1. REUSE OF COLLAGEN AND HYDROXYAPATITE FROM THE WASTE PROCESSING OF FISH TO PRODUCE POLYETHYLENE COMPOSITES
In recent years, the increase in the generation of waste (e.g., bones and skin) from the processing of fish-based food related to the increase in fish consumption and the accumulation of synthetic polymers in the environment are causing major environmental concerns. Hydroxyapatite (HA) extracted from the bones and collagen from the skin of fish processing re

4. Osseointegration aspects of placed implant in bone reconstruction with newly developed block-type interconnected porous calcium hydroxyapatite
ABSTRACT Artificial bone has been employed to reconstruct bone defects. However, only few reports on implant placement after block bone grafting exist. Objectives The purpose of this study was to evaluate the osseointegration of dental implant in bone reconstructions with interconnected porous calcium hydroxyapatite (IP-CHA). Material and Methods The IP-

5. GRAFT OR HOMOLOGOUS IMPLANT IN THE CORRECTION OF FEMORAL SEGMENTAL BONE DEFECT IN DOGS ASSOCIATED TO INOCULATION OF BONE MARROW MONONUCLEAR CELL FRACTION / ENXERTO OU IMPLANTE HOMÓLOGO NA CORREÇÃO DE DEFEITO ÓSSEO SEGMENTAR FEMORAL EM CÃES ASSOCIADO A INOCULAÇÃO DA FRAÇÃO DE CÉLULAS MONONUCLEARES DA MEDULA ÓSSEA
Bone defects due to trauma, postoperative and mutilating surgery complications, associated to removal of neoplasia, are part of the routine of hospitals and veterinary clinics. Bone grafts, within all their variants, represent the main viable alternative in the structural correction of great bone losses. Currently, the search for alternatives to correct thes

6. Tratamento da pseudoartrose do escafoide : estudo comparativo entre o uso do exerto ósseo da extremidade distal do rádio vascularizado e não vascularizado / Treatment of scaphoid nonunion : comparative study of the use of vascularized and nonvascularized bone graft from the dorsal distal tip of the radius
Avaliaram-se os aspectos clínicos, funcionais e radiográficos de 86 pacientes portadores de pseudoartroses do escafoide. Comparam-se 46 pacientes submetidos à técnica de enxerto ósseo vascularizado dorsal do rádio distal, baseado na artéria suprarretinacular intercompartimental 1,2* (Grupo I), e 40 pacientes submetidos à cirurgia pela técnica de enx

7. Bancos de tecidos musculoesqueléticos no Brasil : análise à luz da bioética e da biossegurança
Introduction: In this research we present an analysis of the bone tissue banks, that were authorized to work for the National System of Transplants, in which it concerns the technicians of attainment, processing, storage and use of homologous graft (allograft), relating the data collected with the biosafety criteria. We analyze these data in light of the bio

8. Análise da integração do aloenxerto ósseo de crânio criopreservado e irradiado, adicionado de medula óssea autógena: estudo experimental em coelhos / Deep frozen, irradiated calvarial bone allograft added with autogenous bone marrow incorporation analysis. Experimental study in rabbits
Searching for alternatives to autogenous bone graft in craniofacial reconstructions, it is proposed deep-frozen, irradiated calvarial bone allograft added with autogenous bone marrow utilization. Twenty and one rabbits were sacrificed and their parietal bones harvest, deep-frozen and gamma irradiated with 50kGy. The allografts were implanted in twenty one ot

9. ASPECTOS BIOMECÂNICOS, BACTERIOLÓGICOS E MICOLÓGICOS DE DIÁFISES FEMORAIS CANINAS CONSERVADAS EM GLICERINA A 98% OU MEL / BIOMECHANICAL, BACTERIOLOGICAL AND MYCOLOGICAL ASPECTS OF CANINE FEMORAL SHAFTS CONSERVED IN 98% GLYCERIN OR HONEY:
The most important function of bone cortical allograft is basically of mechanical sustentantion. The stability and resistance have an important signification in the success of bone grafting. The aim of this study was to compare the axial compressive resistance of canine femoral shafts conserved in 98% glycerin or honey, kept for 30 days. Three groups had bee

10. Influence of different particle sizes of anorganic bovine bone matrix on bone repair process. Histologic and radiographic analysis of surgically created defects in rabbit calvaria / Influencia dos diferentes tamanhos de particulas da matriz ossea bovina anorganica no processo de reparo osseo ; : Analise histologica e radiografica de defeitos criados cirurgicamente em calvaria de coelhos
The aim of this present study was to analyze, clinical and histologically, the influence of anorganic bovine bone matrix (ABBM) particle size on bone repair. Four calvarial defects of 8 millimeters each were prepared in 18 adult New Zealand rabbits, two in the right side, and two in the left side. The defects were filled with either particulate autogenous bo

12. Telescope Allograft Method to Reconstitute the Diaphysis in Limb Salvage Surgery
We propose a surgical technique for structural allograft reconstitution of the diaphysis of long bones, maximizing surface contact between host and allograft bone. This method, analogous to a telescope, overlaps the graft and host bone, theoretically increasing bone surface contact substantially. We report the outcome of 22 telescoped allograft junction site
