The causes of 100 disc herniation reoperations are analyzed and discussed in a review: we find a recurrence of disc herniation at the same level in 62% of the reoperated cases, a pseudorecurrence in 24% and a closely connected nerve route in 14%. We reoperated on 44% within the first two years and on 69% within the first five years. The interval between the operations is longer, when there is a short painfree interval following surgery and also a long history of pre-operative symptoms. The variables of risk of prolapse recurrence are recorded as a risk score. Retrospectively, 64% belonged to a risk group according to this score. The correlation between operation intervals and scores show, that patients with a short interval have high scores.
Os grandes avanços da gerontología nos últimos anos não encontraram na neurocirurgia um éco tão grande quanto nas outras especialidades médicas. Em geral as contribuições encontradas na literatura médica se restringem aos aspectos diagnósticos e terapêuticos especiais dos tumores e insufici ências vasculares cerebrais nessa faixa etária ( Para evitar repetição no texto, usaremos as seguintes siglas para designar os diferentes grupos de casos: TCFL -traumatismos cranianos fechados leves; TCFG = traumatismos cranianos fechados graves; TCA = traumatismos cranianos abertos; HI •= hematomas intracranianos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
