Perceived Risk of Elective Total Hip Arthroplasty: A Brazilian Hip Society Survey.

Background: As total hip arthroplasty (THA) has become more common and widely available, candidates now often present with multiple risk factors that increase the risk of complications, directly impacting the cost of surgery and provider compensation. The present study was designed to better understand the impact of these factors and the perceptions of hip surgeons in Brazil.

Methods: All 880 full members of the Brazilian Hip Society (SBQ) were invited to complete an online questionnaire on preoperative risk factors, adapted from the previous American Association of Hip and Knee Surgeons survey.

Strategy to avoid vascular injuries in revision total hip arthroplasty with intrapelvic implants.

Aims: Our objective was describing an algorithm to identify and prevent vascular injury in patients with intrapelvic components.

Methods: Patients were defined as at risk to vascular injuries when components or cement migrated 5 mm or more beyond the ilioischial line in any of the pelvic incidences (anteroposterior and Judet view). In those patients, a serial investigation was initiated by a CT angiography, followed by a vascular surgeon evaluation.

Results of Medium-Term Survival of the Non-Cemented Logical Femoral Stem.

 The main objective of the present study was to evaluate the clinical and radiographic results of the Logical (Baumer, Mogi Mirim, SP, Brasil) cementless femoral stem in primary total hip arthroplasties (THAs).  A retrospective cohort study of 632 patients submitted to primary THA with the Logical cementless femoral stem. The study period was between January 2004 and January 2015.

Is there a relationship between the neutrophil/lymphocyte ratio and bilaterality in patients with coxarthrosis?

Objective: The objective of this study was to evaluate the relationship between the neutrophil/lymphocyte ratio and the presence of signs of arthrosis in both hips in patients followed at this medical center.

Methods: This was a cross-sectional, retrospective study through the analysis of medical records and database review of patients over 18 years of age with hip arthrosis, followed at the outpatient clinic of this hospital.

Results: Regarding the analysis of the Mann-Whitney test to correlate the neutrophil/lymphocyte ratio and laterality, a bi-lateral test result of  = 0.

Total hip arthroplasty: a still evolving technique.

It has been advocated that total hip arthroplasty (THA) is probably the most successful surgical intervention performed in Medicine. In the 1960s, Sir John Charnley not only introduced, but also modified and improved the technique of cemented arthroplasties. The concepts on biological fixation established by Pillar and Galante served as the foundation for the development of uncemented implants that are now used worldwide.

Acetabular revision in total hip arthroplasty with tantalum augmentation and lyophilized bovine xenograft.

Objective: To evaluate a mixed technique of acetabular reconstruction, which uses trabecular metal in the form of tantalum augments associated with lyophilized bovine xenograft.

Methods: Fifteen patients were evaluated prospectively, who underwent acetabular reconstruction with impacted lyophilized bovine xenograft associated with the use of tantalum augments. The main outcome was the failure of the tantalum-bone interface.

The prevalence of femoroacetabular impingement in radiographs of asymptomatic subjects: a cross-sectional study.

Background: There is a lack of uniformity in the diagnostic criteria for femoroacetabular impingement (FAI), and few studies discuss the prevalence of radiographic changes in asymptomatic individuals. These factors make it difficult to establish a natural history of this disease. The aim of this study was to assess the prevalence of radiographic signs of CAM and Pincer FAI in an asymptomatic population.

Lyophilized xenograft: a case series of histological analysis of biopsies.

The reconstruction of an acetabular bone defect is one of the most important aspects of revision total hip arthroplasty surgery. It can be done by the use of grafts. Therefore, many kinds of grafts may be used and lyophilized xenograft is an alternative example.

Prevalence of radiographic markers of femoroacetabular impingement in asymptomatic adults.

Objective: to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI) in asymptomatic adults and correlate them with data from physical examinations.

Methods: We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, anteroposterior (AP) pelvis radiographs with three incidences, Dunn 45° and Lequesne false profile of each hip, to measure the variables.

The role of antibiotic prophylaxis with sodium ceftriaxone to prevent bacterial translocation associated with hypovolemic shock: an experimental study in rats.

One of the measures adopted to reduce or prevent intestinal bacterial translocation (BT) in patients who are in hemorrhagic shock consists of prophylactic antibiotics. This study attempted to assess the effectiveness of administering systemic antibiotic to suppress BT in rats submitted to hemorrhagic shock. Sixty-eight male Wistar rats were divided into two experiments.
