HEMIEPIPHYSIODESIS USING EIGHT-PLATE VERSUS BLOUNT STAPLE TO CORRECT GENU VALGUM AND GENU VARUM

Natasha Vogel Majewski Rodrigues et al. Acta Ortop Bras. 2020 Jul-Aug.

Abstract
in English, Portuguese

Objective: Our objective is to evaluate whether the use of guided growth with eight-plates is more effective than the use of Blount staples for the correction of the idiopathic genu varum or idiopathic genu valgum.

Methods: A systematic review (SR) was carried out according to the appropriate methodology for randomized clinical trials (RCTs). We searched seven databases through a previously defined methodology, and we included RCTs, regardless of language, period of publication and status of publication.

Results: Resulted in 6830 articles retrieved. Of theses, we identified 14 potential eligible studies. but just one RCT was included for the SR. The included RCT compares the eight-plate and the Blount staple and showed no statistically significant difference for the outcomes of time to correct the deformity, postoperative pain after 24 hours and postoperative pain after 72 hours. The study is of low or very low level of evidence to determine the most effective technique. We didn't find a RCT that compared the correction of the genu varum.

Conclusion: Good quality randomized clinical trials comparing Blount staples versus eight-plaque must be performed to determine which technique is superior for coronal plane corrections. Level of Evidence I, Systematic review of Level RCTs.

Objetivo: Avaliar se o uso do crescimento guiado com placas em oito é mais eficaz que os grampos de Blount na correção do geno varo idiopático ou geno valgo idiopático.

Métodos: Foi realizada uma revisão sistemática (RS), de acordo com a metodologia apropriada para busca de ensaios clínicos randomizados (ECR). Pesquisamos em sete bancos de dados por meio de uma metodologia definida anteriormente e incluímos ECR, independentemente do idioma, período ou status da publicação.

Resultados: Foram recuperados 6830 artigos. Destes, 14 estudos possivelmente elegíveis foram encontrados, mas apenas um ECR foi incluído para a RS. O ECR incluído compara placas em oito e grampos de Blount, não mostrando diferença estatisticamente significante para os resultados de tempo na correção da deformidade, dor pós-operatória após 24 horas e dor pós-operatória após 72 horas. O estudo é de nível baixo ou muito baixo de evidência para determinar a técnica mais eficaz. Não encontramos um ECR que comparasse a correção do geno varo.

Conclusão: Ensaios clínicos randomizados de boa qualidade comparando grampos de Blount com oito placas devem ser realizados para determinar qual técnica é superior para correções do plano coronal. Nível de Evidência I, Revisão sistemática de ECRC.
