Prior use of antibiotics and immunosuppression are risk factors for fracture-related infection during the COVID-19 pandemic period: a Brazilian prospective cohort study.

Background: Little is known about the role of COVID-19 pandemic period on the epidemiology of fracture-related infection (FRI). The present study summarizes the changes in the prevalence, microbiology, and risk factors of FRI during this period.

Methods: A prospective single-center cohort study assessed in the setting of COVID-19 pandemic (2020-2021), clinical, microbiological aspects, and independent risk factors (RF) of FRI.

Type of antibiotic but not the duration of prophylaxis correlates with rates of fracture-related infection.

Purpose: The issue of optimal prophylactic antibiotic administration for closed and open fracture surgeries remains controversial. The purpose of this study was to assess the role of type and duration longer than 48 h of antibiotic prophylaxis on the rates of fracture-related infection (FRI).

Methods: This is a single-center, prospective observational cohort study carried out with patients undergoing surgery for implants insertion to fracture stability.

Microbiological diagnosis of intramedullary nailing infection: comparison of bacterial growth between tissue sampling and sonication fluid cultures.

Background: Intramedullary nailing (IMN) has been frequently indicated to treat long bone open and closed fractures, but IMN infection (IMNI) may have devastating consequences. Sonication has been regarded as an important add-on for microbial identification on a variety of orthopaedic implant-associated infections, but its role in the IMNI is poorly studied. We aim at evaluating the accuracy obtained by conventional peri-implant tissue culture (TC) samples with sonication fluid cultures (SCs) of IMNI.

Intramedullary reaming modality for management of postoperative long bone infection: a prospective randomized controlled trial in 44 patients.

Background: Studies addressing the management of intramedullary infection are mainly retrospective and with a limited number of cases. Reaming can be performed using either conventional reaming or using the reamer/irrigator/aspirator (RIA) system. Until now there have been no comparative prospective studies between these two methods.

Treatment of two-part fractures of the surgical neck of the humerus using a locked metaphyseal intramedullary nail proximally with angular stability.

Objectives: To evaluate the functional results from patients with surgical neck fractures treated with a locked metaphyseal intramedullary nail and angular stability.

Methods: Twenty-two patients between the ages of 21 and 69 years were evaluated prospectively between January 2010 and January 2011. Their time taken for consolidation, age, sex, complications and functional results were correlated using the modified protocol of the University of California at Los Angeles (UCLA).

Interlocking screws placed with freehand technique and uni-planar image intensification: the "dip-stick" technique.

Objective: To report our experience with a novel alternative method of freehand interlocking of intramedullary nails. This method requires the use of only anterior-posterior image intensification and an intramedullary guide wire to verify screw placement. Our results are compared with historical results in the literature.
