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.

Perthes' disease is thought to be rare in black children but no figures of incidence have previously been available. A search was therefore made for cases of the disease occurring in the Eastern Cape during the five-year period 1975 to 1979. Of 55 cases found, 38 were in white children, 11 in children of mixed ancestry ("coloured" children) and six in black children. The annual incidence in white children aged 14 years and under was 10.8 per 100 000, in coloured children 1.7 per 100 000, and in black children 0.45 per 100 000. In all races the incidence in the metropolitan area of Port Elizabeth was roughly twice that in the rural part of the region. The reason for the low incidence in coloured and black children is not known but various factors are suggested.

There are 33 million people worldwide currently infected with human immunodeficiency virus (HIV). This complex disease affects many of the processes involved in wound and fracture healing, and there is little evidence available to guide the management of open fractures in these patients. Fears of acute and delayed infection often inhibit the use of fixation, which may be the most effective way of achieving union. This study compared fixation of open fractures in HIV-positive and -negative patients in South Africa, a country with very high rates of both HIV and high-energy trauma. A total of 133 patients (33 HIV-positive) with 135 open fractures fulfilled the inclusion criteria. This cohort is three times larger than in any similar previously published study. The results suggest that HIV is not a contraindication to internal or external fixation of open fractures in this population, as HIV is not a significant risk factor for acute wound/implant infection. However, subgroup analysis of grade I open fractures in patients with advanced HIV and a low CD4 count (< 350) showed an increased risk of infection; we suggest that grade I open fractures in patients with advanced HIV should be treated by early debridement followed by fixation at an appropriate time

Dysplasia of the hip is almost unknown in the Bantu peoples of Africa, except in cases of arthrogryposis and in those with partly European ancestry. Evidence is produced to show that the importance of intrinsic genetic factors in hip dysplasia far outweighs that of the extrinsic factors. These are of great importance only if allowed to act on a hip in which genetic factors have already determined dysplasia. Evidence is also produced to contradict the theory that the "piggyback" carrying method used by Bantu mothers is the reason for the immunity from dysplasia of the hip. The absence of "primary" osteoarthritis of the hip is noted, and the range of hip disorders leading to "secondary" osteoarthritis in the adult African is compared with that in the adult European. Three patients are described, one in each of the groups mentioned above, the third having an isolated "typical" congenital dislocation of one hip. The methods of study used were enquiry into obstetric history and into carrying methods, and arthrography to confirm clinical findings. The experience of other surgeons working in Africa is recorded

In Africa the amount of joint replacement surgery is increasing, but the indications for operation and the age of the patients are considerably different from those in the developed world. New centres with variable standards of care and training of the surgeons are performing these procedures and it is important that a proper audit of this work is undertaken. In Malawi, we have pioneered a Registry which includes all joint replacements that have been carried out in the country. The data gathered include the age, gender, indication for operation, the prosthesis used, the surgical approach, the use of bone graft, the type of cement, pressurising systems and the thromboprophylaxis used. All patients have their clinical scores recorded pre-operatively and then after three and six months and at one year. Before operation all patients are counselled and on consent their HIV status is established allowing analysis of the effect of HIV on successful joint replacement. To date, 73 total hip replacements (THRs) have been carried out in 58 patients by four surgeons in four different hospitals. The most common indications for THR were avascular necrosis (35 hips) and osteoarthritis (22 hips). The information concerning 20 total knee replacements has also been added to the Registry

Musculoskeletal diseases are having a growing impact worldwide. It is therefore crucial to have an evidence base to most effectively and efficiently implement future health services across different healthcare systems. International trials are an opportunity to address these challenges and have many potential benefits. They are, however, complex to set up and deliver, which may impact on the efficient and timely delivery of a project. There are a number of models of how international trials are currently being delivered across a range of orthopaedic patient populations, which are discussed here. The examples given highlight that the key to overcoming these challenges is the development of trusted and equal partnerships with collaborators in each country. International trials have the potential to address a global burden of disease, and in turn optimize the benefit to patients in the collaborating countries and those with similar health services and care systems.

1. A primary subacute type of staphylococcal osteomyelitis has been described. It is the commonest form of osteomyelitis seen in East Africa, and the incidence appears to be increasing in Great Britain. 2. A review of the literature indicates that this is not a new disease but that in the past there has been some confusion in terminology. 3. The causative organism is a coagulase positive staphylococcus, but in a few instances a coagulase negative one has been isolated. The staphylococcus is thought to be of reduced virulence and in East Africa it is likely that the population has acquired an increased resistance to the staphylococcus. 4. Two radiologically distinct groups are recognised, depending on whether a bone abscess is present or not. In the first group there are two types of localised abscesses: the familiar Brodie's lesion and the less well recognised large bone abscess that occurs in the metaphysis of a long bone. While the pathology of the two types is similar, the radiological features are quite distinct. The lesions in the second group are characterised by extensive diaphysial changes, with or without metaphysial involvement, and an obvious abscess cannot usually be demonstrated. 5. The main clinical features are the long history, often weeks or months, before diagnosis; insignificant or absent general reaction to the infection and minimum physical signs. 6. Vertebral body osteomyelitis in adults is included because it generally presents as a subacute infection; the difficulties in distinguishing it from a tuberculous infection are outlined. 7. The most useful diagnostic aids are the staphylococcal antibody titres (especially in vertebral infections) and the erythrocyte sedimentation rate. A limited surgical exposure is usually required if the causative organism is to be isolated and empirical antibiotic therapy is to be avoided. The total and differential white blood count are so often normal in these patients that they are considered to be of no diagnostic value. 8. Curettage and local antibiotics together will cure the localised bone abscess. Other lesions may be effectively treated by systemic antibiotics alone, but in the later stages removal of sequestra and infected granulation tissue may be necessary. In this instance it is essential to make a planned incision and to cut a window in the bone large enough to expose the whole of the lesion; primary suture of the wound is advocated

Aims

To analyze whether the addition of risk-based criteria to clinical examination-based selective ultrasound screening would increase the rates of early detected cases of developmental dysplasia of the hip (DDH) and decrease the rate of late detected cases.

Aims

This study aims to identify the top unanswered research priorities in the field of knee surgery using consensus-based methodology.

Aims

Children with spinal dysraphism can develop various musculoskeletal deformities, necessitating a range of orthopaedic interventions, causing significant morbidity, and making considerable demands on resources. This systematic review aimed to identify what outcome measures have been reported in the literature for children with spinal dysraphism who undergo orthopaedic interventions involving the lower limbs.

Aims

The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI).

The Jaipur foot was developed for barefoot amputees by Professor P. K. Sethi. He used local artisans and readily available materials. The prosthesis was cheap and could be made in one hour. It enabled amputees to work in rural conditions, muddy and wet fields and to climb trees. It has been widely used in India, South East Asia and Africa, where local variations to the design have now been made

The distinctive clinical characteristics of ainhum conforming to classical descriptions, as seen in 100 patients in Central and West Africa, are briefly reviewed, special emphasis being laid on those features that serve to differentiate ainhum from other conditions that may in some respects resemble it

1. A large Caucasian kindred in South Africa are affected by a previously undescribed inherited deformity of the hands and feet called digito-talar dysmorphism. 2. The principal features of digito-talar dysmorphism are flexion deformities, narrowing and ulnar deviation of the fingers. The thumb may be held in an abnormal position by a soft-tissue web. Rocker-bottom foot may develop, due to vertical talus. The facies is normal and the mentality is unimpaired. 3. The general health is good but orthopaedic measures may be needed for function and cosmesis. 4. The condition is transmitted as an autosomal dominant trait, with varying clinical expression of the abnormal gene

The prevalence of HIV infection in East Africa has increased rapidly in recent years. We made a prospective study of the incidence of HIV-seropositivity in patients undergoing orthopaedic procedures in a large district hospital in Bulawayo, Zimbabwe. One of our aims was to determine whether a clinically-based screening programme, derived from the Centre for Disease Control classification of HIV infection, could identify high-risk individuals before surgery. During a 3-month period, 76 patients were tested, and 12 were HIV-positive (16%). Only two of these patients (17%) had clinical features associated with HIV infection; ten (83%) were entirely asymptomatic. Our results indicate that preoperative clinical screening is unlikely to be successful in identifying seropositive patients before routine surgery

During the course of a nation-wide survey of patients with bone and joint deformities, twenty-six individuals with arthrogryposis multiplex congenita, in the narrow and precise sense of the term, were investigated. No patient was more than twenty-four years of age. However, on a basis of the figures of population, it can be estimated that 21-0 +/- 6-5 older affected individuals should have been encountered. Furthermore, there was a relative excess of younger children. The series was reasonably unbiased, and as arthrogryposis is non-lethal the deficiency of affected adults is an anomalous finding. It is tentatively suggested that arthrogryposis might result from the intra-uterine influence of an unknown environmental agent which has been present in South Africa for only a limited period of time. Detection of this factor could be an important step in the prevention of the disease

Total hip replacement using an alumina head and socket and a titanium alloy stem is evaluated in a series of patients under 50 years of age. Between April 1977 and December 1986, 86 such replacements were performed in 75 patients, but mainly because patients had difficulty travelling from Africa, only 71 hips were followed up adequately; of these, 56 were primary procedures and 15 revisions. Survivorship analysis showed that 98% of the prostheses were retained for 10 years. On clinical and radiological examination 51 of the 71 hips were stable and acceptable, 15 had radiological changes on the acetabular side, and one on the femoral side; four other cases had clinical and radiological changes suggesting impending failure, possibly because fixation of the socket was inadequate. There were no differences between the results of the primary procedures and those of revisions. In these young patients, the results seem better with alumina-on-alumina hips than with other varieties, possibly because of their remarkably low wear

1. Radiography of the spines of thirty-three West African patients recently recovered or dead from tetanus revealed vertebral fractures in nineteen. These fractures occurred most frequently in the fourth to eighth thoracic vertebrae. 2. The spines of 111 Nigerians from the same area of West Africa were examined, measurement of the areas and shape of the vertebral bodies carried out, and the proportional incidence of articular shelves and laminar spicules was calculated. 3. The upper mid-thoracic vertebral bodies are relatively long and narrow and have but little greater cross-sectional area than those immediately above them; possessing no neural arch supports to sustain longitudinal compressive forces in flexion, they are at greatest hazard during tetanic spasms. 4. Analyses of these factors and of the clinical features, together with experimental observations drawn from the literature, are used to explain the prevalence of upper mid-thoracic vertebral fractures as a complication of tetanus in West Africans, and in particular the greater degree of compression and higher incidence found in children. 5. Vertebral fracture is not usually an important complication of tetanus; it causes little pain, does not prolong the illness, gives rise to no permanent disability and has no effect on the mortality

The atlas of Greulich and Pyle for skeletal maturity and epiphyseal closure is widely used in many countries to assess skeletal age and to plan orthopaedic surgery. The data used to compile the atlas were collected from institutionalised American children in the 1950s. In order to determine whether the atlas was relevant to subSaharan Africa, we compared skeletal age, according to the atlas, with chronological age in 139 skeletally immature Malawian children and young adults with an age range from 1 year 11 months to 28 years 5 months. The height and weight of each patient were also measured in order to calculate the body mass index. The skeletal age of 119 patients (85.6%) was lower than the chronological age. The mean difference was 20.0 ± 24.1 months (t-test, p = 0.0049), and the greatest difference 100 months. The atlas is thus inaccurate for this group of children. The body mass index in 131 patients was below the normal range of 20 to 25 kg/m. 2. . The reasons for the low skeletal age in this group of children are discussed. Poor nutrition and chronic diseases such as malaria and diarrhoea which are endemic in Malawi are likely to be contributing factors. We did not find any correlation between the reduction in body mass index in our patients and the degree of retardation of skeletal age

Aims

To describe the clinical, radiological, and functional outcomes in patients with isolated congenital thoracolumbar kyphosis who were treated with three-column osteotomy by posterior-only approach.

Aims

Spinal deformity surgery carries the risk of neurological injury. Neurophysiological monitoring allows early identification of intraoperative cord injury which enables early intervention resulting in a better prognosis. Although multimodal monitoring is the ideal, resource constraints make surgeon-directed intraoperative transcranial motor evoked potential (TcMEP) monitoring a useful compromise. Our experience using surgeon-directed TcMEP is presented in terms of viability, safety, and efficacy.

Aims

HIV predisposes patients to opportunistic infections. However, with the establishment of Highly Active Anti-Retroviral Therapy (HAART), patients’ CD4 counts are maintained, as is a near normal life expectancy. This study aimed to establish the impact of HIV on the bacteriology of spondylodiscitis in a region in which tuberculosis (TB) is endemic, and to identify factors that might distinguish between them.

Tuberculosis (TB) remains endemic in many parts of the developing world and is increasingly seen in the developed world due to migration. A total of 1.3 million people die annually from the disease. Spinal TB is the most common musculoskeletal manifestation, affecting about 1 to 2% of all cases of TB. The coexistence of HIV, which is endemic in some regions, adds to the burden and the complexity of management.

This review discusses the epidemiology, clinical presentation, diagnosis, impact of HIV and both the medical and surgical options in the management of spinal TB.

Aims

The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of relapse and determines how clubfoot is assessed at presentation, correction, and relapse.

Aims

The aim of this study was to describe the epidemiology of closed isolated fractures of the femoral shaft in children, and to compare the treatment and length of stay (LOS) between major trauma centres (MTCs) and trauma units (TUs) in England.

The Unified Classification System (UCS) emphasises the key principles in the assessment and management of peri-prosthetic fractures complicating partial or total joint replacement.

We tested the inter- and intra-observer agreement for the UCS as applied to the pelvis and femur using 20 examples of peri-prosthetic fracture in 17 patients. Each subtype of the UCS was represented by at least one case. Specialist orthopaedic surgeons (experts) and orthopaedic residents (pre-experts) assessed reliability on two separate occasions.

For the pelvis, the UCS showed inter-observer agreement of 0.837 (95% confidence intervals (CI) 0.798 to 0.876) for the experts and 0.728 (95% CI 0.689 to 0.767) for the pre-experts. The intra-observer agreement for the experts was 0.861 (95% CI 0.760 to 0.963) and 0.803 (95% 0.688 to 0.918) for the pre-experts. For the femur, the UCS showed an inter-observer kappa value of 0.805 (95% CI 0.765 to 0.845) for the experts and a value of 0.732 (95% CI 0.690 to 0.773) for the pre-experts. The intra-observer agreement was 0.920 (95% CI 0.867 to 0.973) for the experts, and 0.772 (95% CI 0.652 to 0.892) for the pre-experts. This corresponds to a substantial and ‘almost perfect’ inter- and intra-observer agreement for the UCS for peri-prosthetic fractures of the pelvis and femur.

We hope that unifying the terminology of these injuries will assist in their assessment, treatment and outcome.

We reviewed the clinical details and radiographs of 52 patients with ballistic fractures of the femur admitted to the International Committee of the Red Cross Hospital in Kenya (Lopiding), who had sustained injuries in neighbouring Sudan. In all cases there had been a significant delay in the initial surgery (> 24 hours), and all patients were managed without stabilisation of the fracture by internal or external fixation.

Of the 52 patients, three required an amputation for persisting infection of the fracture site despite multiple debridements. A further patient was treated by an excision arthroplasty of the hip, but this was carried out at the initial operation as a part of the required debridement.

All of the remaining 48 fractures healed. Four patients needed permanent shoe adaptation because of limb shortening of functional significance.

Although we do not advocate delaying treatment or using traction instead of internal or external fixation, we have demonstrated that open femoral fractures can heal despite limited resources.

The purpose of this study was to determine the annual incidence of Perthes’ disease in Korea and compare this with other populations. A survey identified all newly diagnosed children with Perthes’ disease aged 14 years or younger in South Honam, Korea, between January 1999 and December 2001. A total of 84 children were included: 29 in 1999, 28 in 2000 and 27 in 2001. The mean annual incidence was 3.8 per 100 000. This is similar to that reported in other Asian countries, but higher than in black populations and lower than in Caucasians.

In May 2012, in airports across the globe, seven orthopaedic surgeons bravely said goodbye to their loved ones, and slowly turned towards their respective aircraft. Filled with expectation and mild trepidation they stepped into the unknown… the ABC fellowship of 2012.

In this retrospective observational cohort study, we describe 17 patients out of 1775 treated for various fractures who developed mycobacterium tuberculosis (MTB) infection after surgery. The cohort comprised 15 men and two women with a mean age of 40 years (24 to 70). A total of ten fractures were open and seven were closed. Of these, seven patients underwent intramedullary nailing of a fracture of the long bone, seven had fractures fixed with plates, two with Kirschner-wires and screws, and one had a hemiarthroplasty of the hip with an Austin Moore prosthesis. All patients were followed-up for two years. In all patients, the infection resolved, and in 14 the fractures united. Nonunion was seen in two patients one of whom underwent two-stage total hip arthroplasty (THA) and the other patient was treated using excision arthoplasty. Another patient was treated using two-stage THA. With only sporadic case reports in the literature, MTB infection is rarely clinically suspected, even in underdeveloped and developing countries, where pulmonary and other forms of TB are endemic. In developed countries there is also an increased incidence among immunocompromised patients. In this paper we discuss the pathogenesis and incidence of MTB infection after surgical management of fractures and suggest protocols for early diagnosis and management.

The incidence of acute and chronic conditions of the tendo Achillis appear to be increasing. Causation is multifactorial but the role of inherited genetic elements and the influence of environmental factors altering gene expression are increasingly being recognised. Certain individuals’ tendons carry specific variations of genetic sequence that may make them more susceptible to injury. Alterations in the structure or relative amounts of the components of tendon and fine control of activity within the extracellular matrix affect the response of the tendon to loading with failure in certain cases.

This review summarises present knowledge of the influence of genetic patterns on the pathology of the tendo Achillis, with a focus on the possible biological mechanisms by which genetic factors are involved in the aetiology of tendon pathology. Finally, we assess potential future developments with both the opportunities and risks that they may carry.

Little information is available about several important aspects of the treatment of melioidosis osteomyelitis and septic arthritis.

We undertook a retrospective review of 50 patients with these conditions in an attempt to determine the effect of location of the disease, type of surgical intervention and duration of antibiotic treatment on outcome, particularly complications and relapse.

We found that there was a 27.5% risk of osteomyelitis of the adjacent bone in patients with septic arthritis in the lower limb. Patients with septic arthritis and osteomyelitis of an adjacent bone were in hospital significantly longer (p = 0.001), needed more operations (p = 0.031) and had a significantly higher rate of complications and re-presentation (p = 0.048).

More than half the patients (61%), most particularly those with multifocal bone and joint involvement, and those with septic arthritis and osteomyelitis of an adjacent bone who were treated operatively, needed more visits to theatre.

This study assessed the frequency of acute injury to the spinal cord in Irish Rugby over a period of ten years, between 1995 and 2004. There were 12 such injuries; 11 were cervical and one was thoracic. Ten occurred in adults and two in schoolboys. All were males playing Rugby Union and the mean age at injury was 21.6 years (16 to 36). The most common mechanism of injury was hyperflexion of the cervical spine and the players injured most frequently were playing at full back, hooker or on the wing. Most injuries were sustained during the tackle phase of play. Six players felt their injury was preventable. Eight are permanently disabled as a result of their injury.

The Thomas splint is a common piece of equipment in emergency departments and orthopaedic units in hospitals worldwide. Its basic design has changed little since its first description by Hugh Owen Thomas was published in 1875. We have reviewed the origins of the Thomas splint as a means of correction of deformities of the lower limb and its evolution through both World Wars into an essential item for the management of trauma of the lower limb.

This article presents an overview of mycetoma and offers guidelines for orthopaedic surgeons who may be involved in the care of patients with this condition.

We report the short-term follow-up, functional outcome and incidence of early and late infection after total hip replacement (THR) in a group of HIV-positive patients who do not suffer from haemophilia or have a history of intravenous drug use. A total of 29 patients underwent 43 THRs, with a mean follow-up of three years and six months (five months to eight years and two months). There were ten women and 19 men, with a mean age of 47 years and seven months (21 years to 59 years and five months). No early (< 6 weeks) or late (> 6 weeks) complications occurred following their THR. The mean pre-operative Harris hip score (HHS) was 27 (6 to 56) and the mean post-operative HHS was 86 (73 to 91), giving a mean improvement of 59 points (p = < 0.05, Student’s t-test). No revision procedures had been undertaken in any of the patients, and none had any symptoms consistent with aseptic loosening. This study demonstrates that it is safe to perform THR in HIV-positive patients, with good short-term functional outcomes and no apparent increase in the risk of early infection.

We compared early post-operative rates of wound infection in HIV-positive and -negative patients presenting with open tibial fractures managed with surgical fixation.

The wounds of 84 patients (85 fractures), 28 of whom were HIV positive and 56 were HIV negative, were assessed for signs of infection using the ASEPIS wound score. There were 19 women and 65 men with a mean age of 34.8 years. A total of 57 fractures (17 HIV-positive, 40 HIV-negative) treated with external fixation were also assessed using the Checkett score for pin-site infection. The remaining 28 fractures were treated with internal fixation. No significant difference in early post-operative wound infection between the two groups of patients was found (10.7% (n = 3) vs 19.6% (n = 11); relative risk (RR) 0.55 (95% confidence interval (CI) 0.17 to 1.8); p = 0.32). There was also no significant difference in pin-site infection rates (17.6% (n = 3) vs 12.5% (n = 5); RR 1.62 (95% CI 0.44 to 6.07); p = 0.47).

The study does not support the hypothesis that HIV significantly increases the rate of early wound or pin-site infection in open tibial fractures. We would therefore suggest that a patient’s HIV status should not alter the management of open tibial fractures in patients who have a CD4 count > 350 cells/μl.

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.

We have investigated the annual incidence of Perthes’ disease in Dumfries and Galloway (Southwest Scotland), in relation to the population density and socio-economic status. The incidence of Perthes’ disease in rural Scotland is comparable with that in urban areas (15.4 per 100 000). There was a direct association between the incidence of Perthes’ disease and deprivation scores, with the highest incidence in the most deprived areas. A higher incidence of Perthes’ disease was noted in areas with a lower population density compared with those with a higher density. We found no correlation between population density and deprivation scores for individual electoral wards within the region.

Anthrax is extremely rare in the western world but is endemic to areas of south and central Asia. In early 2010 an outbreak was identified in heroin-injecting intravenous drug users in the United Kingdom and Europe. Afghanistan is currently the principal source of heroin which reaches the United Kingdom. When anthrax occurs, cutaneous disease accounts for over 95% of cases. At least 47 cases with 13 deaths have been confirmed so far. We present three cases presenting during this time with marked swelling, one resulting in compartment syndrome but all with an absence of the expected cutaneous appearances.

We suggest that rather than cutaneous anthrax, these patients represent a new subcutaneous presentation of anthrax.
