Standard or Fin SIGN® nail? which option is better for the treatment of femoral fractures in low and middle-income countries?

PURPOSE: Femoral fractures are common in low and middle-income countries (LMIC), predominantly caused by high-energy trauma. The surgical implant generation network (SIGN®) program offers two different intramedullary nails in LMIC which are designed to be used without image intensifier free of charge for the patients: the SIGN standard nail (SSN®) and the SIGN Fin nail (SFN®). This study aimed to compare the results of the SSN® and the SFN® for the treatment of middle and distal shaft femoral fractures through a retrograde approach. MATERIAL AND METHODS: This was a retrospective, descriptive, and non-experimental study including all consecutive patients who underwent surgical management of middle or distal shaft femoral fracture between January 2017 and May 2022 in an NGO hospital located in Freetown, Sierra Leone. The duration of surgery, type of reduction, complications like screw loosening, implant migration, anterior knee pain and non-union rate at six months of follow up were evaluated. RESULTS: A total of 122 patients were included in the study. Group A: 60 patients were managed with SSN® and Group B: 62 patients with SFN®. The mean operative time was 104 min with SSN® and 78 with SFN® (p < 0.001). Open reduction of the fracture was necessary in ten (16.7%) patients with SSN® and 12 (19.4%) patients treated with SFN® (p = 0.69). Non-union was observed in one (1.7%) patient with SSN® and two (3.2%) patients with SFN® (p = 0.57). CONCLUSIONS: Both options seem equally effective in treating midshaft and distal femoral shaft fractures. The SFN® reduces the surgical time, due to this fact, in polytraumatized patients, patients with bilateral femur fracture or patients with ipsilateral tibia fracture, it can be considered as the best option to be used. There was no statistical difference in the complications presented by the two groups.

Enhancing Cranio-Maxillofacial Fracture Care in Low- and Middle-Income Countries: A Systematic Review.

Background: Cranio-maxillofacial (CMF) injuries represent a significant challenge in low- and middle-income countries (LMICs), exacerbated by inadequate infrastructure, resources, and training. This systematic review aims to evaluate the current strategies and solutions proposed in the literature to improve CMF fracture care in LMICs, focusing on education, patient transfer, and off-label solutions. Methods: A comprehensive literature search was conducted using PubMed/Medline from January 2000 to June 2023. Studies were selected based on the Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA). Solutions were categorized into three main areas: education (digital and on-site teaching, fellowships abroad), patient transfer to specialized clinics, and off-label/non-operative solutions. Results: Twenty-three articles were included in the review, revealing a consensus on the necessity for enhanced education and training for local surgeons as the cornerstone for sustainable improvements in CMF care in LMICs. Digital platforms and on-site teaching were identified as key methods for delivering educational content. Furthermore, patient transfer to specialized national clinics and innovative off-label techniques were discussed as immediate solutions to provide quality care despite resource constraints. Conclusions: Effective CMF fracture care in LMICs requires a multifaceted approach, prioritizing the education and training of local healthcare professionals, facilitated patient transfer to specialized centers, and the adoption of off-label solutions to leverage available resources. Collaborative efforts between international organizations, local healthcare providers, and educational institutions are essential to implement these solutions effectively and improve patient outcomes in LMICs.

Off-Label Use of an External Hand Fixator for Craniomaxillofacial Fractures-An Anatomical Feasibility Study.

BACKGROUND: The lack of resources limits the treatment of craniomaxillofacial fractures (CMF) in low-income countries (LIC). Therefore, Barton bandages and/or interdental wiring are considered in these regions. Fracture reduction is maintained by permanent occlusion for 6 weeks, which often leads to limited compliance and dissatisfying results. The aim of this cadaver-based study is to evaluate the feasibility of the use of an external face fixator (EFF) for the treatment of CMF, its biomechanical values and to define the optimal pin insertion points and angles. MATERIALS AND METHODS: An AO hand fixator was used. CMF of types Le Fort 1-3 with split fractures of the hard palate were treated with EFF on 13 anatomical specimens. Fractures were created using a chisel, and pins were placed in specific anatomical regions. The maximal pull-out force [N] of pins was analysed by a tensile force gauge, and Fmax of the mandibular pins was evaluated. Computer tomography scans were performed on the healthy, fractured and EFF-treated skulls. RESULTS: The pull-out forces for the single pins were mandibular pins (n = 15, median 488.0 N), supraorbital pins (n = 15, median 455.0 N), zygomatic pins (n = 14, median 269.1 N), medial hard palate pins (n = 12, median 208.4 N) and lateral hard palate pins (n = 8, median 49.6 N). CONCLUSIONS: The results indicate that the operation technique is feasible, and the stability of the EFF is sufficient for maintaining the reduction. The required pins can safely be inserted into the described areas with good reduction results. Using EFF offers a feasible alternative to the non-surgical treatment of CMF in LIC.

Usefulness of external fixation and reverse Sural fasciocutaneous flap: Treatment of grade III B open tibial fractures in resource-limited settings.

PURPOSE: Sierra Leone is a low-income country located on the west coast of Africa where the majority of the population does not have free access to emergency medical and surgical services, the principal cause of open tibia fractures is motorcycle collision. Open fractures of the middle and distal third of the tibial segments, particularly those classified as type III B, represent a challenge for orthopedic surgeons because of the loss of soft tissue coverage. The Reverse Sural Fasciocutaneous Flap (RSFF) has been shown to be an ideal and reproducible option for the treatment of soft tissue defects. The main aim of this study was to demonstrate the experience in Resource Limited Settings (RLS) by means of a short series of the efficacy of using a combination of external fixation and RSFF in the treatment of grade III B open tibia fractures where plastic surgeons were not available. METHODS: This retrospective, descriptive, and non-experimental study included 8 patients who underwent surgical intervention between September 2020 and September 2021. RESULTS: The skin defects were of various sizes; the smallest size was 4 × 7 cm, and the biggest size of 12 × 18 cm. We obtained a success rate in seven of the eight cases. CONCLUSIONS: External fixation and reverse sural fasciocutaneous sural flap are excellent therapeutic options for the treatment of open grade III B diaphyseal and metaphyseal distal tibial fractures.

Off-Label Treatment for Severe Craniomaxillofacial Fractures in Low-Income Countries-A Novel Operation Method with the External Face Fixator.

INTRODUCTION: Craniomaxillofacial fractures (CMF) are common in low-income countries (LIC). Due to limited resources, treatment of these fractures usually consists of interdental wiring or immobilization with a Barton bandage to maintain the reduction by permanent occlusion. These non-surgical treatment methods often lead to unsatisfactory results, such as a disturbed dental occlusion and lockjaw. The aim of this study is to present an off-label treatment option for CMF by applying a hand fixator as external face fixator (EFF) and to demonstrate the surgical method in detail. MATERIALS AND METHODS: The feasibility and postoperative outcomes of this new off-label operation technique were evaluated by analyzing patients with CMF (n = 13) treated at an NGO hospital in Sierra Leone between 2015 and 2019. RESULTS: The application of the EFF was feasible. The biggest advantage compared to the conventional non-operative methods was, that a dynamic occlusion was still possible during the 6 weeks healing period. Hence, patients could eat and drink almost normally and perform dental hygiene with the EFF in place. We did not discover pintrack infections or other complications. Three patients developed an oronasal fistula due to traumatic a palatal bone loss of about 7-8 mm which was treated by a palatal mucoperiosteal flap 15-20 days after the first operation. DISCUSSION AND CONCLUSIONS: In LIC, where plate osteosynthesis for CMF cannot be performed due to limited resources the application of an EFF is a promising alternative for a better outcome and an improved quality of life for the patients.

Economic burden of road traffic injuries in sub-Saharan Africa: a systematic review of existing literature.

OBJECTIVE: This systematic review aims to explore and synthesise existing literature on the direct and indirect costs from road traffic injuries (RTIs) in sub-Saharan Africa (SSA), the quality of existing evidence, methods used to estimate and report these costs, and the factors that drive the costs. METHODOLOGY: MEDLINE, SCOPUS, ProQuest Central, Web of Science, Global Index Medicus, Embase, World Bank Group e-Library, Econlit, Google Scholar and WHO webpages were searched for relevant literature. References of selected papers were also examined for related articles. Screening was done following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were included in this review if they were published by March 2019, written in English, conducted in SSA and reported original findings on the cost of illness or economic burden of RTIs. The results were systematically examined, and the quality assessed by two reviewers using a modified Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS: Eleven studies met the inclusion criteria. RTIs can cost between INT$119 and 178 634 per injury and INT$486 and 12 845 per hospitalisation. Findings show variability in costing methods and inadequacies in the quality of existing evidence. Prolonged hospital stays, surgical sundries and severity of injury were the most common factors associated with cost. CONCLUSION: While available data are limited, evidence shows that the economic burden of RTIs in SSA is high. Poor quality of existing evidence and heterogeneity in costing methods limit the generalisability of costs reported.
