Objective: To standardize and to develop a fresh osteochondral allograft protocol of procurement, processing and surgical utilization in Brazil. This study describes the steps recommended to make fresh osteochondral allografts a viable treatment option in a country without previous fresh allograft availability. Design: The process involves regul...

Methods : To analyze the osseointegration, the areas of grafts were extracted after 60 days and submitted to the exams of optical coherence tomography (OCT), cone beam tomography, raman spectroscopy and histomorphometry. Objetives The aim of this study is to evaluate the osseointegration of bone allografts that were processed in four different ways...

The use of peripherally inserted central catheters (PICCs) in hospitalized patients is already well established by studies and guidelines, and PICCs are widely used at our institution. However, few studies have been published examining patients using the device in day hospital systems; specifically, if the device brings about early dehospitalizatio...

Use of vascular devices represents one of the most common procedures used as a complementary measure in the treatment of patients. An indication algorithm was established to serve as a guideline for nurses in choosing the best intravenous device, considering the main variables of drug therapy. A protocol approved by the Institute of Orthopedics and...

The purpose of this study was to histologically analyze allografts from cadaveric semitendinous muscle after cryopreservation at -80 degrees C in comparison to a control group kept at only -4 degrees C to test the hypothesis that the histological characteristics of the tissue are maintained when the tendons are kept at lower temperatures. In a tiss...

INTRODUÇÃO: A utilização de enxerto alógeno é um tema que há décadas desperta interesse dos ortopedistas devido às supostas vantagens que apresenta, como diminuição do tempo cirúrgico, maior tamanho de enxerto, ausência de morbidade do sítio doador. OBJETIVO: O artigo a seguir faz análise retrospectiva da casuística do grupo de joelho do IOT-HC-FMU...

Introduction: The use of allograft is a matter of huge interest for orthopaedic surgeons, due to the supposed advantages with its use, like decreased surgical time, larger grafts and no donator site morbidity. Objectives: The aim of this article was to review our experience with the use of allografts on ligament reconstruction. We present the techn...

To compare the bone graft cryopreservation method (at -80 degrees C) with a preservation method using a 98% glycerol solution at room temperature (10 degrees C-35 degrees C), by testing the antibacterial and fungal effects of 98% glycerol and comparatively analyzing the observed histological changes resulting from the use of both methods. This stud...

The authors describe the steps required for the reorganization of the tissue bank of the Orthopedics and Trauma Institute at the Clinics Hospital of the Medical School of the University of Sao Paulo, Brazil, where they work. They mention law 9434 of February 4, 1997, as a guideline for the entire change process and for the preparation of donation a...
