ABSTRACT
Displaced fractures (> 2 mm) of the lateral malleolus, without medial or syndesmotic injuries, are often the subject of controversy regarding the best treatment option. In the past, these fractures were usually treated conservatively using a cast for 6 to 8 weeks without weightbearing. Currently, most of the patients desire a quick return to their previous activities, what makes surgical treatment a reasonable choice. It has benefits as earlier ankle mobilization and weightbearing. It also restores ankle biomechanics, preventing secondary osteoarthritis. However, postoperative complications with the standard lateral incision exist such as implant discomfort, dehiscence and infection. Minimally invasive techniques have been described to help avoiding these complications. This technical note described a short single-incision approach for the surgical treatment of displaced oblique fibular fractures type AO/OTA 44-B1 with an antiglide plate that presents the advantage of less risk of damaging the soft tissues, periosteal stripping and disturbance of the fracture hematoma.

OBJECTIVES: To describe the surgical treatment of fractures that involves the hallux interphalangeal joint, current indications and management options. METHODS: we performed a literature review of relevant clinical studies in multiple databases, including PubMed, MedLine and Scopus, from January 1989 to October 2020. RESULTS: There is consensus for surgical treatment of intra-articular fractures with a deviation greater than 2 mm, metadiaphyseal fractures with malrotation and/or malangulation, open fractures and unstable fractures. CONCLUSION: The use of more rigid implants allow alignment maintenance during healing process and lower risk of reduction loss. Valgus deformity and interphalangeal joint osteoarthritis are possible complications that must be avoided. Level of Evidence III, Systematic review of Level III studies.
OBJETIVOS: destacar o tratamento cirúrgico das fraturas que envolvem a articulação interfalangiana do hálux, suas indicações atuais e as opções de tratamento. MÉTODOS: Realizamos uma revisão da literatura de estudos clínicos relevantes em múltiplas bases de dados, incluindo PubMed, MedLine e Scopus, de janeiro de 1989 a outubro de 2020. RESULTADOS: Há consenso para o tratamento cirúrgico de fraturas intra-articulares com desvio superior a 2 mm, fraturas metadiafisárias com má rotação e/ou malangulação, fraturas expostas e fraturas instáveis. CONCLUSÃO: O uso de implantes mais rígidos permite a manutenção do alinhamento durante o processo de consolidação e menor risco de perda da redução. As complicações que devem ser evitadas são a deformidade em valgo e a osteoartrite da articulação interfalangeana. Nível de Evidência III, Revisão sistemática de Estudos de Nível III.
ABSTRACT
The association of ipsilateral talar and calcaneal fractures is an uncommon combination and is typically the result of a high-energy trauma. It is often associated with comminution, marked fracture displacement, and soft-tissue compromise. Obtaining satisfactory clinical and radiographic results is very challenging. Residual deformities, multiple procedures, and limitations are usually the norm. Therefore, studies have suggested that primary arthrodesis may represent the best option of surgical treatment. In this study, we report a case of a 30-year-old male patient with a rare combination of a highly comminuted transcalcaneal fracture-dislocation associated with a talar neck fracture successfully treated with open reduction and internal fixation (ORIF) with an 18-month follow-up. This case demonstrates that even when there are associated fractures of the talus and calcaneus with severe bone loss, ORIF may provide satisfactory outcomes in the short-term postoperative period.Levels of Evidence: Level V: Case report.

OBJECTIVE: To determine the areas presenting risk in six zones of the calcaneus, and to quantify the risks of injury to the anatomical structures (artery, vein, nerve and tendon). METHOD: Fifty-three calcanei from cadavers were used, divided into three zones and each subdivided in two areas (upper and lower) by means of a longitudinal line through the calcaneus. The risk of injury to the anatomical structures in relation to each Kirschner wire was determined using a graded system according to the Licht classification. The total risk of injury to the anatomical structures through placement of more than one wire was quantified using the additive law of probabilities and the product law for independent events. RESULTS: The injury risk calculation according to the Licht classification showed that the highest risk of injury to the artery or vein was in zone IA (43%), in relation to injuries to nerves and tendons (13% and 0%, respectively). CONCLUSION: This study made it possible to identify the most vulnerable anatomical structures and quantify the risk of injury to the calcaneus.
ABSTRACT
OBJETIVO: Determinar as áreas de risco em seis zonas do calcanhar e quantificar os riscos de lesão das estruturas anatômicas (artéria, veia, nervo e tendão). MÉTODO: Foram utilizados 53 calcâneos de cadáveres divididos em três zonas e subdivididas em duas áreas, superior e inferior, por meio de uma linha longitudinal do calcâneo. O risco de lesão das estruturas anatômicas em relação a cada fio de Kirschner foi determinado pelo sistema de graduação segundo a classificação de Licht. A quantificação do risco total de lesão das estruturas anatômicas na colocação de mais de um fio foi calculada pela lei aditiva das probabilidades e pela lei do produto para eventos independentes. RESULTADOS: O cálculo dos riscos de lesão, segundo a classificação de Licht, demonstrou que o risco de lesão da artéria ou veia na zona IA é mais expressivo (43%) em relação às lesões de nervo e tendão (13 e 0%, respectivamente). CONCLUSÃO: O estudo permitiu identificar as estruturas anatômicas mais vulneráveis e quantificar o risco de lesão no calcanhar.

Tibial plateau fractures are joint lesions that require anatomical reduction of joint surface and functional restoration of mechanical axis of a lower limb. Patient profile, soft tissue conditions, presence of associated injuries and the available infrastructure for the treatment all contribute to the decision making about the best treatment for these fractures. High-energy fractures are usually approached in a staged manner respecting the principle of damage control, and are primarily targeted to maintain limb alignment while the resolution unfavorable soft tissue conditions is pending. Low-energy trauma can be managed on a singlestage basis, provided soft tissues are not an adverse factor, with open reduction and internal fixation. Stable fixation and early painless joint movement are related to a better prognosis. New developments as locked plates, bone replacements, intraoperative 3D imaging are promising and will certainly contribute for less invasive procedures and better outcomes.
ABSTRACT
As fraturas do planalto tibial são lesões articulares cujos princípios de tratamento envolvem a redução anatômica da superfície articular e a restauração funcional do eixo mecânico do membro inferior. Contribuem para a tomada de decisões no tratamento dessas fraturas o perfil do paciente, as condições do envelope de tecidos moles, a existência de outros traumatismos associados e a infraestrutura disponível para abordagens cirúrgicas. Para as fraturas de alta energia, o tratamento estagiado, seguindo o princípio do controle de danos, tem como prioridade a manutenção do alinhamento do membro enquanto se aguarda a resolução das más condições de tecidos moles. Já nos traumas de baixa energia, desde que os tecidos moles não sejam um fator adverso, o tratamento deve ser realizado em tempo único, com osteossíntese definitiva. Fixação estável e movimento precoce são variáveis diretamente relacionadas com os melhores prognósticos. Desenvolvimentos recentes, como os implantes com estabilidade angular, substitutos ósseos e imagens tridimensionais para controle intraoperatório, deverão contribuir para cirurgias menos invasivas e melhores resultados.
