RESUMO
INTRODUCTION: Hip arthroplasty and revision surgery are growing exponentially in OECD countries. In developing countries, it is an infrequent intervention and its practice is limited. It is exposed to a higher rate of infectious and mechanical failures than in developed countries. The aim of the actual study is to provide a review of the literature on total hip arthroplasty series in sub-Saharan Africa followed by an overview of the interest and perspectives of the use of dual mobility (DM) cups. MATERIALS AND METHODS: Scopus, EMBASE, Medline, PubMed, and Safoonline databases were searched including papers published at any date. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. All papers from South Africa were excluded. RESULTS: We identified 22 series of total hip arthroplasty in 14 SSA countries. The practice of total hip arthroplasty is not very widespread. The cups used are mostly conventional implants, and complications (mechanical and infectious) are frequent. DISCUSSION: The interest for the use of dual mobility cups in sub-Saharan Africa can be summarized in two points: mechanical and socio-economical. Dual mobility cups provide more mechanical stability and a reduction in the overall cost of treatment by reducing the rate of complications. These prospects will make it possible to evaluate this medical device in the long term in a hostile environment conductive to complications. CONCLUSION: The use of dual mobility deserves to be developed in African settings.
