Total Hip Arthroplasty in Lubumbashi (DR Congo), Outcomes in a Resource-Limited Setting.
Article in Journal of orthopaedic case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Total hip arthroplasty (THA) is well established in high-income countries but remains challenging in sub-Saharan Africa due to limited implant availability, inadequate infrastructure, and financial constraints. This study presents a 7 year experience of THA in Lubumbashi, Democratic Republic of Congo, focusing on both clinical outcomes and the strategies developed to overcome local challenges. Materials and Methods: We retrospectively analyzed 60 THAs performed on 58 patients (mean age 53.8 years) between 2017 and 2024 at Medpark Clinic. The main indication was femoral head osteonecrosis (71.6%), including 11 cases in patients with sickle cell disease. All procedures used a transgluteal approach, with implant choice adapted to bone quality and availability. Rehabilitation emphasized early mobilization despite limited physiotherapy resources. Results: At a mean follow-up of 4.5 years, functional outcomes improved markedly, with the Postel-Merle d'Aubigné score rising from 6.4 preoperatively to 16.2 at six months. Excellent or good results were achieved in 90.7% of cases. Complications occurred in 17.2% of patients, including dislocations (6.6%), infections (6.6%), periprosthetic fractures (3.3%), aseptic loosening (3.3%), one pulmonary embolism (1.6 %), and two deaths (3.3%). Challenges and solutions: Barriers included high implant costs and irregular supply, addressed through long-term supplier partnerships and flexible payment plans. Infection control limitations were mitigated by strict asepsis protocols, povidone-iodine lavage, and selective use of antibiotic-loaded cement. In the absence of formal rehabilitation centers, structured patient and family education with early weight-bearing protocols facilitated recovery. Socioeconomic barriers were partially alleviated by forfait-based pricing and community financing mechanisms. Conclusion: Despite significant structural and economic constraints, THA can be safely and effectively implemented in resource-limited African settings when supported by careful surgical planning, tailored implant strategies, strict infection control, and innovative solutions to financial and logistical barriers.
