- Congenital Clubfoot - Is the Ponseti Method the Definitive Solution?(2021) CORDEIRO, Felippi Guizardi; MACEDO, Rodrigo Sousa; MASSA, Bruno Sérgio Ferreira; GRANGEIRO, Patricia Moreno; GODOY-SANTOS, Alexandre Leme; FERNANDES, Túlio DinizAbstract Congenital clubfoot is one of the most common deformities at birth. The inadequacy or absence of treatment causes serious limitations for people with this condition. The initial treatment using the Ponseti method ensures functional results superior to other treatment modalities previously proposed. However, recurrences and neglected feet are still a challenge today. An understanding of the pathophysiology of the disease, as well as of the anatomy and local biomechanics and a thorough clinical and radiological evaluation of patients are essential to understanding the limits of the method and choosing the best treatment.
- Ankle Osteoarthritis(2021) GODOY-SANTOS, Alexandre Leme; FONSECA, Lucas Furtado; CESAR NETTO, Cesar de; GIORDANO, Vincenzo; VALDERRABANO, Victor; RAMMELT, StefanAbstract Osteoarthritis (OA) is characterized by a chronic, progressive and irreversible degradation of the joint surface associated with joint inflammation. The main etiology of ankle OA is post-traumatic and its prevalence is higher among young and obese people. Despite advances in the treatment of fractures around the ankle, the overall risk of developing posttraumatic ankle OA after 20 years is almost 40%, especially in Weber type B and C bimalleolar fractures and in fractures involving the posterior tibial border. In talus fractures, this prevalence approaches 100%, depending on the severity of the lesion and the time of follow-up. In this context, the current understanding of the molecular signaling pathways involved in senescence and chondrocyte apoptosis is fundamental. The treatment of ankle OA is staged and guided by the classification systems and local and patient conditions. The main problems are the limited ability to regenerate articular cartilage, low blood supply, and a shortage of progenitor stem cells. The present update summarizes recent scientific evidence of post-traumatic ankle OA with a major focus on changes of the synovia, cartilage and synovial fluid; as well as the epidemiology, pathophysiology, clinical implications, treatment options and potential targets for therapeutic agents.
