Isolated open tibial shaft fracture: a seven-hospital, prospective observational study in two Latin America countries.

Introduction: open tibial fractures are challenging due to the frequent severe bone injury associated with poor soft tissue conditions. This is relevant in low- and middle-income countries, mainly related to delayed definitive fixation and lack of adequate training in soft tissue coverage procedures. Due to these factors, open tibial fracture is an important source of disability for Latin American countries.

THE MISSING LINK IN THE HISTORY OF THE LOCKED INTRAMEDULLARY NAIL.

Femoral Shaft intramedullary nails were first described by the Aztecs in 16th century, but the modern use of intramedullary nails as the gold standard treatment for femoral shaft fractures began with Gerald Kuntcher in 1939. From the first Kuntcher's study in 1939, to the creation of interlocking nail, a long and some minor developments were described around the world. However, a major development is missing: the first nail to have a rotational and vertical stability locking system was described by Flavio Godoy Moreira, but was never published on an indexed journal for the correct historical reference.

Orthopaedic trauma care during the COVID-19 Pandemic: the Latin American perspective.

At first glance, the COVID-19 pandemic and the field of orthopaedics and traumatology do not appear to be related. Although orthopaedists are not considered front-line personnel in the fight against the pandemic, the role of the surgeon as part of the overall health care team is crucial. The specialty of orthopaedics and orthopaedic trauma, due to its extraordinary scope, affects individuals of all ages and timely care affects patients' long-term function and quality of life.

Outpatient parenteral antimicrobial therapy for orthopedic infections - a successful public healthcare experience in Brazil.

Treatment of orthopedic infections usually requires prolonged antimicrobial therapy, ranging from 14 days up to 6 months. Nowadays, rising levels of antimicrobial resistance demands parenteral therapy for many patients. Outpatient parenteral antimicrobial therapy (OPAT) is a modality that allows treatment out of hospital in these situations.
