Impacted valgus fractures of the proximal humerus

Abstract
in English, Portuguese

Impacted valgus fractures of the proximal humerus are considered to be a special type fracture, since impaction of the humeral head on the metaphysis with maintenance of the posteromedial periosteum improves the prognosis regarding occurrences of avascular necrosis. This characteristic can also facilitate the reduction maneuver and increase the consolidation rate of these fractures, even in more complex cases. The studies included were obtained by searching the Bireme, Medline, PubMed, Cochrane Library and Google Scholar databases for those published between 1991 and 2013. The objective of this study was to identify the most common definitions, classifications and treatment methods used for these fractures in the orthopedic medical literature.

A fratura impactada em valgo do úmero proximal é considerada um tipo especial de fratura, pois a impactação metafisária da cabeça umeral, com manutenção do periósteo póstero-medial, melhora seu prognóstico quanto à ocorrência de necrose avascular. Essa característica pode, ainda, facilitar a manobra de redução e aumentar o índice de consolidação dessas fraturas, mesmo nos casos mais complexos. Os estudos incluídos foram pesquisados nas bases de dados Bireme, Medline, PubMed, Cochrane Library e Google Scholar publicados de 1991 a 2013. O objetivo deste estudo foi identificar a definição, classificação e os métodos de tratamento dessas fraturas mais usados na literatura médica ortopédica.
