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

To report our 15 years of experience in dual mobility total hip replacement (THR) in Burkina Faso through a Franco-Burkinabé 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.

Use of dual mobility cups for total hip arthroplasty in sub-Saharan Africa: interest and perspectives.

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.

Focus on interlocking intramedullary nailing without fluoroscopy in resource-limited settings: strategies, outcomes, and outlook.

INTRODUCTION: Closed static interlocking nailing with c-arm guidance is the standard procedure for the treatment of closed diaphyseal fractures. In low-income settings, it is still very difficult to carry out such procedures because of few or absent image intensifiers (c-arm) despite the necessity. Authors provide a review of the literature on interlocking intramedullary nailing without fluoroscopy in resource-limited settings, followed by strategies, outcomes, and outlook. MATERIALS AND METHOD: A comprehensive search of the PubMed, Web of Science, Embase, and Cochrane Library databases was performed with the help of a biomedical information specialist. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. RESULTS: We identified 15 series of interlocking intramedullary nailing without fluoroscopy in resource-limited settings. All papers focused on the care for long bones (humerus, femur, tibia). All studies discussed the quality of the nailing operative procedure. The entry point was described in five series; the nail insertion in the proximal and distal medullary canal was good in all studies. The distal locking was missed between 0 and 27%. DISCUSSION: Intraoperative strategies depend on the type of bone affected, the opening of the fracture site, the fracture line, and the availability of a functional orthopaedic table. Three techniques to insert the nail in the proximal and distal fracture fragment with reduction of the fracture site are described. Insertion of distal screws is possible by using ancillary devices. Outcomes are comparable to those of the series using c-arm guidance. In low-income countries, it can been proposed as an alternative to the gold standard in resources constraints settings. In high-income setting this technique can help to reduce exposure of X-ray. CONCLUSION: There is a need to improve equipment in low-income countries hospitals to make trauma surgery with c-arm a gold standard with a minimal exposure to radiation.

Reduction of Neglected Displaced Fractures of the Distal Femoral Physis.

BACKGROUND: We performed open osteoclasis, soft-tissue release, and fracture fragment reduction and fixation to treat 10 cases of neglected physeal fractures of the distal aspect of the femur with severe deformity. To our knowledge, no specific surgical procedure for this problem has been reported in the literature. DESCRIPTION: The procedure is typically performed through an extensile anterolateral approach. With use of an osteotome, the typically abundant fracture callus is disrupted and partially removed to recreate the original fracture line. Through periosteal dissection, an extensive musculoperiosteal detachment and release is achieved to facilitate fracture reduction while protecting the physis from further injury. ALTERNATIVES: Knee rehabilitation in closed, nondisplaced or minimally displaced fractures1.Open callus osteoclasis in combination with a Z-shaped quadriceps tenoplasty, reduction, and plaster cast immobilization2.Open subperiosteal osteoclasis, reduction, and tibial traction3.Open callus osteoclasis, reduction, and condylar plating4.Sequestrectomy with preservation of a periosteal sleeve to treat osteomyelitis complicating an open fracture1.Transfemoral amputation to treat gas gangrene or vascular injury following severe open injury1,5-7. RATIONALE: This procedure was developed in remote medical facilities where patients are often first seen >21 days after the original injury. By that time, closed reduction or standard open reduction and internal fixation techniques are no longer possible. After 6 months of fracture age, the procedure is inefficient. EXPECTED OUTCOMES: This procedure allows correction of limb malalignment and shortening while preserving the growth plate1. IMPORTANT TIPS: In some cases, hypertrophic fracture callus might be mistaken for the femoral diaphysis.An extensive musculoperiosteal release will facilitate reduction of the fracture fragments.The adequacy of reduction must be assessed in all 3 planes intraoperatively.The adequacy of reduction must be assessed in all 3 planes intraoperatively.The adequacy of reduction must be assessed in all 3 planes intraoperatively.
