Dual mobility total hip replacement: a 15-year experience in Burkina Faso

Abstract

To report our 15 years of experience in dual mobility total hip replacement (THR) in Burkina Faso through a Franco-Burkinabè relief organization. A retrospective study spanning from 2004 to 2018 was held in a private facility. All dual mobility THR cases with at least one year of follow-up time were included. The survey used a questionnaire, and data were analyzed with statistical software (Stata® v.13). A total of 145 primary THR in 129 patients were included in disabled young patients. There was 60.46% of males (n=78) with a mean age of 44.57 years (SD=12.43). The mean etiologies were avascular necrosis of the hip (n=84), followed by childhood chronic arthritis sequalae (n=24, 16.55%) and trauma sequalae (n=13, 8.97%). All prostheses were metal-on-polyethylene from Zimmer-Biomet®. It was usually small sizes with 48 mm (females) and 50 mm (males) cups, stem 1 (female) and 3 (males). After 2.70 years (SD=2.66) of mean follow-up times, results were good despite a high rate of revision (n=10, 6.89%) due to infections and implant malposition. THR practice might be encouraged in developing countries. The dual mobility concept is adapted to sociological activities. High duration implants and cost limitation is mandatory for the replacement joints diffusion.
