The mean age at the time of operation was 64.0 years (19 to 90). Intra-operative cultures showed that 21 patients had a septic and 57 an aseptic total joint replacement. The white blood cell count, the erythrocyte sedimentation rate and levels of C-reactive protein, interleukin-6, procalcitonin and tumour necrosis factor (TNF)-α were measured in blood samples before operation. The diagnostic cut-off values were determined by Received Operating Characteristic curve analysis. C-reactive protein (>
3.2 md/dl) and interleukin-6 (>
12 pg/ml) have the highest sensitivity (0.95). Interleukin-6 is less specific than C-reactive protein (0.87 The combination of C-reactive protein and interleukin-6 measurement provide excellent screening tests for infection of a deep implant. A highly specific marker such as procalcitonin and pre-operative aspiration of the joint might be useful in identifying patients with true positive C-reactive protein and/or interleukin-6 levels.
