Chris Lavy is an orthopaedic surgeon in Oxford (UK) who lived and worked in Malawi for ten years. There he helped build an orthopaedic hospital and research unit. He was also one of the founders of COSECSA, the regional college of surgeons for East and Central
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:
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.
Aims. The aim of this study is to determine the predictors of overall survival (OS) and predictive factors of poor prognosis of conventional high-grade osteosarcoma of the limbs in a single-centre in South
Aims. Preprint servers allow authors to publish full-text manuscripts or interim findings prior to undergoing peer review. Several preprint servers have extended their services to biological sciences, clinical research, and medicine. The purpose of this study was to systematically identify and analyze all articles related to Trauma & Orthopaedic (T&O) surgery published in five medical preprint servers, and to investigate the factors that influence the subsequent rate of publication in a peer-reviewed journal. Methods. All preprints covering T&O surgery were systematically searched in five medical preprint servers (medRxiv, OSF Preprints, Preprints.org, PeerJ, and Research Square) and subsequently identified after a minimum of 12 months by searching for the title, keywords, and corresponding author in Google Scholar, PubMed, Scopus, Embase, Cochrane, and the Web of Science. Subsequent publication of a work was defined as publication in a peer-reviewed indexed journal. The rate of publication and time to peer-reviewed publication were assessed. Differences in definitive publication rates of preprints according to geographical origin and level of evidence were analyzed. Results. The number of preprints increased from 2014 to 2020 (p < 0.001). A total of 38.6% of the identified preprints (n = 331) were published in a peer-reviewed indexed journal after a mean time of 8.7 months (SD 5.4 (1 to 27)). The highest proportion of missing subsequent publications was in the preprints originating from
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

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.

A number of anti-retroviral therapies (ART) have been implicated in potentially contributing to HIV-associated bone disease. The aim of this study was to evaluate the effect of combination ART on the fracture healing process. A total of 16 adult male Wistar rats were randomly divided into two groups (n = eight each): Group 1 was given a combination of Tenfovir 30 mg, Lamivudine 30 mg, and Efavirenz 60 mg per day orally, whereas Group 2 was used as a control. After one week of medication preload, all rats underwent a standardized surgical procedure of mid-shaft tibial osteotomy fixed by intramedullary nail with no gap at the fracture site. Progress in fracture healing was monitored regularly for eight weeks. Further evaluations were carried out after euthanasia by micro-CT, mechanically and histologically. Two blinded orthopaedic surgeons used the Radiological Union Scoring system for the Tibia (RUST) to determine fracture healing.Aims
