Methods: we performed a literature review of e as opções de tratamento. Métodos: Realizamos uma revisão da literatura de estudos clínicos relevantes em múltiplas bases de relevant clinical studies in multiple databases, including PubMed, dados, incluindo PubMed, MedLine e Scopus, de janeiro de 1989 MedLine and Scopus, from January 1989 to October 2020. a outubro de 2020. Resultados: Há consenso para o tratamento Results: There is consensus for surgical treatment of intra-articular cirúrgico de fraturas intra-articulares com desvio superior a fractures with a deviation greater than 2 mm, metadiaphyseal 2 mm, fraturas metadiafisárias com má rotação e/ou malangula- fractures with malrotation and/or malangulation, open fractures ção, fraturas expostas e fraturas instáveis.

Conclusion: The use of more rigid implants implantes mais rígidos permite a manutenção do alinhamento durante o processo de consolidação e menor risco de perda da allow alignment maintenance during healing process and lower redução.

Although metatarsal fractures were more common trauma mechanism patterns are twisting of the forefoot, common than phalangeal fractures, this study showed that the axial trauma, and crushing. The forces producing these injuries proportion of phalangeal open fractures was significantly higher are either direct (crush) or indirect (twist and axial). Specifically in than that of metatarsal fractures (33% and 16%, respectively). hallux phalanx fractures, the two mechanisms commonly involved Moreover, approximately 20% of all phalanx fractures were open.1 are axial trauma and crushing.4 In a study conducted in the United Kingdom, the authors observed Hallux fractures
