Objectives: To estimate the indirect economic impact of tibial fractures and their associated adverse events (AEs) in Tanzania.

Design: A secondary analysis of the pilot Gentamicin Open (pGO)-Tibia randomized control trial estimating the indirect economic impact of suffering an AE, defined as a fracture-related infection (FRI) and/or nonunion, after an open tibial fracture in Tanzania.

Setting: The pGO-Tibia trial was conducted from November 2019 to August 2021 at the Muhimbili Orthopaedic Institute in Dar es Salaam, Tanzania.

Diagnostic Performance of a telephone questionnaire for fracture-related infections (FRIs) in open tibia fracture patients in Tanzania.

Introduction: Fracture-related infections (FRIs) are a major cause of trauma-associated morbidity worldwide. In 2018, an expert group supported by the AO Foundation, European Bone and Joint Infection Society developed a consensus definition of FRI. Still, there is limited knowledge on the applicability of this definition in low- and middle-income countries (LMICs).

Best Practices for Developing International Academic Partnerships in Orthopaedics.

Traumatic and nontraumatic orthopaedic conditions are major contributors to global morbidity and account for the majority of life-years lived with disability worldwide. Additionally, the burden of musculoskeletal injuries has increased substantially over the past 3 decades. Unfortunately, in low and middle-income countries (LMICs), access to orthopaedic care is limited, leading to a disproportionate burden of disease.

A pilot, masked, randomized controlled trial to evaluate local gentamicin versus saline in open tibial fractures (pGO-Tibia).

Background: Open tibial fractures have a high risk of infection that can lead to severe morbidity. Antibiotics administered locally at the site of the open wound are a potentially effective preventive measure, but there are limited data evaluating aminoglycoside antibiotics. The objective of this study was to assess the feasibility of a clinical trial to test the efficacy of local gentamicin in reducing the risk of fracture-related infection after open tibial fracture.

Determining Critical Topics for Undergraduate Surgical Education in Rwanda: Results of a Modified Delphi Process and a Consensus Conference.

Background Developing a contextually appropriate curriculum is critical to train physicians who can address surgical challenges in sub-Saharan Africa. An innovative modified Delphi process was used to identify contextually optimized curricular content to meet sub-Saharan Africa and Rwanda's surgical needs. Methods Participants were surgeons from East, Central, Southern, and West Africa and general practitioners with surgical experience.

GO-Tibia: a masked, randomized control trial evaluating gentamicin versus saline in open tibia fractures.

Background: The rate of open tibia fractures is rapidly increasing across the globe due to a recent rise in road traffic accidents, predominantly in low- and low-middle-income countries. These injuries are orthopedic emergencies associated with infection rates as high as 40% despite the use of systemic antibiotics and surgical debridement. The use of local antibiotics has shown some promise in reducing the burden of infection in these injuries due to increasing local tissue availability; however, no trial has yet been appropriately powered to evaluate for definitive evidence and the majority of current studies have taken place in a high-resource countries where resources and the bio-burden may be different.

Transfemoral amputation and prosthesis provision in Tanzania: Patient and provider perspectives.

Background: The burden of disability because of traumatic limb amputation, particularly transfemoral amputation (TFA) is disproportionately carried by low- and middle-income countries. The need for improved access to prosthesis services in these settings is well-documented, but perspectives on the burden imposed by TFA and the challenges associated with subsequent prosthesis provision vary among patients, caregivers and healthcare providers.

Objectives: To examine the burden of TFA and barriers to prosthesis provision as perceived by patient, caregiver and healthcare professional, at a single tertiary referral hospital in Tanzania.

Outcomes of Intramedullary Nailing and External Fixation of Open Tibial Fractures: Three to Five-Year Follow-up of a Randomized Clinical Trial.

Background: While surgeons in low and middle-income countries have increasing experience with intramedullary nailing (IMN), external fixation (EF) continues to be commonly used for the management of open tibial fractures. We examined outcomes with extended follow-up of the participants enrolled in a clinical trial comparing these treatments.

Methods: Adults who were ≥18 years old with acute AO/OTA type-42 open tibial shaft fractures were randomly assigned to statically locked, hand-reamed IMN or uniplanar EF.

Establishing Sustainable Arthroscopy Capacity in Low- and Middle-Income Countries (LMICs) through High-Income Country/LMIC Partnerships: A Qualitative Analysis.

Unlabelled: Disparities exist in treatment modalities, including arthroscopic surgery, for orthopaedic injuries between high-income countries (HICs) and low- and middle-income countries (LMICs). Arthroscopy training is a self-identified goal of LMIC surgeons to meet the burden of musculoskeletal injury. The aim of this study was to determine the necessary "key ingredients" for establishing arthroscopy centers in LMICs in order to build capacity and expand training in arthroscopy in lower-resource settings.

Host Perspectives of High-Income Country Orthopaedic Resident Rotations in Low and Middle-Income Countries.

Background: International orthopaedic resident rotations in low and middle-income countries (LMICs) are gaining popularity among high-income country (HIC) residency programs. While evidence demonstrates a benefit for the visiting residents, few studies have evaluated the impact of such rotations on the orthopaedic surgeons and trainees in LMICs. The purpose of this study was to further explore themes identified in a previous survey study regarding the local impact of visiting HIC resident rotations.

Reliability of Modified Radiographic Union Score for Tibia Scores in the Evaluation of Femoral Shaft Fractures in a Low-resource Setting.

Introduction: The modified Radiographic Union Score for Tibia (RUST) fractures was developed to better describe fracture healing, but its utility in resource-limited settings is poorly understood. This study aimed to determine the validity of mRUST scores in evaluating fracture healing in diaphyseal femur fractures treated operatively at a single tertiary referral hospital in Tanzania.

Methods: Radiographs of 297 fractures were evaluated using the mRUST score and compared with outcomes including revision surgery and EuroQol five dimensions questionnaire (EQ-5D) and visual analog scale (VAS) quality-of-life measures.

Cost-effectiveness analysis of prosthesis provision for patients with transfemoral amputation in Tanzania.

Background: Limb loss leads to significant disability. Prostheses may mitigate this disability but are not readily accessible in low- and middle-income countries (LMICs). Cost-effectiveness data related to prosthesis provision in resource-constrained environments such as Tanzania is greatly limited.

Intramedullary nailing versus external fixation for open tibia fractures in Tanzania: a cost analysis.

Objectives: Open tibia fractures pose a clinical and economic burden that is disproportionately borne by low-income countries. A randomized trial conducted by our group showed no difference in infection and nonunion comparing 2 treatments: external fixation (EF) and intramedullary nailing (IMN). Secondary outcomes favored IMN.

Objectives: To determine the international reliability and validity of the modified Radiographic Union Scale for Tibial fracture (mRUST) scoring method for open tibial shaft fractures based on ratings of radiographs by separate groups of North American and Tanzanian surgeons.

Methods: Seven North American and 9 Tanzanian surgeons viewed 100 pairs of AP and lateral radiographs of open tibial shaft fractures obtained in Dar Es Salaam, Tanzania. The radiographs showed 25 patients' fractures at 4 time points postfracture after treatment with either external fixation or intramedullary nailing.

A study protocol for a Pilot Masked, Randomized Controlled Trial Evaluating Locally-applied Gentamicin versus Saline in Open Tibia Fractures (pGO-Tibia) in Dar es Salaam, Tanzania.

Background: Open tibia fractures are a major source of disability in low- and middle-income countries (LMICs) due to the high incidence of complications, particularly infection and chronic osteomyelitis. One proposed adjunctive measure to reduce infection is prophylactic local antibiotic delivery, which can achieve much higher concentrations at the surgical site than can safely be achieved with systemic administration. Animal studies and retrospective clinical studies support the use of gentamicin for this purpose, but no high-quality clinical trials have been conducted to date in high- or low-income settings.

Monoplanar external fixation of comminuted open tibial shaft fractures predicts loss of alignment by one year compared to a statically locked intramedullary SIGN nail.

Aims: This investigation develops a predictive model for loss of alignment (LOA) following fixation of open tibia fractures.

Patients/methods: An analysis was performed of adults with diaphyseal open tibia fractures randomized to intramedullary nailing (IMN) or external fixation (EF) followed at 6, 12, 24, and 52 weeks postoperatively. Demographic data were collected at baseline.

Resident Rotations in Low- and Middle-Income Countries: Motivations, Impact, and Host Perspectives.

Unlabelled: Interest in clinical rotations in low- and middle-income countries (LMICs) has grown among high-income country (HIC) orthopaedic residents. This study addresses the following questions: (1) What motivates HIC surgical residents to rotate in LMICs? (2) What is the impact of rotations on HIC residents? (3) What are the LMIC partner perceptions of HIC collaboration?

Materials And Methods: A search strategy of multiple databases returned 3,740 unique articles pertaining to HIC surgical resident motivations for participating in rotations in LMICs or the LMIC host perspective. Data extraction was dually performed using meta-ethnography, the qualitative equivalent of meta-analysis.

Delays to Surgery and Coronal Malalignment Are Associated with Reoperation after Open Tibia Fractures in Tanzania.

Background: Treatment of diaphyseal open tibia fractures often results in reoperation and impaired quality of life. Few studies, particularly in resource-limited settings, have described factors associated with outcomes after these fractures.

Questions/purposes: (1) Which patient demographic, perioperative, and treatment characteristics are associated with an increased risk of reoperation after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania? (2) Which patient demographic, perioperative, and treatment characteristics are associated with worse 1-year quality of life after treatment of open tibia fractures with intramedullary nailing or an external fixation device in Tanzania?

Methods: A prospective study was completed in parallel to a similarly conducted RCT at a tertiary referral center in Tanzania that enrolled adult patients with diaphyseal open tibia fractures from December 2015 to March 2017.

Travel barriers, unemployment, and external fixation predict loss to follow-up after surgical management of lower extremity fractures in Dar es Salaam, Tanzania.

Objective: Predict loss to follow-up in prospective clinical investigations of lower extremity fracture surgery.

Design: Secondary analysis of 2 prospective clinical trials.

Setting: National public orthopaedic and neurologic trauma tertiary referral hospital in Dar es Salaam, Tanzania, a low-income country in sub-Saharan Africa.

Intramedullary Nailing Versus External Fixation in the Treatment of Open Tibial Fractures in Tanzania: Results of a Randomized Clinical Trial.

Background: Open tibial fractures are common injuries in low and middle-income countries, but there is no consensus regarding treatment with intramedullary nailing versus external fixation. The purpose of the present study was to compare the outcomes of initial treatment with intramedullary nailing or external fixation in adults with open tibial fractures.

Methods: We conducted a randomized clinical trial (RCT) at a tertiary orthopaedic center in Tanzania.

Surgical Implant Generation Network (SIGN) Fin nail versus SIGN standard intramedullary nail for distal diaphyseal femur fractures treated via retrograde approach.

Introduction: Surgical fixation of distal diaphyseal femur fractures remains a major challenge in developing countries given limited availability of fluoroscopy. The Surgical Implant Generation Network (SIGN) Standard Intramedullary Nail and SIGN Fin Nail are two modalities developed to address this challenge; the Fin Nail additionally avoids needing to place proximal interlocking screws. While efficacy of the Standard Nail has been established, outcomes following fixation with the Fin Nail are unknown.

Early treatment of open diaphyseal tibia fracture with intramedullary nail versus external fixator in Tanzania: Cost effectiveness analysis using preliminary data from Muhimbili Orthopaedic Institute.

Introduction: Open tibia fractures are some of the most common types of Orthopedics injuries in low- and middle-income countries (LMICs). In Tanzania, open tibia fractures are treated either conservatively by prolonged cast or surgically by external fixation (EF) or intramedullary nail (IMN) when available. The cost of treatment and amount of time patients spend away from work are major economic concerns with prolonged casting and EF.
