Poor results of drilling in early stages of juxta-articular osteonecrosis in 12 joints affected by Gaucher disease

Background and purpose Gaucher disease is heterogeneous. One of the most devastating complications is bone involvement, ranging from mild osteopenia to osteonecrosis, but no markers have been discovered to predict onset and/or progression. We describe our experience in a large referral center using drilling for juxta-articular osteonecrosis in young patients with Gaucher disease

Physical and sports activity after hip arthroplasty

A artroplastia é utilizada para reconstrução da articulação do quadril, visando minimizar a dor e possibilitar o retorno às atividades de vida diária, esportivas e de lazer. O objetivo deste artigo é analisar na literatura as indicações e contraindicações referentes à prática de atividade física, esportiva e lazer após a artroplastia de quadril. Essa revisão aborda estudos publicados entre os anos de 1980 e 2009, obtidos por buscas em bancos de dados eletrônicos Medline, Scielo, Ovid, Infomaworld, Sciencedirect, Springerlink, Interscience, Sportdiscuss, Bireme, Informglobal, Opas, Ovid, Diseasedex, Eric, que totalizaram 39 artigos. Os artigos analisados apontam para a utilização de atividade física, esportiva e de lazer de baixo impacto. como a caminhada, natação, boliche, ciclismo, dentre outras. Outra indicação constatada na literatura é a utilização da atividade física e esportiva visando à manutenção do condicionamento físico, qualidade óssea e controle do peso corporal. Há ressalvas na literatura sobre a utilização de atividades de alto impacto, esporte com giro como o basquete e futebol ou com grande intensidade como tênis e a corrida, bem como os esportes de luta. As atividades físicas, esportivas e de lazer mais indicadas após uma atroplastia de quadril são as de baixo impacto como a hidroginástica, natação, caminhada, dentre outras. O início dessas atividades deve aguardar a liberação do médico, mas em média iniciam 60 dias após a cirurgia.Hip arthroplasty is used for reconstruction of the hip joint to reduce pain and to make the return to daily life, physical, sports and leisure activities possible. The objective of this article was to analyze in the literature the indications and counter-indications referring to practice of physical, sportive and leisure activities after hip arthroplasty. This revision approaches studies published between 1980 and 2009, obtained in searches in the Medline, Scielo, Ovid, Infomaworld, Sciencedirect, Springerlink, Interscience, Sportdiscuss, Bireme, Informglobal, Opas, Ovid, Diseasedex and Erics electronic databases with a total of 39 articles. The analyzed articles point to the use of physical, leisure and sports of low impact activities such as walking, swimming, bowling, cycling and others. Another indication evidenced in the literature is the use of physical and sportive activity aiming at the maintenance of physical fitness, bone quality and body weight control. The literature shows concerns with the use of activities of high impact or with great intensity like tennis and jogging, as well as fights

Long-term results of 32-mm alumina-on-alumina THA for avascular necrosis of the femoral head

BACKGROUND: Ceramic bearings in total hip arthroplasty (THA) have been introduced in clinical practice to minimize the problem of polyethylene particle-induced osteolysis. The aim of the study is to report the results of 68 consecutive alumina-on-alumina THAs done in 61 patients for avascular necrosis (AVN) of the femoral head. MATERIALS AND METHODS: In all implants a press-fit cup was used; it was combined with a 32-mm alumina head and with titanium-alloy stems. The mean age at surgery was 50 years. At an average follow-up of 13 years two hips have been revised, one for periprosthetic infection and one for excessive abduction of the cup. RESULTS: No revision for aseptic loosening is recorded; one anatomical cementless femoral stem had radiological evidence of definite aseptic loosening. No dislocations occurred, and no osteolysis was observed. CONCLUSIONS: The results support the application of alumina-alumina THA for long-lasting replacements
