Accelerated rehabilitation versus conventional rehabilitation in total hip arthroplasty (ARTHA): a randomized double blinded clinical trial.

Objectives: compare an accelerated physiotherapeutic protocol to a conventional physiotherapeutic protocol in total hip arthroplasty patients.

Methods: a randomized double blinded clinical trial performed from August 2013 to November 2014. Forty-eight patients diagnosed with hip osteoarthritis submitted to a total hip arthroplasty surgery.

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.

Update on open reduction and internal fixation of unstable pelvic fractures during pregnancy: case reports.

Unlabelled: This article aims to report four cases of unstable pelvic fractures in pregnant women treated by open reduction and internal fixation.

Cases Report: The study included four cases of pregnant women with unstable pelvic fractures; their outcomes were analyzed and discussed. Data were obtained from two University Hospitals.

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.

Rehabilitation following total hip arthroplasty evaluation over short follow-up time: randomized clinical trial.

Unlabelled: Hip osteoarthritis (OA) is a degenerative disease, and total hip arthroplasty (THA) is one of the surgical procedures of choice to improve the OA patient's quality of life. Without a rehabilitation program, THA patients will develop functional limitations. A randomized double-blind trial was performed between July 2009 and October 2011 to compare in a short follow-up time two groups of patients who underwent THA for OA.

TOTAL HIP ARTHROPLASTY WITH BIOMEC PROSTHESIS: 20-YEAR FOLLOW-UP.

Objective: To analyze the clinical and radiological outcomes from total hip arthroplasty using the Biomec prosthesis over a 20-year period (1988 to 2009).

Methods: The patients were evaluated clinically in accordance with the Merle d'Aubigné and Postel functional classification, and underwent anteroposterior (AP) radiography of the pelvis and the operated joint in lateral view. The variables evaluated were acetabular and femoral osteolysis, polyethylene wear, nail migration, follow-up and clinical outcomes.

Mid-term follow-up of acetabular reconstruction using bovine freeze-dried bone graft and reinforcement device.

Objective: To report clinical and radiographic graft incorporation capability of bovine freeze-dried bone grafts.

Methods: Twenty five patients were enrolled. The mean follow-up was eight years.

Femoral and acetabular revision using impacted nondemineralized freeze-dried bone allografts.

Background: Favorable results have been obtained by the use of deep-frozen bone allografts in total hip arthroplasty. However, owing to the shortage of deep-frozen allografts and the risk of infectious disease, other materials have been studied, such as sterile nondemineralized freeze-dried allografts. The aim of this study was to describe midterm clinical outcomes and radiographic bone incorporation of human freeze-dried bone grafts in 42 revision total hip arthroplasty procedures using cancellous impacted bone grafting.
